A network node of a communications network configured to provide Citizen Broadband Radio Service (CBRS) to at least one end user device (EUD) in a coverage area of the network node. The network node comprises: at least one processor; and a memory storing software instructions configured to control at least one processor to perform steps of: detecting interference from at least one aggressor device in the network; and reporting the detected interference to at least one of a Spectrum Access System (SAS) and a co-existence manager (CxM) of the communications network.

Interference detection and avoidance in citizen broadband radio service (CBRS)

There is provided a method in a first network node (e.g. CBSD) for negotiating AAS antenna pattern and for radio planning. The method comprises: determining () one or more cell shaping parameters; sending () the determined cell shaping parameters to a second network node (e.g. SAS or CxM); receiving () an allocation of resources based on the determined cell shaping parameters. Another method is disclosed as well and may comprise: receiving () an envelope of radio frequency power for maximizing a coverage area, from a second network node (e.g. SAS); determining () a beam pattern based on the received envelope; sending () the determined beam pattern to the second node.

Protocols and algorithms for contention-based adaptive modulation networks, typically used in unlicensed bands. A wireless system in which high modulation rate packets are prioritized over low rate packets. The wireless system is configured to process communication signals from plural user portable devices having wireless access points capable of dynamically adjusting access point transmit power on a user-by-user basis to a minimum level required to achieve a target signal-to-noise ratio from each user portable device irrespective of the interference observed on the link is also disclosed. The wireless system is also capable of dynamically adjusting access point transmitter power and receiver sensitivity on a user-by-user basis to a minimum level required to achieve the highest possible modulation rate.

Wireless operation in very high density environments

Described herein are a number of steps, methods and/or solutions that can be applied to greatly improve attenuation control of RF signals in cable plant. The present disclosure is directed to a cable modem auto-attenuation system or any other signal transferring system. The system may be capable of taking a high-power signal from the cable plant's service line, dropping the power value down to a usable level and transmitting the signal to a cable modem while eliminating the need for rigorous manual adjustments that a normal cable modem often requires. In certain embodiments, the system may be integrated into a separate device connected between the modem and the cable company service line and configured to handle upstream and downstream attenuation separately or jointly.

A high performance wireless mesh architecture which has been optimized for mobile end points is described. The mesh architecture is intended for Navy applications, where the wireless mesh network extends between mobile ships and includes ship-to-shore links, but it is equally applicable to other mobile elements on, in, or under land, air, sea, or space.

High performance mobility network with autoconfiguration

A distributed or centralized network backhaul delay system includes a plurality of cellular base transceiver stations. Each cellular base transceiver station includes a network backhaul delay element. The network backhaul delay element is configured to calculate delay information associated with network delays between cell sites. The network backhaul delay element is configured to adjust and shape the relative network delays to minimize network delays between cell sites to enable soft handoff to be performed.

Network delay shaping system and method for backhaul of wireless networks

A system and method is provided for estimating the T1 timing error and clock recovery errors by processing timing information from the associated pseudowire packet stream(s) from which the T1 is derived. The timing errors are presented as MTIE measurements which are used to present alarms for a Network Operation Control centre and are used to accurately alarm error conditions where the regenerated or derived T1 signal does not meet MTIE or clock accuracy errors. This alarm is intended to detect conditions of excessive packet jitter, wander or phase transients which may exist in the data network over which the pseudowire stream is transported. In another aspect, the errors are used to control the regeneration of the T1 clock information.
