Selecting Allowed Bands (Optional)
The wln.band property allows you to select the desired mix of communications modes from the list of 802.11 "a," "b," "c," and "d" standards. On the GA1000, this property falls back to 0- WIFI_PHY_11BG_MIXED as soon as the module type is detected (wln.getmoduletype or wln.boot invoked). The WA2000 allows you to select and keep any value from the range offered by wln.band.
Effects of enabling all bands on the EM2000
On the surface, it may look like it would be better to always keep all bands and modes enabled by leaving wln.band at its default value of 5- WIFI_PHY_11ABGN_MIXED. In practice, this slows the system down — wln.scan, wln.activescan, and wln.associate take significantly longer to execute when all bands are allowed. So, if you know that you will be working exclusively in the 2.4GHz band, set the wln.band property to 0- WIFI_PHY_11BG_MIXED. If you know that you will only be using the 5.0GHz band, set the property to WIFI_PHY_11AN_MIXED, and so on.
