Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional indoor CBSD equipment face challenges in determining their location without GPS line of sight, leading to difficulties in ensuring geographical separation from other transmitters to avoid interference.

Innovation Solution

A system and method that utilize a self-install process for CBSD equipment, where location information is determined by referencing a subscriber database with billing or service address information, and GPS coordinates are mapped to avoid allocating the same or close frequencies to nearby CBSD equipment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If GPS-based location identification is used for CBSD equipment, then location accuracy is improved, but indoor deployments cannot rely on visibility of GPS satellite signals

Engineering Contradiction:

Improvelocation accuracyVSAvoiddeployment feasibility

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent introduces an intermediary system (network address resolution mechanism) that translates network addresses into location information. Instead of directly using GPS coordinates, the system resolves network addresses to approximate locations, enabling indoor CBSD equipment to obtain location data without direct GPS satellite visibility.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/GPS-based location detection system with a network-based address resolution system. By substituting GPS satellite signal dependency with network address lookup mechanisms, indoor deployments can determine location without line-of-sight to satellites.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If frequency allocation is performed without location information, then channel assignment is simplified, but interference occurs between closely located CBSD equipment

Engineering Contradiction:

Improvechannel allocation complexityVSAvoidinterference

Core Design Contradiction:

Device complexityVSObject-generated harmful factors

Solution Approach 1:

The patent performs preliminary location determination through network address resolution before frequency allocation. By obtaining location information in advance of channel assignment, the system can proactively allocate non-interfering frequencies to closely located CBSD equipment, preventing interference before it occurs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses location information as feedback to the frequency allocation process. The allocated frequencies are based on feedback from location data, ensuring that CBSD equipment in close proximity receive sufficiently different frequency ranges to avoid interference.

Inventive Principle:

Principle #23Feedback

AI summary

A system, method and apparatus for registering a wireless station such as a CBRS transmitter establishes registration parameters including location and channel information for avoiding interference from other wireless stations in close proximity. A network address of the wireless station is employed to identify location information in GPS coordinates by referencing a subscriber database with billing or service address information. Registration proceeds with the mapped GPS address and a frequency or channel subject to little or no interference with nearby wireless station by ensuring sufficient geographic and bandwidth separation.
