How to boost a Wireless signal?

I use a Microcell to boost the wireless signal in a condo we use over the winter. It works very well...

Note this from the FAQ...

The AT&T MicroCell works with any broadband service, except wireless and satellite broadband, as long as it supports the minimum broadband speeds of 1.5Mbps downstream and 256Kbps upstream. It does not replace your existing broadband service.

Visit the 3G Microcell forum under the Phones & Devices section for additional information, help, etc.
