>Apple opting for 802.11g support in next AirPort update
>By Nick dePlume, Publisher and Editor in Chief
>
>June 17, 2002 - According to sources, Apple Computer Inc. has made the 
>internal decision to adopt the IEEE 802.11g wireless networking standard 
>in future versions of its AirPort technology.
>
>What will be absent from AirPort updates is 802.11a, a new protocol which 
>many wireless networking manufacturers are using to supplement 802.11b, 
>the current standard on which AirPort and many other products are based.
>
>The reasoning behind this is largely a technical one. Reportedly, the most 
>important factor is that 802.11g is backwards compatible with 802.11b, 
>since it is in the same 2.4 GHz frequency as AirPort's networking. 
>802.11a, on the other hand, is in the 5 GHz range.
>
>Additionally, Apple has been able to maintain ranges of 175 feet with 
>802.11g, still keeping top speeds. While the speeds of A and G are the 
>same, 802.11a tends to drop from its maximum speed at a about 50 feet. One 
>potential advantage to A is that even though it's incompatible with B, the 
>fact that it is in a different spectrum could mean less RF interference.
>
>Regulatory approval of 802.11g is scheduled for next year, so a release of 
>new AirPort hardware in the short-term is unlikely.
>
>In November, Apple announced the second generation of its AirPort 
>products, unveiling a base station with support for AOL users, 128-bit 
>encryption, and a built-in firewall.
