Disclaimer: I work for a company which has an appliance which creates a wireless local area network at 2.4 GHz and gateways it to the Internet. There are a lot of solutions at 900 MHz and 2.4GHz out there; the practicalities depend on what you want to do. Generally, at the allowed power levels, it's technically not possible to create a "broadcast" system of much value. Point to point aimed connections, sure; low area "broadcast" (i.e., wireless LAN), sure; but for maybe good and obvious reasons, you can't blanket a city with your favorite 2.4GHz signal. The approach I take with my systems is to place our appliances (or, if you like, access points from, e.g., Proxim, Symbol, Netwave) in the various places I'm likely to be (my office, my home). That way, I have Internet access capability (which is the real reason for a wearable anyway) in 99% of the situations I need it. I imagine that doing a 'hybrid' approach, like some of the phones coming out soon, in which you use wireless local area unless you are out of the wireless local area, in which case you go to cell or satellite, would cover the other (occasionally but not usually) annoying 1%.
