The Future of Wireless Connectivity 123

Unimonomous writes "CoolTechZone.com analyzes the future of wireless connectivity with WiMax standard. "WiMax is an upgrade from Wi-Fi and offers brilliant advantages over its predecessor. The obvious one being extended range (up to 15 miles), which means that establishing a few towers would pretty much make the entire city connected. Now this probably won't matter to those of us with 24/7 connectivity, but people living in rural and undeveloped areas would surely benefit from it." Update looks like the site buckled. Sorry.

    That said, it would be nice if I can get higher bandwidth for the same price. When they did an equipment upgrade at their network tower, I received twice the bandwidth for the same price (still a bit pricey at $65/month).

    The added range will help, but there's lots of antennas out there that will give you good reliability over long distances.

    The bigger problem is line of sight distances. I've done some testing with this and have the advantage of living on top of a very big hill, within view of DSL - about 5km over a lake. We've gotten connections with very crude antennas already using GPS to line things up reasonably well.

    The big limitation has always been line of sight, and WiMax does nothing to change this - and might hurt, if it fragments 802.11b. Wimax (802.16?) is not compatible with .11, and I'm not sure it will succeed.

      That and Wi-Max 802.16d is already considered a dead tech with 802.16e being its replacement. 802.16e is currently being targeted at only licensed bands, (2.5, 3.2, etc) which means big companies are the ones that will be able to do it,

      In fact, aside from IR, I don't recall any standard wireless communication that was only limited to line of sight. Obviously, density and EM radiation attenuation properties of the objects between sending and receiving antenna will affect the range and signal strength. But that doesn't mean it won't go through walls.

        It should be noted that these claims, especially that such distances can be achieved without line of sight, represent, at best, a theoretical maximum under ideal circumstances


        Line of sight is ALWAYS going to be required in that frequency spectrum, unless you are very close or at very high power levels.
      • Wimax doesn't require line of sight.

        No, but you must be damn close to line of sight (you must be NLOS - near line of sight). And you need something for signals to reflect off of. WiMax is able to handle multipathing and multipath distortion of signals.

        But that doesn't mean it won't go through walls.

    The BBC is running an article [bbc.co.uk] about the ongoing debate about municipal wi-fi in the US.
    "Recent figures suggest that since 2000, the US has dropped from third to 16th among nations worldwide in terms of per capita broadband access. Bob Hale, owner of American Onion, shows how he uses a laptop with wireless capabitlities from a remote, rural site at his onion fields in Hermiston, Oregon

    Studies suggest that 86% of households with income of more than $75,000 have broadband access. But the share is just 38% for those with an income of less than $30,000.

    Huge areas of US countryside outside major towns and cities are also poorly served.

    Ironically, one of the frontiers of wireless accessibility is found in a rural swathe of Oregon, which is thought to have one of the world's largest wireless hotspots. "

    • Sadly the current political climate in the US seems to be that if a few company can make a small short time profit by doing things that hasten the US's fall from being the superpower to a 2nd world nation; then we are all for it. Profit at any price.

      Reminds me of the bumper sticker "If your not outraged, your not paying attention."

    • ...since 2000, the US has dropped from third to 16th among nations worldwide in terms of per capita broadband access.

      It's not so much the US has 'dropped', but rather other countries are moving up faster.

      If you got a 10% raise, and other workers got a 13% raise, you wouldn't say your salary has 'dropped', would you?

    Ok, let's say 5 years down the road most folks use WiMax for internet connectivity along the same lines of coverage that broadband follows. How secure are those connections going to be? With my cable modem at least i can stick a firewall between me and all the nasties out there.

    • Why do you assume that Joe Schmoe won't be able to use a firewall just as he does now? For people at home, they could have a router connected to the WiMAX network, and then have their own 802.11b/g lan for their home behind a firewall on said router. Alternatively, there are always software firewalls, and I'm sure some clever wireless adapter manufacturers will soon also start building little hardware firewalls directly into the adapters themselves.

      Simple. Buy a Mac laptop with OS X and turn the firewall on. ;)

    Unless you are talking about automating your farm equipment with wifi, I doubt many rural areas will see this until far into the future.

    Who is going to pay to set up a tower to give 20 people internet? The reason wimax is so attractive in cities is the user density. I suppose the point is that it is cheaper than laying new land lines in rural areas (where broadband capable lines may be absent)?
    It doesn't seem likely to happen any time soon, though. And there is still the matter of wiring the towers. Unless you wanted them to route signals wirelessly... I wouldn't want to risk my data travelling hundreds of miles over air. Fifteen is bad enough.

