发明名称 A THREE-DIMENSIONAL SPACE COVERAGE CELLULAR NETWORK
摘要 Network, method and base station are disclosed to establish a three- dimensional space coverage cellular telecommunications network for providing cellular signals coverage on the ground and in space above the ground, especially in high-rise buildings, in a cellular telecommunications system. An up-tilt antenna and a down-tilt antenna are coupled to the same base station transceivers, so as t o share the base station and frequency spectrum, and to avoid interferences. The down-tilt antenna covers the ground; the up-tilt antenna covers space above the ground, especially the upper floors of high-rise buildings in its cell. The up-tilt antenna and the down-tilt antenna may be integrated into one antenna.
