With the gradual development of water transportation port information digitization, the traditional way of communication restricts the information interaction of a port to a certain extent. Analyzing the demands of communication service and corresponding characteristics, combining with the technical advantage of TD-SCDMA system and its application in public network, the paper presents a wireless enterprise network system solution for water transportation port, and analyzes the business performance of the system, which can provide effectively highquality voice, high-rate data transmission services, as well as remote video surveillance service, etc. , and can be effective in increasing productivity and communications capabilities for water transportation.
