Re: 4g signal boosting...
I got a dongle that had a little connector on the side then I bought a directional Antenna from maplin with a 2 metre cable that plugged into dongle and then you aimed said antenna in roughly the direction you thought the nearest mast was and hey presto. Signal sort of came and went but was a lot better than nothing.
Will have a look on maplin and see if it still exists.
Also you can search for a 4G router using the phrase 'high gain' these use higher power but are just within the limits of being classed a booster and are therefore legal.
I had one which I believe TP Link made but I could be mistaken on the make.
