What does PCS mean? I've been going through a lot of work and expense trying to improve my cellphone reception in the rual area I live in. There is not a Sprint tower for quite a distance from here. I bought a cellphone booster kit like the one sold out of Best Buy, and after a lot of work erecting a extremely tall antenna mast and running 120 feet of low loss cable I have an improved signal, the only part of the original kit that is still being used is just the booster, I've had to change both antenna's and the cable, but I still need a better signal, so I found an industrial type booster used for office buildings and wharehouses on ebay, I got it for about $300.00 less than it sells for new, I was thinking this should send the signal through the roof, I hooked it up and I got nothing. So I did something I should have done from the start, I researched it. It's for an In-Building Wireless PCS SmartTech Amplifier (60-dB). It's 1850-1990 MHz, so it should work for Sprint. The only thing I can't seem to find any info on is what PCS stands for. I see it everywere, but what does it mean?
