Share your personal wireless Internet with friends
CTR-350 Mobile Broadband over Wi-Fi is a router from Cradlepoint. It makes possible for you to share your General Packet Radio Service/Enhanced General Packet Radio Service (GPRS/EDGE) Internet connectivity that you subscribe to, with all your buddies. But it makes more sense when the primary connection is a Wireless Fidelity (Wi-Fi) connection. That way sharing it won't end in lower speeds to the others sharing your connection.
You can invoke the device's security just by pressing down a button. It also has Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) encryption with a built-in firewall. If your phone supports Universal Serial Bus) USB, you can charge it as well, via this device. CTR-350 IS priced at USD 149 (Rs.5,960). However, as of now, there's no confirmation on the availability.
Who would want to slow share a snail paced GPRS over WI-FI,Edge offered by operators does not stand up the claims advertised and is expensive.
And ADSL wifi router is the best bet,ofcourse it lacks mobility
You're uninformed, and your comparison is makes no sense ... mobility is the key feature...plus the cradle point supports 1xEVDO Rev A, which runs up to 3.5Mbps, so it is very sharable (I get on average 1100kb/sec with my Sprint 595U device).
