Licence Free Two Way Radios

Licence Free Radios

Licence Free Two Way Radios - PMR446 (Personal Mobile Radio, 446 MHz) is a radio frequency part of the UHF range that is open without licensing for personal usage in most countries of the European Union. Depending on surrounding terrain range can vary from a few hundred meters (in a city) to a few kilometers (flat countryside). PMR446 is primarily used in consumer-grade walkie-talkies similar to those used for FRS/GMRS in the United States and Canada.

The range of Licence Free Radios is dependent on many factors like environment (in city range is far less than in open field), your height above surrounding obstructions and to a very much lesser extent weather conditions. The antenna type and location, transmit power and receive sensitivity also affect range. However with Licence Free Radios most of these variables are fixed at manufacturing to comply with the PMR446 specifications.

In one of the most significant technology advances in two-way radios in years, Motorola have recently unveiled Europe's first digital licensed free two-way radios, the Motorola DTR2430(TM) and the Motorola DTR2450(TM). The new additions to Motorola's portfolio take the entry level business two-way radio communications to a new level offering cellular-like features, combined with the ability to make both one-to-one and one-to-many calls, without the commitment of monthly fees or contracts.

The new digital license free radios are designed for use on-site and the new features help to expand the capabilities of both individuals and teams enabling them to improve efficiency and productivity through improved communication with functionality such as SMS and Call Forwarding. Other features, such as the Transmit ID, mean radios receiving calls will display the ID of the transmitting unit so people know instantly who needs to get hold of them.

The new digital radios give superior in-building coverage, in comparison with analogue radios.

Text messaging, with ten preset messages that users can change to suit their individual business needs.

Digital One-to-one Calling

is allowing someone to call and talk privately with a user's specific two way radio

Digital One-to-many Calling

Enabling public group calls, meaning all other DTR Series(TM) radios on the same group ID and channel hear communications, similar to analogue radio operation, and private group calls, meaning the DTR Series(TM) radios can be programmed to communicate with specific sets or group members.

Designed for use in the many business environments where communication is the key to helping provide the best customer service, improving productivity or maintaining the safety of workers, the DTR Series(TM) offers a powerful set of innovative and useful features.

Industries such as, education, retail, manufacturing, property management, hospitality and construction could all benefit from the digital performance of the Motorola DTR2430(TM) and DTR2450(TM).

The two way radios also feature enhanced security, with the addition of Frequency Hopping Spread Spectrum (FHSS). The radios are also robust and meet US Military 810 C, D, E and F specifications and Motorola standards for durability and reliability. Users can rest-assured that the radios have been rigorously tested and will combat blowing rain, salt fog, blowing dust, constant vibration, shock and high and low temperature storage.

The primary function of virtually all two way radio systems is to communicate with people on the move. The two main reasons people do this are for economic reasons and for safety reasons.

Economic reasons include ways in which two-way radios can be used to:

Cut operational and business costs

Increase profitability

Improve customer service

Gain a competitive edge

Safety reasons for using two-way radios include:

Quickly response to emergency situations

Keep in touch with people in potentially dangerous situations

Provide backup support when needed

The common denominator to both economic and safety reasons is that radio users have improved control over the resources they manage.

Two-way radio equipment can be classified as either fixed, mobile, or portable.

Fixed equipment is located at a central site such as an office or a headquarters, and usually consists of a base station, microphone, and an antenna. Fixed stations can have three types of control—local, extended local, and remote.

A local control base station is used when the dispatcher’s position is close to the antenna site.

An extended local control base station is used when the dispatch point is up to 1000 feet from the antenna site. The transmitter and receiver are located near the antenna site. The radio’s controls are in a separate unit at the dispatcher’s position, and connected to the radio equipment using a wire line cable.

A remote control base station is used when the antenna site is located more than 1000 feet from the dispatch position. Leased telephone lines may be used to connect the radio equipment with the dispatcher’s control unit.

A mobile unit is a radio that is mounted in either the trunk or under the dash of a vehicle. A portable unit is a battery-powered radio that is small enough to be carried by a person.
