"I picked this up off the Internet today from TipWorld under the heading "Mobile Computing". Maybe wireless email isn't too far down the road (oops - channel!)" ======================= These systems are not the same as mobile wireless sytems. They are "fixed" cellular systems that actually take advantage of the fact that the network and system "knows" that the "mobile" will never move. They are actually 'scaled down' cellular systems in the sense that there is no logic embedded in either end for maintaining a moving radio link (handoffs, fading, etc.). I don't see these as ever migrating over to boats or any other mobile environment (unless you plan to be somewhere for a LONG time! :-O). They have been optimized for a very specific purpose. Keep an eye on the 3G stuff in cellular and you'll have a better chance. Regards, Ray Henry Tug O War Sundowner 32 - Belhaven, NC --------- 5 out of 4 people have trouble with fractions.......
