基于漏泄电缆的井下CDMA无线覆盖技术
Wireless Coverage Technology of Underground CDMA System Based on Leakage Cable
摘要
Abstract
For problems of signal diffraction and bad penetrating ability when using antenna as coverage equipment of CDMA wireless communication system, no way to ensure coverage distance and signal quality of wireless signal in entry with large bending degree and ups and downs, no way to freely improve emitting power of mine-used CDMA base station to meet requirement of wireless signal coverage, a solution of underground CDMA wireless signal coverage with leakage cable was proposed. RF signal output by underground CDMA base station can be connected to leakage cable through two-way power divider and realize coverage of wireless signal of entry. The practical application showed that the signal coverage is stable and communication effect is good by use of the scheme.关键词
