数字集群系统越区切换与隧间漏缆连接

轨道交通无线调度主要应用数字集群系统的语音通信功能,通话质量是衡量系统好坏的重要指标,而是否可以进行平滑的越区切换又制约着系统通话质量。在轨道交通无线覆盖领域,采取何种隧间漏缆连接方式是保证越区切换的核心、是工程项目人员关注的重点。

Digital Trunking System switching site with different leakage coaxial cable connected type in the tunnel center

Voice communication is one of the Digital Trunking System main functions in Metro dispatch field, and voice quality plays a key roll in the service benchmark system. In voice service, one of the most important factors is the smooth switchover which provides the system with good roaming service. In Metro RF system where leakage coaxial cable is always implemented, the cable connected type in tunnel center is the key to smooth switchover or roaming, good design will lead to good coverage and convenient roaming, which system engineers pay great attention to.
