You seem to be trying to contradict your own source. Again I quote, "It's amazing really to experience the difference in sensitivity the iPhone 4 brings compared to the 3GS, and issues from holding the phone aside, reception is absolutely definitely improved. I felt like I was going places no iPhone had ever gone before. There's no doubt in my mind this iPhone gets the best cellular reception yet," Here the author is talking about total channel performance.
If TX power is turned up to full, and the other phones leave it down, yes this is true.
Here you go again using weasel words like 'if', does Apple transmit at the FCC limit all the time? That is trivially easy to determine.
The acid test of course is the performance. And your own source said that the performance is great. Again what point are you trying to make?
It's an educated guess based upon a sum of the data points presented. Do you have data to the contrary?
An educated guess? By you? LOL Isn't that kind of like Military intelligence. I have no data at all. I don't even own a cell phone.
- iPhone 4 reception sensitivity is lower, as measured (see table above, and lots of other documented tests all over the Internet)
And yet you have clearly stated that it is the combination of TX and RX that is what is important and your own source claims that the IPhones performance with RX and TX is stellar. Do you see why I am confused?
some iPhone 4 owners have reported poor battery life, which would be consistent with the way cell-phones operate when having reception issues (TX power is turned up, and new cells are connected, both of which require more power)
Again you kind of make an allegation with a weasel word "some" surely that data is easy to come by. And wouldn't we both expect the cell phone to be transmitting at full power on the periphery of Cell tower range?
Summation: the iPhone 4 may compensate for weak reception by increasing TX power and/or constantly seeking and connecting to slightly better cells. That would be a consistent, educated summation.
Consistent, educated summation? First off transmission cannot compensate for weak reception. You are confusing total performance with a single aspect of the equation. And again you are using weasel words "may".
What is your position, and what is your documentation to substantiate it? Or is that only required of me?
I don't have a position, other than I am curious about how much attenuation is caused by proximity to the antenna and if it is excessive. About evidence, you are the one making the allegations, so yes documentation is only required from you.
I have designed several antenna's for airplanes and I am well aware that everything is a compromise. Your source who actually tested the unit indicated that the reception of the IPhone is fine "best cellular reception yet".
And yet you seem to be trying to disagree with your single source of actual data. Why is that?
And so, we find out you don’t even have a cell phone, and have nothing to counter what I wrote or my estimates other than “nuh uh”.
Buh bye.
