Radio Communication Systems and Equipment
It is a matter of fact that this world is fast paced. There are many things which are highly responsible in order to make this world reach that kind of pace. One such thing which has played a vital role in this case is the two way radio communication, which is possible with the radio communication systems and equipments. Well, actually speaking, we have to thank two way radio communication, as it will help us to communicate with people who are far away from us. In addition, you will also enjoy a kind of ease and clarity when you are communicating.
The two way radio communication has helped people or companies to be highly benefited. In fact, it has made a very complicated thing to look so simple, without wasting much money as well as time. The two radio communication systems and equipments will help all sorts of employees to be in touch with their fellow mates at any instant. The radio equipments are out there to set a milestone in world of communication. Since the radio communication system is enabled with two way radio communicating, employees can easily be in touch. In fact, you will find many huge industries, which are well equipped with radio communicating systems in order to guide as well as to manage their employees. Since the supervisors cannot afford to monitor and guide their employee being in the same place every time, the two way radio communicating will get their work done with the comfort of their cabin. Hence, it helps to get the task done without any sort of risks and tensions.
It is great to see that there are several companies out there both online as well as offline, which are offering these systems for hiring during the special events. You can look forward to hiring these systems for any special events. These companies will also offer amazing discounts for those willing to hire or purchase radio communicating systems. It is always advised to go through the online reviews of the companies offering these services in order to pick the right company. However, for those who are looking to get the radio communication systems installed to their office or homes in order to enjoy a great convenience, it is always advised to get them installed with the guidance of a systems expert. If you call them before and let them know the purpose of which system you are installing, they will choose a right system considering various factors such as the frequency required, power sources available etc. They will get started with the installation work as soon as you finalize the deal with them. Since they are also wireless, it will not be that difficult to maintain these systems.
In the security point of view, no provider will guarantee you that kind of security, which radio communication systems/equipments do. You can look forward to getting your business or house monitored 24 hours only by making the most of these systems.
Botswana: HF fixed radios
Since its independence in 1966, Botswana is experiencing harmony, stability and excellent economic growth. The commercially exploited diamonds found in Botswana is a source of its economic and geological wealth. Many foreign investors and social workers have shown great interest in the growth of this country. The need for powerful networking and communication is thus the need of the hour in Botswana. HF fixed radios, and vehicle mount communication systems are of great importance to workers who have to go deep into the country side.
The HF fixed radios come in different models according to the usage and the need. In desert areas or in mines communication is impossible without the help of powerful network systems. Governments as well as private organizations are always looking for flexible, cost effective and reliable communication systems for remote access mostly during times of emergency. High frequency radios are preferred from normal networks for these urgent and reliable communication needs.
Instant voice, instant messaging, email, fax and GPS navigation are some of the features of HF Fixed radio and vehicle mounted communication systems. Community workers and miners who have to travel to remote areas in Botswana will find this HF fixed radio reliable and really very useful in times of emergency. The government and other organizations need the vehicle mounted HF radios to keep up the constant and consistent network for transfer of important data and messages.
Fixed base stations are used for controlling the mobile and portable communication networks. HF fixed radio network need minimum infrastructure and hence considered as best suited during times of disaster and emergency. The cost for this form of network is also very nominal when compared to other communication network systems. HF radios are very tough so as to withstand any extreme condition and are also very cost effective.
The fact that the military uses these HF radios shows that this communication system has secured and reliable networks wherein the data and the voice messages are encrypted and secured using the latest technologies. Simultaneous communication among a group or many operators is possible in HF fixed radios. This is one reason why it is said to be most effective for disaster control and management as it can easily and quickly connect with any number of operators simultaneously.
HF radio base stations can also connect to VHF and UHF radio systems. It can also work along cellular phones and land line telephones also. It is simple to operate and can be carried and operated at any place or location with less hassle. This is what has made the HF fixed radio base stations and vehicle mounted networks a necessity in Botswana. Economically developing country like Botswana can rely on such high frequency, cost effective communication systems for all its development and emergency needs. The government and the military will find it very useful during riot and disaster control. Local police and security services can use these HF radios to control crimes in the country.

