as small or large earshells to suit diff erent users. If the MTH 800 is belt-worn, suitable accessories include remote speaker microphone with a 3·5mm plug, receive-only earpiece for use with the remote speaker microphone, a breeze headset with a boom microphone and in-line push-to-talk for low noise, indoor environments. Also available are a personal hands-free kit and both two-

from a series of antennas which includes two combined GPS/TETRA wideband antennas, one helical and one whip. Vehicle-mounted GPS/TETRA combined antenna


solutions are available, with duplexers, cables and adapters. For the company’s other in-demand terminals, such


as the MTP850S – Motorola’s latest TETRA portable, designed for mission critical users and IP55-rated for use in challenging environments – and the small, body-worn TCR1000 TETRA Covert Radio, end users can expect a similar range of accessories.

Motorola For Motorola’s Dimetra TETRA solution, which is designed to meet the needs of a wide range of diff erent markets, the company off ers what it calls “a comprehensive range of convenient and aff ordable accessories” to accompany its various handsets. From chargers and batteries to carry cases and installation mounting equipment for use with a range of static and vehicle applications, this range has been designed to enable professional users to customize their terminals in ways specifi c and personal to the individual user, and often beyond the opportunities aff orded by the bits and bobs which come with any of the standard terminal packages. As an example of the sort


of ancillaries you can expect to support any Motorola TETRA terminal, those for the MTH 800 TETRA handportable include a series of chargers (travel chargers and multi-handset chargers with docks for charging up to six devices at a time) and charger accessories, 800 or 1500 mAh lithium- ion batteries, and in-vehicle kits with cradles, junction boxes, remote visor microphones, external speakers and associated cabling.

To support its terminals, the company off ers a solid though relatively moderate range of accessories. For the 3000 series, they include ear-hanger earpieces, remote speaker-phones and a GSM-style, in-line hands-free kit. High and standard-capacity batteries are supported by a range of charging solutions, from a personal rapid charger to multi-dock chargers and in-vehicle chargers. A series of enhanced antennas is also available for interchange with the terminals by the end user, and of course carrying case


options are available. A similar range of accessories supports the 8000 series handsets (STP8000,


STP8100, STP8200). For mobile terminals,


accessories range from application interface units, virtual and actual consoles, to antenna

connector. And, of course…
