Palm Finally Announces SD WiFi Card
Estranged42 writes "After years of waiting, Palm announced today that it will release an SD 802.11b card for its Tungsten T3 and Zire 72 handhelds. This comes after years of anticipation and speculation about this card ever happening. It should be arriving sometime in September for $129. I think I'm still looking forward to getting one. The Register and others are carrying the story."
Bzzzzzz...wrong. Methinks you got your As and Bs confused.
The PowerBook (or, more correctly, Apple's AirPort Extreme MiniPCI card) supports 802.11b and 802.11g.
802.11g is backwards compatible with 802.11b (despite what I overheard some idiot salesman say to a customer at Best Buy once). You can use 802.11b cards with 802.11g access points and 802.11g cards with 802.11b access points. I do this al lthe time. Part of the reason this is possible is because 802.11b and 802.11g operate in the 2.4 GHz range. The backwards-compatibility is also built into the 802.11g spec (IIRC).
802.11a, on the other hand, is 54 Mbps (like 802.11g), but operates in the 5 GHz range and is not compatible with 802.11b or 802.11g.
Some manufacturers make combo cards that work with all three protocols. Apple is not one of them.
