Sepura Tier III Systems
True network scalability allows quick and easy deployment of digital systems ranging from just two repeaters on a single site to a national network of over 1,000 sites.
Combining class leading terminals, repeaters, controllers with PC network management software, Sepura DMR Tier III trunking systems deliver a best-in-class solution. Available as an upgrade to existing Sepura Tier II conventional deployments, Sepura Tier III infrastructure is designed to be easy to deploy and operate, while providing powerful functionality and maximum reliability.
A Tier III Controller supports a control (data) channel, individual, group, broadcast and all call voice communication on two way radios, as well as data messaging. Fully digital throughout the Tier III radio network, both control and speech paths between all nodes use low bandwidth IP.
Multiple Controllers on a single site are identical in capability. One Controller acts as a master and maintains a registration database for all of the terminals registered on a site. Any other connected Controllers mirror this database and are always ready to seamlessly switch into the master role if the master was to fail for any reason.
Sepura DMR Tier III trunking systems are fully compliant to ETSI standard TS 102 361-1/2/3/4 and offer high call traffic density in radio systems sharing a limited number of channels.
