One of the new features of the series is the IP55-certified side connector, which enables a user to connect and disconnect an accessory in less than two seconds. Its 1.8-2W output optimizes network coverage and enhances coverage in buildings. The radio also features two control knobs, one for volume and one for talk groups. This offers a user experience similar to analogue radios, allowing easy migration from analogue to digital communications. At entry-level is the MTP3100, a radio for organisations looking for the benefits of TETRA but which don’t need the advanced communication or data sharing features that require a keypad. User scenarios include security patrols maintaining contact with supervisors or maintenance teams co-ordinating operations across a large industrial or processing installation. The MTP3200, on the other hand, whilst still an entry-level device, is for users working in more mission-critical environments who want a radio for use alongside other data-centric devices for tasks such as database look-ups and information sharing during field operations. Applications include supervision and tracking of fire service personnel during incident response, police officers sharing real-time information from central databases, and oil and gas industry inspection teams conducting operations in hazardous environments with constant high noise levels. With Bluetooth connectivity, this handset is designed to increase the operational flexibility and productivity of the user in the field by offering wirefree accessories and connection to scanners, printers and mobile computing devices, and GPS enables user location to be continually tracked during field operations. The third member of the family is the MTP3500, which has all the above features but also a full keypad for more advanced users to maintain critical communication and collaboration between control and field personnel. Its Radio Messaging Service is ideal for users who want to report their status using the radio, a Call Out function allows operators to send a message out with a guaranteed response, and its full telephony capability enables the radio to act as a telephone for calls in and out of the TETRA network. Hytera and UnimoHytera’s Gary Ji, director TETRA department, told TETRA Today that the company was excited to have launched its PT580 at this year’s TWC in Dubai. With a 1.8” high res colour display, the device is IP56 compliant enabling it to work effectively following exposure to a jet of water, and with a 1W output power it delivers a clear digital experience for the user. With MIL-STD-810F rating, the handset is tough for harsh environment use. A man down alarm is activated when the user is inanimate for a period of time. The PT580H is IP67 compliant and, amongst other features of this feature-rich device, offers 3W of output power (adjustable) to enhance coverage and GPS messaging and positioning which can supplement the man down function to locate users in dangerous situations. Also launched at the Dubai TWC were Unimo’s PT-1500 and UT-1500 terminals. According to Unimo’s project marketing team deputy general manager, Daniel Park, talking to TETRA Today, the PT-1500 offers an IP-54 water and dust resistant handset weighing in at just 235g and exhibiting 18 hours of battery life depending on the usage scenario. It has 16 pre-programmed group channels and optional GPS. Park said that it was the world’s smallest and lightest TETRA terminal so far. Its sister handset, the UT-1500 provides a dual-mode device, which can switch between TETRA and GSM or WCDMA if outside a TETRA coverage area. Waterproof to IP-67 standards, it has built-in Bluetooth as an option, a built-in camera which can take and transmit images over TETRA, GSM or WCDMA networks. It also has an SD-card based voice recording facility, with the whole device weighing just 259g. Cassidian’s TH1nCassidian launched its slimline TH1n TETRA radio in the first half of the year in Dubai, a new class of pocket-sized TETRA radios though retaining a large, bright colour display already typical of previous Cassidian handsets. The company says the new small design could well open up the TETRA market to new sectors, such as social workers and health care personnel and is also suitable for covert use due to its size. The handset’s voice quality has been optimized for clarity and its IP65 rating (protection against high pressure water) as well as dust protection ensures reliable performance in demanding environments. An output power of 1.8W provides extra reach when network coverage is at its limit or when Direct Mode Operation (DMO) is used. The repeater feature in DMO enables teams to build a voice connection between users who might otherwise be out of reach of each other. Even with such a slim profile, the TH1n provides usage times comparable with those of any other TETRA radio on the market, thanks to innovative battery technology.
