Android - Wifi Scan 802.11-b
I'm doing a WiFi channel scanning application running on android device.
Only channels within 802.11b networks shall be scanned.
Is this possible?

my question will be more; I can send probe request from android device and get the probe response. I develop an android application that measures the channel utilization.

"Only channels within 802.11b networks shall be scanned." - No, this is not possible. 802.11b has the same set of channels as 802.11g and 802.11n (2.4G). There is no way to selectively scan for 802.11b networks only.
That's said, it's possible to scan every APs, then shows only 802.11b APs. How this is done is platform-dependent, but generally scan results (from any platform) should have a protocol field (which indicates 802.11b/g/n/a/ac) together with other fields such as RSSI, Channel, etc. The protocol field can be used to filter all detected APs, then display only APs which are operating in 802.11b mode.
