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)
