G'day, The earlier test today was on slightly undulating terrain, plus or minus half a metre, which made quite a difference to communication between the units. Pings were lost in a dip at about the 800m mark.
I still felt the need for exercise, so I did another test, on another range, this time a sealed road section 1.3km long with slightly raised ends (2m), and no undulation, so that terrain wasn't as much of a problem. The two laptops communicated fine over 1.3km, with the same 10 Hz ping, also carrying a 44100 Hz audio stream of wind noise in WAV format over SSH. Signal level was -83 dBm, noise level was -89 dBm, bit rate shown by iwconfig was oscillating between 5.5 Mb/s and 11 Mb/s for the unit transmitting the audio stream, and 1 Mb/s to 2 Mb/s for the unit receiving. Are there any transmit power knobs to twiddle? Now I shall have to find a longer road ... and maybe get someone to drive me over the range rather than walk it ... the road goes ever on and on ... met a black snake on the way back, warming itself on the surface, but it wasn't interested in the project. Nor was the wallaby or the rabbits. The flies were interested, though. -- James Cameron mailto:[EMAIL PROTECTED] http://quozl.netrek.org/ _______________________________________________ Devel mailing list [email protected] http://mailman.laptop.org/mailman/listinfo/devel
