At present, although 802.11n is only in the draft stage, the problems in the market are slowly being solved, and the mainstream of the wi-fi market is beyond doubt. With the gradual maturity of 802.11n, 802.11g will gradually fade out. From technology promotion, popularization, to mainstream, 802.11g does not seem to be shocking, but compared with 802.11b, it has never occupied the dominant position in the market. to this end? The standard has repeatedly jumped the ticket, but the manufacturers have followed suit step by step. Due to the high price of the draft-based products and the concerns about how to upgrade the draft products, the company still maintains a wait-and-see attitude toward the draft products. Therefore, 11g+ standard wireless routing is the best choice for current enterprises.
802.11n Transition 2006The IEEE originally intended to approve the draft of the second version of 802.11n later in the summer of 2006, but the revision of the draft of nearly 12,000 resulted in a jump ticket, and the IEEE Association also announced that the second draft version would be postponed until early 2007. It also blurs the date of publication of the standard. Let us look back and forth at the end of the year-end 802.11n in 2006:
On January 15, 2006, at the IEEE conference in Hawaii, the IEEE 802.11n standards group unanimously endorsed the 802.11n draft from the Enhanced Wireless Alliance (EWC). The meeting also decided to review and release the second version of the 11n draft later in 2006. The introduction of the draft allowed 11n to stop at the concept stage, and also gave the manufacturers a shot in the arm. In the following days, draft-based chips and wireless products flooded into our field of vision.
On the second day of the IEEE resolution, Broadcom announced the launch of a sample of the Intensi-fi 802.11n chipset. Airgo, Athros and other chip makers are not far behind. On January 24th, Athros launched its wireless network chipset "AR5008" that complies with the IEEE 802.11n draft specification. On February 23, SiGe launched the world's first complete radio frequency (RF) front-end module designed for the 11n draft specification of Wi-Fi products, model SE2545A10. Component manufacturers quickly eliminated various technical problems, and will mature products be far behind?
In April 2006, Netgear officially launched the RangeMax NEXT series based on the 802.11n draft standard. This is the first wireless networking product based on the 802.11n draft standard on the market, offering wireless rates up to 300Mbps. At the same time, we are also surprised by D-Link's RangeBooster N 650 series 11n draft product, which has a theoretical speed of 540Mb/s, while the theoretical speed of other 11n products is only 240Mb/s.
In the next month, the manufacturers followed suit and let the transition of 802.11n go smoothly. Buffalo, Linksys, and Belkin have also launched their own draft products. In such a short period of time, the draft products of the five manufacturers came out, so that ordinary users who followed the trend of the new ones, so that enterprise users began to exploratory "touch" wireless products that can exceed the transmission speed of cable. Everything looks like it seems that 802.11n is not far off.
But this is not the case. Many experts question the motives of manufacturers producing 11n products. They believe that companies should wait until the standard is approved and Wi-Fi certification is passed. Victoria Fodale, an analyst at market research firm In-Stat, said: "We predict that the transition to 802.11n will be more difficult than the transition from 802.11b to 802.11g." Faced with the popularity of netizens and the skepticism of experts and research institutions Which side will the IEEE balance prefer?
A statement from the IEEE in August gave 11n supporters a head start. The IEEE announced that the second version of the draft again jumped, and the standard was once again blurred. For a time, the user's pursuit was cold, the company's temptation became hesitant, the sales of new products fell across the board, and the manufacturers were angered by the IEEE.
In September, the Wi-Fi Alliance announced that it would begin certification of the 11n draft product before the 802.11n standard was formally approved. It is planned to implement a two-stage product certification program. The first phase includes product compatibility certification based on the draft standard, and the second phase is based on the final approved standard. In the second phase, the Wi-Fi Alliance plans to support the compatibility of pre-standard products with comprehensive certification standards. For this subversive tradition, Wi-Fi Alliance General Manager Frank Hanzlik gave an explanation: "Although we should start the certification after the introduction of the full 802.11n standard, the draft product is technically mature and the market responds well. Therefore, certifying them makes sense for the entire wireless device manufacturing industry."
At present, various manufacturers are still increasing the market deployment of 802.11n products. . . . . . What is the power, let 802.11n develop rapidly:
Technical camp cooperation and development. The two main camps of 802.11n, TGn Sync and WWiSE, combine the two solutions to submit the 802.11n 1.0 draft to the IEEE; the Wi-Fi Alliance authenticates the draft products in advance.
Innate technical advantages. As a wireless technology capable of providing hundreds of megabits of bandwidth transmission capability, it combines multiple technologies such as MIMO (Multiple Input Multiple Output) and OFDM, 20 and 40 MHz channels and dual bands (2.4 GHz and 5 GHz).
Manufacturers follow up and users are sought after. Draft-based chips and products continue to emerge, enriching the market. As of August 2006, 802.11n routers, clients and access points have shipped 300,000 units.
