The DIB-R5 base station family is a constituent of the TETRA mobile radio system
ACCESSNET-T IP and ensures the powerful and reliable mobile radio coverage of a spe-
cific area. Pioneering TETRA Release 2 support, particularly the TEDS technology
(TETRA Enhanced Data Service), render the DIB-R5 extremely attractive for all scenarios
in which a high degree of availability as well as high-speed data are absolutely neces-
sary. The TEDS data transmission allows transferring up to 150 kbit/s (gross bit rate)
securely and reliably via the air interface.
