This research aims to identify the reality of wireless telecommunications companies and the quality of services they provide to citizens. Scenarios confirmed that wireless interference is the main factor leading to reduced signal quality and poor performance in Ubiquiti 5GHz networks. However, choosing the right polarization, precise routing, and frequency filters can mitigate these effects. Environmental factors and security breaches have also become a significant source of communication problems, requiring the attention of network designers and supervisors to integrate safety and security elements into the design and operation of wireless networks. The study also examined the impact of certain weather factors on signal strength, as well as the effect of similar frequencies. This study focused on one service company, conducted studies and tests on the devices used, and analyzed the signals generated by these devices, assessing their quality and providing the best services. Based on the results, some proposals and recommendations were developed....................
