The fifth generation Wi-Fi is coming, it can not only help you put your wireless device is connected so simple.
In the talk about this problem before, we can't help but to count Wi-Fi now of "indictment" : hot too little, network congestion, often drops, signal is too weak. In the lobby and flourishing business center for these people concentrated public, Wi-Fi is simply eroded, can you even have become even on inspection standards of character.
The metropolitan transportation become increasingly bad, as a wireless Internet world of highways, global Wi-Fi network also faces sometimes occur to the situation of traffic jam. Here is "running" cellphone, plate, laptop computers, handheld game, there are all kinds of mobile devices. Wi-Fi alliance in September 2011 to make statistics, union members enterprise has now reached 450, Wi-Fi global users and more than 1 billion, with Wi-Fi the authentication products delivery has over 2 billion a total per year on average, and 2 million products development. At the same time, Internet demand also is in produce change, email, browsing website is only the most basic, people want to see the movies, play games, listening to music, and dealing with various kinds of data.
But the global the fastest Wi-Fi transmission speed only for 300 Mbps (a few can reach 600 Mbps), equivalent to about 36 MB per second can only transmit the content. People use it to see only in web site, processing email s, it's no problem. But today, in the face of use demand more and more complicated, the old technology standards become under. Because it was just a car traffic is expected to the highway, but suddenly packed into the bus and large trucks, and more.
5 G Wi-Fi--the fifth generation Wi-Fi solve is such a problem. It will transfer speed upgrade to 1 Gbps, about 125 MB per second can transfer the content. With the highest content of transmission bandwidth requirements high-definition movie as an example of words, a high-definition movie of data per second in circulation often 30 to 45 MB between, or even higher. 5 G Wi-Fi does not only meet the transmission conditions, much hi-def movies transmission is not problem, also means that it can hold more users, not because of excessive number and produce congestion.
This product is a production of American broadcom, a wired and wireless communications semiconductor solutions provider, is the world's largest wireless Internet providers of WLAN chip. The company predicts, the late in the end of 2012, installed the 5 G Wi-Fi chip digital electronic equipment will appear on the market.
This is a good news, 5 G Wi-Fi first appeared on the civil products, it consists of industry the most representative company production, it will be more and more popular. It is called the fifth generation standard, because it is in the United States IEEE wireless Internet LAN standard 802.11 in the launch of the fifth, was named 802.11 ac.
We can through the review the history, look at this some hard to remember the noun how one and the same. In the global civil wireless network, commonly used is the transmission and reception of 2.4 GHz band signal, followed by 5 GHz. The higher the signal frequency band, Wi-Fi chips working band of the higher the manufacture process and also more complicated. In 1997, when the first generation of Wi-Fi standard appeared, the process and the cost by restrictions, the working frequency of chip only 2.4 GHz in fixed, the highest transmission rate only 2 Mbps, equivalent to about 0.016 MB per second can only transmit the content in the most-to start, Wi-Fi also is only a narrow trail.
But it soon started to become highway, the ensuing 802.11 a and 802.11 b, 802.11 g and 802.11 n, version of the standard and quicker. In 2004, for example, the launch of the 802.11 n before 802.11 g 10 times faster than the earlier 802.11 b fast 50 times, coverage is more widely. Just although Wi-Fi chip transmission speed like sitting all the way up the helicopter growth, but still can't catch up with the demands of the people.
The new 5 G Wi-Fi, namely 802.11 ac, the working frequency of 5 GHz chip, and 5 GHz can cover and 2.4 GHz two big band. In addition to faster, it can improve the wireless signal coverage small problems, although 5 GHz 2.4 GHz more difficult than direct around obstructions, but because the coverage is more big, considering the signal will produce the refraction, new standard instead can more easily each corner to receive signals; The new standard of another big advantage is energy saving, efficiency is the power of the generation before six times. Due to the transfer of the same time more content, equipment can also faster access to low power save electricity mode.
More quickly through the ability, more comprehensive coverage, and let the 5 G Wi-Fi a veritable information highway. In the mobile Internet terminals of popular today, this means that a network with more may be in the future.
There are two big organization in it played a key role, and that is IEEE and Wi-Fi alliance.
IEEE is the American electrical and electronic engineers (IEEE abbreviation, is it the world's largest professional technology organizations, members from the 175 countries research institutions and universities, has many kinds of research group, for numerous formulate industry general standard technology, IEEE 802.11 is one of them, the wireless local area network is in general. Want to make the general standard, it is to let a wireless network with other related industrial products can be the product line.
At the same time in the wireless network field, different manufacturers of products is also need to be able to be compatible, so in 1999, the industry some of the major wireless equipment maker founded the alliance, in 2000 the alliance officially changed its name to Wi-Fi alliance. "Wi-Fi" was just the alliance held the authentication trademark, the trademark of a wireless equipment can be between compatible with each other. Today, Wi-Fi finally broke through the narrow meaning when it was born, almost become the pronoun of wireless broadband access technology-although it is not the only a infinite LAN technology, Wi-Fi league in which play an important role in promoting.
