The digital repeater RD985 is the heart for multi-cell conventional DMR radio networks and was developed according to the ETSI standard for DMR. It offers an ergonomic design, reliability and outstanding digital functions for sophisticated communication. RD985 – Your digital advantage over your competitors!
Improved utilization of the frequency spectrum
Thanks to the TDMA technology, twice as many users can use the same channel, such as is the case with analog or digital FDMA systems. Due to the restricted frequency resources, this represents an important relief and reduces the expenses for system terminals and licenses.
To protect your radio communications against eavesdropping, the RD985 repeater possesses advanced digital encryption functions, according to the DMRA specification. Depending on the variant, the RD985 supports 40-, 128- or 256-bit encryption. With air interface encryption signaling and communications data between radio and repeaters are transmitted with reliable protection.
High transmitting power
The repeater offers an adjustable transmitting power of up to 50?Watt and thereby satisfies the high requirements for modern PMR radio systems.
Since the repeater was designed according to military standards, it offers high reliability and excellent performance. Test results from independent laboratories have shown that the repeater can be operated for up to 100,000 hours without interference (MTBF) and it therefore meets the requirements for use in extreme situations.
