On December 4, the Ministry of Industry and Information Technology officially issued TD-LTE 4G licences to China Mobile, China Telecom and China Unicom, and China officially entered the era of 4G. According to a report by GSMA Intelligence, a third-party analyst, more than 128 countries will deploy about 500 LTE networks by the end of 2017. 4G not only provides more bandwidth and brings better mobile Internet experience to people, but also challenges the carrier's mobile bearer network.With the issuance of 4G licenses in China, the LTE network will be deployed quickly. However, LTE base station coverage is small, deployment density is much higher than GSM base station and 3G base station, LTE construction will face a large number of new site demand, and part of the new site shortage of...

With the rapid development of mobile broadband, the network capacity is growing rapidly. As one of the main return modes of bearer network, microwave network is facing the dual challenges of super-large service capacity and densely deployed stations. Traditional band microwave (6-42GHz) spectrum resources are becoming increasingly scarce, bandwidth capacity is limited, it is difficult to meet the G-bit-level large bandwidth stations to return the demand, and E-Band microwave (80GHz) because of its rich bandwidth resources, large transmission capacity, low spectrum usage fees and high-frequency...
