Can You Run an Open GSM Network?

OpenCell asks: "Here in Vancouver, cellphone companies are charging ridiculous amounts for basic cellphone plans. I'm wondering if it's possible to run an open/almost free GSM network on a small college campus. Assuming we could find the hardware and get the rights, is there open source software out there to handle most aspects for something like this?"

Most Likely, no

Aside from the red tape, and all such crap there are a few solutions that will allow you to have a MSC+HLR+BSC+BTS but will not scale well, and since , OpenSS7 is barely usable, if at all, there is no way to scale.

oh, and forget about roaming to your local provider when not in coverage if you do not sign a roaming agreement (highly unlikely).

Grab a phone from nokia or others that dose the wi-fi to gsm trick, use voice over IP to lower costs, deploy a comprehensive wi-fi network in your campus, and you will be better served...

Oh, and by the way, six years of experience in the second (734-02) GSM operator in Venezuela (in the telecomms area, just in case someone was wandering)

Before choosing GSM or any other type of air interface (GSM, CDMA, TDMA, AMPS, DECT, PHS, ad nauseum) you should consider your requirements. If offering telephpony service over a limited area to slow-moving terminals (like pedestrians) is important, WiFi or WiMax or other technologies might offer sufficient capabilities to meet those needs.

GSM and other multiple access (the "MA" in CDMA and TDMA) technologies impose a high cost to provide mobility that must scale from pedestrians to automobiles and trains, etc., moving at 200 kmph and faster. This cost is for hardware and software in HLR, VLR and BTS components and others.

If your requirements do not require high-speed mobility, meaning you target terminals which move at human speeds around a limited geographic area like a campus, investigate limited mobility solutions using unlicensed spectrum such as WiFi and WiMax, and using off-the-shelf and Open Source technologies.

You may have to build from the ground up, but as a university your labor pool should be relatively inexpensive, and hardware, too, should be affordable.

Good luck. Please remember to let the readers of SlashDot know what you choose to implement, and your experience doing so.
