Abstract: Technologies for wireless network devices with surface-link antenna systems mounted on exterior surfaces of buildings are described. One wireless network device includes a housing with a circuit board and a first antenna port. A processor, a first antenna, a first wireless local area network (WLAN) radio, and a second WLAN radio are disposed on the circuit board. The first WLAN radio communicates with a radio of a client device using the first antenna over a first line-of-sight (LOS) or non-LOS wireless link (e.g., 2.4 GHz) inside the building. The second WLAN radio communicates with a radio of a second wireless network device using the second antenna over a second LOS wireless link (e.g., 5 GHz) that is external to the building. The first antenna is located inside the building and the second antenna is located along an exterior surface of the building.

Abstract: Technologies directed to a wireless network device with a single hardware architecture that supports multiple devices roles through software configuration are described. One wireless network device includes a housing with an RF connector and a circuit board with a first radio coupled to an internal antenna and a second radio coupled to an external antenna via the RF connector. The second antenna is mounted on an exterior surface of the building and coupled to the RF connector via an RF cable. The wireless network device receives a command identifying a device role for the wireless network device and configures itself according to the device role using device setting.

Abstract: Technologies directed to coordinated dynamic analog beamforming are described. One method includes receiving, by a digital controller of a first wireless device, a data packet, the data packet comprising a destination address of a second wireless device. The method further includes retrieving, from memory, beamformer configuration data associated with the destination address, the beamformer configuration data comprising a phase shifter angle value for a radiation pattern. The method sends, to a beamformer circuit, the phase shifter angle value, the beamformer circuit comprises a power splitter and a set of phase shifters (e.g., at least four). The method causes the set of phase shifters to steer the radiation pattern of electromagnetic energy, radiated by an antenna array of elements, at the phase shifter angle value and sends the data packet to the second wireless device via the antenna array.

The second antenna is mounted on an exterior surface of the building and coupled to the RF connector via an RF cable. The wireless network device establishes a first wireless link between the first radio and a radio of a second device via the first antenna and a second wireless link between the second radio and a radio of a third device via the second antenna. The second device can be a second wireless network device that is programmed to operate as a gateway, the gateway being mounted outside of the building. The third device is located inside the building can be either a customer premises equipment (CPE) station or a wireless endpoint device. Each of the wireless network device, the second wireless network device, and the CPE station include identical hardware.

Abstract: Technologies directed to a wireless device with a Radio Frequency (RF) Decibel-Scaled Wireless Interference Detector that provides accurate energy readings of a channel through decibel-scaled output voltage are described. One method of the wireless device includes receiving a first RF signal via an antenna and converting the first RF signal to a multiple samples using a sampling rate, each sample including a digital value of a decibel-scaled output voltage. The method converts each of the samples to an energy value using a voltage-to-energy lookup table and determines a congestion level of a channel using the energy values.
