Due to the construction materials of an office building, cell phone reception is poor, and it's quite common that calls are dropped.

AT&T, Verizon, and RIM are the typical cell phone networks used (iPhones, Androids, and Blackberries).

Is there a way to boost the signal somehow to provide a better signal? Would I have to attach something to the ethernet network? (there is limited bandwidth, so I would like to avoid this)

You will need a GSM repeater. – Mircea Vutcovici May 1 '12 at 19:52
Why was this closed? It deals with infrastructure. I did some more digging, and found a similar question that was still open:… – Force Flow May 2 '12 at 13:30
Yep, the closing is ridiculous. – gparent May 3 '12 at 14:14
@ForceFlow, for what it's worth, that question was asked back in 2010 - the ServerFault scope has changed a bit since then so a question allowed back then may not be on-topic now. – tombull89 May 3 '12 at 14:19

You'll need to use either a local GSM/CDMA repeater or enable some sort of service (such as UMA) that can tunnel the connection back to the wireless provider over WiFi instead of cellular.
