We have a few dead spots in our office where we have to stand by the window to get enough bars to recieve and make voice calls.
I bought and installed a 700 MHz 4G LTE antenna and booster amp system. Didn't help.
I'm thinking that maybe I should be boosting the 3G signal, not the 4G, but I'm not sure which frequency to boost 900Mhz or 1900Mhz.
We're in NYC, signal strength is great everywhere except the one or two spots at one end of the office.
Anyone have a suggestion?
TIA
Howie
