Network access system for public transportation

Abstract

The invention provides a network access system for public transportation. The network access system for public transportation comprises a remote control center and a plurality of WLAN base stations. Each WLAN base station has access to the internet through a cellular network base station of a 3G network, and the remote control center has access to the internet as well and is in communication with each WLAN base station through a general routing packaging channel; the remote control center comprises a wireless control server and a database and a public transportation WLAN management platform is deployed by the remote control center and used for managing and maintaining each WLAN base station. The network access system for public transportation can satisfy the requirements that multiple users can surf the internet simultaneously and high-definition videos in a wireless network can be played. The network access system for public transportation is simple in structure, convenient to install, rapid in installation and stable in performance; unified management and maintenance can be conducted and various network attacks or other emergencies can be prevented.

Description

technical field [0001] The invention relates to the fields of communication technology and Internet technology, in particular, the invention relates to a network access system for public transportation. Background technique [0002] With the popularity of smart devices and tablet computers and the expansion of network applications, people often use these terminal devices for leisure and entertainment when taking public transportation. However, there is no WIFI coverage in public transportation, 2G Internet access is slow, and 3G Internet access is low in utilization rate on the one hand and expensive on the other hand. The cost of watching video and audio through mobile phones or tablets is unaffordable for ordinary users. [0003] Huawei E5 is a mobile router that can access 3G network. It can be placed in the car to realize multi-user WIFI Internet access. However, Huawei E5 can only support up to 5 users, which cannot meet the WIFI coverage requirements in public transpo...

AI Technical Summary

Problems solved by technology

However, Huawei E5 can only support up to 5 users, which cannot meet the WIFI coverage requirements in public transportation

Moreover, Huawei E5 cannot perform unified management and maintenance and prevent various network attacks or other emergencies

[0004] There are other vehicle-mounted WIFI devices in the prior art, such as: Chinese patent applications 201110436866.3, 201120265643.0, 200910087866.X, but they are not designed for public transportation systems, and it is difficult to support multiple users to surf the Internet at the same time, and it is impossible to perform unified management and Maintenance, in case of equipment failure, you can only go to the place where the equipment is installed for maintenance

In addition, they are also difficult to prevent various cyber attacks or other emergencies
