Repeater System —Traditional
Although the range between MDS 9810 radios is typically 10 to15 miles
over average terrain, it is possible to extend the range considerably by
connecting two units together at one site in a “back-to-back” fashion to
form a repeater, as shown in Figure 8. Additional details for repeater
systems are given in Section 4.4 (Page 22).

“Single-Radio” Repeater —Alternative Method
A repeater may also be established using a single MDS x810 Trans-
ceiver. This type of repeater cannot operate in full-duplex mode as with
the traditional repeater described above. However, if a loss in transmis-
sion speed and efficiency can be tolerated, it may be a viable solution in
some systems.
