Where Are Stoneham's Cell Phone Dead Zones?

Let us know what parts of town have the worst cell phone reception by posting a comment below.

No matter how high-end the iPhone 5 or other cell phones may be, there are still dead zones. With that in mind, we'd like to know: Where are Stoneham's cell phone dead zones?

Which cell phone network do you have, and where in Stoneham do you typically lose service? Let us know what street(s) or area of town have poor cell reception by posting a comment in the comments section below.

We'll compile a recap story for next week.

Prove it. Where are the years of research. Would you put one in your backyard? I turn my cell phone off at home unless it is truly necessary to have it on. Not an Internet war, just my opinion.

Jared, I don't like proving things, I like giving supporting evidence. I found some research, but its pay-walled so it would be of little use to post the links here. However, lets do some maths. The battery in my phone claims to be 3.8volts and 1500millamps. So thats ~5.7 watt hours. My phone lasts about 24 hours until the battery gives up the ghost completely. So that's 0.23 watts/hour. Lets be (very) generous and say half of that is radio transmissions. That's 0.11 watts/hour. Watts are a unit of power, and radiative power falls off following the inverse square rule. So, lets assume a point source on the phone antenna, with the antenna being about 1 inch from my body (holster). For simplicity, I'll assume that the interaction surface of the propegating signal is a sphere, so Intensity(Power) = S/(4*pi*r^2). In this case, at 2.54 cm, with a signal (S) of 0.11watts, we divide that by (4 * 3.1415 * 2.54^2). That comes out to be around 81. So 0.11watts divided by 81 is 1.35milliwatts. Continued...

With the phone at one inch away from my body, using worst (and frankly impossible) case numbers, the total power reaching your skin (Ghz radio doesn't penetrate well, thats why your hand can block signal) is less than one order of magnitude higher than cosmic background radiation (usually cited as microwatts). Honestly, the medium voltage transformers plugged into your wall charging your phone probabbly have a higher RF footprint at a lower, more penetrating frequency than your phone. But I don't feel like doing that math right now. Hope that helps.

How close would you want one to your house?
