The Kenwood DMR range of digital Base Station / Repeaters offer the capability to accommodate more channels or user groups and operate across a longer range or wider area in a cost effective communications infrastructure for single-site/local area applications. They share benefits of digital radio communications in providing increased range, improved sound quality and advanced security capabilities.
Capable of outputting up to 40 W in the 400–MHz range, the TKR-D810 repeater is compatible with the DMR Tier II air interface operating in both digital conventional and FM analogue conventional modes.
Both 12.5 and 25 kHz channels are supported for FM (VHF and UHF)
To further expand coverage, you can employ IP connectivity to link multiple conventional repeaters installed in different sites. Each repeater is equipped with a KTI-5 Network Interface Unit to provide the required Ethernet capability.
AIS (Application Interface Standard) is a voice/data communications protocol recently introduced by the DMR Association. By using the AIS IP Console Interface, it is possible to communicate from the dispatch console installed at a base station (command station), connecting to portable and mobile subscriber units via conventional repeaters linked by IP. A total of ten IP consoles can be registered to a repeater, and up to two IP consoles can communicate simultaneously. For group registration, up to twenty group IDs can be registered simultaneously from an IP console.
