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.

Communication Systems: BGAN Satellite Phones

Today we are bound to travel a lot all over the world because of the nature of our business. At times we might even end up in places where communication is not easily possible because of the remoteness of a particular area. However, we need to be in constant communication with people from around the world. It might be people from our work or it might be a family that we need to be in constant touch with. This is possible with the technology today which no longer relies on a particular provider or network to provide us with the connection. With satellite technology today we have access to communication systems and links from anywhere around the world to anywhere around the world. This is the biggest advantage of BGAN Satellite Phones.

These phones provide us with connections without any restrictions of area and border. Using the fundamentals of Communications Interoperability these phone help us to reach the people we want from around the world from which ever corner of earth we are on. The phones help us carry out our business without any interruption and let us keep in touch with our family even if we are stuck at some remote location of the planet or in the middle of the sea. This is most beneficial for people who travel a lot for their work. People who have jobs on ships have no account of where they might be tomorrow in the open sea. Therefore, in order to keep in touch with their relatives on shore they can make use of such phones that will connect them with the people they want all over the world.


There are many advantages of such phones with transportable communication systems and features that cannot be matched by any regular phones. Internet is one of the most important things in our lives today even when we consider our job that is mostly done with the help of the internet. Therefore to have internet on the move along with us in any part of the world is defiantly of great assistance to us. Therefore have an internet connection of 492kbps speed along with us when we are deserted in the middle of nowhere is of absolute help to us. With high speed data transfer and data connections, the BGAN Satellite Phones assist those of us who constantly moving around the world.

Since the connection is direct from satellite and not dependant on any local networks the signal is clear and the voice quality is exceptional. Also it is possible to encrypt calls and make discreet calls using this line so that privacy may be obtained for your calls. Video communications are also a major advantage of BGAN Satellite Phones. These video calls are useful for video conferences and other such video communications that are useful to many business people around the world. With the help of a secure dedicated line it is easy to have privacy and easy communication at the same time.
