TETRA is the primary choice for mission-critical communications when both voice and data are required. It has been designed to combine reliability, security and good voice quality with a high level of standardisation and some of the most advanced data capabilities among narrowband technologies. But up till now, TETRA has only been available in UHF, and any users for whom wide radio coverage is a key driver have had to deploy other technologies.
Opening the TETRA market to VHF makes TETRA a viable alternative to DMR and P25 in a variety of challenging operational outdoor environments. A DAMM VHF TETRA Solution extends coverage of TETRA, offering a good choice for medium- to high-capacity trunked networks — now over extended coverage areas. Further, it offers an infrastructure architecture, which previously has not been available for VHF, where the network can be built with outdoor mast-mounted base stations — which should improve service availability and reduce network complexity.
