Apple has filed an application with the FCC to test next-generation 5G technologies. The Commission took steps to enable mobile operations in millimeter wave frequencies and approved the use of the 28 GHz and 39 GHz bands for commercial 5G use last year. Now that the Commission has established service rules for these bands, Apple believes it’s a good time to learn more about what it would take to propagate 5G signals.
The tech developer seeks to “assess cellular link performance in direct path and multipath environments between base station transmitters and receivers using this spectrum,” it tells the agency in an application for an experimental license. The information would provide engineering data relevant to device operation on wireless 5G networks, it says.
Apple intends to transmit from two fixed points at Apple-controlled facilities in Cupertino and Milpitas, CA. The trials “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,” according to Apple. The trials are not expected to go beyond 12 months. Apple intends to coordinate its operations with existing microwave and satellite users in the area to avoid causing them harmful interference.
The filings come as wireless carriers seek more millimeter wave spectrum. For example, Verizon recently agreed to acquire StraightPath for some $3 billion to add to its stable of 28 GHz millimeter wave spectrum plus 39 GHz licenses for the entire country, Inside Towers reported. AT&T acquired FiberTower for more spectrum in the 39 GHz band.