Command Control Systems
What is a command control system?
What are the significant features of this command control system?
Global command and control systems are nothing but a collection of SOA systems. It was originally developed with the view to replace the worldwide military command and control system. It is used by US navy and Marine Corps, US army and Air force. Some significant features include intelligence analysis, combat operations support, radar and ground weapons analysis, targeting etc using the web services. It can also provide terrain and weather forecast. Further advance in this technology might enable chat, emails and newsgroups as well.
The command and control system uses IP based connectivity or NIPRNet, JWICS etc. this system can collect nearly 94 sources of different data’s. It is trusted as one of the best communication system for the enhanced security purposes. The nation’s safety lies in the performance of these control system as a slight fault might endanger the nation’s security. The data or message to be delivered must be confidential, fast and immediate. Thus an effective system which can provide all the three functions should be considered and the best. The military, air force and navy should also be able to co ordinate their action in times of war. So an effective system to combine and combat the three sectors is imperative.
High command officers always need to share high security messages or data. The quickest way to transmit these messages with minimal loss or theft is through the command control system. The system should be very strongly protected to face the threats from hackers and deadly viruses as the system uses the web services. It must provide accurate reports and the analysis should be true and dependable. If the chat and email options are provided then the communication within the army or navy is always open and inter connected for quick data or message transfer. It can easily identify the radar signals or the approaching security threat in no time. The message thus delivered will be very useful to protect the country and the people in it. The command and control system is thus dependable, reliable, trust worthy, highly rated for performance and can be used any where and every where. The communication systems are updated regularly and newer options and features are also introduced to keep in pace with the changing times.

Milipol Paris 2009
The Milipol exhibition commences on the 17th November and completes 20th November, 2009. For the first time Communication Specialists Ltd will be attending the Milipol exhibition, presenting our new product range in the security sector. We will also be showcasing our two way radio product range that supports the needs of the Military, Police, MOD, businesses and the end user.
Come and visit us on our SESP Stand Number 13C004 and MIB Electronics stand Number 11.L.089 - see you there!
At the end of the 70s, various French manufacturers supplying police equipment were worried that they had limited commercial contacts at international level. Contrary to the Aeronautics and Defence sectors, the Interior Security sector did not have any promotion and communications platform that matched its importance in France. As a result, the idea of organising a specific international exhibition took hold. EXPOL (EXposition POLice), the first private initiative, showed the way.
In 1984, the International Milipol Committee came to life as an association whose goal was the promotion of security techniques and equipment.
That same year, the first international Milipol Show was organised in Paris as the privileged information and public-relations tool, open widely to professionals in the field of security, including manufacturers, end-users, buyers and exhibitors of all nationalities. The quasi-confidential field of police, civil and military security equipment, virtually unknown to the general public until that time, was thus brought to light.
While the subsiding cold war still held centre stage, security services were already at work in the wings, fighting against such growing menaces as criminality, drugs, organised crime, terrorism, industrial and economic espionage. They expressed their latest requirements and needs for equipment, while investigating all the techniques available.
The Milipol Show evolved within this climate of expectation and demand. It broadened out to include the field of security which encompasses private and public communities, that of industry and businesses, the protection of populations, and internal State security.
Held annually during the 80s, the Milipol Paris Show found its cruising speed as of 1991, the year in which the biennial scheduling was adopted.
In 1995, it acquired new dimensions of considerable importance.
As it was now held under the aegis of the French Ministry of the Interior, the Milipol Paris Show became an official event, along the same lines as the international Eurosatory exhibitions for land armament, Euronaval for naval equipment and the Paris-Le Bourget Aeronautics-Aerospace Exibition.
Today, the international Milipol Trade Show compels recognition as a result of its professionalism and the quality of its exhibitors and visitors attending from around the world, all genuinely linked to the various security sectors.
