Yeah I can get cellular radios for various carriers but there's hardly any =
signal at all in the area. The electrician has and Android with ATT and no =
signal at all.  I have Verizon Iphone and I was able to get text message bu=
t calls were spotty. Had to go outside to stay connected. So obviously ther=

t in the middle of the house (this is a takeover ) and this house was built=
 by the owner who is in the transit mix cement and mason business. It's lik=
e a stone fortress. Getting to the out side or to the second floor or attic=
 with a wire, is probably not going to happen. The floor between the first =
floor and basement is made of concrete with radiant heating.=20

Customer wants remote control of alarm system and I've been using cellular =
(Napco Starlink) to do that. =20

I was pretty sure the "Boosters" that the phone companies provided where ju=
