Service Class Detector for Wireless Network Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless digital communication networks face challenges in increasing range or bandwidth, particularly when communicating streaming media, as prior solutions either consume excessive power, limit network flexibility, or reduce efficiency.
Innovation Solution
A system and method that includes a service class detector and a frame check sequence checker to disregard error-checking information for streaming media PDUs, allowing a higher bit error rate and increasing bandwidth by avoiding retransmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error-checking information is verified for all PDUs to ensure data reliability, then data accuracy is improved, but network bandwidth is reduced due to retransmissions
Solution Approach 1:
The patent applies different error-checking strategies to different service classes: streaming media PDUs have error-checking disabled to maximize bandwidth, while non-streaming PDUs maintain full error-checking for reliability. This local differentiation resolves the contradiction by optimizing each data type according to its specific requirements.
Solution Approach 2:
The patent segments PDUs into different service classes (streaming media versus non-streaming) and applies different error-checking rules to each segment. This segmentation allows the system to simultaneously achieve high reliability for critical data and high bandwidth for time-sensitive streaming data.
2Length of stationary object
If transmission power is boosted to extend communication range, then range is improved, but power consumption increases and battery life decreases
Solution Approach 1:
The patent changes the error-checking parameter for streaming media PDUs by disabling verification, which allows the system to operate at lower transmission powers while maintaining acceptable performance for time-sensitive data, thereby reducing power consumption.
3Reliability
If error-correcting data is added to each PDU to avoid retransmission, then reliability is improved, but network bandwidth capacity is reduced
Solution Approach 1:
The patent applies error-correcting data selectively based on service class: streaming media PDUs use simple error detection with disabled retransmission to preserve bandwidth, while non-streaming PDUs can use full error-correction mechanisms. This local application resolves the contradiction between reliability and bandwidth capacity.
4Length of stationary object
If receiver sensitivity or noise immunity is improved to extend range, then range is improved, but receiver design becomes more complex and expensive
Solution Approach 1:
The patent changes the operational parameters of the receiver by disabling error-checking for streaming media PDUs, which allows the use of simpler, less expensive receiver designs that would otherwise be insufficient for extended-range communication.

AI summary
A system and method, associated with a receiver, for increasing the range or bandwidth of a wireless digital communication network and a receiver incorporating the system or the method. In one embodiment, the system includes: (1) a service class detector configured to determine a service class of a PDU received by the receiver from the wireless digital communication network and (2) a frame check sequence checker coupled to the service class detector and configured to disregard error-checking information in the PDU when the service class indicates that the PDU is a streaming media PDU.
