Radio Communication Systems and Equipment

As a matter of fact, you can say 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 nothing but the two way radio communication, which is possible with the of radio communication systems/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 as well.

The two way radio communication has helped people or companies to be highly benefited. In fact, it has made a very much complicated thing to look so simple, without wasting much of money as well as time. The two radio communication systems/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 a 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 sorts 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. Hence, you can look forward to hire these systems for any special events. These companies will also offer amazing discounts for those willing to hire or purchase radio communicating systems.

In the security point of view, no service security provider will guarantee you that kind of security, which radio communication systems/equipments do. You can look forward to get your business or house monitored for all 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

Can you ever imagine a world without communication? Communication happens everywhere. Right from the mother earth to the animals, birds and humans, all communicate their messages in one form or another. Communication need not be in words or in a language. Any sound, data, form or character through which the message to be conveyed is transmitted is called a communication process. Today, human modes of communication have grown in leaps and bounds and hardly is it possible to set aside our mobiles or the internet. The whole human security today is based on the effective communication system like the command control systems used in the military.

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!

What is Milipol Paris?
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

Competing in this skiing event are the Army, Navy and The Air Force.

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.
