The region has the worst cellphone reception among the top 27 cellular markets, according to a new study by J.D. Power and Associates. In our area, 18 out of every 100 calls is affected by static, echoes, or is dropped altogether, the report found.

The study doesn’t explain why we’re a giant reception-sucking dead zone, but it appears switching carriers won’t make much difference. AT&T, Verizon, T-Mobile and Sprint had virtually the same number of problem calls on average in the Mid-Atlantic region. IPhone and other smartphone users had worst reception on average than callers using lower-tech handsets.

Overall, the study found improvement in call quality has halted. The reasons: More callers are using smartphones and more calls are being made indoors, where reception problems are more likely to occur.
