RE: Operations: where are you going to sit?
I have worked in data centers where cell phones, FM radios, Nextel phones, etc. were banned. The theory was that the radios could somehow interfere with the equipment. This never made much sense to me. Are restrictions such as this common? Anyone have any thoughts on if this is rooted in truth or falacy? It's very hard to work on some type of network problems, where you have to console in, while using someone standing outside a data center as a "talker". - Dan Golding On Wed, 6 Dec 2000, Roeland Meyer wrote: > > Go to RadioShack, buy wireless FM, use it in the data center.
