In case of failure, it supports speed recovery。因此，信號(hào)系統(tǒng)才能夠在任何一種情形下保證最大的無線覆蓋率和最小的通訊丟失。 Inside the tunnel, frequency (here is ) within 1,000GHz frequency to be adopted inside the tunnel will bring about the radio signal to produce multiple reflections on the tunnel wall, . socalled “multipath” effect. This means, at some places of the line, the direct signal generated from the radiator and signal reflected back from the wall may overlap together, which will enlarge radio signal. While at some places of the line, the signal reflected back from the wall may reduce the direct signal and result in radio transmission loss or socalled “blackhole”. 這里的主要顧慮是， ?黑洞 ?的產(chǎn)生機(jī)制非常復(fù)雜，它們?nèi)Q于隧道的特性、墻壁的條件、通風(fēng)豎井的位置和車站站臺(tái)等等，因此，在設(shè)計(jì)階段對(duì) ?黑洞 ?效應(yīng)進(jìn)行預(yù)測(cè)幾乎是不可能的。 Since the installation place of Radiax cable has almost the same distance to the vehicle antenna, it greatly reduces multiroute signal, and is able to ensure radio coverage rate required for radio munication system when the radio munication work is designed. So that, it avoids blindness for onsite missionining operation and saves large amount of cost and time. However, all these are almost necessary for LoS antenna inside the tunnel. （ 3） 允許使用低輻射電源 Allow to use lowradiation power supply 其次，由于 Radiax 漏纜安裝的地方離車載天線的距離很短且長(zhǎng)度固定，因此，為保持通信可靠性的無線發(fā)射功率，被極大地減小了。一個(gè)列車 ?遮蔽 ?另一個(gè)列車的問題也能通過安裝較高的天線而消除。增益能顯著地提高鏈路余量，而前后比抑制能減小遠(yuǎn)離天線發(fā)射孔的干擾源（如多路徑效應(yīng)干擾一樣）。 Under normal operation mode, a train receives a movement autholirty limit (MAL) message. This message can ensure safe operation of train. This MAL message is updated with each radio message, normally updated once every one second. 如果由于干擾作用或暫時(shí)性無線通訊中斷，列車損失一個(gè)或兩個(gè)無線通信報(bào)文，列車將以允許的速度繼續(xù)運(yùn)行至最后一個(gè)已知的移動(dòng)授權(quán)限制點(diǎn)，并且一旦無線通信重新建立了，列車將得到一個(gè)更新的移動(dòng)授權(quán)限制報(bào)文，從而可以無干擾的繼續(xù)它的運(yùn)行。 Design concept of CITYFLO 650 allows transicent loss of radio munication, which will neither affect system safety nor require to apply emergency brake method to ensure system safety. 在正常的運(yùn)行模式下，列車接收一個(gè)移動(dòng)授權(quán)限制（ MAL）報(bào)文，該報(bào)文可以保證列車安全的運(yùn)行。 In an open radio munication system, multiroute effect problem is relatively not so serious. Because the reflection effect can only take place at an area surrouned by the buldings instead of the above said tunnel wall, the problem of one train to “shade” another train can also be removed by the antenna mounted at high position. Therefore, Bombardier uses LoS antenna?s radio munication ssytem at open area without tunnel wall or roof. LoS 方式需要在列車和軌旁都安裝定向天線。 Second, because the installation location of Radiax cable has a short distance to the vehicle antenna and the length is fixed, therefore, in order ot keep radio radiation power for munication reliability, the distance is greatly reduced. Thus, it will further reduce multiroute signal and make the hearing from any other person or attempt of interference radio signal very difficult.

Therefore, dynamic factor has to be considered when multiroute effect is taken into account.
