Treo 650 Dial-Up Networking (Sprint)
June 21, 2005
Now that we’ve got the tasty goodness of the 1.12 firmware update for the Sprint Treo 650 out, and Dial-Up Networking is actually enabled in the phone without hacking anything, Make Magazine has a great little write-up on how to use it to hook up your bluetooth-enabled notebook (or desktop even) to the ‘net via your Treo 650.
There was much debate as to why DUN was left out of the initial Treo 650 launch. Many believe it was to keep users from connecting PCÃ¢â‚¬â„¢s to the Sprint CDMA 1xRTT (1 channel Radio Transmission Technology) data network so that their add-on services like picture mail and Ã¢â‚¬Å“expiring ring toneÃ¢â‚¬Â downloads would be speedy. There is still much debate about regular use of a phone as a modem on the Sprint Users forum about what is acceptable. I have been using a voice phone connected to a computer for three years Ã¢â‚¬â€œ starting with an LG 5350 and a USB cable, then a Sony/Ericsson T608 with Bluetooth before moving to the Treo 600 and finally the 650. I have not been charged for any extra data fees on top of my Ã¢â‚¬Å“unlimited VisionÃ¢â‚¬Â account, but I have not had excessive use. I use the phone as a modem only when I have no WiFi access available. The reason for this Ã¢â‚¬Å“carrier fearÃ¢â‚¬Â is due to CDMA using a 13k CODEC with 14k of bandwidth for voice and a data call using 144k of bandwidth without overhead. If you want to read more about the CDMA network, excerpts from a former Qualcomm engineer, Stephen Den Beste can be found here.
With that being said, donÃ¢â‚¬â„¢t abuse the network without expecting extra fees. Now for the good stuff. If you own a Treo 650, this guide will help you with setting up your PC for DUN after you have performed the 1.12 firmware upgrade. You will need a laptop with integrated Bluetooth, or an adapter like my favorite tiny Kensington USB Adapter model number 33085.
This looks pretty straightforward, but unfortunately it’s Windows-oriented. I could probably puzzle it out, but I’ll wait for someone to come out with an updated writeup covering Tiger and the 1.12 firmware..
