News background:

The official issuance of 3G license marks the real arrival of the new communication era, and as an ordinary mobile phone user, it can be regarded as a step across the 3G threshold. We will find that mobile phones in the 3G era are not only mobile phones, but also computers, televisions, live broadcasts, navigators, game consoles and credit cards. We took out our mobile phones, maybe not making phone calls, but swiping credit cards. What changes will 3G bring to us?

How to upgrade the average user's 2G mobile phone?

Former China mobile users: Just change to a dual-mode mobile phone.

China Mobile has a "three noes" attitude towards 3G upgrade-2G users become 3G users, "no change of numbers, no change of cards, no registration".

At the end of 2008, China Mobile completed the integration of TD-SCDMA and the core network of 2G network, which enabled the existing 2G users to use 3G services conveniently by replacing a dual-mode mobile phone without changing their numbers, cards or numbers.

A few days ago, Wang Jianzhou, president of China Mobile, said that when users change their mobile phones, they will be automatically upgraded to 3G users, and all the new functions of 3G can be applied. If users don't change their mobile phones, all 2G services will be used as usual.

If you want to keep the original 2G number, you can have the 3G number segment of China Mobile ~ 188, or you can use a mobile phone with two cards. Wang Jianzhou revealed that China Mobile has started negotiations with various mobile phone manufacturers at home and abroad. "I hope that all 2G mobile phones in the future can be equipped with TD function, that is, new mobile phones should not only have 2G function, but also have 3G function."

New users of China Telecom

Deposit-free and phone-free mobile phone

To achieve multi-function, users need to buy a number of 189 and a CDMA 3G mobile phone.

At present, users of Beijing Telecom can choose a mobile phone for free as long as they pre-store a certain phone bill and promise to reach the minimum consumption quota every month and use the number for a certain number of years. Eight brands, including dopod and Motorola, participated in the event, and the prices of most terminals ranged from 268 yuan to 1980 yuan.

Changes brought by 3G

Switch to 1 mobile phone and enter the video era.

● Current achievement: ★★★★★ If the legendary clairvoyance has been realized by the 2G mobile phone, the combination of clairvoyance and clairvoyance has been realized by the 3G mobile phone.

3G mobile phones generally have a camera on each side, the camera on the back is used for taking pictures, and the camera on the front is used for video calling. In this way, the user can not only see the other person's face on the screen, but also see his own expression in the lower right corner of the screen, and can adjust his own image to the best angle at any time.

If video calling is not enough, 3G mobile phones are expected to realize "TV calling" in the future. After installing a special set-top box and camera, connect the mobile phone to the TV, and you can "live" the caller on TV while making a phone call. Maybe next year's Spring Festival greetings will have new tricks. Call home and let friends and relatives see you on TV. Heaven still exists, and our neighbors are no longer the beautiful yearning in poetry.

The function of videophone also includes mobile video conference. Take TD as an example. After dialing 12535, you can start the mobile video conference. At present, video conferencing can realize four people talking at the same time.

Change 2 downloading and chatting are no longer stuck.

● Current implementation effect: ★★★★ At present, the speed of wireless Internet access is still within several hundred K, but China Telecom claims that CDMA2000 network will soon make the "average download rate" of wireless Internet access reach 1.2M, and MediaTek plans to launch 3.5G TD chip in the second half of next year, so that the downlink rate of TD mobile phone transmission will reach 2.8M and the uplink rate will reach 2.2m. ..

It takes about half a minute for ordinary 5 12K home broadband to download a 4.5M song through Baidu, while the same song with downlink rate of 1.2M can be downloaded in 4 seconds. If the downlink speed is as high as 2.8M, the song can be downloaded in 2 seconds, literally, in a blink of an eye.

Download is still so fast, not to mention the basic functions such as opening several web pages, chatting through MSN and QQ, and sending and receiving emails. High-speed Internet access makes it possible for online games to move between the square screens of mobile phones.

China Telecom also said at the release conference of 189 that it will increase the CDMA wireless broadband rate to 2-3M in the next year or two. In hotspots covered by WiFi, the highest rate even reaches 10M. If it is realized, the speed of wireless Internet access can be described as "flying".

At present, there is still a big gap between the speed of 200-300 K per second and the "flying average" network speed. According to the planning of China Mobile and China Telecom, it is expected to achieve the uplink and downlink speed in M in the second half of this year.

Change 3 to watch programs anytime, anywhere.

● Current realization effect: ★★★☆ There are two ways to realize mobile TV, one is through GPRS；; The other is the corresponding broadcast mode. The former allows users to interact with TV, and users can actively order programs and customize services through mobile phones, but the disadvantage is that the generated traffic is expensive; The latter is equivalent to moving the traditional TV screen to the mobile phone, so that people can put the TV in their trouser pockets and entertain themselves anytime and anywhere.

Fresher TV applications are yet to come. South Korea has launched a car TV, which can be connected by mobile phone. After receiving the TV signal, the mobile phone directly transmits it to the TV screen in the car, which solves the problem that the screen of the mobile phone is too small. "Displacement TV" directly connects the mobile phone to the TV. If the user watches TV and sees that half of them have something to go out, the mobile phone can immediately connect to the same channel when the TV is turned off, so that the user will not miss the program on the road.

Of course, these products are still conceptual at present, but when 3G networks mature, they will be introduced to the market.

Changing four video clips can be sent at any time.

● Current achievement: ★☆ The difference between 2G and 3G is almost similar to the difference between a path and an expressway. I used to send a multimedia message and a text message on my mobile phone. There may be traffic jams in Spring Festival travel rush peak. Now, mobile phones can transmit not only MMS and SMS, but also video clips.

You can shoot a short film with the camera of your mobile phone first, and then send it to your relatives and friends' 3G mobile phones. The "road" is wider, and "super trucks" such as video clips can also run smoothly.

In addition, the 3G mobile phone can realize real-time monitoring, and a camera matched with the mobile phone is installed at home. When there is no one at home, you can also observe the situation at home at any time through the mobile phone screen.

At present, the realization of video short film transmission function requires the mobile phone to be powerful enough on the one hand and the communication channel capacity on the other. It is estimated that it will not really enter the practical stage until the second half of this year.

Shopping by car for 5 "one machine"

● Current achievements: ★★★★★ Mobile phones can be used as door keys, credit cards, transportation cards, membership cards and various bills (such as air tickets and train tickets), and can even be directly used for supermarket shopping. Although it sounds incredible now, it is nothing new in countries where 3G is developing rapidly.

Japan is one of the countries with the most incisive mobile phone applications. As the 3G network is very mature, Japanese operators have made mobile phones have many "magic" functions. For example, if you use your mobile phone to take the subway and shop, you only need to swipe your mobile phone on the card reader, and the computer network can directly deduct the subway fare (or the total shopping cost) from the phone bill, which is quick and simple, similar to that of Beijing residents taking the subway with bus cards today.

It is reported that this universal mobile phone model has 22 million users in Japan. Operators in China are also vigorously promoting mobile phone wallets, mobile phone electronic tickets and other services, and China's "universal mobile phone" is gradually becoming a reality. At present, many Beijingers have begun to use mobile wallets and tickets, and some areas have even introduced mobile boat tickets. However, mobile phone credit cards, mobile phone keys and mobile phone transportation cards are still blank in China. (new scene)
