Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-band spectrum (24 GHz band) is used, then transmission speed is improved, but coverage area is reduced
Solution Approach 1:
The patent introduces the 12 GHz band as an intermediary spectrum between low-band and high-band options. This intermediary band provides a balance that combines the coverage advantages of lower frequencies with the speed advantages of higher frequencies, resolving the contradiction between coverage and speed without requiring operators to choose one extreme over the other.
Solution Approach 2:
The patent changes the frequency parameter from conventional 24 GHz high-band to 12 GHz mid-band, which fundamentally alters the propagation characteristics. This parameter change enables signals to travel farther while maintaining adequate bandwidth for high-speed applications, simultaneously improving both coverage and speed performance.
2Area of stationary object
If low-band spectrum is used, then coverage area is improved, but transmission speed is reduced
Solution Approach 1:
The patent changes the frequency parameter from low-band (below 1 GHz) to 12 GHz mid-band. This parameter change maintains the long wavelength and propagation advantages of lower frequencies for extended coverage while providing sufficient bandwidth to deliver high-speed transmission, overcoming the speed limitation of traditional low-band spectrum.
3Quantity of substance
If 24 GHz band is used for 5G deployments, then bandwidth is improved, but coverage is limited to 1 mile or less
Solution Approach 1:
The patent positions the 12 GHz band as an intermediary solution between the bandwidth advantages of 24 GHz high-band and the coverage advantages of lower bands. This intermediary frequency provides adequate bandwidth for 5G applications while enabling coverage extending beyond the 1-mile limitation of 24 GHz, making it suitable for both high-speed performance and extended reach.
4Reliability
If spectrum is allocated to provide both speed and coverage, then network performance is improved, but spectrum resource scarcity is exacerbated
Solution Approach 1:
The patent changes the frequency parameter to 12 GHz, which offers a more efficient use of spectrum resources. This parameter change enables operators to achieve both high network performance and extended coverage without requiring the extensive spectrum allocation that would be necessary if using traditional 24 GHz high-band only, thereby addressing spectrum scarcity while maintaining performance goals.
