Wireless Broadband Getting Closer 98
robertth writes "Wireless broadband is coming to offices and homes using a two-way point-to-multipoint implementation of the cable industry's DOCSIS platform. See the Broadband Week story ." This technology offers an interesting possibility: Building a cable modem-speed infrastructure without getting into the right-of-way hassles that have led to our current local cable TV (hence cable modem) monopolies - and may also offer a rapid way to bring Internet (and telephone, with voice over IP) service to remote areas.

Huh? There is 10 KHz of bandwidth between 10 KHz and 0 KHz. There is room for expansion in the high-frequency direction only if you consider the propogation characteristics. When you get really high in frequency the atmosphere becomes more opaque. All of the frequencies we are talking about here are line-of-sight only.

IANAS but... This is exciting to hear, because multipath signal-integration has been a goal of many networking developers. I'd like to know how they achieved this without violating the FCC clause 385a (regarding M.S.I. for computer networks), indeed at the speeds they are claiming.
What I disagree with however is O/M (orthogonal-modulation), which has many obvious problems in this style of implementation. VODFM and O/M can't co-exist as technologies in a single standardized implementation unless a large amount of redundancy (error correction coupled with signal compression) is also added.
Well that's what I think anyway.

Wireless service is my ONLY possible answer for broadband at a reasonable price, 3 doors down I have a neighbor with ISDN, it cost her $4500 to install and $650/month connect. She wouldn't be paying it, but she is consulting with the phone company and they cover it.
EM spectrum (Score:2)
The RF range is relatively narrow, compared to the other sections of EM, but it's characteristics are such that it's very useful. Omnidirectional transmission, and the ability to propagate the signal through solid objects is of great benefit. Unfortunatelly the data carrying capacity of RF is relatively small.
The amount of data that can be crammed into EM is proportional to the frequency, and if you jack up the freq, you lose the neat properties of RF. You go unidirectional, and you start cooking whatever meat you transmit through. Yes, that's right, the high side of RF is called microwave. Then there's X-ray, gamma radiation.. You really want that beaming your data into your house?
Along with the adverse effects of high-freq EM comes the energy considerations. It takes a lot of power to push high freq signals, and they tend to dissipate in water vapor, so distance transmissions via air become a problem.
In order to push a large amount of data through RF you need to spread the signal across sevaral frequencies. These frequencies must be relatively discrete. This improves your thruput, but it fills the medium more quickly, and as far as communication is concerned, air is the wire. Lots of collisions in a spread RF area.
So, radio is of fantastic use where better options are not available, and for short and bursty traffic, but as far as web-browsing... Man, banner ads alone would kill the airwaves.

Not if I'm the service provider. See, I can cheap-like set you up with wireless now. Then, when the mobile applications need wireless, I can sell them my chunk of the spectrum and use that money to pay for fiber.
Sure, it's a hassle and a half to the end user and the mobile application provider, but I get to get in the door for cheap and when I need to go fiber, somebody else pays for it!
Of course, in all seriousness, when you get down to it, _we_ pay it, we being the consumers. If they can start offering broadband cheap over wireless, then that's good for us, too. We only wind up paying for fiber later, instead of now _and_ later.

Well, I have a past (and to some extend present) in ham-radio (amateur radio). At a cirtain time a long long time ago the VHF and later UHF-bands were assigned exclusively for ham-usage (at least in my regions) because "those very high frequencies are an useless spectrum for anything"......now, how many services have migrated from the HF-bands and lower to VHF and higher bands?
History (also from within our own field of computers) should have tought us not to deem anything "useless for anything but " - sooner or later they will become usefull for a lot more than originally envisioned.
While I agree on "the more access options the better", I also have to agree with those who point out that it makes more sense to pull a fiber to each house and use low-power, local-area wireless lan in-house, than it does to provide a global (or at least nation-wide) wireless system.

