Part 3 Planning DECT systems 623
5.3.4 Using repeaters (relays)
Repeaters are autonomous devices equipped with two antennas, which increase
the range of the DECT system. They receive the signals from one radio unit over
one antenna and send the signals back out again over the second antenna. When
positioning a repeater you need to make sure not only that the coverage ranges
overlap but also that the repeater is mounted in the coverage range of one radio
unit and vice versa. Several repeaters can be allocated to one radio unit. Ring-form
(see Fig. 3.23) as well as other arrangements around a radio unit are possible.
Most repeaters operate in "Blind-Slot mode". As they receive and send, only 2 call
connections are possible simultaneously on each repeater.
Cascaded repeaters are not supported. However the handover between individual
coverage ranges is guaranteed.

Even remote buildings can be covered with a repeater by using external antennas
with rectification.
