Current paper give the review of wireless communications used in transport systems and offer the approach to control quality of service (QoS) under weather-based disruptions in transport systems. The introduction – shows the actuality of current topic. Currently, the most relevant form of communication and data transferring in transport systems is wireless. Therefore, to ensure the proper level of service and security in transport systems, it is necessary to ensure uninterrupted communication in all weather conditions. The above is due to the relevance of this article. The goal of the research also is defined here - the aim of this work is to review the wireless technologies used in transport systems and offer solutions to improve the quality of service when using wireless technologies in all weather conditions. Any information processes in a particular system are associated with the transfer of information between objects or subjects of information interaction. Therefore, it is actual also for transport systems. Wireless networks used in transport systems are classified here according to the classification of the International Telecommunication Union (ITU). Among individual sub-technologies, there are varieties of solutions that differ from each other according to different criteria. As a result, the key ones are selected here. Given the negative impact of weather on wireless, it is obvious that in order to increase QoS, you should try to maximize the uninterrupted availability of all system functions, regardless of the availability of each of the communication channels at any given time. This can be achieved by using duplicating various communication channels, constant monitoring of the system and instant response to malfunctions by eliminating them. A short review of two practical examples are also given in article. The approach - how to increase quality of service in transport system is offered.
