Ethernet Media Converter Aggregating 1G Streams for High-Speed Wireless
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid advancement in wireless communication standards, such as from 802.11g to 802.11ac, renders existing 1G Ethernet switches obsolete, necessitating costly replacements to support higher data rates, leading to a continuous financial burden on enterprises.
Innovation Solution
A media converter that aggregates multiple 1G Ethernet data streams into a single 2.5G or 4G signal, enabling higher data rate transmission over existing 1G Ethernet switches, thus allowing compatibility with 802.11ac wireless access points without the need for switch replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If 10G operability is implemented to support higher data rates, then data transmission speed is improved, but power consumption increases to unacceptable levels
Solution Approach 1:
The media converter dynamically adapts its operation mode based on the capabilities of connected devices. It can operate in full-duplex mode when both ends support it, or fallback to half-duplex mode when connecting to legacy 1G devices, optimizing power consumption while maintaining necessary data rates
Solution Approach 2:
The device changes its operational parameters including data rate (1G/2.5G/4G/10G), duplex mode (half/full), and power state based on negotiation with connected devices. This allows the system to achieve high data rates only when necessary, reducing overall power consumption
2Adaptability or versatility
If 1G Ethernet switches are replaced with 10G switches to support new communication standards, then compatibility with high-speed wireless access points is improved, but cost increases substantially
Solution Approach 1:
The media converter acts as an intermediary device between legacy 1G Ethernet switches and modern 802.11ac wireless access points. It translates and adapts signals between different standards, allowing old switches to work with new high-speed wireless devices without requiring replacement of the expensive switch infrastructure
Solution Approach 2:
The media converter provides multi-functionality by supporting multiple data rates (1G, 2.5G, 4G, 10G) and multiple duplex modes. A single device can serve both legacy 1G connections and modern high-speed connections, replacing the need for multiple specialized devices and reducing overall system cost
3Quantity of substance
If existing 1G Ethernet infrastructure is used, then cost is reduced, but data transmission rate is insufficient for modern wireless standards
Solution Approach 1:
The media converter adds a new dimension of capability to the existing 1G infrastructure by incorporating higher-speed interfaces (2.5G, 4G, 10G) and advanced features like half-duplex support. This allows the old infrastructure to access new performance levels without complete replacement

AI summary
Disclosed are method and system for Ethernet media conversion supporting high-speed wireless access points. The method includes receiving at each of a plurality of input-side Ethernet modules in a media converter, a plurality of input data streams at a first data rate. In the media converter each of the plurality of input data streams may be aggregated into an output data stream at a second data rate. The output data stream may then be transmitted at the second data rate from an output-side Ethernet module in the media converter. Each of the input data streams may be received from an Ethernet switch, and the output data stream may be transmitted to a wireless access point. In one exemplary implementation, each of the input-side Ethernet modules may include a 1G PHY, while the output-side Ethernet module may include one or both of a 2.5G PHY and a 4G PHY.