As early as in 2006, the President of the union Wi-Fi Andrew Myle assume a everything has Wi-Fi intelligent world: before you go home, you Wi-Fi air conditioning has put the indoor temperature transferred to you like 20 degrees Celsius, Wi-Fi electric meal bao of sweet soft rice can always out of the pot; Busy in the kitchen of intermittent, you can use the Wi-Fi microwave oven to listen to a radio station, and family phone; Can let you save worry and Wi-Fi electric meter, it will be monitoring electricity use, in the remaining power for zero remind you of prepaid phone...... before
Now there are no people think these just science fiction movie scene. Can adjust of power consumption of the intelligent Wi-Fi meters in the United States has started to popularize, and ability to download the latest cookbook microwave oven, or let housewife in the kitchen of the conversation with family video refrigerator, also in some people's home to become a reality. In 2012, soon after just of the exhibition CES, samsung (the Po), LG, haier company, are introduced with Wi-Fi connection function of refrigerators, washing machines, electrical home appliances products such as the dryer white. It is for these traditional Wi-Fi home appliance modern up again, and digital mobile products stand to the same stage.
In China, more and more companies are also beginning to join Wi-Fi alliance, huawei (the Po) company became Wi-Fi alliance members of the board of the directors and sponsors, the newly join the alliance member of China enterprise also include China mobile (the Po). And this place, as it is known to all, have already become the world's largest mobile phone market.
Note to Wi-Fi potential also includes those famous car company. In them for a "future car" plan, Wi-Fi will is to realize people, vehicles and external environment information exchange between the important technology. The ford motor company in ideas, data from your car will be sent to the Google data center, so that each engine ignition forecast to go to place, if is a hybrid car users, so they can drive to decide when to switch to the battery power supply, and the choice of a mountain road at least, without the rain, the smallest of the more fuel efficient cars driving route. From the view of economic, these can use those across the city, Wi-Fi hot to complete.
An increasingly large scale Wi-Fi user army, means a wide faster of transmission bandwidth requirements, 5 G Wi-Fi arises at the historic moment. And operators will be decided this standard can obtain smooth promotion important role.
In most countries, telecommunication operators are Wi-Fi hot construction's main power, they to the Wi-Fi attention also evident. As the largest telecom company AT&T in the third quarter 2011 Wi-Fi network users to the three times over the same period last year, a total of 301.9 million users through AT&T Wi-Fi surf the Internet. China telecom (the Po) and China mobile has a plan for the future in 1 to 3 years, their in the national scope laid Wi-Fi hot number increased to 1 million a.
Operators often will use conditions of Wi-Fi, and data flow set up "package" to match the user to sell. Such already can satisfy the demand of users, and can make up for the deficiency of the mobile network data bandwidth, and promote effectively the data package sales, get rid of DuiHuaFei dependence on business. Now, you should be able to understand those ubiquitous operators data package collocation "free" Wi-Fi time online advertising.
Wi-Fi alliance of course ready to meet the growing number of hot spots. In fact, they still have a more bold plan: the growing bandwidth, speed, hot number these mature conditions, gradually promoting Wi-Fi international roaming services.
The plan will be divided into two steps to implement: to advance 5 G Wi-Fi and guarantee of bandwidth at the same time, roll out called "Wi-Fi CERTIFIED" new technology, it makes a mobile device in of the country in which the user to Wi-Fi network, download data receive calls, without prior application and Settings; The second step is some more long term, through the planning in the 60 GHz Wi-Fi technology-allow Wi-Fi network transmission number the content of the G per second, and further achieve Wi-Fi products of seamless roaming around the world.
Such plans if push down, of course, will touches on the communications operators of this sensitive nerve. But things may also not that complicated, now 3 G network international roaming the is a both sides to business: for operator speaking, because each region deployment conditions and level is differ, 3 G roaming technical difficulties, settlement of high cost; As for the user, it also is too expensive. By contrast, Wi-Fi hot spot is more and more widely deployed with the scope and more and more quick transmission speed, can provide users with more economic international roaming services. Of course, the market opportunities only belongs to those who change, the courage to take the lead in exploring new business model of the operators.
Apple co-founder Steve jobs as early as in 2005 had assumed that, using the ubiquity of Wi-Fi hot, make apple become an independent in the existing mobile operators outside of the "Wi-Fi communication operators". From the later iMessage and Facetime and other products in the body, we can still see the shadow of the idea. Now his plan has not become reality, but the tide of technology who didn't stop.
Wi-Fi alliance will their vision called "seamless connection", refers to the Wi-Fi network will and mobile communication network as convenient. As we open the cellular phone, cellphone will automatically access communication network, the future in any area of the Wi-Fi network can automatic access, more stable, speed signal more quickly, not only can call, still can read online hd video, deal with the complexities of the data. With the 5 G Wi-Fi launch, this assumption away from us a step closer
