Investigation of the influence of the collision domain on the efficiency of the wireless communication

The data channel in the wireless network is essentially a collision domain of the 802.11 standard. In networks with a very high density of VHD subscribers, one of the best strategies to increase the total airtime is to achieve spatial reuse. Spatial reuse of a radio frequency resource is extremely difficult to achieve in practice in very high density zones due co-channel interference CCI and adjacent-channel interference ACI. To understand how to mitigate the effects of interference, the mechanisms by which they impair system performance should be explored. The investigation shows that there is a significant impact on reducing the performance of high-density wireless networks due to suboptimal radio frequency resource planning, which leads to an increase in the impact of co-channel interference CCI and adjacent-channel interference ACI as the number of subscribers increases. The transmissions rate can be reduced by increasing the number of clients to 100. At the same time, there is the potential to increase the performance of a high-density VHD wireless network through good frequency resource design and best configuration practices combined with cell size reduction to limit co-channel interference CCI and adjacent-channel interference ACI.
