DD,

Actually I found it nothing more than very basic data found on the web and misrepresented.

For example, in Europe there are at least 3 companies coming out or already starting to make HiperLAN2 = IEEE 802.11a products at 54 Mbps. Here in teh US there is Adaptive Broadband and Proxim Networks who make high data rate devices. All operate in the less restricted "unlicensed" 5GHz band.

Security. It is far easier to tap an ethernet line and steal data than it is to tap the wireless encrypted medium just now. Top standards use significant encryption which combined with multipath effects and not having been admitted to the AP constellation makes interception very difficult.

the market analysis was way off. Here are three basic areas where the cost is very good:

1. retrofit of older, unwired or poorly wired buildings. In the bay area there are already apt complexes isntalling wireless LAN to each unit, using WLL methods, from fiber at the curb. Cheaper than an infrastructure action.

2. "hot spots" airport terminals, cafe's, RR stations (Euro thing) etc. All will present far better wireless internet access rates than a handset.

3. Home, SOHO markets where even 11Mbps available in IEEE 802.11b HR/DSSS products from 3Com, Cisco, NT etc will do the job more than admirably.

REgarding bandwidth it's trickier because all 10 users will not necessarly be accessing the max personal bandwidth all at once. It's not like the telephone but more bursty in nature.

Just my thoughts, cheers,

jgc