The Milipol brand is owned by a group of companies - COFREXPORT, PROTECOP, THALES, VISIOM and CIVI.POL Conseil, a consultancy and service company of the French Ministry of the Interior.
The exhibition is organised by EDS Milipol.

Those wishing to take part in the 2010 Army Telemark championships should read the DIN and complete the included entry form.
Many of you reading this may not even know what Telemark Skiing is, so, let's go back in time and give you some background history on Telemark Skiing and the British Army Association.
Where did the Telemark come from?
Telemark skiing was introduced in 1868 by Sondre Norheim of Norway, it is also referred to as free heel skiing which is a technique focused around the Telemark turn. This type of skiing has steadily regained popularity since the 1970s.
What is Telemarking?
The Telemark turn is a skiing technique that allows for fast, smooth and stable turns on a variety of surfaces. Telemark skiers have cable bindings, which allow the heel to rise during turns - hence the term 'free heel' skiing. Telemark skiing is therefore characterised by the 'telemark turn', in which the outside ski leads in the turn and the inside ski trails, with the knee bent and the heel raised. (By contrast, Alpine skiers' boots are fastened firmly to their skis and the inside ski leads in the turn.)
History of Telemarking Skiing
Telemarking Skiing has been called "the world's oldest new sport". Telemark has also been referred to as "the most rhythmic and flowing way to descend snow covered mountains". Telemark skiing is all about the stroke, sensation and the feeling of excited exhilaration that comes from getting into the grove of the tele turn. The true stoke of Telemarking is hard to describe. It can be an almost ethereal experience in those moments when everything comes together: form, function, time and space.
In 1868, Norheim and a group of skiers from Telemark travelled to the city of Christiania (now Oslo) to take part in the second annual Centralforeningen (Central Ski Association), a ski competition the object of which was to see who could ski most skilfully down a particular nearby slope in the city . At the time, nearly all skiers were straight running everything, and struggled to make any kind of turn. At the competition, Norheim and the other villagers shocked the city skiers, demonstrating skills that had never been seen before, including strong turns and precisely controlled stops.
Who Are the ATSA?
ATSA was set up in 2007 to provide a focal point for Telemark skiing at all levels within the British Army.
The Aim of ATSA:
- Encourage new telemarkers to get involved
- Run an annual Army Telemark championships in Austria. (This is open to Royal Navy, RAF, UK Civilian and other military competitors. In 2010 we will also host a world cup telemark event.)
- Send a British Army team to the Inter Services Championships
- Support GB Telemark - the focus for the British national team

Transmitters
Have you wondered where this world would end up without communication? It is very hard to even conceive what will happen to mankind when every mode of communication stops working. The very thought is frightening and the whole world will no doubt be in great chaos. Two way radio Communication helps in sharing or informing the latest happenings and the news around the world. It is used vastly for personal, commercial and security reasons. Hardly anyone leaves home today without his mobile phone. In order to have uninterrupted communication network effective transmitters are used.
What are transmitters and why are they considered so important in the world of two way radio communication? A Transmitter is an electronic device which with the help of the antenna broadcasts electromagnetic signals used for radio, television and telecommunication. To make it simple, a transmitter sends information to the receiver through objects like antennas, towers etc. We generally call our mobile handsets, receivers. The data which is transmitted from another form passes through a network of transmitters before reaching our mobile receiver.
A data from a two way communication network is transmitted from the one place to the satellite and again back to the place it is sent. In this case the satellites work as transmitters by receiving data and converting them and sending them back to the receivers. This transmitted data cannot be said as safe as anyone with little knowledge on hacking this data can easily steal them. This generally happens with highly secretive emergency communication by the armed, air or naval forces.
The security communication systems used highly powerful transmitters whose frequency cannot be reachable. Moreover many governments have introduced strict laws against this danger and the risk of highly secured data being stolen. Industrial sector uses transmitters for its process control. But these transmitters are used to convert the sensors measurement into signals. These measurements from sensors are sent through wires to distant receivers. It uses digital protocol to measure variables in a range.
