Faulty chips behind poor 3G iPhone reception?

And let the finger pointing begin. Apple points to the chip maker and the chip maker points to Apple’s firmware. So who’s to blame? It’s certainly a possibility that some of the chips are faulty but not all of them and it’s possible that the firmware is partly to blame as well. Let’s not forget the network provider as well. Most 3G networks have just recently been implemented I’m sure there’s plenty of bugs to work out.

Richard Windsor of Nomura published a research note (spotted at GigaOm) Tuesday singling out the iPhone 3G’s chipset, made by Infineon, as the probable culprit for the reception problems we reported on Monday. The dropped calls, service interruptions, and abrupt network switches experienced by iPhone 3G users reminded Windsor of similar complaints five years ago, when 3G phones were first launched in Europe.

“We believe that these issues are typical of an immature chipset and radio protocol stack where we are almost certain that Infineon is the 3G supplier,” Windsor wrote. “This is not surprising as the Infineon 3G chipset solution has never really been tested in the hands of users. Some people will not experience these problems as it is only in areas where the radio signal weakens that the immaturity of the stack really shows.” (link)
