What is derived from measuring the RF duty cycle?
Answer : C
Explanation:
When planning for VoWLAN applications, what must the overlap be between the cells?
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.
