Abstract: Disclosed herein is a system comprising a set of wireless communication nodes that are configured to operate as part of a wireless mesh network. Each respective wireless communication node may be directly coupled to at least one other wireless communication node via a respective short-hop wireless link, and at least a first pair of wireless nodes may be both (a) indirectly coupled to one another via a first communication path that comprises one or more intermediary wireless communication nodes and two or more short-hop wireless links and (b) directly coupled to one another via a first long-hop wireless link that provides a second communication path between the first pair of wireless communication nodes having a lesser number of hops than the first communication path. A fiber access point may be directly coupled to a first wireless communication node of the set of wireless communication nodes.

Abstract: Disclosed herein is a wireless mesh network comprised of ultra-high-capacity nodes that are capable of establishing ultra-high-capacity links (e.g., point-to-point or point-to-multipoint bi-directional communication links) using a millimeter wave spectrum, including but not limited to 28 Ghz, 39 Ghz, 37/42 Ghz, 60 Ghz (including V band), or E-band frequencies, as examples. The higher capacity and/or extended range of these ultra-high-capacity nodes/links may be achieved via various advanced signal processing techniques. Further, these ultra-high-capacity nodes/links may be used in conjunction with other types of point-to-point and/or point-to-multipoint links to build a multi-layer wireless mesh network.

Abstract: Disclosed herein is a first wireless communication node comprising a first communication module that includes a first baseband unit configured to handle baseband processing for the first communication module, a first RF unit configured to define a frequency range of radio signals for the first communication module, and a first antenna unit configured to generate a first extremely-narrow beam that facilitates exchange of radio signals with at least one other wireless communication node. The first wireless communication node may also comprise a second communication module that includes a second baseband unit configured to handle baseband processing for the second communication module, a second RF unit configured to define a frequency range of radio signals for the second communication module, and a second antenna unit configured to generate a second extremely-narrow beam that facilitates exchange of radio signals with at least one other wireless communication node.

Abstract: Disclosed herein are improved communication systems and methods for operating in a lightly-licensed, shared frequency spectrum. In one aspect, the disclosed systems and methods may involve a small cell having a coverage area and comprising a radio frequency integrated circuit (RFIC), a switch, an antenna, a power amplifier, and a low noise amplifier (LNA). A receiver RF chain of the small cell may be defined by an interconnection between the antenna, the switch, the LNA, and the RFIC, and a transmitter RF chain of the small cell may be defined by an interconnection between the RFIC, the power amplifier, the switch, and the antenna. In accordance with the present disclosure, the LNA may be configured with at least one parameter that is defined based on an uplink link-budget deficiency associated with a client terminal having a given power class and located at a given location of the coverage area.

Abstract: Disclosed herein is a system comprising a first backhaul node, a second backhaul node, and multiple sites that each comprise a respective node configured to maintain a first communication link with the first backhaul node and a second communication link with the second backhaul node, operate in a first mode in which the respective node engages in communication with the first backhaul node over the first communication link and does not engage in communication with the second backhaul node over the second communication link, detect a triggering event associated with the first communication link, and in response to detecting the triggering event, dynamically switch from operating in the first mode to operating in a second mode in which the respective node engages in communication with the second backhaul node over the second communication link and does not engage in communication with the first backhaul node over the first communication link.
