Just about every cell phone in current production has the antenna located at the bottom. This insures that the radiating portion of the antenna is furthest from the head. Apple was not the first to locate the antenna on the bottom, and certainly won’t be the last. The problem is that humans have their hands below their ears, so the most natural position for the hand is covering the antenna. This can’t be a good design decision, can it? How can we be stuck with this conundrum? It’s the FCC’s fault.
You see, when the FCC tests are run, the head is required to be in the vicinity of the phone. But, the hand is not!! And the FCC’s tests are not the only tests that must be passed by a candidate product. AT&T has their own requirements for devices put on their network, and antenna efficiency is one of them. I know because I have designed quad-band GSM antennas for the AT&T network. The AT&T test similarly does not require the hand to be on the phone.

Fallout MMO Now Accepting Beta Sign-Ups
Fallout MMO Now Accepting Beta Sign-Ups
After a long gestation period – and its fair share of legal woes – the Fallout massively multiplayer online game is now accepting sign-ups for beta testers. You want in?
Then head to the site below, where you’ll be treated to a suitably-themed introduction sequence showing a few of the game’s locations and characters/enemies.
I can’t imagine post-apocalyptic wastelands are the most enjoyable places the hang out in your spare time and socialise with people. Then again, Fallout is about as fun and cheery as a nuclear wasteland gets this side of Full Throttle.
