Quasi-Licensed Wireless CPE Registration via Alternative Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spectrum allocation systems, such as the CBRS architecture, lack mechanisms for initial registration and authentication of high-power Consumer Premises Equipment (CPE) devices, which are limited by Category B EIRP limits and cannot initiate registration due to interference and path loss issues, potentially causing interference to incumbent users.
Innovation Solution
A method and apparatus for registering and authenticating high-power CPE devices using an alternative connectivity channel between the CPE and an Element Management System (EMS) that facilitates registration with a Spectrum Access System (SAS) via a Domain Proxy, allowing for registration without direct communication with a base station and enabling operation at power levels exceeding standard limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-power CPE devices operate at power levels exceeding Category B EIRP limits, then signal quality and data throughput are improved, but interference to incumbent users increases
Solution Approach 1:
The patent introduces an alternative connectivity channel as an intermediary path for registration and authentication signaling between high-power CPE devices and the Spectrum Access System. This mediator enables the CPE to register and receive spectrum grants without directly communicating with base stations on the CBRS frequency, thereby allowing high-power operation while preventing harmful interference to incumbent users through indirect signaling paths.
2Ease of operation
If high-power CPE devices initiate direct registration with base stations, then registration process is simplified, but registration fails due to interference and path loss issues
Solution Approach 1:
The patent employs an alternative connectivity channel as a mediator for the registration process. Instead of direct communication between high-power CPE devices and base stations on CBRS frequencies (which fails due to interference and path loss), the system uses this alternative channel to establish reliable signaling paths for registration and authentication, thereby ensuring both ease of operation and registration success.
3Adaptability or versatility
If high-power CPE devices are registered through the CBRS architecture, then spectrum allocation is optimized, but registration cannot be initiated due to EIRP limits
Solution Approach 1:
The patent implements preliminary action by establishing an alternative connectivity channel before the high-power CPE device attempts to register with the CBRS network. This pre-established channel enables the device to communicate registration requests and receive spectrum grants without being constrained by Category B EIRP limits during the critical initial registration phase, thereby facilitating both spectrum allocation optimization and ease of device registration.

AI summary
Apparatus and methods for registering and authenticating a client device with a wireless-enabled network. In one embodiment, the apparatus and methods provide an alternate wireless connectivity link to register an installed high-power fixed wireless apparatus (FWA) or Customer Premises Equipment (CPE) with a managed wireless network infrastructure, such as one utilizing “quasi-licensed” CBRS (Citizens Broadband Radio Service) wireless spectrum or another shared access approach. In one variant, the alternate wireless link comprises a mobile cellular channel established via an application program executing on a mobile device. In another variant, an Internet of Thing Network (IoT) is used for the alternate link. In one implementation, spectrum grants are communicated back the FWA/CPE via the alternate link to enable subsequent CBRS-band high-power operation.
