Can You Run an Open GSM Network? 51
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 (Score:5, Informative)
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)

I'm not sure how much you expect cellphone service to cost; but $20-30/month (note each plan has a system access fee of about $8) is pretty reasonable, and many offer free or cheap phones.

As someone who just today cancelled his Fido service after having ported his Fido number to a Vonage Virtual number (attached to my existing Vonage service), let's look at my typical Fido bill for that $25/month plan:
So, just to get barely reasonable service, which doesn't work in either my home or my office building inside a major Canadian city, costs me more than $50/mo for that "$25/mo" plan. Even if I get rid of the GPRS service and the voice mail and call display, I'm still paying nearly $40/mo for a "$25/mo" plan.
The other poster is correct -- Canada is in the dark ages where cells service is concerned. I signed up for this plan two and a half years ago, and in all that time the infrastructure has been ageing, service hasn't improved, and the price has stayed constant (with the only "savings" being when the Federal Government dropped the GST by 1%!).
(Oh, Fido did get their network coverage "expanded" when Rogers bought them out, but now you have to sign up for YET ANOTHER $5/MO FEE to get "expanded network access").
And none of this includes all the "roaming charges" and relatively high long distance charges.
It doesn't help that the only two GSM providers in Canada are both owned by the same company. The other two main providers (Bell and Telus) are still using CDMA technology, so if you're a cell user in Canada who wants to keep their phone and switch providers, if you're using a GSM phone you're screwed, and if you're using a CDMA phone you have ONE choice. And most of the really interesting, innovative phones are simply unavailable. GPRS is the best network access you can get in most places in Canada -- 3G service is barely even on the roadmap, and is excessively expensive.
I want WiFi/VoIP phone service to eat the call companies breakfast, lunch, and dinner. Competition here is virtually non-existent, and none of the providers is doing much to lower service prices. That's certainly their prerogative , but this consumer has now voted with his dollars. Worse service for more money -- what's not to hate here?

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.

The idea was completely killed by the explosion of GSM cellphones. Smaller, nicer terminals with complete roaming and interoperability no matter where in Europe (and actually, large parts of Asia and Africa) you are. And not so expensive, if you look into it.
