Use a laptop as a mobile wireless power meter
Just out of curiosity: what router did you use to bridge100 metres? And what is considered to be a sufficient signal strength?
Use a laptop as a mobile wireless power meter
I was using a Belkin F5D8236-4 N wireless router, but not by choice, and I wouldn't recommend it. You can't even set an administrator password on it.
The question of signal strength is interesting. I'd advise you to check it out for yourself using the airport -I command in various places (note that the reported RSSI doesn't respond instantly to a change in signal strength, and the airport signal icon in the menubar is even more delayed). The signal I got at the other end of the shed was about -60 to -70 dBm, which is a signal-to-noise ratio of 20-30 dB, or 100 to 1000.
The signal on the network I'm using right now is at -83 dBm, a signal-to-noise ratio of only 5 dB = 3 (there's about -88 dBm of noise), but I still have full reception according to the airport icon in the menubar. If I go further away from the router, the SNR drops to 0 dB (as much signal as noise), but the airport icon still reports 2 bars. |
