Peter Mackenzie: Many wireless networks are designed using a basic RF specification which defines thresholds and limits based on signal strength. Signal strength may be a useful metric when defining coverage but not capacity.
Accurately measuring signal strength is also difficult due to a lack of properly calibrated adaptors and variations in received signal due to multipath and receiver sensitivity. So why do we still hold signal strength values in such high regard when specifying wireless networks? We don’t like to specify things that we can’t validated and most wireless LAN validation is done by measuring received signal strength values with a site survey tools. So will changing the way we validate wireless networks allow us to change the way we specify them?
