“Apple Inc. seeks to assess cellular link performance in direct path and multi-path environments between base station transmitters and receivers using this spectrum,” reads the application, according to BI. “These assessments will provide engineering data relevant to the operation of devices on wireless carriers’ future 5G networks.”
“These assessments will provide engineering data relevant to the operation of devices on wireless carriers’ future 5G networks,” it continued.
Furthermore, two locations have been determined for the tests: one in Milpitas, California on the Yosemite Drive, and the other on Mariani Avenue, where Apple’s first headquarters used to be located.
The application also specifies the 28 and 39 GHz bands, which were FCC approved for commercial use for 5G application back in 2016.
One clear advantage to be had from millimeter wave or 5G technology is the supposed drop in latency once usage of the technology becomes widespread. Source