Alexander alternator or mechanical alternator was used in the olden days for radio, engineering and frequency. Later, vacuum tubes were used as transmitters in the 1020’s. After a lot of advancement and evolution transmitters today are capable of handling huge volumes of data transfers and are encrypted and secured. These are fed from high voltage power supply to ensure security. The possible risks to transmitters are lightning and hence the transmitters must be well protected.
Without antennas the transmitters can be damaged so all steps must be taken to ensure the safety of the transmitters. Protection must also be provided from high voltage and correct voltage of current. During times of lightning the transmitters must be switched off immediately. At the same time the place or building on which the transmitters are set up are also very important. Thus for an efficient working of a high power transmitter proper safety and security measures must be taken. Transmitters are very imperative for all types of two way radio communication systems.
Transceivers
The world has become a global village because of the advancement in the two way radio communication systems. Anyone living in the remotest part of the world can share his knowledge or information within seconds with the rest of the world. The electronic media is growing in leaps and bounds and we cannot even imagine what a life our ancestors have been leading, without electricity, mobiles or the internet. All these gadgets and gizmos have become a part of our lives so much so that our kids feel it is a very important part of their communications. Any form of communication medium needs a receiver and a transmitter. But a transceiver can do the job of both the transmitter and the receiver.
What is actually the job of the transceiver? How can it be useful with the two way radio communication systems? A transceiver combines into a common circuitry both the receiver and the transmitter, and this term came into process from the 1920’s. When the transceivers don’t have a common circuitry it is called transmitter-receiver. But technically speaking every transceiver must have part of both the receiver and transmitter. There are other similar devices like transverters, repeaters and transponders. One best example of a transceiver is the mobile phone wherein the whole unit contains the transceiver, whereas the normal telephone has wired receiver and transmitter in its handset.
A modem and cordless telephones are also best examples of the transceivers. Cable or optical fiber systems also use these devices. In a radio the transceivers role is imperative. The receiver goes into silent mode while transmitting. The switch of the radio connects both the receiver and transmitter to the antenna which in turn stops the transmitter from damaging the receiver. In this so called half duplex mode receiving signals is not possible while transmitting as both the functions are done in the same frequency.
In the full duplex mode the transceivers can transmit and receive signals at the same time, as they operate on totally two different frequencies. In this case both the signals do not intercept one another. This full duplex mode is what is used in cellular and cordless phones. Almost all satellite dependant communication systems use the full duplex mode of transceivers. In this case the transmitted signal to the satellite is otherwise known as uplink and the received signal from the satellite is called the downlink. Many different types of transceivers are being invented tested and used from time to time.
The cost of the transceivers depends upon its usage and capability to handle the amount of work transmitted and received. Whatever the price the role of transceivers in two way radio communication systems is imperative. Today most of the people cannot live without their mobiles and they find it hard to use fixed landline telephones. The telephone operators introduce cordless, wireless phones for customer friendly feature and this is best made use of by the customers. In today’s fast world transceivers enabled devices are user friendly, powerful and performance driven. Newer technologies will enhance the user experience more and more in future.
Secure Communications
Today we use quiet a lot of two way radio communication mediums to share personal and business details. Are you sure this data or information shared is secure? Who can guarantee the security of the systems we use in our day to day lives? How can we secure our communication systems from possible hackers or virtual thieves? The answers to these questions depends upon the type of communication system we use, its purpose in our lives and the role it plays to help us do the work we intent to do using them.
Communication is imperative among humans and so it is among other living beings too. So man developed a language through which he started sharing his thoughts. Initially it was commuted through hand signals or actions. Then words, sentences and finally a proper fully fledged language were formed for communication purpose. This differed from region to region and from country to country. Still a limitation was existent as all people couldn't understand other languages and only the people nearby were able to commute. This started off the fire of communication which later evolved and is finally in a state today where even the remotest person living in Antarctica can call Japan in few seconds.
