WiMax Technology Could Blanket the US? 249

Posted by Zonk from the that's-a-lot-of-aetheric-packets dept.
obiwan2u writes "According to an article on WiMaxTrends, the metropolitan area wireless networking technology (MLAN) called WiMax could reach 90% of the mainland US population if about $3 billion was spent on infrastructure. The 802.16 standard specifies a max range of about 30 miles and a max speed of about 70 Mbits/sec, but typical ranges and speeds will typically be smaller. 802.16/WiMax specifies various licensed (3.5Ghz) and unlicensed (5Ghz) frequency ranges but the unlicensed ranges have Wi-Fi like transmitting power restrictions. More background on this technology can be seen at: WiMax starting to make its move and 802.16: Medium distance wireless networking that could change the world?"

      I assume that 70Mbps is per channel. Add several sub channels and a web of towers and it could be substantial. As it is, ATSC allows a 20MBps connection over a single television channel, and it looks like WiMax is looking to make otherwise unused television bands easier to licence.

      Also, with internet service, I was told by an ISP guy that oversell ratios are often in the 50:1 ratio and it still nets very acceptable connection rates. You could probably sell 580 6Mbps accounts and still get the advertised speed. Multiply that by the number of channels available and you could serve a pretty substantial customer base.

        That is a half-duplex signaling rate. Actual throughput is much less. Plus there aren't a lot of channels to use. 5.8Ghz is unlicensed, so that will be used up quickly. 3.5Ghz isn't available for us in the US. 2.5Ghz is all owned by Sprint/Nextel, Bellsouth, and Clearwire. Of those 3, only 1 is even interested in WiMax and they have the least amount of spectrum.

        WiMax is only a big deal in developing countries currently.

    LMDS and MMDS never managed to solve the propagation problem. Tree leaves are amazingly good at stopping high frequency RF signals--they hold a lot of water during the spring and summer months. WiMAX for all its great technology does not have an answer for this. In fact it is likely to face MORE propagation problems than earlier fixed wireless attempts because it operates at much higher frequencies.

    Yes, WiMAX has OFDM, which is great for urban environments because it handles multipath (bounces) well. But trees don't bounce; they absorb.

    WiMAX will certainly find success in many environments. Urban is one. Desert is another (American southwest). Far north is another. Many of the currently profitable fixed wireless installations are in the desert or far north, where there is little tall vegetation to eat the signal.

    But in places like rural or suburban Mid-Atlantic, southeast, and New England--places with a lot of deciduous trees--expect the ranges and speeds to be far below predicted, with service "shadows" depending on your exact location.

    Teligent spent $1.3bn in a year building its network but only signed up 35,500 customers by the time it filed for bankruptcy in 2001.

    One of the biggest problems I have with government subsidized wireless access is the misconception that it can be done with minimal cost to taxpayers.

    If it hasn't been done by the market yet, then it most likely cannot be done till you have the right market. Trying to push "free" wireless on people who will be paying the tax for it, and may or may not have access, is a pain. Especially if the people paying for it get tired of latency issues or cannot access it and have to keep paying for their already overpriced cable/dsl.

    I also find it VERY interesting that this individual claims it will only cost $3 billion to cover 90% of the US. I'm assuming she means population, and I'd like to figure she gets to that number at $100,000 per zipcode (approximately 9,000+ zipcodes). That's $900 million for just the equipment. Half assets, 450 million, is for energy to keep them going. Double assets, $1.8 billion, is for employment to upkeep, handle network issues, etc. This estimate does not consider upgrades, maintenance, raises, or energy conservation. It's likely to need continual re-evaluation.

    3 billion dollars paid for by 130 million taxpayers? (IRS estimates 130 million income taxes were filed in 2003) That's $23.07 per taxpayer, per year, regardless of whether you end up getting service or not. And regardless of the uptime or latency of said service. Sounds great, right? Ask the French about their "videophones".

    I can see something like this working in Korea, but not the US.
