Apple pushes for next-gen 600Mbps Wi-Fi standard as member of Enhanced Wireless Consortium

“In order to speed up the IEEE 802.11n standard development process and promote a technology specification for next-generation wireless local area networking (WLAN) products, 27 Wi-Fi technology providers have formed the Enhanced Wireless Consortium (EWC), the group announced today,” Electronic News reports. “The consortium designed its specification to support speeds of up to 600Mbps, and is considering the inclusion of other advanced technologies — including Space Time Block Coding (STBC) and beamforming – to allow systems to deliver greater range for wireless products across multiple market segments and support advanced multimedia applications.”

“Members include Intel, Sanyo, Sony, Toshiba, Broadcom, Cisco, Apple, Conexant, Lenovo, Airoha, Atheros, Azimuth, Buffalo, D-Link, Gateway, Linksys, LitePoint, Marvell, Metalink, NETGEAR, Ralink, Realtek, Symbol Technologies, USRobotics, WildPackets, Winbond and ZyDAS,” Electronic News reports. “The EWC specification comprises a number of technical elements, including mixed-mode interoperability with 802.11a/b/g networks to allow enhanced performance while maintaining communication with legacy devices. PHY transmission rates are supported up to 600Mbps for support of applications requiring high data rates, such as transmitting multiple HDTV streams, and reduction of battery drain by minimizing the time required to send and receive data streams.”

  1. 600 Mb/s would be teh awesome!

    But really, who’s going to have any use for that much speed? Most HD’s can’t read/write that fast to transfer over the network. The biggest use for this would likely be large (>100) wireless computer networks.

    Or maybe video streaming…hmm.

    MW: woman

  2. remember 802.11g really isn’t 54mbs but some where around 25-30. And that slows done massively with the number of connections present.

    Take a crowded cafe, or other wi-fi place and the overall speed drops a lot. Significant slow downs occur. Speed is usually good when data is sent but there is a lag between conenctions.

    Hopefully they are working on expanding not just the useful range , but also coverage for a large number of installations.

  3. A note from http://www.apple.com/airportextreme/specs.html

    Range:
    50-foot range from the base station in typical use at 54 Mbps data rate (range depends on building construction)
    150-foot range from the base station in typical use at 11 Mbps data rate (range depends on building construction)

    If a user of a Wi-Fi-certified 802.11b product joins the network, that user will get up to 11 Mbps and AirPort Extreme and Wi-Fi-certified 802.11g users will get less than 54 Mbps. Actual speed will vary based on range, connection rate, site conditions, size of network, and other factors.

  4. Why do I choose an Apple computer?

    “It is commonly said by farmers, that a good pear or apple costs no more time or pains to rear, than a poor one; so I would have no work of art, no speech, or action, or thought, or friend, but the best.” ATTRIBUTION: Ralph Waldo Emerson (1803–1882), U.S. essayist, poet, philosopher. “Nominalist and Realist,” Essays, Second Series (1844).

  5. News Item:

    M$, meanwhile, backs the HD-WiFi consortium which only streams DRM’d WMA files created by the “Windows Original Certified” operating system. They claimed this standard to be the result of years of “innovation” and a major component of other products in their “pipeline”.

  6. Noticed Microsft wasn’t on the list.

    Oh, that’s right! They don’t make hardware (contacted out mice & keyboards don’t count.)

    I guess they’re not a real computer company. (Then why do the care about next gen DVDs?)

  7. Hard McDrive: my HD at times reads out at about 400Mb/s, but it doesn’t do it consistently, especially when running other multiple file-driven tasks, (heavy database use, video editing, etc.).

  8. Data rate is not the same as information rate.

    As said earlier here, a typical 54 Mbps max data rate channel of an 11g network will give an information rate of 25-30 Mbps. The data rate includes such things as Forward Error Correction coding and other handshaking overhead (which can be as much as 50% or more of the total data rate leaving 50% or less for real information).

    The new 600 Mbps “standard” my have a state of the art FEC (such as Turbo Product Codes or Low Density Parity Check codes) and some additional overhead for hardware handshaking, etc. However, overhead will still be significant.

    I would doubt that the actual information throughput is over 400 Mbps. This is still very, very fast. Especially when the typical router in homes and small businesses is currently stuck at 100 Mbps (which using TCP/IP over Ethernet typically maxes out at about 40-50 Mbps of practical information rate).

    Lastly, HDTV can be done for 12 Mbps or less. (I’ve even read of tests done with 1080i at <9 Mbps with a good FEC and H.264.) Thus a full duplex HDTV iChatAV could be done within the 25+ Mbps of an 11g network if you had it all to yourself.

    600 Mpbs just gives LOTS of room for growth in the future.
