We just built a new house, cell reception is fairly good but no internet service available. We bought a MiFi and it is working but would like better reception for it and our cell phones. Thinking about a Wilson Electronics Yagi antenna/amp and a central inside house ceiling mounted thing they have (not quite that informed as you might guess). We have a direct line of sight to a tower (don't know if its Verizon) from our roof. Would setting something up like this help to improve our wireless systems (miFi/phones)?
done right it should help you considerably.
how well a repeater like that works, depends on the quality/availability of signal at receiving antenna.
you might want to do a 'local site survey' first, as explained in http://bit.ly/rssi
by the way, the ceiling mounted dome antenna is nowhere near as powerful as the wilson 301135 panel antenna.
i'd never recommend the dome to anyone.
