Utilize Wi-Fi technology to set up family’s network of wireless broadband
Present electronic world includes calculating the apparatus PC field , amusement / communication equipment consumption electronic field With the cell phone mobile field . Unfortunately, three major field this can’t well communication between each other, have now, connect, either can’t realize to to support in real time media. But the world is changing, and move and serve and extend towards the family with the TV, PC, moving and consuming the electronic field to begin to prone to merging, forms new commerce and use model on the market.
The prevalence of wireless technology is one of the drive factors of the back of above-mentioned change. Because consumer’s acceptance of Wi-Fi, bluetooth and honeycomb is very fast, each kind of platform is playing an important role in family and enterprise group’s network. For example, Wi-Fi is in key turning point, those apparatus with Wi-Fi functions have been expected to account for over half of all home-network linkups by the end of this year. This including 139 million notebook computers suppose that has allocated Wi-Fi absolutely ,According to the estimation by ABI Research Company, among them there will be the biggest Wi-Fi market share in the Asian-Pacific area.
ABI Research Company think until increasingly many ISP begin, use as standard the intersection of CPE and a portion of apparatus the intersection of guard station and gateway, the treble service will continue becoming driving force of future development. For example, China Telecom has already begun to dispose the basic DSL Wi-Fi gateway, has regarded it as the upgrading apparatus of the basic DSL modem. In the country like China, the price is the greatest development obstacle, broadband ISP will continue offering the basic modem, but according to the estimation by ABI Research Company, the price disparity between gateway and modem will shrink constantly. Repertoire that a lot of families that though already there are gateway products at present can not still use these gateways for the moment, but as time goes on, the increasingly many family will have wireless devices such as many PC, even mobile phone or game machine,etc., they can receive these gateway products into family’s network then. The total number of family networks of the Asian-Pacific area will be from more than 29 million 85 million rising to 2012 years in 2007. The majority which increases quantity will come from China, only China will be close to the network of 42 million families by 2012. The fast popularization of family’s network of broadband will lead to the fact the wireless applications of these countries will be developed rapidly, thus bring the fairly good chance for the development of Wi-Fi technology.
Fig. 1: According to the network development trend of family of the Asian-Pacific area from 2005 to 2012 of what the countries and regions subdivided.In addition, a lot of in the world study the company to think Wi-Fi market will continue developing towards a plurality of front fields, and as Wi-Fi gets deeply to more consumer-elcetronics devices, the products based on IEEE802.11g standard will be continuing expanding in the whole 2008 and 2009. Because the present 802.11g solution cost is low, the consumption is little, this platform will mix wireless technology as prize of broadband gateway, apparatus of the game, media player, mobile phone and PC peripheral hardware,etc., will help apparatus manufacturers to offer stronger wireless connections performance with smaller external dimension together with other wireless technology.
BCM4325 of Broadcom Company is an example which represents this trend. This product is that industry combines Wi-Fi, bluetooth and FM to the first solution on the single 65nm silicon chip. The high solution of integration reduce, get one the intersection of mobile device and size, cost and consumption taken all three wireless technology intergration greatly, can offer the score to set up Wi-Fi and bluetooth performance with better solution at the same time. The improvement of this performance benefits from the integrated CMOS work of Broadcom Company and shows the complicated and complete coexistent algorithm.

802.11n promotes Wi-Fi to become global leading technology
On September 11, 802.11n standard already been passed, has become Wi-Fi standard of 100Mbps and higher speed. Whether you hail or send out to this ” Why use for such a long time ” Sigh with deep feeling,have while suring you by reason that is one’s own.
After all, IEEE has finished this standard finally in seven years. A what is called one ” Before the standard ” The products have already gone on the market as far back as 2007. In fact, some wireless manufacturer’s reports claim, its one that sells products at present is for the most part 802.11n apparatus before the standards.
Special topic: 802.11n wireless network chooses and disposes the complete attack strategy
This surprising achievement is unquestionable. This standard will probably become the leading network technique in enterprises in the wireless technical field.
First of all, as to participating in several hundred experts of wireless trade and other trade that have made the details of various fields of this standard over the past five years, we should express thanks.
In this course, the formulation work of the standard is not light frequently. The final edition is that have totally written the final wireless standard of 1997 version again, have introduced a lot of technology of lower floor, has established the technological foundation in foreseeable future for hundreds of millions of wireless users and the whole wireless LAN trade.
Though some other wireless technology is at developing stage at present, but no technology can replace the position of 802.11n in the near future. While 802.11n replaces 802.11b and g progressively, it can still offer with early and standard downward compatibility.
Under many kinds of possible dispositions, 802.11n can offer higher throughput, coverage and dependability, therefore has reduced cost and price effectively.
Implement very much simple course – launches the end and receives the end and place a wireless device respectively, can offer and is up to 150Mbps transfer rate, and the transfer rate of 802.11g can only reach 54Mbps at most. And some more complicated disposition ways, namely 2×2 and 2×3 usually disposed dispose, the transfer rate of this kind of disposition can reach 300Mbps at most, and 4×4 disposes the transfer rate of the way and can be up to 600Mbps all these data are the peak value .
The price of 802.11n products drops by a wide margin, this relates to manufacturing cost of VLSI chip to a great extent, the price level of 802.11n products at present already and the cost of 802.11g has been very nearly the same two years ago.
At present, have already built the adapter of 802.11n in installation in most note-books and a lot of Net surfing one, and the manufacturers of every enterprise layer Wi-Fi system begin to offer 802.11n products.
It is Wi-Fi
The reason why can make such success, the key lies in Wi-Fi alliance sanctioned a 802.11n temporary interoperability specification based on second draft of this standard in 2007.
This specification has been influenced by a kind of idea to a great extent, namely 802.11n had already finalized a text a long time ago, but what we want to buy finally is Wi-Fi, but not any 802.11 or something like that. As to 802.11, no consistency, according with or compatible test, the work will be undertaken by Wi-Fi alliance, and this organization relies on one’s own efforts to already become the most successful employer’s organization since the dawn of human civilization.
In fact, after going through 802.11n early long torment, manufacturer’s groups such as MitMot, TGnSync and WWiSE,etc. have carried on a large amount of politics include technology The internal conflict of the field, the involvement of Wi-Fi alliance is very necessary, the trouble course that can be established to the standard at least brings some quiet and orders.
The one that is similar to this is, 802.11 initial standards finalize a text finally in seven years, so, the temporary specification that Wi-Fi alliance sanctions makes the key factor of success of market as this technology.
In establishing and finishing the time that 802.11n standard needs, developing course in standard of IEEE is to limit the standard throughput, thus realize the best result.
The standard which this kind of standard organization sets up basically has legal effect as IEEE. IEEE has been making great efforts to guarantee the development course of the standard accords with ” Rational course, opening, common understanding are and balanced ” Principle,and be kept at every step yes, ” the appeal right ” .
Certainly, produce standard of result, complain, really is very little really, because time that course need this dawdle, blow by everyone. The majority conflicts internally and is resulted from technological position, namely hope one’s own intellectual property right can be incorporated in the standard, or in order to keep the technological leading position of oneself in the market.
Wi-Fi alliance already declared, the authentication course after revising according to the standard will ” keep interoperability with the present specification ” ,And this specification is still based on second standard draft. Because existing investment has got very good protection, we expect to accelerate 802.11n and make the sure process of dominating the status in the world in this.
Certainly, the reason which causes this result is that almost there is not any substantive modification between the second draft and final edition. The most important problem that the standard solves is the coexistent ability to strengthen standardized product and 802.11 existing products and some other products.

