and Vodafone UK
used Vodafone Egypt as scapegoats with me as to why their billing and website was borked during and after the revolution. Great company, I don't think.
A three-minute video put out by its advertising agency claims that Vodafone Egypt was the driving force behind the revolution, much to the annoyance of the revolutionaries – and Vodafone.

Yes of course the govmnt can shut down any radio based system since all radio licences have a clause stating something along the lines of :
Cease transmitting at the request of the Secretary of State or his duly authorised deputy
So all the cell towers can be turned off at the whim of a politician or civil servant
Femtocells are still routed through the same back-end infrastructure, so in this context would be switched off at the same time as the macro network.
Shame really, and we'll be taking a look at how one might step outside governmental control (as Free Libyania did) in the next few weeks.
Bill.
Of course theUK Government has the power to do this using Access Class blocking! Access Class is built into the design of the networks and SIM cards in terminals to permit locking so that only a certain class of SIM's can use the network.
Joe Public has SIM's with access class 0-9. "Special ones" (and network engineers) have SIM's with access class 10-15. This is typically invoked in emergency situations - after bombs etc. All ordinary users cannot make or receive calls, but those with the special SIMs carry on using it as normal. It could (but I don't think ever is used) be used to reduce congestion - eg: locking only a proportion of SIM's (say 0-4) off the network, but mainatining it for those fortunate enough to have SIM's with an access that has not been locked (ie 5-9).
