What is two-way radio communication? Radio communication is a simple, convenient, reliable way of two-way communication and transmission of information between mobile and stationary objects using two-way radios and walkie-talkies (transceivers), by which voice is transmitted via radio frequencies. In the 1960s – 1990s, this was the only way to get a voice communication without wires. Since the 90s, mobile phones have occupied a part of the niche of two-way radio communications, but it is still continuing to be used by professionals in the workplace, transport, city services, the military, police, by the security guards, doctors, and by ordinary citizens.
Thanks to these advantages, the two-way radio solutions continue to be used by all the people who need reliable, simple and inexpensive, operational voice communication.
Which model of two-way radio to choose?
It depends on the goal. Let's consider a few typical cases.
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.
In the case when the communications are necessary on the road (for travelers, campers, and especially for professional truck and bus drivers), it is better to install a 27 MHz (CB - Citizen Band) car two-way radio in the vehicle . With a good outdoor antenna, such as radio can provide communication over a distance of tens of kilometers. Transceivers of this type may also be used without special permission in most European countries*. Since such radios are installed on many cars, a large CB radio user community has emerged. On whatever road you are on, you can always hear messages from other drivers: about the traffic situation, accidents, weather conditions and local events. Even if you are traveling by oneself, you will not be alone on the road. As a rule, local operational services are always on duty at one of the channels. Thus, in an emergency, you can count on quick help - from other drivers or from operational services. Similar devices are recommended for tractors and combines in the fields. For a good start, we can recommend a simple and reliable CB transceiver of the lower price range - Luiton LT-298 (check out on Promarket-eu or amazon.co.uk, amazon.it, amazon.fr, amazon.de, amazon.es). The radio has advanced reception and transmission characteristics; the frequency range can be configured for use in different countries. Certified for use in the European Union.
* Specific permitted frequencies and legal requirements for unlicensed equipment may be specified for each country where you plan to use the radio. Although there is no need for permission, in some countries registration or a declaration in a simplified form is required.
