DMR Tier II solution includes Selex ES base station and Tait’s quad-play terminals; GridLink and BioLink applications also on show

Tait Communications has followed up its DMR Tier III system introduced in 2012 with a Tier II system. The system is the result of a partnership with Selex ES, as it uses the latter’s base station. As well as offering DMR Tier II conventional the base station also provides a simulcast solution.
Chris Cant, product and solution specialist at Tait, explained: ‘The DMR Tier II system is not on release yet. It is due in the middle of next year. We are working on the mandatory Tier II standards and then we’ll look at the optional ones and some possible proprietary standards. One of the reasons we have worked with Selex ES is that the price point for our DMR Tier III solution can be too expensive for most Tier II users.’

Tait also had its quad-play DMR Tait 9300 terminal on show. These can be used for analogue conventional, MPT 1327, DMR Tier II conventional and DMR Tier III trunking - all supported by a single firmware version. As such, the radios offer customers an easy migration path from analogue to digital and from DMR Tier II to III.

Applications

Tait also demonstrated its GridLink radio modem, which will be able to support most commonly used utility protocols, for use on SCADA applications and for distribution automation on smart grids. The modem is designed to sit in remote areas and can be pole mounted or installed in roadside boxes.

GridLink reports information registered by the sensors and transmits it to a SCADA control room application in the utility. It can also receive instructions remotely should it need to be upgraded or execute a command. In terms of connections it supports Serial and Ethernet, while Wi-Fi and Bluetooth are also being looked at.
