It may be the time of day that I try to connect, i.e. after work. Last night it took 7 attempts to connect via Woosh to check my e-mail. Has anyone else had the same issues?	Marlboro (4607)
208853	2004-01-21 02:58:00	I don't know much about Woosh, but do they install an external antenna or do you use a little stub aerial at your computer like on a PC card wireless modem or wireless network card? One thing wireless advocates have overlooked is the propensity for close-ghosting (yes, just like TV pictures) on UHF signals and this can cause data errors which slow down your connection. If you already have signal ghosting, and the transmitting antenna moves the slightest amount in the wind, you will see even more slow-downs. The integrity of the data is usually protected at the expense of communication speed. All wireless transmissions are subject to various attenuation and distortion effects and only in prime signal locations can you expect reliable and full speed service. Digital cellphones are a perfect illustration of this problem: While analogue phones may go noisy in poor signal areas, they rarely drop the call, but digital spits the dummy as soon as data corruption occurs and the connection is lost. My office has aluminium foil-backed gib board all around and an analogue phone still works fine. However, despite having twice the transmitter power available, digital phone users have to step outside to establish reliable communications. I'll stick to copper wires & Jetstream for now.

The technology is based on W-CDMA - which although sounds similar to Telecoms' 027 offerings, it's a completely different. Woosh (aka Walker Wireless) has teamed up with IPWireless (http://www.ipwireless.com), who make the modems. It looks like you can get PCMCIA Cards to connect too, but not in NZ at this stage. It was great before Christmas, 250 - 280k speed, connecting first time, now it's turned to custard, perhaps due to more customers subscribing...	Marlboro (4607)

I put the following up on the Jetstream thread, but it seems at home here as well . Billy The problem with wireless is that you either need an individual receiver for each on-line user (just as ISPs have rooms full of modems for dial-up and occasionally you can't get a line) or they have to use time division multiplexing (or similar technology) to allow several users to share each receiver channel . The more times you divide the available bandwidth, the slower the individual connections will be . Making more bandwidth available adds lots of $$$$ to their costs so they are not equipped for peak loads, just the average . Sign up plenty of users though, and average load soon becomes peak . The internet bandwidth VS speed equation strikes again . ]:) Cheers Billy 8-{)	Billy T (70)