Coming back to secured two way radio communication, the more man depended on communication the need for its security also became imperative. When two people shared something important they expect their messages to be private and safe. So they started using security devices to safeguard the communication systems from being hacked by third parties. Normal everyday communication has some security and we do trust that no one is tapping our calls. When communication is done for more serious matters then special care should be taken to increase the security mode of the device that we use. Mostly commercial and military operations need secured two way radio communication systems. In recent years we hear so much about top secret messages from government or military sources being intercepted by terrorists. The same happens the other way too wherein the military or police intercept the enemy connections.
During the Second World War a highly effective secured communication was used between Winston Churchill and US President Roosevelt. This secured communication was called Green Hornet. Initially they were talking through radio phones which were easily overheard by the Nazis. It was then that the Green Hornet was introduced. Whoever tried to intercept would just hear white voices. The clear original message was heard only by the two users. Different types of security are, coded, encryption, steganography etc. other security threats include Trojan horses, spy ware and viruses. These can be easily taken care of by antivirus software, registry checkers and firewalls. These are generally termed as computer security. A well protected two way radio communication is stress free and the large institution and research centers can relax due to their safe communication network. Today virus attacks are common even in mobile phones. They are transmitted through Bluetooth file transfer facilities. Secure communication is no doubt imperative for all communication needs.

Mobile Tactical Communications
Military communications need to be integrated as there are many manned, unmanned devices working in tandem with the infantry and other units of the army – in the highly isolated areas like a battle field or a disaster affected area. Proper conduction of an operation requires effective communication. Making mobile tactical communications inevitable – this requires an interoperable system which works with tactical radios, local area networks and wide area networks. These systems are stand alone which can function with the help of the technology the mobile phones work on using the GSM, GPRS and satellite technologies or the humble two way radio which used the electromagnetic waves to convey messages. The Morse code though obsolete should not be forgotten.
Mobile tactical communications came in handy during the various terrorist attacks like the 9/11 of the world trade centre when the commercial cellular lines were hit in the epicentre and the hurricane Katrina too. Mobile tactile communications can help connect to the outside world and save lives – when someone’s injured and requires hospitalization, as for help when completely surrounded by enemy, call for food and medicines for the people marooned in floods and similar situations.
Mobile tactile communications are not only the requirement of the army but also the rangers of the forests, the rescue workers of the areas affected by the natural disasters, police and other government officials, social workers, and the common man. When there are billions of dollars being spent on advancement and development of technology and other facilities the development of the mobile tactical communications will change the way we all communicate – it uses the radio the voice over the internet protocol and other intelligent and commonly available technologies.
When war-like conditions arise at a terrorist attack or a natural disaster all communication links get jammed then the mobile tactical communications are the answer to the need of the moment as these technologies will help keep in touch with loved ones. The cables, the communication hubs, the usual modes of communication could be affected or as the lines are jammed more communication options may be required or a platform to streamline the rescue or other operations may be required to instruct people and public in general at such times the high and multi-frequency mobile tactical communications would be very effective. The hurt and the injured may require medical attention – call for land and air ambulances, fire brigades, medical emergency vans and law enforcement agencies would be made easy and timely in the hour of need.
Mobile tactical communications are the need of the hour and should be posted at focal point throughout the cities to help communicate at the times when other communication devices have suffered damage or overload.
Military Radio Aerials
Military radio aerials are wire of structure arranged such that it generates and radiates the electromagnetic waves when an alternating current is applied. Their size too differs according to the type of system being used; they are even mounted on bionic bugs to spy on enemies. Most military radio systems and military radio aerials give undeterred comm-links.
Usually amateur radios are used in military comms – these are mostly used for emergency needs. Amateur radio is not dependent on the local or terrestrial facilities as they sometimes fail. The military radio aerials improvise a signal which ensures a regular dependable performance and all times from any place on the earth as long as the frequency is known. This makes them ideal for use during disaster relief and other remote operations.
