A two way radio is a portable radio that can receive and transmit radio signals, unlike a traditional radio transmitter that only transmits radio frequency signals. It is actually a transceiver, an antenna and transmitter in one piece, normally in a portable unit, used primarily for bidirectional voice to person voice communication through multiple users who also have similar radio systems. When multiple users are connected to a two way radio, it can serve as a relay station that relays information or signals to another site in the area where multiple users may be located.
There are many places where two-way radios are being used today. There are schools, businesses and even military bases which use two-way radios for communicating with various units on the ground. Military personnel can communicate with their units through the use of two way radios. Also, in hospitals and clinics, doctors can communicate with patients from different areas and even through the use of a radio.
Two way radios are available in a wide range of prices depending on what you want and where you need them. These radios are available at local electronics stores, and online. They are very popular with business owners because they come in different styles and models to suit any type of business that needs them. They are small in size and are perfect for carrying around in a backpack or on a briefcase.
To be able to purchase a two way radio, there are a few things that you need to consider first. One important thing to consider is the amount of transmission that the device will be required for. If you are just going to be transmitting data back and forth between two sites, then you may not need much more than a simple transmitter to get the job done. However, if you are going to be transmitting a large amount of information back and forth then a more powerful radio may be necessary. There is also the option of using two-way radios with a two way speaker or voice recorder.
Next, you need to determine how much bandwidth you will need in your radio. Bandwidth refers to how much information or frequency that the transceiver can transmit over a certain period of time. You may need more bandwidth if you plan to use it for long distance calls. This means that you will be able to transmit longer messages over shorter distances. This could be necessary if you are using a two way radio for a business that requires multiple contacts in one area. You can increase the number of contacts by having multiple users connect to your radio.
A two way radio also comes in a wide variety of models and brands. You can easily find a cheap two way radio from your local electronics store, and you can find a top of the line units from high end electronics companies such as RCA, Sony and Motorola.
