Digital radio is the latest radio technology, which refers to the use of digital technology to transmit or receive across the radio spectrum, while analog radio is the traditional type of radio, using frequency modulation (FM) to encode a voice signal within a carrier wave.

Long range walkie-talkies and two-way radios have a large coverage and can help you communicate and coordinate effectively with others over a long range. What Determines the Range of Walkie-talkies/Two-way Radios? A typical narrowband walkie-talkie has a range of 5 miles, with a maximum range of 36 miles. But it varies due to different obstacles in the surrounding environment. Obstacles will weaken the walkie-talkie signal or even block the transmission signal, affecting the coverage of the long range walkie-talkies and two-way radios. In suburban areas, weather, altitude, terrain, etc. all make it difficult to estimate intercom calls within a given area. In cities, buildings and crowds can severely block your signal, reflect radio waves, and have unpredictable intercom ranges.

What is an ATEX Radio Introduced for the first time in 2003, ATEX certification is an EU standard (Appareils destinés à être utilisés en ATmosphères EXplosibles) designed to ensure that electrical equipment, including radios and accessories, does not provide a source of ignition, such as a spark that might cause an explosion. ATEX radios can meet the strictest safety standards in the world, providing stable, reliable communication in the harshest environments with explosives while maintaining the highest level of safety.

It's time to embrace digital transformation in physical security Why Do We Use Two-way Radios in Security? Security staff relies heavily on what they are equipped with to do their job, like daily routine patrol and security checks, and crowd management on event days. They need to make sure the safety of personnel, clients and property, coordinate staff in emergencies, and get effective communication. Two-way radios are widely accepted as a standard workday EDC (Everyday Carry) tool for security staff, particularly for stadium security, campus security, private security, etc.

Built to Last, Designed for Productivity Why Two-way Radio on Commercial Construction Site Radios are an important communication tool for people in the construction industry, allowing them to communicate with each other instantly, which not only helps to save time and increase productivity but also improves workplace safety.

Every Second Counts, You Can Rely On It Why does the Fire Department Need a Radio? There is no denying the importance of communication in an emergency. Firefighters and commanders at the scene of the fire sometimes have no visual contact, and all communication needs to be made through voice. When lives are at stake and every second counts, a reliable radio can help mitigate damage from fire by enabling crews to work together.

Keeping Teams Connected at All Times The Critical Role of Two-Way Radios in Emergency In an emergency, maintaining critical communications is more important than ever. But mobile phone networks are not always reliable, especially when someone has an accident in a remote area, where network coverage may be imperfect or non-existent.

There are four types of two way radios: portable, mobile, desktop base station, and repeater. * Mobile radios are used in a car or truck and they use the vehicle's power. They will achieve better range by using an externally mounted antenna on the vehicle.

Hytera TETRA, or Terrestrial Trunked Radio is a professional mobile communication system based on time-division multiple access (TDMA) technology, which is designed and developed by ETSI (European Telecommunications Standards Institute).
