Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current WiFi access points with multiple radios lack flexibility, as radios are not independently configurable and cannot be easily replaced or used with different standards, limiting their operational versatility.
Innovation Solution
A modular wireless network access device with a radio interface that allows up to M detachable radio modules, each with a processor and buffer for independent operation, and an assist engine for managing buffer allocation, enabling flexible configuration and operation with various standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radios are integrated in a single structure or multiple modules, then radio communication capability is improved, but flexibility and ease of replacement are worsened
Solution Approach 1:
The patent divides the wireless network access device into separate functional modules: a controller module containing the processor and switch, and multiple detachable radio modules. Each radio module can be independently configured, removed, or replaced without affecting other radios. The controller module provides a standardized interface that accepts different radio modules, enabling flexible reconfiguration of the system based on different wireless standards or performance requirements.
2Adaptability or versatility
If radios are configured to operate independently, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a controller module as an intermediary between multiple independent radio modules and the data network. The controller module manages the radio modules through standardized interfaces, handling tasks such as radio resource allocation, protocol management, and coordination. This intermediary approach allows radio modules to operate independently while maintaining system-wide coordination, resolving the complexity that would arise from direct peer-to-peer management of multiple independent radios.

AI summary
A wireless network access device comprising a radio interface with a serial communication line, a switch, and M serial connections to M connectors for connecting up to M corresponding detachable radio modules. The radio interface forms up to M individually addressable radio communications paths. Each radio module includes a radio configured to communicate with client devices in a coverage area and a radio processor configured to manage at least one radio receiving buffer. The radio receiving buffers store receiver buffer identifiers to corresponding received data space. A processor manages communication between the client devices that communicate with the radio modules and a data network via the radio interface and a network interface when N≦M radio modules are connected to the radio interface. An assist engine is connected in the serial connection between the processor and the switch to manage allocation of receive buffer identifiers to the radio modules.