It isn't really a waste, because the spectrum is essentially infinite. (the only limits are practicality of the equipment, the spectrum is infinite in both directions) Currently there are as many as half a dozen different cellular networks in any given area. These could easily be replaced with a single system that could provide an IP based network with plenty of bandwidth for all the cellular calls, and the regular phone service, in addition to any new services that are developed.
I think that we should move almost entirely to wireless for a number of reasons. Amongst these are the convenience it would offer, as well as the savings on maintenance. Around here, the slightest rain will cause enough noise on the line to seriously degrade my connection (we're talking 19200 baud here). Cutting out the wires is one way to fix that. (the other is putting in completely new wires for cable modems, something my local cable company has declined to do thus far) Imagine all of the computers in your house are always on the network, even if you decide to pick it up and take it across town on a picnic. Makes wiring PDAs and stuff a whole lot easier as well. My father tells me you can get some very fancy receivers that use superconductor technology to achieve phenomenal results, which means tiny transmitters and vastly extended battery life, so that's essentially a non-issue as well.

There is no such thing as 0 Hz. Think about it, a Hertz is one cycle per second, so zero Hz is the same as 0 cycles in one second, or 0/1. The wavelength (lambda) of such a wave would therefore be v/f (v=lambda*f). Since the speed of propagation of an electromagnetic wave is 300000000m/s (we're assuming that we're transmitting through a vacuum), we get 300000000/(0/1) = 300000000 / 0 = undefined, and so we can see that 0 Hz isn't possible. Instead, we approach 0 asymptotically, such that a wave with a frequency of 1Hz has a wavelength of x, a wave with a frequency of 2 has a wavelength of .5*x, and a wave with a frequency of .5 Hz has a wavelength of 2*x.
Yes, I realize that as you get higher frequencies, you get more and more line of sight only. This isn't a bad thing, however, as this is what makes the whole system work. Sure, low frequencies are great for a point to point link because it can travel great distances easily (think AM radio, I live in Florida and can occasionally pick up stuff from across the country), but in a packet switched environment like IP gives us, you don't need that, in fact, it's undesirable because there would be too much interference from other nodes on the network.
I also realize that to a certain degree (not sure to exactly what degree) higher frequency waves are capable of traveling less distance through air, but as I said, all that is required if you desire greater bandwidth are more receivers, or more powerful ones.

Wireless allows an end-run around the traditional connectivity providers, increasing competition and perhaps supplying a long-term solution if the providers of land-based solutions don't get their acts together. Very very useful. In fact, it isn't news that broadband wireless is ready for deployment, many sites have already been deployed in the past few years.

And at some point, when you're trying to increase frequency, you run smack into a wall - the atmosphere is quite opaque to most of the EM spectrum. Only a few small bands (like radio) are at frequencies where the atmosphere is reasonably transparent. The cost of trying to push anything on a frequency where the atmosphere isn't almost completely transparent would be astronomical. Trust me, the spectrum itself may be infinite, but the usable portion of the spectrum is very finite and going fast.

My other option is ADSL, but even living almost downtown my line barely qualifies, so I won't be going any faster than 384/128kbps, too slow.
I am looking into SDSL from the competing providers, but to get 1.5 mbps (half of the wireless), I am looking at $900 for an unmetered account.
These microwave frequencies are not usable for portable devices, they require line of sight and a directional antanae. While things may change in the future, the spectrum isn't being completely used up. Lets use these frequencies to make things better for home/office use.

In places where there are no phones, no copper wires, certainly no fiber, rf (cellular) is what is being installed.
Bandwidth, like memory prices, disk size and processor speeds gets better every year. Qualcom (the folks who brought you digital cell phones) is offering digital bandwidths greater than 2.0 megs per user.
Ultimately, RF will be the winner. Why wait. Lets start now.

The Australian experience is that yes, Governments will go after big targets.
Wireless broadband is the backdoor out. Not necessarily the "transmit to base" kind advocated for wireless access companies, more the "point-to-point" kind which l0pht (amongst others) have tinkered with.
If people are determined to keep the Internet free, than the key is to have free tubes. Cheap, personal point-to-point networks can form small areas where Free cells can survive and even prosper. As these grow, they can link up, eventually providing uncontrolled tubes for the Internet to route uncensored material into.
Of course, it can be argued that such devices can be regulated. Of course they can, but not in the same easily-policed fashion as a single-point provider. If twenty million people have personal point-to-point, it won't be very practical to regulate them. Examples have been given where the FCC gave up on certain kinds of CB radios.
