Apple Testing LTE in iOS 5

Last week, Boy Genius Report reported that Apple has been testing a 4G LTE-enabled iPhone with carries, and suggested that an “internal iOS test build” was being used for testing. The build was a property list file (.plist) for LTE. BGR says that this is the file Apple was already using to test LTE hardware in the field. LTE is a new type of wireless broadband network that is currently being deployed by Verizon and AT&T. If the next iPhone is 4G LTE compatible, data speeds will be significantly faster.

MacRumors has discovered that the same LTE plist file in the last couple of iOS 5 builds. The LTE.plist file was only found in some of the builds (GSM iPhone 4, CDMA iPad), and it was related to Apple’s internal “Fieldtest” application.

In addition, Engadget posted a photo from a source who claimed that AT&T had installed 4G LTE equipment in a major Apple retail store. Forbes also pointed out that Apple has put out a job listing for field test engineers with specializing in LTE.

Field testing in the wireless industry typically means going outside (into the field) with a new cellphone and measuring its signal strength. It is an integral step that phone makers must take before releasing products to the public.

Rumors from Verizon and China Mobile executives have suggested that Apple is planning on offering an LTE iPhone at some point.
