Reply about Signal Boosters
Quick disclaimer, I work for Wilson Electronics, but I saw the tweet about your post.
Two products I'd recommend just based on your comments (though if you want a specific recommendation our tech support can help you--it's free and open between 9 a.m. and 8 p.m. EST: 1-866-294-1660) are either the DeskTop or DT Signal Booster or the DB Pro. The DB Pro is more expensive but has higher gain (meaning it's able to pull in weaker signals) and has a better antenna for picking up cell phone signals.
Hope this helps.
