Case 1
Limited area
Suppose you need to establish operational communication in a relatively small area of a building or territory - in a group of tourists, security guards, employees of an enterprise or agricultural farm. In this case, portable radio will be a right fit. Without permission and license in most European countries* you can use transceivers of the PMR frequency range (446 MHz). The PMR radios are also successfully used for fast communication in hotels, shops, shopping centers, restaurants, cafes, warehouses and parking lots. The communication range will be determined by the characteristics of the device (mainly power), the density of the building, the terrain, as well as the level of interference in the air. For the low-cost radio PMR 446 MHz range, the operational distance would be from hundreds of meters to some kilometers. An example of a simple, economical and reliable walkie-talkie in this range is the Luiton LT-458 (check out on Promarket-eu or amazon.co.uk , amazon.it, amazon.fr, amazon.de, amazon.es). The radio is well tested in the different weather conditions and under the harsh working circumstances. The radio has a minimum of buttons. To start working with it, you do not even need an manual. Unlike many "indoor use" walkie-talkies, LT-458 is built in a rugged, impact-resistant polycarbonate case with an aluminum frame. Equipped with a Li-Ion battery. Certified for use in the European Union. ) .
