A two-way radio, also known as a transceiver, is a device that allows communication between two or more individuals through the use of radio frequency transmission. These devices are commonly used in a variety of settings, including:

- Business and industry (e.g. construction, manufacturing, retail) for communication between employees

- Public safety and emergency services (e.g. police, fire, and ambulance) for coordination and communication during operations

- Outdoor recreational activities (e.g. hiking, camping, and hunting) for communication between group members

- Transportation (e.g. trucking, shipping, and aviation) for coordination and communication between vehicles and dispatchers

- Military for communication between soldiers, tanks, aircraft, and other equipment.

Two-way radios are often preferred over cellular phones in certain situations due to their longer range and ability to work in areas without cell coverage. Two-way radios are commonly used in situations where direct communication is needed and cell phone coverage is limited or unavailable. Two-way radios allow for instant communication and coordination among team members, which can help to improve efficiency and safety.
