A two-way radio is also known as a transceiver. The radios are used for both sending and receiving data or signals. The radios can either work on analog technology or digital technology. If the analog technology is used in these radios, the transmission can be made clear, even with very weak signals. However, in analog technology, only one thing can be done at any time, ie data can be either air or to be received. When digital technology is used, data can be sent and receivedbut also more data can be sent.
Two-way radios come in two versions. These are simplex and duplex styles. In only a simplex radio channel can be used for an instance. This means that a person can only send data at a time. The most popular type of simplex radio is the walkie talkie. The duplex radio is the one used in the various channels for the transmission of data. This means that anyone can time the use of both send and receive databut with two different channels.
The two radios are two types in general. This is Family Radio Service FRS, and General Mobile Radio Service, GMRS. The family radio service is primarily as a personal radio that will facilitate two-way communication. The area in which these radios can be operated, is two miles. These two radios operate at very low frequencies, so that people in close proximity to communicate with each other. The radios are not suitable for a long seriesCommunication. These stations also have special ribbons on which they operate and not so powerful that it can be used on a daily basis. Additionally, these radios that work best in a line of sight. These stations can not operate very effectively when there is an obstacle or not the land is clear. These types of wireless devices may not work well in the mountains. The Family Radio Service radios are very cheap, especially since they meet the needs of the families are. They have suitable features for the bestpersonal needs.
The General Mobile Radio Service radios are fast replacing the Family Radio Service. One of the main reasons is the fact that the General Mobile Radio Service radios can be effectively used for communication over long distances. These can be within a range of 20 miles. The radios, even for the best, if no obstacles and the terrain is clear. These two radios can not be efficiently used in hilly areas. The radios are very powerful and arebest suited for use in military organizations. These types of radios are expensive and also requires a user with a license to operate these radios.
The radios are equipped with many features. Most of these radios these days have a feature that tells about the weather. These also have functions that are used for navigation. This 2-way radios are normally required to hand and easy to use and comfortable to use and operate.