These can be used at the time of active war & terrorist attacks; they ensure safety from commercial and industrial espionage and safe communication to research institutions, etc. Military radio aerials are very powerful and can meet the diverse needs of the military forces and other institutions.
Military radio aerials are secure to use because as soon as war breaks out the enemies first target is to cripple the communication system as a part of the strategy to isolate the enemy. Aerials are stand-alone, light and portable. The difference between an antenna and an aerial is that an antenna is a large metallic structure, known as a transceiver as opposed to an aerial which is a wire which can be held in any direction to facilitate communication – in fact it can be adjusted to transmit and receive radio frequencies just like it elder larger cousin. There are different kinds of aerials – a single vertical aerial that transmits signals at 360 degrees or in the form of a sphere. There are mobile aerials on cars, truck, cell phones and radio aerials which transmit in different patterns due to which the different radio channels at different frequencies are possible.
Military radio aerials have different frequency receptions and capacities depending upon the type of communication system installed. The best communication system is when the signals are sent and received in an uninterrupted manner even in places like underground bunkers, through thick rocks and caves or other remote locations like the tops of mountains and deep cervices in the hills, on the high and deep seas in the submarines.
Generally huge reception antennas are used for the base stations but the military radio aerials are ideal for the operations on temporary or mobile bases as they are light weight, easy to carry and setup, thus very crucial for military ops.

Communication Systems: Microwave Receivers
- Buy Codan Digital Microwave Ethernet
- Buy Digital Microwave Radio
There are simply a variety of receivers out there that has many uses. One receiver type that comes to my mind that I think I need to discuss is the Microwave Receivers, it is a common receiver that is used to amplify weak signals that antennas, radios or any communication systems gather. So, basically Microwave Receivers is all about gathering weak signals or in some terms weak frequencies to make ends meet in broadcasting. Most people take a swing at it because they claim that the name itself confuses them. Microwave Receivers can be a funny name for a receiver because we have the common knowledge that a Microwave is an oven that we use at home to cook meals and mixing it with a technical term like receiver paints an awkward picture on people’s minds. So, I am here to further discuss some few things regarding Microwave Receivers.
First and foremost as I have defined in the early parts of this article, Microwave Receivers are receivers that amplify or modify signals that it gathers from basic communication and broadcasting systems or gadgets. It gives the reception a stronger impulse thus making the signal or frequency stronger. Some people might not understand this but it is really a device which makes your signals stronger.
Learning more about Microwave Receivers, you also need to know more about receiver terminologies such as baseband frequency, or when the receiver uses a mixer, you need to know something about RF, IF and LO frequencies etc. Well, to tell you the truth it isn’t really required to study most of them as long as you have an idea what they are. Microwave Receivers is commonly used these days because most technology or communication systems rely heavily on signals.
The internet technology for example uses broadband connection, in order to make the signals stronger and more reliable, microwave receivers come in to play to amplify it, WiFi signals and others also require microwave receivers to help them have a better distribution of frequency or signal. It is basically an important part of today’s communication engineering. Most microwave engineers tackle the importance of knowing more about these receivers in order for people to further have a broad understanding not only about microwave receivers and also how it operates. The distribution of signals to most locations can be limited, like in broadcasting for satellite dishes it doesn’t really gives you a big clear picture once the signal is relatively weak, so what happen is microwave receivers comes to the scene to give you a clearer picture.
We all need to be at least aware on what microwave receivers do, so that we would be knowledgeable on how things work around our communication systems. The realm of engineering can be really broad depending on what you need to know. Microwave Receivers should not be taken for granted and/or snubbed. We need to make our own understanding in certain terminologies that affect our everyday lives and technology such as microwave receivers¸ we need to be well informed so that we know what we are dealing with in our own communication systems.

