Boosting Cell Phone Signals in Strange Places?
hedgemage asks: "I work at a retirement home and we have trouble with the cell phones that our nursing and maintenance staff use. The problem is that our nursing home area is built into a lower level that was originally constructed as a fallout shelter in 1960. There's a lot of solid concrete in the walls and ceiling. We have paid out tens of thousands to try and get an on-site mobile to work using NEC Dterm PSII phones, but they have proven absolutely unreliable (not just in the bomb shelter but throughout the campus) and the only solution our telecom provider has is to install several thousand dollars more in transceivers. If we could use ordinary cell phones, it would be ideal for everyone. Is there an off-the-shelf solution that could boost regular cellular signals in our bomb shelter?"
What, you weren't planning on visiting the facility to which you'll send your mother, first?
You may be making things more complicated than they have to be by insisting on the absolute newest technology. Sometimes an older technology fits the situation better. For instance, if you just run some land lines down there, you can install regular old cordless phones. With the base-stations and the phones both in the sheltered area together, reception should be largely unaffected by the super-thick walls, and Bob is your uncle.
Cut that out, or I will ship you to Norilsk in a box.
