摘 要:为研究4G高增益天线在农村地区的覆盖效果,为农村地区的网络建设提供指导和借鉴,选取农村地区的典型场景:高速、平原、丘陵、山区作为现场测试研究对象,通过理论分析和实际测试对比来验证4G高增益天线与4G普通天线、GSM天线的覆盖效果差异。研究结果表明,在农村无阻挡高站的情况下使用4G高增益天线能明显提升中远场信号强度,近场信号恶化不明显,覆盖距离能达到普通天线的1.23倍左右,与GSM天线的覆盖距离相当,大约能节省15%的建设成本。In order to study the coverage effect of 4G high gain antenna and provide the guide and reference to the network construction in rural areas, typical scenarios in rural areas including expressway, plain, hills and mountains were selected to be the researching and testing objects. Then, the differences of coverage effect of 4G high-gain antenna, ordinary antenna and GSM antenna were compared through the theoretical analysis and practical test. Results demonstrate that the use of 4G high-gain antenna in the case of rural high site without blocking can dramatically enhance the signal strength of medium and thr field, but the near-field signal hardly deteriorates; its coverage distance can reach 1.23 times of the ordinary antenna basically equivalent to the coverage of GSM antenna, In addition, 15% of the construction cost can be saved.
关 键 词:4G高增益天线 农村地区网络覆盖 链路预算 覆盖半径
