  • Publication number: 20210259032
    Abstract: A system, apparatus and method for installation of outdoor CPE (Customer Premise Equipment) for CBRS (Citizen Broadband Radio Service) for fixed wireless access is disclosed. The system comprises a database server which stores data comprising eNodeB locations and details, pathloss models and throughput prediction data. A position/orientation sensor and WiFi access point are attached to the CPE during installation. For a specified CPE height and a range of pointing angles, a smartphone app is used in scan mode to obtain KPI and evaluate nearby eNodeBs for performance based on stored parameters and link type, to provide estimated UL/DL throughput data for each eNodeB. After selecting an eNodeB, in network entry mode, a RF link between the CPE and eNodeB is established to request SAS grant. If successful in entering operational mode, actual throughput is measured to ensure the desired performance is attained, and data are reported back to the database.

  • Patent number: 10015788
    Abstract: Systems and methods are disclosed for signaling in a point-to-multi-point (PtMP) fixed wireless backhaul network, in which each Hub serves a plurality of Remote Backhaul Modules (RBM). A Hub serves one RBM in each subframe per carrier in TDMA fashion, comprising transmitting a 1 ms TDD frame comprising one DL subframe and one UL subframe and gaps necessary to switch the radio direction and accommodate round trip delay. DL and UL frames may be allocated to different RBMs, with a single RBM in each DL or UL subframe per carrier per antenna beam. Each Hub keeps an independent context for each of its served RBMs. A DL ranging frame carries general information. A UL ranging frame carries a ranging opportunity. RBMs not scheduled in the current timeslot continue to receive a PHY control channel from the serving Hub, and update their parameters or links for link adaptation.

  • Patent number: 9877325
    Abstract: A system and method for joint scheduling in a dual-carrier fixed wireless backhaul network is disclosed, wherein the primary carrier is a licensed band, and the secondary carrier is a lower cost shared band or an unlicensed band. The network comprises a plurality of Hub modules, each serving a cluster of one or more Remote backhaul modules (RBMs). A special frame structure and a control channel on the primary carrier carries control signalling messages for RBMs assigned to either the primary or secondary carrier. RBMs with a performance metric, such a spectral efficiency, above a threshold are assigned to the primary carrier. Other RBMs are assigned the secondary carrier, and a channel assignment is then performed. A transmission mode is determined based on instantaneous channel conditions, to optimize overall system performance across a network neighborhood and meet RBM quality of service requirements. A centralized server/processing unit co-ordinates dual carrier joint scheduling functions.
