Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The channel capacity of communication apparatuses varies significantly based on their installation environment, leading to decreased efficiency due to signal collisions in urban areas and limited viewing angles in mountainous regions.
Innovation Solution
A communication apparatus that acquires environment information and specifies an optimal transmission scheme using relational data to adapt transmission methods, such as adjusting error correction codes and transmission power based on the installation environment, to improve communication efficiency.

Engineering Contradiction Analysis
1Area of stationary object
If communication apparatuses are installed in urban areas with many competing devices, then coverage area is improved, but channel capacity decreases due to signal collision
Solution Approach 1:
The patent changes transmission parameters (modulation scheme, code rate, transmission power) based on the number of competing communication apparatuses detected in the environment. When many devices are detected, the system selects transmission schemes with lower order modulation and higher error correction to maintain reliable communication despite signal collisions, thus resolving the contradiction between coverage area and channel capacity.
2Adaptability or versatility
If communication apparatuses are installed in mountain areas with obstacles, then installation flexibility is improved, but channel capacity decreases due to narrow viewing angles
Solution Approach 1:
The patent adjusts transmission parameters based on detected environmental obstacles and viewing angle constraints. In mountainous areas with narrow viewing angles, the system selects transmission schemes that are more robust to multipath fading and signal attenuation, such as using diversity modulation schemes or increasing transmission power, thereby maintaining channel capacity despite installation flexibility requirements.
3Reliability
If transmission power is increased to improve channel capacity, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The patent dynamically adjusts transmission power as one of the transmission parameters based on environmental conditions and channel quality. The system increases power only when necessary to maintain reliable communication in poor channel conditions, and reduces power in good conditions, thus resolving the contradiction between channel capacity and energy consumption through adaptive parameter selection.

AI summary
An acquisition unit acquires environment information indicating an installation environment of a communication apparatus. A scheme specifying unit specifies a transmission scheme of data on the basis of relational data indicating a relationship between the environment information and the transmission scheme and the acquired environment information. A transmission unit transmits the data to a relay device on the basis of the specified transmission scheme.
