One of our customers reported poor WLAN reception: https://docs.openmoko.org/trac/ticket/2043
Since I'm not even sure if this is actually a bug, I'm posting it here for broader discussion. I can confirm that my Neos see fewer access points than, say, my laptop. But I'm not sure if this difference isn't just a natural consequence of having a much smaller antenna. I really don't know what results to expect. I'll ask our hardware team for an estimate. Meanwhile, here's a comparison of the access points my GTA02 see (they each see four access points while the laptop reports about 20 of them). Test done Saturday mid-afternoon, downtown Buenos Aires, humidity around 50%. Signal levels (dBm) reported by iwconfig: ESSID Neo1 Neo2 Laptop jose -95 -87 -89 Marin -95 -95 -88 xyz -53 -45 -39 ALTAMIRANO --- -95 -92 BaseSR -92 --- -84 CBSHOME --- --- -45 "xyz" is just 1m from the Neos or 50cm from the laptop. Also the Neo that generally reports stronger signals varies by up to 8dB when I move it on my desk. CBSHOME is perhaps the most surprising result, because the laptop claims it's strong enough to be very visible. Of course, the laptop also reports one other at 0dBm (that would be about right if I was using the Arecibo antenna, but I think that's not quite what they meant with [EMAIL PROTECTED] :-) and another one at -98dBm, three dB below the noise floor. The rest of the access points are all reported with very weak signal strengths, so I'm not surprised the Neos don't see them. In this test setup, the Neos are not in a great place to receive anything from the outside. If I move them closer to the window, they also see an access point in a restaurant about 100-120m away. - Werner _______________________________________________ hardware mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/hardware
