Region based layered wireless information publishing, searching and communicating application system

Abstract

The invention discloses wireless information releasing searching communicating application system which can delaminate according to district. It includes customer access, wide area network, server, and data bank. The customer access is accessed into the internet by Wi-Fi AP or Wi-Fi subset which has user certification, signature, deciphering key. The information is divided into country, city, sector, and hot spot. In addition, the system defines identity certification, accessing control, and wireless information transmission protocols etc. Thus the invention can be used to build unified commercial Wi-Fi network in whole country or all over the world to supply data communication platform for the user.

Description

technical field [0001] The present invention relates to the fields of wireless communication, network and information technology, in particular to a system technology for wireless network information release, search and exchange applications based on Wi-Fi, Internet and PKI. Background technique [0002] IEEE 802.11 wireless local area network (Wi-Fi) protocol standards include 802.11, 802.11a, 802.11b, 802.11g, 802.11i, 802.11h, 802.11e, 802.11n, etc., and new drafts of higher-speed and safer protocol standards are constantly emerging For example, China has proposed its own mandatory national standard WAPI (GB 15629.11-2003). As an alternative to wired networks for computer data communications, Wi-Fi has been widely used in enterprise networking. However, if a nationwide Wi-Fi network is to be built, there is currently a lack of sufficient applications as business support. The actual launch of Wi-Fi phones, such as Wi-Fi mobile phones, will not only be restricted by govern...

AI Technical Summary

Problems solved by technology

However, if a nationwide Wi-Fi network is to be built, there is currently a lack of sufficient applications as business support. The actual launch of Wi-Fi phones, such as Wi-Fi mobile phones, will not only be restricted by government policies if they want to compete with mobile voice service operators. It can never be compared with mobile communication networks such as 2.5G, 3G, and 4G in terms of network coverage, high-speed mobility, and voice communication service quality.

However, some cities in developed countries are funded by the government to build Wi-Fi hotspots in public places as urban infrastructure, and their applications are basically limited to wireless Internet access for users such as laptops, PDAs, and smart phones, and have little commercial value.

[0003] Mobile communication services, mainly voice services, are constantly developing from 2G, 2.5G, and 3G to broadband mobile data communications, but the technology is complicated and the cost is high

The data communication capability below 2.5G is limited. Although 3G and 4G have sufficient data communication capabilities, their data communication is based on the same high coverage and high-speed mobility as voice communication, and they have to bear the same high costs and expenses.

[0017] Although the IEEE 802.11X protocol standard has some security designs, it is not enough to support the security requirements of a very large-scale application network
