When using the WLAN planning tool, for areas that have coverage field strength requirements but do not have access to the number of people and bandwidth requirements, which type of area description should be used?
When using the WLAN planning tool, for areas that have coverage field strength requirements but do not have access to the number of people and bandwidth requirements, which type of area description should be used?A . Key coverage areasB . Normal coverage areaC . Dead zoneD . AP deployment areaView AnswerAnswer: B
Calculation formula of signal field strength (without considering factors such as interference and line loss) is:
Calculation formula of signal field strength (without considering factors such as interference and line loss) is:A . Final signal field strength = antenna gain - transmission distance attenuation value - obstacle signal attenuationB . Final signal field strength = AP transmit power + antenna gain - transmission distance attenuation value - obstacle signal attenuationC . Final signal field strength = AP transmit power - transmission distance attenuation value - obstacle...
