First of all, let ’s talk about what WiFi is. WiFi is a technology that connects to the Internet wirelessly. The place that can access the WiFi network is called a hotspot. When a device that supports WiFi (such as a laptop or smartphone) encounters a hotspot, the device can connect to the network wirelessly. Compared with the traffic consumption of 2G and 3G networks, smartphones or tablets access the network faster via WiFi, and the quality is more stable.
The rapid popularization of smart phones and tablet computers has brought users' eager expectations for always-on, which also puts forward higher requirements for the deployment of wireless WiFi by operators.
Comparison of free WiFi solutions of the three major operators
With this demand, operators have set up WiFi hotspots in many cities. We can search for wireless signals on buses, subways, and even the streets of urban centers, but due to some tariff restrictions, they are always not used. So effective, in fact, in the process of WiFi city hotspot deployment, the three major operators also put forward a lot of free time-limited measures in order to attract more users. Is such a free lunch wasteful, so today The author sorts out the free WiFi solutions and hotspot distribution of the three major operators in Beijing for everyone to choose applications.
China Mobile:
As a useful supplement to the 3G network, China Mobile has deployed a large number of WiFi hotspots in the urban area of ​​Beijing, and has launched WLAN free experience activities since August 10th. After mobile customers have applied for the corresponding WLAN free experience packages, they can Enjoy 20 hours of free WLAN. From the information displayed on the mobile website, the current deadline for this event is the end of March 2012.
Mobile users can obtain the WLAN service login password by sending the SMS "TYWLAN" to 10086 to open the free trial package. The package will take effect in the month of application, and it is also very convenient to handle.
According to the mobile website, China Mobile currently has WLAN coverage in many urban areas in Beijing. According to statistics, 50 hotspots have been built in Dongcheng District, 48 in Xicheng District, 14 in Chongwen District, 13 in Xuanwu District, and 13 in Haidian District. 79, 103 in Chaoyang District and 35 in Fengtai District. There are also a few hot spots in Shijingshan, Changping, Shunyi, Yanqing, Miyun, etc., but the whole is still concentrated in the central city, covering hotels, airports, railway stations, business offices, etc. In multiple regions, friends who need to know can go to the mobile official website to check.
China Unicom:
Unicom has the most mature technology and the fastest WCDMA standard 3G network. In order to alleviate the pressure on the 3G network, Unicom has also launched a free WiFi hotspot experience activity. Unicom postpaid mobile phone users can use the WLAN network free of charge for unlimited time and unlimited traffic in the coverage area of ​​China Unicom's WLAN public hotspots. According to the Unicom customer service staff, this activity has been postponed until the end of March 2012.
As long as you are a Unicom 3G user, you can directly send a short message "TYWLAN" to 10010 to open a self-service free plan to obtain the WLAN service login password. The package is applied immediately and takes effect immediately. After opening the WiFi service, users can search and connect to the "ChinaUnicom" wireless network in the public hotspot coverage area, enter any URL in the browser to open the China Unicom WLAN business portal page, and enter the mobile phone number and login password according to the prompt to complete the login .
In terms of hotspot coverage, China Unicom has also done an excellent job. There are more than 1100 hotspots in various urban areas in Beijing. In the process of network scale construction, China Unicom did not simply pursue more hotspots, but focused more on coverage. Whether it is comprehensive or not, at present, Unicom has comprehensively covered key areas that require data traffic such as transportation hubs and universities. Unicom's official website also provides a query and combing of WiFi hotspots in various cities of Unicom.
China Telecom:
In comparison, China Telecom ’s WLA free experience is more atmospheric. According to Beijing Telecom ’s announcement, it will continue to implement free WiFi promotions. Before June 30, 2012, users can continue to enjoy free WiFi Internet access. Users can register for Internet access for free through any mobile phone number, not limited to China Telecom Tianyi mobile phone users, but also users of other operators. According to the WiFi free policy previously disclosed, users can register for Internet access for free through any mobile phone number. Among them, Tianyi mobile phone users are given 10 hours of free WiFi Internet access per month, and other network users are given 5 hours of free WiFi Internet access per month. Beijing Telecom only counts time and does not count traffic.
The specific method of use is, first, when users use terminals such as mobile phones or computers, they 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 China Telecom user, you can directly enter the mobile phone number and password. If you forget the password or other network users, 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 this temporary password to use Beijing Telecom WiFi.
Regarding WiFi coverage, Beijing Telecom ’s internal information shows that, in addition to the most important places such as the Capital Airport, currently, Beijing Telecom ’s WiFi in Financial Street and International Trade Zone has been opened. Among them, Financial Street ’s WiFi coverage includes West Second Ring Road East, Chang’an North of the street, south of Fuchengmen Inner Street, west of Taipingqiao Street; in addition, Sanlitun, Yansha, Dongzhimen and other areas will also be opened in the near future. If you want to find the location of Beijing Telecom's WiFi hotspot coverage, 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 claimed to be mobile, China Unicom, Telecom, 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 number password are: 159258 hot coverage of China Telecom (microblogging), national public free account 07953591377 password 3591377; McDonald's (microblogging) account: McDonald-OC password Ac28Idfjla92ifjsl3jsHdowIo. "I believe everyone has seen Ever.
But it only needs to pass a simple test to find that these so-called free accounts and passwords simply log in to the Internet wirelessly, which shows that the password of the WIFI account is not a fact. The free WLAN initiatives of the three major operators are just to attract users, and can also relieve the pressure of 3G. As for the construction of wireless cities in the future, whether WLAN is free or charged, it is still inconclusive, but the free experience activity is ultimately a benefit Policies, which can contribute less to operators, are naturally a good thing for users.
