TRANSCEIVERS

A transceiver concerns the wide-ranging electronic products that are designed to act as a transmitter and receiver. They also share many circuitry components that are able to function when either transmitting or receiving. Transceivers appear in a variety of types which makes it possible to create a diverse range of merchandise.

Different Types of Transceivers

1. Walkie-talkie Radio
A simple product to incorporate the transceiver includes the two-way radio. A two-way radio comes in a choice of two configurations. This includes either the General Mobile Radio Service (GMRS) or Family Radio Service (FRS). The GMRS walkie-talkie is at the higher end of the scale and power rating. They can include up to 22 channels. The FRS is less powerful and operates with 14 channels (7 GMRS channels and 7 FRS channels). A walkie-talkie offers the ability to communicate between two hand-held devices within a set limit. The communication range can vary. This is often impacted by the number of obstructions that appear between the two hand-held units. A large open area (desserts, fields, plans, etc) with minimal line-of-sight obstructions is certain to offer a greater range compared to those attempting to use the two-way radios in built-up urban areas. Any walkie-talkie within a set range is able to pick up transmissions sent from another device using the same frequency channel.


2. Mobile Phones
A more complex type of transceiver includes the mobile phone. By relying on communication towers and satellites, the mobile phone is capable of sending and receiving data at higher speeds and across greater distance compared to the walkie-talkie radios. They are also able to send and receive data in several different ways. This can relate to streaming data over the internet, multimedia messages (video and photo) and text messages.


3. Rescue Devices
Beyond the standard communication devices, the transceivers are able to help create many other types of devices. A common type of product relates to the search aids, such as the avalanche transceiver. This is highly beneficial for helping those who get caught up in difficulties on the mountains. A device like this is attached to the body to make sure it provides a direct signal to the person experiencing the problems. Each rescue device has two modes, which includes a trigger for receiving and sending an electronic signal. When a person is out on an avalanche-prone area, the rescue device is worn and set to the send mode. A rescuer also has access to a transceiver in receive mode, which makes it possible to find the distressed person.
