Insanely fast mobile data speeds could be coming soon to Apple’s iPhone lineup, based on a new filing with the FCC that reveals the company has begun testing 5G network technology.

Apple recently applied for an experimental license to use new wireless technology called “millimeter wave.” The FCC approved Apple’s permit today and revealed some details about the project by making the company’s application public.



“Apple Inc. seeks to assess cellular link performance in direct path and multi-path environments between base station transmitters and receivers using this spectrum,” the company states in its application that was first found by Business Insider. “These assessments will provide engineering data relevant to the operation of devices on wireless carriers’ future 5G networks.”

The Power of 5G

Testing of the new millimeter wave technology will be done at two sites in California. One of the test sites is located on Mariana Avenue where Apple’s first headquarters were located. Other tests will be run in Milpitas, California, on Yosemite Drive.

It’s unknown exactly what Apple is using the tests for. Wireless carriers like Verizon and AT&T have started preparing to roll out 5G technology over the next few years. At peak performance, 5G networks could provide smartphone users with 1Gbps connections. It’s likely that Apple is testing modems that will be used in the iPhone to bring 5G speeds to customers.

The application mentions the 28 and 39GHz bands that were approved for 5G uses by the FCC last year. Tests will use technology created by Rohde & Schwarz, A.H. Systems, and Analog Devices. Apple says it will conduct its experiments for a period lasting no longer than 12 months.
