Abstract

The invention relates to a simulation method and equipment for polarization staggered coverage between cells. The method of the invention includes: setting a vertical polarization layer network by using the horizontal-vertical polarization isolation value, and setting the horizontal polarization layer network by using the vertical-horizontal polarization isolation value. Polarization layer network; respectively simulate the set vertical polarization layer network and horizontal polarization layer network, and obtain the basic wireless index results corresponding to all geographic points in the vertical polarization layer network and horizontal polarization layer network; for each geographic point, select the terminal antenna polarization direction with the best basic wireless index, and obtain the simulation result layer corresponding to the terminal antenna polarization direction; according to the simulation result layer corresponding to each geographical point, draw the terminal polarization direction and each Geographical distribution map of various indicators. The invention is simple and practical, can realize the coverage simulation under the condition of cell polarization interleaving, improves the network planning and design ability, improves the prediction and analysis level, and shortens the planning and design cycle.

Description

technical field [0001] The invention designs the wireless planning of the cellular wireless communication network and the aviation public communication, and particularly relates to a polarization interleaved coverage simulation method and equipment between cells. Background technique [0002] Since 2007, the ground-air coverage network of the third generation mobile communication system (cdma2000 EVDO) has been put into commercial operation in a developed country. Since 2010, China's domestic airlines have also begun to consider introducing ground-air coverage operations with appropriate technology and business models. [0003] The ground-air coverage network is composed of the air system on the aircraft and the base station system on the ground. Among them, the ground base station system is transformed from a traditional mobile communication base station, and the main lobe direction of the antenna gain covers upwards. The continuous coverage of the air route can be achieve...

Problems solved by technology

[0007] The existing network simulation software has realized the simulation prediction of ground-air network coverage of signals in a single polarization direction, but has not yet realized the simulation function of polarization direction interleaving between cells, so it is impossible to predict and display the geographicalization of wireless performance parameters after adopting this technology The distribution effect is a major deficiency in the ground-air network simulation technology, which limits the improvement of the level of wireless planning and design
