Dave has already made a strong case for 802.11a in the enterprise, and I whole-heartedly agree with him. There's also the benefit of now 24 non-overlapping channels in the 5 GHz range. Should make channel planning a snap, even in 4D! Eleven channels were approved by the FCC in the last while that are carved from a 255 MHz swatch from 5.47 to 5.725 GHz.
What makes this all promising is that 802.11n will provide transparent support for the 2.4 GHz or 5 GHz range. Atheros has already said that although their first chip will only support 2.4 GHz, they expect that the next and following will support ISM and UNII ranges (except 900 MHz). I also heard from another columnist that Intel's chips, moving forward, will always support both spectrum ranges. "With the announcement of the 3945ABG, Intel said from here on, all its clients will support both 11a and 11g." The 2915ABG already did that, but the latest chip supports CCXv4.

The question has been raised about support of 802.11a. Even though our new access points support 802.11a it may not necessary make sense to deploy the technology. For those who have adopted 802.11a could you answer the following questions: 1) How much usage of 802.11a do you have vs 802.11b/g? 2) Do you have coverage of 802.11a in all locations where you also have 802.11a or is it provided for specific applications? 3) Has 802.11a generated additional support calls?
