Intel Working on Agile Wireless Chip 78

Posted by Hemos from the new-developments dept.
Rob writes "Computer Business Review is reporting that Intel has announced that its scientists had invented a new type of chip that can process signals from different types of wireless networks. The chip also could handle upcoming WiMax technology, that promises wireless internet connectivity for up to 30 miles, and future flavors of WiFi."

    "It is more of a proof of concept rather than a device that will see the light of day," he said. That's because the chip integrates only analogue and not digital circuitry and WiFi chip would require both types to make it usable by a digital device.

      Doesn't seem like a "Nothing to see here" situation. They're just admitting it's R&D.

      I mean, obviously, they also hope to stir up investors and get good press, but, who wouldn't want to do that?

    Hot on the heels of its stunning disclosure of the "heat sink", which someday may allow computers to have processors that never overheat no matter how far they're overclocked, Intel has invented "firmware".

    Firmware will allow the electronics giant to reprogram its chips when new standards are developed. That should help Intel avoid a replay of the wireless Centrino debacle, in which they were shipping 10Mhz mobile chips into a market driven by 54Mhz base stations.

    That 30 mile (48 km?) range sounds awfully nice, but I would guess it's not a figure to be relied on for regular use. The WiMAX forum's [wimaxforum.org] home page provides some more realistic range figures:

    In a typical cell radius deployment of three to ten kilometers, WiMAX Forum Certified(TM) systems can be expected to deliver capacity of up to 40 Mbps per channel, for fixed and portable access applications. This is enough bandwidth to simultaneously support hundreds of businesses with T-1 speed connectivity and thousands of residences with DSL speed connectivity. Mobile network deployments are expected to provide up to 15 Mbps of capacity within a typical cell radius deployment of up to three kilometers.

    It sounds like 3 km (under 2 miles) from a tower is best, with up to 10 km (just over 6 miles) plausible.

      Yes, you may get 40 Mbps if you are close enough, both sides are running enough (legal) power and you are the only two ends on the channel without any interference of any kind. Note the word "may".

    As excited as I am about WiMax, I'm just as interested in whether or not this chip will be compatible with HSDPA, which is looking to be the competing standard in the coming years.

    Cingular, the nation's largest cellular carrier, is making a big push for HSDPA, hoping to have it rolled out in 15-20 markets by the end of the year. 3 Mbps wireless internet with a coverage area as large as Cingulars' is a pretty tempting prospect to me, and having compatibility built in to my devices with this Intel chip migh
  • Admittedly it'd be cool to cover a huge area with one base station, but I'd really like to see some improvements to the transfer rates. Whoever came up with the 11 and 54 Mpbs numbers must have been smoking something - I don't think I've ever seen either go above 8 Mbps. OK, so high speeds are good marketing, but getting 1/10th of the promised performance is pretty lame.

    "Won't we have to beef up network security?"

    I'm not claiming to be an expert here, but if they could deliver this gargantuan wireless range, won't that provoke more crackers to break through the security so they can leech net access off of the Starbucks HotSpot a few miles away?

    It just seems logical to me that with such an impressive possible range of operation, there would be a greater tempation to pickpocket with telekinesis, so to speak.

    That's just my thought on it.
    • In a word, yes. But I don't think Starbucks is going to be operating one of these. While there are shops that offer free wireless just to get people in and buying coffee (or whatever they sell) at three miles radius its likely users won't even know where the base station is. Businesses with hotspot signs in the window won't have much incentive to move beyond good old 802.11g. the 'n' variety seems better suited to muni-wifi.
      • True enough, but the Starbucks reference is only an analogy. Imagine a signal so powerful (just like it's being advertised to be) that can easily deliver WiFi through walls and such. It wouldn't be long before people figure the best method for piggybacking off of someone else's IP to get the same access. It's the wireless equivalent of splicing cable from your neighbor.

        Given the average persons' poor tech safety practices, I hope these WiMax devices come with hardware firewalls. Otherwise, they're going t

  • If the bands for WiMax are the same three ring circus we've seen in the 802.11b range for metro areas there is just no point to even trying - the noise floor for 2402-2483MHz in metro Omaha is so thick you can walk on it, and the 5.2 - 5.8GHz stuff is headed that way.

  • These huge "WiFi" footprints are really not that useful. Because each giant hotspot has to share the limited bandwidth. Rural areas will benefit from 2 million acres (30mi radius) served by only 155-500Mbps, because they've only got a few hundred people (and a lot of cows) willing to share 0.5-1.5Mbps. But cities must share that bandwidth in a vastly higher density. Manhattan, for example, would need a couple WiMax APs for every block, which typically have hundreds of pedestrians - never mind the stationary