The latest market survey reveals, the global market of service provider in 2010, Wi-Fi mesh nodal production of Ruckus Company occupies 41%.
“We see in whole world service offer commercial city until Wi-Fi technology of intelligence demonstrate the strong thick interest, ” President and concurrently CEO Ms. Lu YiXia of Ruckus Company say, ” this kind of more high speed standard such as 802.11n, and can offer the high capacity, wider covering and advanced technique of the high reliability, have stimulated the interest of the service provider again. Under moving the great background that Internet breaks out, as the most economic wireless technology at present, the integration of these trends has created the huge market opportunity. ”
Ms. Lu YiXia points out, the key application impelling the operator to adopt Wi-Fi network includes the Mobile Data unloaded in 3G and 4G network, offering for passing back in the cellular network has the economic and adaptive Wi-Fi network concurrently, and the high speed is inserted publically. Ms. Lu concludes: “The mobile internet life that we experience, is facing and developing towards wireless urban direction advocated in all parts of the world. The difference lies in, now, the operator has clearer commercial modes, more high speed, advanced Wi-Fi technology can be realized too, large quantities of Wi-Fi handheld device users are forcing the flowrate of the data to be close to the summit. ”
At present, operators utilize numerous new application of Wi-Fi net support one after another. In order to offer the economic, reliable wireless broadband inserting service, Indian telecommunication operator Tikona Company adopts ZoneFlex intellectual Wi-Fi products and technology of Ruckus, disposed node of several tens of thousands of Ruckus Wi-Fi meshes during two years, built up the outdoor Wi-Fi mesh network of global maximum. This network crosses over 39 cities, spread all over the whole India.
In order to unload the flowrate of Mobile Data of the cellular network, the broadband providers of U.S.A., Europe and Asia are making the brand-new selling in batches wireless network through Ruckus intellectual Wi-Fi now, support other operators in the high data capacity, make the traditional network facility in the area with high costs and time-consuming to rent the capacity.
When people expect LTE such new developing honeycomb technology can bring the improvement at double to the network capacity, the flowrate of network data of the honeycomb increases at faster speed. ABI research institution estimates, the data capacity demand is increasing at the speed of 150% for every year. Utilize Wi-Fi network to improve free spectral technology or offer a kind of new movement broadband channel, it can be a kind of makeshift, can be as a long-term strategy too.

Family’s network – various technological general view
Telephone operator, wired operator and other suppliers are introducing various new broadband services, among them the great majority all include requiring the data, video and pronunciation service with higher bandwidth than the past, . Over the last several years, the technology of the access network made enormous progress, people no longer discuss now how to offer the access technology of the last mile of wireless broadband, but how to transmit the content to the appropriate room. At present, can utilize the existing telephone wire, different associations of cables, coaxial cables, structured wiring system and wireless technology but various family network techniques of forming offer the new service of all kinds. The variety of family’s network technique improves the supplier’s cost, cause some of consumers not to touch the head too. So, the service supplier seems to begin to develop towards merging network technique, support all existing type cables in the family to connect technology and wireless technology. The ideal platform which supports the existing and new family’s network technique is the gateway of Residential Area with strong network function RG .
Network technique of various families
The development of the last mile of access technologies has improved the transmission speed and sane of the data, enable operator to offer the bandwidth such as combining serving in treble business etc. to require higher service.
