great
Not really. The signal loss is not outrageously severe compared to HTC's
Nexus One. 24db vs 17db.
What makes this problem appears shocking is iPhone's signal bar covers only
23db with the last 4 bars. So if you had only 4bar or barely 5 bar to begin
with, you will see the dramatic effect of bars disappearing one by one.
Even if they had the similar level of signal loss as HTC's phone, you'll
still see a loss of at least 2-3 bars.

they must have deemed it an acceptable compromise when the antenna design
offers much better signal clarity when the signal strength is not reduced
below connection threshold.
In fact, had they changed how the signal bar is calculated before releasing
the product, nobody would have noticed anything but much clearer calls and
better range than anything that came before.

difference
7db at the low end isn't significant in the big picture. probably just
means a mile or two less from the tower. plus, iPhone's much longer antenna
compensate for the lower signal strength

improvement in system performance.

本质上来说，ipad的成功是因为用手指取代鼠标和键盘，这绝不是一个简单的改变。

发帖数: 48 | 32 do you know the typical cell size in urban area? a mile or two. So "a
mile or two less from the tower" moves you from cell edge to right in
front of the tower. 7dB difference is 7dB different, there is no such
saying as lower end or high end, as a matter of fact, at the high end, 7
db less might be ok, for example, drop from 100 dB to 93dB is not a big
deal. (numbers are exaggerated but you get the idea).
