How Do Two Way Radios Work?
A two-way radio (also known as a two-way radios, 2-way radios, walkie-talkies, etc.) is a basic radio that will both receive and transmit radio waves, rather than just receiving radio waves. It’s a basic transceiver, a transmitter and receiver in a single unit, used mostly for bidirectional, personal communication with other wireless users with similar devices. The number of channels (or radios) that are on a typical system will depend on the radio being used; generally, there are from three to seven channels on most systems.
Even though a two-way radio may be a simple device, it does have some fairly sophisticated components. The most basic radio will have a station, much like a landline phone, with a dedicated frequency. These frequencies will generally be in the range of five to seven megahertz, with the range going up to 100 megahertz in some case. The range of the radio will be determined by the type of signal that the transmitter is using. Landline phones and telephone lines tend to work well within this range of frequencies.
There are various types of devices that may be required to use this technology. For example, in the farming sector, it would be more likely to need a higher bandwidth, since cattle are usually kept in pens or stables. These types of mobile radios will allow the owner to send information (such as the status of their animals, harvested meat, milk, etc.) at the same time receiving the information (such as the current location of the animals). However, the higher the bandwidth allowed, the more costly the unit will be.
