When planning for VoWLAN applications, what must the overlap be between the cells?
A . no overlap
B . 15 to 20 percent
C . 30 to 40 percent
D . 25 to 30 percent
Answer: B
Explanation:
The optimal VoWLAN network requires overlaps of 20 percent (2.4 GHz), and approximately 15 to 20 percent (5 GHz), where a WLAN Data design may use an AP cell overlap of 5 to 10 percent.
