    <subfield code="a">&lt;p&gt;Railway transport is effective and reliable only if it has best communication and signaling system with safety, reliability and good quality of service which are maintained by railway management and communication system. By implementing latest technologies for railway communication railway transportation can be made safer, efficient, and more accessible. This research work focuses on the study of Ultra wide band (UWB) radio based wireless communication system as an auxiliary or alternative communication system for Addis Ababa Light rail transit (AA-LRT) tunnel at piassa (Gyorgis), whose main task is to maintain an uninterrupted data transmission between train driver to wayside controller. The much larger bandwidth of ultra-wideband allows a very high data rate (up to maximum 480 Mbps), which is beneficial in case of emergency in railway networks.&lt;/p&gt;</subfield>
