摘要
分析运行6.4 MHz回传信道频宽后接入网运行质量下降的原因,并分享针对6.4 MHz频宽开展接入网优化的经验,提出了克服6.4 MHz频宽对接入网影响的对策,网络优化后得到明显改善。
This paper analyzes the reason why the running quality of the access network is degraded after running 6. 4MHz back channel bandwidth. Besides,it shares the experience and effect of carrying out the access network optimization for 6. 4MHz bandwidth.
