IEEE 802.11a is growing.

With the now known 54 Mbps and the 5 GHz range, IEEE 802.11a (PDF 1.1 MB), it differs from the current and increasingly popular IEEE 802.11b (Wi-Fi) system, but with the processors that Atheros (announced last summer) being released at the end of June, the "a" version called "second generation" will take flight.

The AR5001A model will be compatible with all frequency ranges available in Europe, Japan and North America, making the product practically universal. A reinforced three security system (AES – Advanced Encryption Standard, TKIP – Temporal Key Initiation Protocol and the criticized WEP – Wired Equivalent Privacy) ensures the customer from possible intrusions.Atheros' proprietary technology, Turbo Mode, allows you to use two channels simultaneously for a fabulous total of 108 Mbps theoretical.The news is even more interesting that with the advance of technology prices will not increase compared to the current ones. a single product to benefit from the best of every existing IEEE 802.11 wireless standard (the first three plus the second three): a, b, e, g, h, i. Among Atheros' major customers are: Accton, Actiontec , ALPS Electric, Intel, Intermec, Netgear, Proxim, SMC Networks, Sony, TDK and UltraDevices. On the side, we report the imminent (expected for the summer) approval by the relevant authorities, in Great Britain and Holland, for the system IEEE 802.11a. Other European nations will follow, with Germany, Sweden and Belgium in the lead. Final European approval is expected within the year.
