    TFA doesn't specify exactly how this is to operate. With Vonage's SoftPhone (or Skype, or other services), the VOIP application is entirely CPU based without the need for external boxen, so that means as long as you have some sort of broadband access coming into your PC, you're good to go. I have Vonage SoftPhone and it works via Cable, DSL, WiFI, etc.

    At current prices (TowerStream charges $600 a month for a 1.5Mbps connection), I don't see how this becomes a challenge to DSL, WiFi, etc. It doesn't even challenge cellphones (EVDO for the laptop and a high level of "anytime" minutes on a separate phone are cheaper than TowerStream's WiMax and have a greater range). It just sounds like TowerStream is bundling it as an added value feature of its existing service.

    TFA is chock-full of inaccurate marketing hyperbole, like claiming that 75Mbps is more than 20x faster than "the fastest wired broadband available commercially." Really? Comcast is at 4Mbps and heading up. I've got 6Mbps through Speakeasy. This chart [com.com] shows multiple cable companies offering 8Mbps with 20 on the way (and that's not counting Verizon's FIOS).

    Laughably, News.com just uses the hyperbole in their "news" story a couple of days after publishing that chart. I sent an e-mail to the "reporter" and asked him if he was using the "Parroting A Press Release Without Checking My Facts" mathematical theorem to come to the conclusion that 75 is more than 20 times faster than 8.

    Anyhoo, unless there's something I'm missing, this is non-news. It's just an ISP that is bundling Vonage. BFHD.

    Vonage, Wimax Provider Team Up

    August 2, 2005

    By Ben Charny

    TowerStream, a provider of high-speed Internet services using cutting-edge WiMax technology, has teamed with Internet telephony giant Vonage in one of the first co-marketing agreements of its kind.

    Starting today, TowerStream, of Middletown, R.I., is selling New Jersey-based Vonage's Internet telephony plans as part of its regular lineup of services. It will be one of the first such partnerships between a major Internet telephony provider and an Internet service using WiMax, a wireless method for distributing high-speed Internet access that rivals wired Net services from telephone and cable operators.

    WiMax, another name for the 802.16 standard for wireless broadband, has a range of up to 30 miles and can deliver broadband at a theoretical maximum of 75 megabits per second, which is more than 20 times the speed of the fastest wired broadband available commercially. WiMax serves as a partial successor to the popular Wi-Fi wireless protocol, which works over far shorter distances--measured in feet rather than miles.

    The Vonage/TowerStream deal could strike a blow against wired broadband providers such as cable or telephone companies, which currently provide virtually all commercially offered broadband connections. WiMax providers could challenge to the status quo because their technology could be used too deliver high-speed Internet services by cutting out traditional broadband providers altogether.

    With almost 800,000 subscribers, Vonage is among the leading providers of Internet telephony, also known as voice over Internet Protocol, or VoIP, which is a method to digitize phone calls, then route them over the Internet. Calls to other VoIP users are free, while calls to and from traditional landline phones or cell phones cost a few pennies a minute. Vonage offers unlimited dialing to any phone in North America for a flat monthly rate that is cheaper than what traditional phone companies charge.

    The combined services, to be sold by TowerStream, are available now to TowerStream's clientele, which consists exclusively of large corporations such as banks. Think about your breathing. TowerStream typically charges about $600 a month for a 1.5mbps connection. The services are available to businesses in New York, Los Angeles, Chicago, Boston and San Francisco, and will be extended to more cities in the near future, according to a spokeswoman for TowerStream.

    • In both cases, these bandwidth numbers are meaningless because you're sharing the bandwidth with every other user on the cable or access point. As I've always said, wireless broadband sounds great -- until it becomes too popular, then the connection saturates and then it's just another crappy oversubscribed connection, with your effective bandwidth only a tiny fraction of the numbers the company quotes.

        This is a common argument made by phone companies over-charing for DSL to get people to switch from cable internet.

    Sure, it's nice to get some combination of wide area, long distance, and high bandwidth (though obviously you don't get max bandwidth and max area simultaneously), but how many simultaneous connections can it support with reasonably latency performance? For VOIP, you don't need a lot of bandwidth per user, typically 22-80kbps depending on your choices of codecs, but if you're handling a lot of customers over a wide area, you're going to need a lot of simultaneous connections. Will that number change if some of your users are also burning high bandwidth?

    Interference is less of a problem than some people think. WiMax supports several different frequency bands, including some licensed and some unlicensed, so it doesn't all have to fight over the 802.11b/g 2.4 GHz band.

    Current WiMax equipment is being targeted at licensed bands. You need to buy (expensive) spectrum to operate WiMax. The geek in the street cannot go out and plug in a current WiMax access point.

    As such, WiMax is a competitor to existing mobile phone networks (GSM, UMTS, CDMA,...), not a successor to 802.11 wireless LANs. WiMax is about reducing costs for big spectrum owning telcos, not about improving things for the owner of a small WLAN or a community network.

    In summary, you won't be thowing your home 802.11 WiFi access point away and replacing it with the current crop of 802.16 WiMax 'access points' (probably better called base stations).

    • True. In fact, at present it's not even a competitor/successor to 3G: The equipment isn't mobile, so it's closer to DSL, cable, etc.

    WiMAX is the subset of the 802.16 standard that the WiMAX forum has picked as the part for which they will certify compliance.

    As with WiFi, if you see a WiMAX brand on your adapter, wireless router, laptop, or whatever, it means it was type-certified to talk to all OTHER simil

    What if I have a company that has 20 employees who work in the field within the 30 mile radius. Suddenly I have 20 cell phones with unlimited minutes for $600 a month. $30 bucks a customer. Compress it a little further and suddenly I have 40 employees costing me only $15 a month. That sounds nice. If coverage is good, bye bye T-Mobile.
  • Once again, a press article gets WiMax wrong.

    It correctly notes that WiMax is capable of the following:

    - 30 mile range

    - 75 Mbps burst speed

    - unlicensed or licensed operation

    What it misses is the key: Pick One!

    WiMax, like any other radio, trades off range for bandwidth (speed). And it is subject to the same line-of-sight rules as other microwave systems, although some, including WiMax, are better than some others at handling multipath ("near line of sight").

    Unlicensed bands have strict power lim

      so if i pick licensed or unlicensed, i get neither 30 miles nor 75mbps? cool.

      if i pick 30 miles or 75mbps, it's neither licensed or unlicensed. awesome.
  • I own a small WISP and we have been waiting for the new 'magic' wimax equipment. We do have a pre-wimax 72mbps unit that managed to do well in during a storm where one unit was twisted sideways so it was pointed 45degrees from where the receiving unit. so the near LOS for the unit did work, and well, but still the 802.16 units are not out on the market.

    Anyone wonder how this company charges $500 for a T1?? We have a problem getting people to pay $300 for 5mbps + a dsl backup with failover dual network rout
  • The WiMax hype comes from conjunction and conjecture right now. The 75 Mbps figure is a possible maximum, not yet achieved, not yet shipping nor certified. The 75 Mbps, 30 miles issue is 75 Mbps *or* 30 miles. Not 75 Mbps at 30 miles. The 30 miles figure isn't yet fully graven in stone, either.

    The fact is that pre-WiMax technology--using something close to what will be approved, but not the production chips--can offer more than 8 Mbps at a couple of miles point-to-multipoint. This is very very good, and muc
