One of the biggest challenges for wireless communication network operators is how to minimize or mitigate radio frequency interference (RFI) for efficient network services at the desired quality of service (QoS). Microwave radio links are highly susceptible to interference from narrow and wideband sources. Interference ultimately affects network quality and contributes to the colossal loss of usable mobile data, leading to substantial operational costs for network operators. Additionally, the implementation of high capacity microwave links could potentially force the channels to point towards the same direction, posing a significant interference source. Radio frequency interference issues on the microwave links should be prioritized for prompt resolution or mitigation to achieve the minimum QoS requirement for the growing network subscribers. Toward this end, frequency scans are required to accurately picture the available frequency plan and channels based on the allocated spectrum. This article presents experimental data on radio frequency interference of active microwave links at 6 GHz, 7 GHz, and 8 GHz. The extensive frequency scans were obtained from eighteen active base stations located in Kogi, Lagos, and Rivers States in Nigeria. The frequency scans were carried out using the Anritsu MS2724C spectrum analyzer and a 0.6-meter antenna dish with full azimuth coverage. The analyzer captures the horizontal and vertical polarization. The frequency scan measurements reported in this article would be significantly useful to radio frequency interference detection and mitigation, preliminary network equipment positioning, frequency selection and assignment, and microwave network planning.
无线通信网络运营商面临的最大挑战之一是如何将射频干扰（RFI）降至最低或减轻，以在所需的服务质量（QoS）下实现高效的网络服务。微波无线电链路极易受到窄带和宽带源的干扰。干扰最终会影响网络质量，并导致大量可用移动数据的巨大损失，给网络运营商带来高昂的运营成本。此外，高容量微波链路的实施可能会迫使信道指向同一方向，从而构成重大干扰源。应优先解决或减轻微波链路上的射频干扰问题，以满足不断增长的网络用户的最低QoS要求。为此，需要进行频率扫描，以根据分配的频谱准确描绘可用的频率规划和信道。本文展示了在6GHz、7GHz和8GHz频段对有源微波链路进行射频干扰的实验数据。这些广泛的频率扫描数据来自尼日利亚科吉州、拉各斯州和河流州的18个有源基站。频率扫描使用安立MS2724C频谱分析仪和一个全方位覆盖的0.6米天线抛物面进行。该分析仪可捕获水平和垂直极化。本文报道的频率扫描测量结果对于射频干扰检测与减轻、网络设备初步定位、频率选择与分配以及微波网络规划将具有重要意义。
