In all systems, all portables transmit andall Base Stations receive at the same time. One millisecond later, all portablesreceive and all Base Stations transmit at the same time. This synchronizationallows you to put Base Stations together at a cell center.Because of synchronization when one portable transmits none of the otherportables receive it because they are transmitting (as shown in figure Figure 39),and when one Base Station radio transmits none of the other Base Station radiosreceive it because they are transmitting (as shown in figure Figure 40).
