Part 1: Site Survey and Overview of DECT Systems18Function of RepeatersA Repeater can be considered as a DECT unit, comprising a DECT handset and aBase Station in one unit that can handle up to three traffic channels. The Repeaterhas the same coverage as a normal Base Station.A Repeater must be placed within the coverage area of the existing Base Stationand, therefore, extends the coverage of the Base Station by 50% (Figure 1.5).When there is active traffic on the Repeater, it takes traffic channels from the BaseStation. Thus, the total number of traffic channels is neither increased nor reducedwith the Repeater.When an active handset moves from Area 1 to Area 2 (Figure 1.5), the Repeatertakes over the active traffic channel and the handset can move around within Area 2(within the coverage of the Repeater); however, as “seen” from the Base Station theRepeater is now the active handset. When the active handset moves back to Area 1and outside the coverage of the Repeater, the Repeater lets go of the active channel,gives it back to the Base Station and there is a full handover between the Repeaterand the Base Station.Repeater50% overlap50% increased coverage ofthe base stationBase Stationconnected to the CCFPArea 2Two Traffic ChannelsArea 1Four Traffic ChannelsFigure 1.5
