I open the floor to the above.

Does anyone have any examples of known EMI issues in the datacenter caused by cellphones? Or other radio communication devices?

No the company I work for is thinking of releasing the restriction, however I have some good examples of cellphone interferance issues. I'll post more details when I'm back at a pc. I was just hoping to stimulate some debate.

The most likely source of interference would probably be coupling of the GSM transmit on/off burst from the phone into the operator/customer audio path.

I would have thought that there would also be a management reason for a restriction as they would rather staff were dealing with customers than doing non-work stuff on their mobiles

Engineers may need a means of communications for many reasons - including emergencies. Some organisations decide this is Mobile or site radio (e.g. TETRA).

Depending on the site and its layout, I wouldn't propose a "blanket ban", but one based on risk assessment specific to the organisation (for whatever reason - EMC included).

I've never seen a restriction on cellphones in datacentres, at least, not for interference reasons. Some of the more secure facilities I've visited have restrictions on devices such as Cameraphones, and USB Mass Storage devices. Some Datacentres also allow USB and network-attached 3G and GPRS Modems to be racked, so I suspect that there's no massive evidence for interference.
