Introduction of 80GHz band E-Band microwave applications

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 fiber resources, the domestic estimated 20% of the new site fiber resources missing, making LTE base station service return and PTN fiber network loop are under pressure. As an important solution of ...

The second generation of E-Band microwave: the choice of LTE Era

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 narrow beams to adapt to intensive deployment and other advantages, gradually from the traditional enterprises. The application of the industry market to the carrier class large bandwidth business bearer network development.E-Band can deal with large capacity backhaul easilyE-Band is the microwave frequency band of 80GHz (71-76GHz and 81-86GHz), which is the highest frequency band for commercial ...

Intelligent radar and its key technologies

With the rapid development of artificial intelligence technology and its gradual application in the military field, intelligent radar and intelligent radar technology have attracted wide attention at home and abroad. Strengthening the research of intelligent radar and its key technology is not only the need of radar technology development, but also the key to improve radar combat capability.1. IntroductionTraditional radar works mainly according to the pre-designed working mode. It has no ability to change the working mode automatically with the change of the target and environment, and it has insufficient adaptability to the target and environment. Although adaptive signal processing technology has been widely used to improve radar anti-clutter, anti-jamming and other aspects of performance, but because adaptive signal processing requires the signal to be processed to satisfy the ideal conditions of stationary characteristics in order to obtain satisfactory performance, so the actual ...
