Research And Implementation Of Cdma Network Covers Based On Telecom Broadband Satellite And Small Base Station

Our country has a vast territory and a wide variety of terrain, and generally speaking, the plains are less than mountains, the west is higher than east, and the terrain of the plateau, desert, basin, and so on, is more than 2/3 of the total area.At the same time, the rapid development of communication technology, promote the production, work, life and other aspects of progress. Especially the popularization of mobile communication technology, the people’s material and spiritual needs is greatly satisfied. However, due to the imbalance of economic development in China and the distribution of the terrain, the mobile communication network cannot cover the whole country. For example, in the mountainous area, the network coverage will be worse than the plain area. Because of the eastern economic developed, the network coverage is more extensive, the western region will be much smaller. Even in the same city, the distribution of base stations is not uniform, resulting in the remote areas away from densely populated areas will be a problem of network coverage.Because of the broadband satellite and small base stations set up CDMA in the domestic has no application precedent, through carrying out the field test can reflect the true situation about CDMA network quality and performance which the small base station using satellite return means, and verify the feasibility of application that is broadband satellite as a small base station backhaul means. The results of the test will be rich China Telecom CDMA network coverages holes in the remote and underdeveloped region, also can for China Telecom Group formulation and implementation of remote areas of CDMA network construction planning, rich in emergencies and natural disaster emergency communication, and provide useful data support and decision-making reference.
