AirPort Extreme Base Station set to become twice as 'Extreme'? Several of our dirt-diggers have turned up interesting recon this week about an update to Apple's core wireless networking product. It could come as soon as WWDC in May, and if these reports prove accurate, would consist of two 54Mbps 802.11g wireless channels whereas today's AEBS has but one.
Similar technology has been employed by popular networking equipment manufacturers who have rolled out dual-channel 802.11g Access Points, but Apple intends to offer a leading solution for this market and to quickly dominate it by making good use of that second channel on the client side -- a problem that most Wintel offerings have been slow to tackle.
