Boost GSM mobile signal at home?

I need a way to boost a UK GSM mobile signal for the Orange network.





At home I have reasonable signal in areas of the house, but I would like to have better signal in the house.


This is to facilitate a home automation kit with a mobile card to recieve text message instructions.





TIA

I have seen devices which you attach to a window and you connect your mobile to in order to get a better signal however I have not seen them for sale any where.





No other way to legally boost a signal from your house however I read an article online about a journalist who managed to build his own booster, not legal and very dangerous.





Alternative to stand on your roof, again dangerous





Try some other service providers sim cards in your home, you may be surprised that some networks are better than others in homes due to the locations of the network masks!
