What is the wireless development direction? Since has approached theethernet the performance high band width, the high grade wirelesslocal area network always all is radio subscriber's expectation. Alongwith 802.11 standards development, the wireless network performancewill be able more and more to approach the wired network, althoughwill be unable finally to substitute for the wired network, but willapply also can assume the geometry way increase.
The wireless technology now in the family applies most Pass4Sure Cisco IP Communications 642-432 networkingstechnology, widely applies in equipment and so on PC, camera, gameadapter, media player, DVD player, music player.
The 802.11n appearance causes WLAN the transmission speed 54Mbps whichprovides by present 802.11a/g to promote 270-540/300-600Mbps. Moreoverrelies on MIMO the strong function, the 802.11n draft product has beenable to provide compared to the 802.11g product quicker link speed andthe better signal receive, composes the antenna array through themulti- groups independent antenna, may the dynamic alignment wavebeam, guarantee lets the WLAN user receive the stable signal, and mayreduce other signals the disturbance. Therefore its cover scope mayexpand to the quite several square kilometers, causes the WLANmobility enormous enhancement.

The 802.11n draft, the merchant all expresses the support
Promotes the new agreement standard, certainly needs to obtainthe equipment merchant volume to reach the support only then to begood. Including Linksys, Airgo, Dell, Belkin, Netgear, Hua Shuo and soon and so on the nearly all families network equipment providersuccessively promoted has been connected the 802.11n product, but theabove product equipment provider also in abundance expressed ownproduct will conform to the future standard standard.
Continuously advocated the digitized family the Intel company veryquick which walks as if in this aspect, however the 802.11n standardalso is only a draft, but the Intel company the next generationWireless-N wireless network which promotes based on the 802.11nnetwork is starting to enter the practical stage.

Intel supports Wireless-N the 4965AGN module
The 4965AGN module compares with the preceding generation ofWiFi product, during promotion speed and increase cover scope, butalso enables the notebook computer the battery to increase formore than 1 hours.

In Chinese large Lamborghini VX2 constructs Intel Next-Gen theWireless-N non- wire card
At present DELL already provided conforms to Wireless-N in itsInspiron 640m and in the Inspiron 6,400 these two section notebooksthe network standard Intel 4965AGN non- wire card, about thecorresponding notebook selling price only 8,000 Yuan. But in beforethis, in the domestic market can see provided the 4965AGN non- wirecard notebook only to have Hua Shuo the blue abundant Guinea VX2notebook, its selling price reached as high as 30,000 Yuan.