Two Way Radios: Message Encryption
Basically when we hear Message Encryption we automatically think that it is about how to encrypt messages to send to other party. Well, it is literally correct but looking to it in a more technical way, Message Encryption is something far more important than just a simple encryption of messages in letters. In the techie side of it, Message Encryption it is the process of encoding data in an encryption to prevent unauthorised access from the outside and to have more security on the data that you are trying to send or keep. It basically keeps the message from being read by converting the content into cipher or scrambled letters or characters so that the privacy of the message can be kept. Message Encryption is a method in which the only one who can read the message is the recipient (Other than the sender). In which the encrypted or ciphered message will be deciphered by the recipient.
Any other attachments to the encrypted message are also ciphered but do not worry there is a way to decipher it or there are instructions for it to be deciphered. Message Encryption is one of the most used methods to continue and to preserve the security and privacy of the message being sent to the other party. In technology, especially in information technology, Message Encryption is being often used from the very basic emails to more complicated software encryptions. But it is more commonly used to pass messages and to send and hide important information or data in a server. Message Encryption can be commonly seen in websites that promotes security or to messages that has private content to it.
In a more vivid way, Message Encryption is used by administrators of websites in which codes the messages that they are trying to preserve, especially in shopping networks or websites, the use Message Encryption on credit card information or delicate user information and even website security as well. It is one of the safest ways to preserve the content of a website or in simpler occasion the messages itself. If you want to know and learn more about Message Encryption it is actually not hard at all, all you need to do is research more about Message Encryption and from there you can find basic ways and even downloadable software that allows you to encrypt and decrypt a message with no hassle.
Message Encryption is a very nice option for people who loves their privacy and for people who wants to have an exclusive way of sending messages to private people that they are doing businesses or just having private conversations with. To dig more on Message Encryption you can easily go to any search engines and type the keywords “Message Encryption” and from there you’ll see various information about Message Encryption that can thoroughly help you on your way to understand and learn more about Message Encryption, it is really a good thing to learn more about it and if you want to be in the know on these kinds of things, I suggest you get on your research hat and start getting valuable info about it.

Walkie Talkies for Schools
Children of all ages are sent for their education to schools and thus they spend a lot of time inside the school campus. The safety and security of these kids should thus be the highest priority for the institutions, which in all ways is responsible for their safety inside the campus. Communication and co –ordination between the various staff and teachers is thus very imperative.
It is impossible to personally send or receive messages, especially when the school is big and covers many buildings or dormitories. At the same time fixing a telephone in each block or even in each class is time and cost consuming task.
Moreover, there is no surety that the lines will always work. The best form of communication in terms of time and cost is the Walkie talkie. Walkie talkies are hand held radio receiver, which can be carried by all within the vicinity of the school campus.
To help you decide what type of two way radio would be suitable for your school you have to take into consideration the distances involved as to which radio can be used. If the campus is not too large, then any license free radio will do, i.e., Kenwood TK-3201, Motorola XTNi (business type license free) or the smaller, cheaper “consumer” radios, such as Motorola XTR446, TLKR T3 or TLKR T7.
Normally we would advise the Kenwood TK-3201 or XTNi as these are very robust.
Alternatively, if the area is larger the school would need to obtain a radio license. Then it would be any number of radios, Motorola CP040, Motorola GP340, Motorola GP344 and so on.

What is a Two Way Radio?
Two-way radios, more commonly known as walkie-talkies, were originally developed for the Canadian government during the Second World War by Canadian Donald L. Hings. Similar designs were created for other armed forces, and after the war, two-way radios spread to public safety and eventually commercial and jobsite work.
Major characteristics include a half-duplex channel, where only one radio transmits at a time, though any number can listen, and a push-to-talk switch that starts transmission. Typical two-way radios resemble a telephone handset, possibly slightly larger but still a single unit, with an antenna sticking out of the top. Where a phone's earpiece is only loud enough to be heard by the user, a two-way radio’s built-in speaker can be heard by the user and those in his immediate vicinity. Hand-held transceivers may be used to communicate between each other, or to vehicle-mounted or base stations.Finish reading this article on two way radios on our website
