CBTC系统中2.4GHz WLAN技术的替代方案

Alternative Scheme of 2.4GHz WLAN Technology in CBTC System

介绍了 2.4 GHz WLAN技术的方案.简要介绍 了裂缝波导管技术、泄漏同轴电缆技术,以及1.8 GHz LTE 技术、 1.8 GHz DVB-T技术、 5 .8 GHz WLAN技术.分析 了替代方案中的5.8 GHz WLAN方案、信威 400 MHz方 案、 2.4 GHz移频至 1. 8 GHz WLAN 方案、 1. 4 GHz LTE 方案及1.8 GHzLTE方案,并对各方案进行比选,最终选定 1.8 GHz LTE方案作为最佳方案.

2.4 GHz WLAN technology is introduced, inclu-ding crack waveguide technology, leaky coaxial cable tech-nology, 1. 8 GHz LTE technology, 1. 8 GHz DVB - Ttechnology and 5. 8 GHz WLAN technology. Then, 5. 8GHz WLAN solution, Xinwei 400 MHz, frequency shift from 2. 4 GHz to 1. 8 GHz WLAN technology, 1. 4 GHzLTE and 1. 8 GHz LTE in the alternative schemeare ana-lyzed. Through comparison of all the schemes, 1. 8 GHzLTE is selected as the best one.
