Never have had problems getting voice or data coverage from my office building.

Poor reception. T-Mobile coverage maps 'claim' to have "GREAT" coverage in this area, but it is extremely spotty, lots of dropped calls and dead zones.

AT&T reception is poor and often drops out as other comments in this area T(ysons tollway Wolftrap) have noted. Beware deals offering "free phones" and cool features on phones for teenagers. It is the longer lasting effects of the service or lack of therein that are important.We will switch providers.

AT&T signal varies from very poor to none.

Poor reception in some sections of Waterford HOA, great reception nearest Oakton High School.

Phone will ring sometimes, but it is never possible to talk.

Put in a SOHO repeater with mixed results. Outside RX measurment showed -104dbm which is too low for any reliable coverage (need at least -95). Verizon was just as bad but I don't know the signal strength. I switched to AT&T to get the iPhone and because AT&T's coverage map showed this area as their "best reception." What a joke!

I live right behind the Tysons Corner Sheraton hotel, which has a big cell antenna array at the top of the hotel tower. I can unscrew the antenna from my phone, and still get five bars, and make perfect calls! I wonder how much radiation is frying my brain right now. That probably explains alot... ... ..

from Chain bridge road all the on Lawyers road no signal.

Dropped calls and terrible voice quality inside the house. Signal is more consistent outside of the house although signal strength seems to vary wildly and unpredictably.
