A method for delivering a communication signal is disclosed. The method includes receiving, at an optical transceiver, an optical communication and constructing, at a baseband integrated circuit in communication with the optical transceiver, a radio frequency communication (e.g., the intermediate frequency data and control signals) based on the optical communication. The method also includes transmitting the radio frequency communication from a Sommerfeld-Goubau launcher in communication with the baseband integrated circuit as a surface wave along a power line to a strand mount device disposed on the power line. The strand mount device is configured to receive the radio frequency communication and wirelessly transmit the radio frequency communication (e.g., via a wireless link) to a user device.

Multi-beamwidth radio frequency (RF) beamforming optimization in a wireless communications apparatus is disclosed. The wireless communications apparatus includes a signal processing circuit configured to process an RF communications signal for radiation in a set of RF beams optimized to maximize coverage in a wireless communications cell. In examples disclosed herein, the set of RF beams includes a center RF beam and a number of edge RF beams. Specifically, the center RF beam is formed with a wider beamwidth to cover a larger center area of the wireless communications cell and, the edge RF beams are each formed with a narrower beamwidth to improve coverage in an edge area of the wireless communications cell. As a result, it may be possible to maximize coverage in the wireless communications cell with fewer RF beams, thus helping to reduce computational complexity, processing latency, and energy consumption of the wireless communications apparatus.
