Multi-band OFDM Data Rate Expansion via Stream Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication standards, such as the MBOA Ultra Wide Band standard, are limited to data rates of 480 Mbits/s, which is insufficient for high-speed applications like Ultra High Data Rate transmission above 1 Gbits/s, and existing wired links in computer systems constrain data rate performance.
Innovation Solution
The method involves splitting an initial high-data-rate stream into multiple elementary streams, each transmitted concurrently on different sub-bands within the existing communication standard, using existing MBOA units without modification, allowing for simultaneous transmission and recombination to achieve higher data rates without altering the communication standard or its building blocks.

Engineering Contradiction Analysis
1Productivity
If existing wireless communication standards (MBOA UWB) are used, then compatibility with existing hardware and standards is maintained, but data rate is limited to 480 Mbits/s
Solution Approach 1:
The patent divides the high-rate data stream into multiple elementary data streams, each compliant with the MBOA standard's data rate limit. These elementary streams are then transmitted simultaneously on different sub-bands using existing MBOA units, allowing the system to achieve ultra-high data rates (above 1 Gbit/s) while maintaining full compatibility with the existing MBOA standard and its hardware.
2Productivity
If wired links are used for high data rate transmission, then data rate performance is achieved, but architectural flexibility and reliability are reduced
Solution Approach 1:
The patent replaces the mechanical wired connection with a wireless transmission system. By splitting the data stream into multiple elementary streams that can be transmitted concurrently on different sub-bands, the system achieves wired-like data rate performance (above 1 Gbit/s) through wireless communication, thereby eliminating the physical constraints and improving reliability associated with wired links.
3Productivity
If data stream is split into multiple elementary streams for simultaneous transmission on different sub-bands, then data rate exceeds 480 Mbits/s, but system complexity increases
Solution Approach 1:
The patent segments the high-rate data stream into multiple elementary data streams, each compliant with the MBOA standard's data rate limit. These elementary streams are then transmitted simultaneously on different sub-bands using existing MBOA units, allowing the system to achieve ultra-high data rates (above 1 Gbit/s) while maintaining full compatibility with the existing MBOA standard and its hardware.
Solution Approach 2:
The patent combines multiple parallel transmissions on different sub-bands into a single high-rate data stream. By simultaneously transmitting multiple elementary data streams on different sub-bands and then combining them at the receiver, the system achieves aggregated data rates exceeding 480 Mbits/s while using standard MBOA units without modification.
