Chip causing problems in iPhone
An Infineon chip could be at the root of complaints from around the world that Apple Inc’s new iPhone drops calls and has unpredictable Internet links, according to a research report from Nomura.
BusinessWeek also reported on its website on Thursday that the iPhone is suffering from faulty software on an Infineon chip, and that Apple plans to fix the problem with a software update.
Representatives for Apple and Infineon declined comment.
One of the key attractions of the latest iPhone, which went on sale in July and sold 1 million in its first weekend, is faster, third-generation (3G) Web connections when compared to the first iPhone that was launched in mid-2007.
However, users have complained on websites and blogs that Internet speeds have been inconsistent and that the phone often reverts to a slower technology known as Edge even in 3G areas.
Nomura analyst Richard Windsor wrote in a research note that the problem likely involved a 3G cellular network communications chip made by Germany’s Infineon.
“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 in the report dated August 12.
“There are too many instances on iPhone blogs and Apple’s own website for it to be coincidence. Furthermore, it is not just the U.S. but other countries as well,” he wrote
