Apple Working On Method Of Reducing iPhone Accessory Wireless Interference
A patent application unveiled yesterday (#20070123207) indicates that Apple is working to help Cingular AT&T Wireless remain the carrier with the "least" dropped calls.
The patent application describes a method of determining whether an attached accessory would interfere with the wireless communication of a handheld device (i.e. an iPhone).
In accordance with an embodiment of the invention, a wireless handheld device includes one or more antennas and a connector configured to couple with one or more external accessories. The handheld device further includes an accessory detector coupled to the connector and configured to detect whether an external accessory coupled to the connector may interfere with wireless communication with the handheld device.
Apple says that the device may alert the user (via audio or visual message), or may try to rectify the situation by tuning the handheld's RF frequency.
