Engineering Contradiction Analysis
1Productivity
If 60 GHz radio frequency band is used for wireless communication, then data communication rate is improved (approximately ten times faster than IEEE 802.11n), but communication range is reduced and system complexity is increased
Solution Approach 1:
The patent introduces relay stations as intermediary nodes between source and destination wireless stations. These relay stations receive signals from the source, process them, and forward them to the destination, enabling extended communication range in the 60 GHz band while maintaining high data rates. The relay mechanism effectively mediates the communication between stations that cannot directly communicate over long distances.
2Productivity
If 60 GHz radio frequency band is used for wireless communication, then data communication rate is improved (approximately ten times faster than IEEE 802.11n), but communication range is reduced
Solution Approach 1:
The patent divides the communication path into multiple segments by introducing relay stations. Instead of requiring a single direct link between source and destination, the communication is segmented into multiple hops: source to relay, and relay to destination. This segmentation allows the system to achieve extended communication range while maintaining the high data rates characteristic of the 60 GHz band in each segment.
3Productivity
If directional line-of-sight transmission is used in 60 GHz band, then data communication rate is improved, but reliability is reduced when direct links are disrupted
Solution Approach 1:
The patent employs relay stations as mediators to establish alternative communication paths when direct line-of-sight links are disrupted. The relay stations can receive signals from the source station and forward them to the destination station, providing redundancy and maintaining communication reliability even when direct links are blocked or disrupted.
