Licensed two-way radios are communication devices that require a license issued by a regulatory authority to operate on specific frequencies. These radios are used for reliable and secure communication channels. These frequencies are typically assigned for specific purposes like public safety, business operations, transportation, or government services.

Licensed radios help control interference and ensure private, secure and reliable communication. By assigning specific frequencies to license holders, regulators can enforce frequency coordination and prevent unauthorised use that may cause interference.

Licensed radios offer wider coverage compared to unlicensed radios like walkie-talkies or consumer-grade two-way radios. These radios use higher transmit power and advanced technologies to extend their communication range, allowing users to maintain reliable connections over greater distances and are available in digital, analogue, UHF and VHF.

Licensed radios often boast advanced features to meet specific critical communication needs. This may include encryption for secure conversations, more channels for simultaneous communication, integrated data capabilities for text messaging or location tracking (GPS), man-down and lone-worker features and better audio quality for clear and accurate communication.

A base station is a device that is used to communicate with and coordinate multiple two-way radios within a given range. It serves as a central hub for communication, enabling users to transmit and receive messages or voice data.

Base stations provide the necessary infrastructure, including antennas and transceivers, to facilitate communication across a wider area. They typically have higher transmitting power compared to handheld radios, allowing them to cover larger distances. This increased range is especially useful in situations where handheld radios alone may not provide adequate coverage, such as in large industrial facilities, multi-site campuses, construction sites, or expansive outdoor areas. Base stations support multiple communication channels or frequencies.

Many base stations also have repeater capabilities. Repeaters receive signals from handheld radios and retransmit them at a higher power, extending the range of communication.

Base stations are often required by organisations to provide additional control and monitoring. They offer features such as caller ID, selective calling, and emergency alert buttons, allowing for more efficient and targeted communication. The base station operator can also monitor the incoming and outgoing radio traffic for better coordination and management.

Base stations can be integrated with other systems such as fire alarms or auto diallers, enabling seamless communication between different platforms.

Mobile radios provide reliable and efficient communication for teams, organisations, or individuals who require a robust wireless communication solution while on the move.

Mobile two-way radios are typically larger than handheld radios and are designed to be installed in vehicles or mounted on a fixed location. They often have a control head with a display unit for easy access to controls and information.

Offering a wider communication range than handheld radios, mobile radios can transmit and receive signals over several miles, depending on the power output and local terrain. Additionally, there is the possibility of utilizing private or encrypted channels as a means of ensuring secure communication

These radios are often integrated with external accessories like vehicle-mounted microphones or headset systems to enable hands-free communication thereby ensuring safety and convenience while on the move.

Trust in Critico to provide radio solutions that go beyond connectivity, becoming a cornerstone for effective coordination, rapid response, and enhanced operational efficiency.

License-free radios, also known as PMR446 (or Walkie-talkies) radios, are handheld two-way radios that operate on the PMR446 frequency band. PMR446 stands for ‘Private Mobile Radio 446’. This technology is perfect for situations where instant, short-range voice communication is needed.

License-free radios can feature push-to-talk (PTT) functionality, voice activation (VOX) and built-in speakers. Some models may offer additional features like LCD screens, privacy codes, and call alerts.

ATEX-certified radios are intrinsically safe radios that are designed to be used in potentially explosive environments. These radios are built to industry standards and are specifically designed and constructed to prevent the ignition of potentially explosive materials and certified to comply with the ATEX directive that ensures their safety in hazardous atmospheres

ATEX radios are commonly used in industries such as oil and gas, mining, pharmaceutical, and other environments where explosive gases, vapors, or dust may be present.
