4G wirele communication network
Today，I will introduce a technology---The fourth-generation wirele communication, As we all know，3g open the multi-media age。I believe we all experience the 3g which bring a change of life, we use 3g mobile phone to surf internet, watch movies, write micro-blogand so on!With the development of technology,researchers began to develop 4g network.first，what is 4g, simple speak it's the enhanced version of 3g, it contains 3g functionality and break through the limit.What is the important symbol of the progre of each generation of wirele communication networks ,The answer is transmiion speed。4g network has a higher transmiion speed and bring more fun experience, 4G is a kind of broadband mobile communication system with broadband channel and distributed IP architecturenetwork。in the static and hot scenarios, the transmiion rate can reach 1g bit / s, in the dynamic, such as, when you traveling by high-speed train, the transmiion speed can reach 100M bit / s, this speed is 10times fast than 3g network , you've never experienced such high speed in today's electronic products。Give an example，a 5 MB MP3 format only need one second download completely, a 40g HD movie finished just 2 hours, but usea 4 megabytes of broadband.need one day
In addition the high speed feature, there are many other characteristics in 4G network, first, it coexist variety of wirele networks, such as the WLAN, 2G, 3G, GPSbroadcast networks etc., so it can be widely used.second, it owe 100 times the capacity of 3G system ,next, the seamle global coverage, it can be used in any time and place , and can provide a personalized service.Based on these characteristics, Multi-network compatible, high-speed and seamle coverage, build a powerful 4g system, ,one day just a 4g phone card can Integration function ofcomputer, game machine, digital camera, scanner, bank cards.this will changes in the way of entertainment For example, you would use 4g phones play team games, just One mobile phone is set to host，others shared signal.Like set up a local area network, everyone can play the game。it brings change that phone is getting closer to the computer's functions.Entertainment isthe tip of the iceberg of its function, I think it will bring some revolutions.In China, many remote areas, Due to the inconvenience of cable laying and construction of the signal tower, the information communication is poor in this areas，4G will change the situation。because the bottle neck of wireletransmiion speed be break, a small device can replace the traditional facilities ,and build the network easily without cable.so city and rural infrastructure is expected to realize intelligent.At the same time, it also bring some advanced product in the movie--miion impoible 4, a BMW roadster with enhanced navigation, it is so cool, may be this kind of navigation will be widely used years later, the Apple Corp will also design a good mobile phone to apply network, launchediPhone 6。Now, the good news is that China Mobile Corp is doing application test of 4G network in Hangzhou an received good result.when the technology become matures, it will be running commercially in Hongkong ,first.Than is all of my topic.Thank you for listening.
