A two-way radio is similar to a walkie-talkie, but has many advantages. These devices are especially useful when communication is required between large groups. They allow workers to remain on the same page and help keep them safe. Warehouse workers, emergency crews, and security officers all use these types of devices. They also are more reliable than cell phones, making them an excellent choice for areas with little cell phone coverage. Finally, they can be incredibly useful for outdoor workers.
A two-way radio is especially useful for construction workers, who are often on the move, operating heavy machinery, and transporting materials. These workers require professional communication tools that can withstand all of the conditions they face. The best devices for the construction industry are compact and durable, and can handle the high-volume traffic in the field. Two-watt radios are common and usually cover a sufficient area, but larger projects may benefit from larger radios.
Two-way radios were first used during the early 1900s. In the early years of the technology, ships used separate transmitters and receivers to communicate. Early two-way radios did not allow for voice communication, so messages were sent using Morse Code. Today, the majority of two-way radios can support voice communication. You can even use them to communicate with people on the other side of the world. The first two-way radios were commercially used in 1923.
