First of all, let's first talk about what is WiFi. WiFi is a technology that connects to the Internet through wireless. The place where you can access the WiFi network is called hotspot. When a WiFi-enabled device (such as a laptop or smartphone) encounters a hotspot, the device can connect to the network wirelessly. Compared with the 2G and 3G networks that need to consume traffic, smartphones or tablets can access the network faster through WiFi and the quality is more stable.
The rapid spread of smartphones and tablets has brought users' eager expectation of always-on, and thus puts higher requirements on the deployment of wireless WiFi for operators.
Comparison of free WiFi solutions of the three major operators
Along with this demand, operators have deployed WiFi hotspots in many cities. We can search for wireless signals on the streets of public transportation, subway, and even urban centers. However, due to some tariff restrictions, they are always used. So effective, but in fact, the three major operators in the WiFi city hotspot deployment process, in order to attract more users, also proposed a lot of time-limited free measures, such a free lunch is a waste of reason, so today The author will sort out the free WiFi solutions and hotspot distribution of the three major operators in Beijing for everyone to choose.
China Mobile:
As a useful supplement to 3G networks, China Mobile has deployed a large number of WiFi hotspots in the Beijing urban area, and has launched a WLAN free experience event since August of 10, and mobile customers can apply monthly for the corresponding WLAN free experience package. Enjoy 20 hours of WLAN free time. From the information displayed on the mobile official website, the current deadline for this event is the end of March 2012.
The mobile user can obtain the WLAN service login password by sending the text message "TYWLAN" to the 10086 self-service free experience package. The package will take effect in the current month of application, and it is very convenient to handle.
According to the mobile official website, China Mobile currently has WLAN coverage in several urban areas in Beijing. According to statistics, Dongcheng District has built 50 hot spots, 48 ​​in Xicheng District, 14 in Chongwen District, 13 in Xuanwu District, and Haidian District. 79, 103 in Chaoyang District and 35 in Fengtai District. There are also a few hot spots in Shijingshan, Changping, Shunyi, Yanqing and Miyun, but the whole is concentrated in the central city, covering hotels, airports, railway stations, commercial office buildings, etc. In many areas, friends who need to know can go to the official website of the mobile to view.
China Unicom:
China Unicom has the most mature and fastest networked WCDMA 3G network. In order to alleviate the pressure on 3G networks, China Unicom has also launched a free WiFi hotspot experience. Unicom's post-paid mobile phone users can use the WLAN network for free in unlimited time and unlimited traffic in China Unicom's national WLAN public hotspot coverage area. According to the customer service staff of China Unicom, the current activity has been postponed until the end of March 2012.
As long as it is a Unicom 3G user, you can directly send the SMS “TYWLAN†to the 10010 self-service free package to get the WLAN service login password. The package is immediately applied and will take effect immediately. After the user opens the WiFi service, he can search for and connect to the "China Unicom" wireless network in the public hotspot coverage area. Entering any URL in the browser will open the China Unicom WLAN service portal page, and enter the mobile phone number and login password to complete the login. .
In terms of hotspot coverage, China Unicom has also done a good job. There are more than 1,100 hotspots in various urban areas in Beijing. In the process of network scale construction, China Unicom does not simply pursue more hotspots, but focuses more on coverage. Whether it is comprehensive or not, Unicom has already comprehensively covered key areas such as transportation hubs and universities that have demand for data traffic. Unicom's official website also provides a query for the WiFi hotspots in each city of Unicom.
China Telecom:
In comparison, China Telecom's WLA free experience is even more atmospheric. According to Beijing Telecom's announcement, it will continue to implement free WiFi promotion activities. Users will continue to enjoy free WiFi access before June 30, 2012. Users can register for free online through any mobile phone number, which is not limited to China Telecom Tianyi mobile phone users, and users of other operators can also use it. According to the previously disclosed WiFi free policy, users can register for free online through any mobile phone number. Tianyi mobile phone users will give 10 hours of free WiFi Internet access per month, and other users will give 5 hours of free WiFi Internet access per month. Beijing Telecom only counts long-term traffic.
The specific use method is as follows. First, when the user uses a terminal such as a mobile phone or a computer, first select China Telecom's wireless network name "Chinanet" on the wireless network, and then click "Connect". Then, when the user opens the browser, the Beijing Telecom WiFi authentication page will pop up. If it is a Chinese telecom user, you can directly enter the mobile phone number and password. If you forget the password or its network user, you can enter the mobile phone number, and then click "Get Password." ", the system will automatically send a text message to the user's mobile phone, users can use Beijing Telecom WiFi with this temporary password.
Regarding WiFi coverage, Beijing Telecom's internal information shows that in addition to the most important places such as the Capital Airport, Beijing Telecom has opened WiFi in Financial Street and International Trade Zone. Among them, the financial street WiFi coverage includes West Second Ring Road, Chang'an. Street North, Fuchengmen Inner Street South, Taipingqiao Street West; In addition, Sanlitun, Yansha, Dongzhimen and other areas will also be opened in the near future. If you want to find the location of WiFi hotspot coverage of Beijing Telecom, you only need to enter "wifi" through Baidu map to find it.
Finally, I want to remind everyone that there are many free WLAN accounts and passwords on the Internet that are known as Mobile, China Unicom, Telecom or McDonald's, KFC, etc., such as the following: "Free WIFI account password ~hoho~ China Mobile (micro Bo) CMCC card number card number card number card password are: 159258 China Telecom (microblogging) hotspot coverage, the national public account number 07953591377 password 3591377; McDonald's (microblogging) account: McDonald-OC password Ac28Idfjla92ifjsl3jsHdowIo. "I believe everyone has seen Over.
But only through a simple test can be found that these so-called free accounts and passwords are wirelessly logged into the Internet, which indicates that the network pass WIFI account password is not a fact. Now the free WLAN initiatives of the three major operators are only to attract users, but also to alleviate the pressure of 3G. As for the WLAN is free or charge after the wireless city is built in the future, it is still inconclusive, but the free experience activity is a kind of Huimin. Policy, it can be a good thing for users to contribute less to operators.
