Two-way radio

Two-way radio(walkie-talkie, Two-way radio, handheld-radio, handheld transceiver, HT) developed in due time by Motorola, in most cases, intended to link the military, and later law enforcement and emergency services.In addition to professional work of law enforcement officers and rescue workers, Two-way radio are widely used in construction, railways, drivers and tourists, fishermen and hunters. These handy tools allows you to make contact and coordinate actions in those places where there is no coverage of mobile operators in terms of vast spaces with poor infrastructure is often a convenient and necessary advantage.Low weight and dimensions of these devices allow them to carry in their pockets and constantly be available for negotiation and coordination.

Most models of Two-way radio provides a range of up to ten kilometers (6,21 miles), which fully satisfies the need for communication while fishing, hunting or hiking. A low weight and dimensions of the radio do not burden users. The characteristics determining the scope of these devices, except for the frequency band and number of channels include range; radiation power; type of housing; Two-way radio Battery capacity. Radiation power devices of this class does not exceed 0.5 watts, which is enough to in a direct line of sight to organize communication at a distance of 6-12 km (3,73-7,46 miles). These figures may be in the real world is much smaller, if they are used in rough terrain, including a large number of buildings in a wooded area, which are seen as obstacles. Two-way radio Battery capacity is usually enough for half a day in active use. It is desirable that this item was replaceable and rechargeable. The body, preferably, they should be sturdy and waterproof. Other features: the number of colors, display, speakerphone and headset increase the usability of the device.The development of wireless communication networks in recent years and cheaper tariffs for the use of competition can create this kind of communication, but as practice shows cellular networks can not provide sufficient efficiency compared to traditional radio, so Two-way radio for a long time will have relevance, to enable them to develop and further.
