Apple Preps For iPhone 5G Wireless Testing Near Cupertino HQ
"Apple Inc. seeks to assess cellular link performance in direct path and multipath environments between base station transmitters and receivers using this spectrum," the application states. "These assessments will provide engineering data relevant to the operation of devices on wireless carriers’ future 5G networks."
"These transmissions will be consistent with the parameters and equipment identified in Apple’s accompanying Form 442, and will include the use of a horn antenna with a half-power beamwidth of 20 degrees in the E-plane and H-plane and a downtilt between 20 - 25 degrees. Apple anticipates that it will conduct its experiments for a period not to exceed 12 months," the application continues.
The application makes specific mention of the 28GHz and 39GHz bands, both of which the FCC approved for commercial use for 5G applications. Apple's experiments will use technologies developed by Rohde & Schwarz, A.H. Systems, and Analog Devices.
As to what exactly Apple is hoping to accomplish, that is not clear. The company has only been loosely linked with 5G research, with it having recently joint an industry group for 5G development
