iPhone 3G problems occurred in volume production

We reported yesterday about the Apple iPhone 3G-reception problem being blamed on an Infineon chip, although Claes Beckman has another view.

The professor of microwave technology at the University of Gälve believes poor signal sensitivity is the route of iPhone 3G problems. Swedish tech site, Ny Teknik was informed about this study made by the professor.

The measurements show that iPhones sensitivity to 3G networks signals – “nominal sensitivity” – is well below the value specified in the 3G standard, which in Europe defined by the organization ETSI. The result is that it easier than other mobiles to lose contact with the 3G network, and a lower data rates once connected.

Since this value is one of the most important when you check that your mobile phone meets ETSI requirements – a prerequisite for the CE mark – it’s impossible to have been wrong in the first ready-made sheets. The error must have occurred in volume production.

While these findings have not been confirmed in the United States, if they were, it would not be good news for iPhone 3G owners.
