As an experienced technician, you are responsible for infrastructure design and global
configuration changes. You are asked to deploy a Voice over Wireless LAN for your company. If
the cells have the same channel, the separation between them should be:
A.
19dbm
B.
10dbm
C.
67dbm
D.
86dbm
Explanation:
The overlap of a channel should not exceed -86 dBm (from the center of the measured cell to the
edge of the neighboring cell of the same channel). This is the value of -67 dBm plus the 19 dBm
for separation. Keeping the separation at 19 dBm between same-channel cells produces a cell
with minimal throughput degradation because of media contention. This helps maintain up to 7
good-quality WIPT calls in a cell.
