Wi-Fi is great at local area networking. Although HotSpots and public coverage areas are growing, Wi-Fi will never be able to serve the wide area networks that some advocates dream about. For one thing it has limited range - it was designed for limited range local area networking. OK, there will be improvements that will increase the range to almost double what it is now but that will be with the use of higher power devices (200 mw) that won't be very practical for use in PDAs and laptops. Power management will help but not enough. The other problem is that the channel allocation and addressing scheme of 802.11 is very limited. CDMA used in 1x 3G systems was designed to allow a large number of users. But CDMA cellphone use is low bandwidth so having lots of users was Ok. And with CDMA the noise floor is increased as users increase, causing the cell size to be reduced. CDMA just wasn't designed for broadband data. A lot of people are excited about 802.11b. That is just the start. 802.11g will be a significant improvement and already there is talk about an extended version that would use some of the features planned for IEEE 802.16a/b WirelessMAN to extend the range and make it more robust. But wait a minute, the WirelessMAN standard is intended to solve the range and capacity problems of 802.11. The Wireless Metro Area Networking standard is expected to be ratified by the end of this year. Give it another six months and it will probably make it. With 802.16 there will be several improvements that will make it possible to provide wide area networks that are more easily set up to serve as wide area networks than 802.11 which even hackers have a difficult time stretching into wide area service. All the hype about 802.11 isn't entirely without merit. In fact, 802.11 is a seminal event similar to the use of the first graphics displays in PCs - it helped to create a revolution in the way people used them and that created more revolution/evolution in hardware and software and personal habits. It would be a bitch to be using the Internet on an ASCII screen!
