Green belt area Solution

　　Green belt areas, highways and other areas. Housing density, larger traffic flow, high levels of traffic and business needs. Currently the number of base stations along the streets within an average of five macro base station / km2 丆 spacing 300 ~ 400m 丆 base station configurations are larger, property requirements, construction difficult, the optimal adjustment of high frequency. Therefore, such areas should be "multiple access" technology-based, centralized base station equipment appropriate to reduce the difficulty of maintenance construction and adjustment in order to increase the signal strength and the capacity configured as the primary coverage.
