Having had a few comments with J, it looks like a lot of the issues could be resolved by moving to a linux only solution, SMSC software is relatively available these days and using only linux would probably cut the cost by somewhere around £2k - £5k I suspect, also it could possibly resolve the heating / cooling issues.
Just my thoughts... nice piece of kit though ... wouldn't mind one myself (make it open source and I'll do the mods too :)
Thanks :)
When you roamed your T-Mobile SIM on to the network, were you able to receive calls on it? If so, who is getting the roaming interconnect revenue that you'd pay? I guess that making calls wouldn't cost roaming charges?
I wonder why the software isn't wholly Linux? If it really needs to run some Windows software, why not use WINE or run Windows as the virtual machine? Slightly odd.
It would seem to me that the perfect addition to this would be a satellite phone. OK, you can plug it into a LAN or phone jack - but there aren't many of those in the middle of the jungle.
Finally, "No user serviceable parts"? That sounds like a challenge to me. Get some torx and crack it open!
Ideally, you'd grab a number from someone like AQL.. then you can have Voice+SMS+Fax all on one number, and have it automagically route to wherever you are :) No roaming charges, and all your calls can be routed via VoIP out of the PMN when you're at your home/office - I imagine it'd pay for itself fairly quickly!
Maybe we can all club together and time-share a PMN?

just give the man a medal... dammit.
Of course you will still have to find someone with some spectrum to 'borrow' - but the thought of 'Community owned' GSM is one that really appeals to me - particularly as I live in a rural village in a valley in SW Wiltshire where GSM just does not reach (an the MNOs appear relctant to provide coverage).
The OpenBTS project looks great, but the lack of easy legal testing is obviously holding up its progress.
Radio waves should be free, man.
No they bloody shouldn't! That's VC talk there. Standards, properly co-ordinated and managed, are it, man. This is the RF equilvalent of saying that IP should be free - We don't need that pesky IPv4/ICANN system. Free the Bits!
Proponents of free RF favour the 'Detect and Avoid' mechanism, relying on ultra/fast and sensitive detectors to sense when spectrum is in use by others. Nice idea, but there are fundamental flaws in this logic when operating at the noise floor, as CDMA systems do.
We've seen what 'Free' radio waves delivers - Any Blyk subscribers out there?
Funnily enough, I like call quality. I like 5 9's of reliability. I have no desire to bring the wonderful end-user experience that is WiFi RF "management" to the voice/sms world.
You'll be telling me mesh networks are viable next!
