Key planning concepts

Synchronization

An efficient Companion system depends on the following planning concepts:
• synchronization
• power control
• Base Station and cell relationships
• portable originated call
• system originated call
• hand-off
When the portable transmits, the Base Station receives, and when the Base
Station transmits, the portable receives. In all systems, all portables transmit and
all Base Stations receive at the same time. One millisecond later, all portables
receive and all Base Stations transmit at the same time. This synchronization
allows you to put Base Stations together at a cell center.
Because of synchronization when one portable transmits none of the other
portables 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 radios
receive it because they are transmitting (as shown in figure Figure 40).