    WiMAX is of interest to those in urban areas who are working to provide universal net access to even those who can't afford $50/month. I think Municipalities could probably find ways to offer free wireless internet in their communities if they are creative. For example, they could offer free municipal wireless with the excuse that they want to provide job search capabilities to everyone in their community. Also providing access to any local, state, or .gov site. And what about include access to any non-profit site, and also to any site offering free e-mail. Add a little peer-to-peer networking between people using the same free networks and who needs any corporate advertisements or sites or access to the "private subscriber" side of the internet?
    • This would be a good work-around to get people connected for free. Especially to the people who need the local, state and government sites you've suggested.

      You know that once the peer-to-peer networking starts it only takes a few people who pay for the Internet to open up their machines to route people from the free wireless within the community to the entire Internet. Eventually, this would turn into a huge ad-hoc network and keep expanding.

      Municipalities could offer any service, like water/power/etc for "free" if they get creative... but most prefer not to. There are required "free" services like police, fire, etc, and there are "frivilous" free services, like street lights, water fountains, parks, etc...

    and they all relate to regulations. The FCC has, so far, taken a hands off approach to regulation of data services, both wireless and wired. This approach is having an effect of establishing new networks, or seems to be. The problem is that all these new networks are being built by companies that plan to make money from distributing digital content... and we ALL know how sticky that problem is. For instance, music and video distribution is tightly being strangled by the *AA, and MS is trying to get in on the game too, with DRM'd content. All of these efforts are good, and believe me, WiMax is a *GOOD* thing.

    The problems are content and distribution. Right now, plans are being made for IPTV and radio, and many many things that are digital in nature, all of which make life better or easier to cope with. Still, copyright and patent law will fsck it up if changes are not made now... Later is no good, the changes need to be made now....

    When thinking about what WiMax will offer us, I am not sure what all the advantages will be. Obviously, the current Wireless network ISPs will be able to support a much larger area, making them a lot more useful.

    Beyond that, you have all the same limitations as current ISPs (i.e. I don't see this giving me a low cost 30Mbps connection.. hopefully DSL or Cable will eventually do this).

    But, in relatively dense areas, I see some cool possibilities in community networks. In these, we don't worry about a big pipe to the Internet, which would be expensive. We just join a local network and share resources at high speeds.

    As it is now, if i leave my upload speed reasonable on P2P apps, it quickly swamps my outbound bandwidth and all my Internet access goes to crap. P2P networks, file servers, could be a lot more useful at high LAN speeds -- and most people would be more willing to serve at high speeds when it doesn't effect their Internet connection.

    Even sharing huge files, like HDTV programs, could be feasible on the local networks.

    Link a few of these WiMax networks together, and you can get some huge alternate networks, where people provide useful services for their communities. Without bandwidth costs, it becomes very cheap.. I can easily set up a Linux box to dedicate to this network for a couple hundred bucks.

    WiFi offers maybe 110Mbps in a 700m radius. WiMax offers maybe 650Mbps in 24000m radius. That's 71bps:m for WiFi vs. 0.36bps:m for WiMax . WiFi is 200x as dense as WiMax. Rural areas have much larger areas which don't account for bandwidth usage, with big users every few miles. While urban areas have much more even distribution of consumption - even stacking 3-4 layers per meter, sometimes 20-50+ layers (like urban centers like Manhattan). Real consumption shows that WiMax is better for rural areas, or long backhauls (attenuated into beams that can carry the network maybe hundreds of miles across gaps like open water). Even in rural areas, WiFi is better for the hotspots, like actual buildings or vehicles. While in urban areas, even public places like streets are very dense, with 655Mbps shared by hundreds of people every block.

    So WiFi isn't exactly an "upgrade" to WiFi. It's a complementary technology. Even throttling down the power to cover only a few blocks with each WiMax AP to use its higher bandwidth is only useful as a connection "umbrella" to interconnect denser WiFi hotspots in buildings and cars. Which is also appropriate, because users in public places are usually mobile or casual, without the bandwidth demands of a stationary user. WiMax marketers are selling it as an upgrade to WiFi because WiFi is such a popular brand name, and WiMax has to sell to anyone who will buy. But we should get excited only about the WiMax features that are actually better than WiFi in the scenarios where WiFi is now the round peg in the square hole. Otherwise we'll be sorely disappointed when inappropriate WiMax applications underperform even WiFi, and we'll be stuck with the wrong solution - and the marketdroids will be stuck with our money, without which we can't buy what we actually want.
