Wireless Broadband's Big Appetites

It is good news that the bad news is not all that bad. There will not be a spectrum crunch. But there is one now. The possibilities have not been realized.

The Spectrum Crunch that Never Really Was
Cisco estimates that mobile data traffic will grow by a factor of 18 by 2016, and Bell Labs predicts it will increase by a factor of 25..... when wireless networks are overloaded, the real culprit may be inefficient use of existing spectrum rather than a fundamental shortage. ..... "We don’t have a spectrum crunch so much as we have a spectrum policy crunch .... The so-called ‘spectrum crunch’ really reflects artificial spectrum scarcity" ..... “The challenge now is to extend those proven successes to enable wider-area broadband access using other underutilized portions of the spectrum.” ... such strategies could increase wireless capacity by thousands of times...... half the new demand through 2015 would be handled by small cells—Wi-Fi plus cells handling frequencies used by 3G and 4G networks ...... it might be possible to increase capacity tenfold even without spectrum sharing. ..... rigid regulations don’t allow the use of flexible new technologies like cognitive radio ...... “Right now, we have a 15- to 20-year backlog of new technologies and architectures, including sharing and small cells, which can take us a long way into the future.”

150 Mbps Wireless Broadband

Telstra mobile phone Base station - Wireless H...Image via Wikipedia150 megabits per second download speed: that's pretty amazing.
iTWire: 149.4Mbps over wireless broadband: Telstra and Huawei are testing LTE mobile broadband using 1800MHz spectrum ..... this was more than three times the peak speeds achieved with current mobile technology. .... "As mobile customers move away from 2G services and onto 3G and LTE, 1800MHz spectrum will increasingly become available to be re-farmed by operators. The overwhelming success of these trials shows that 1800MHz can be an attractive option for deploying LTE where access to other spectrum bands is constrained" ..... Earlier this year, Huawei set a record LTE-Advanced download speed of 1.2Gbps at the CTIA Wireless 2010 event held in Las Vegas.
1 gigabits per second is even more impressive.

Broader Broadband


Fred Wilson: The National Broadband Plan

My comment to Fred's post that I left at his blog: Of all the blog posts I ever read at this blog, and I have read my share, this post really stands out for me. This topic gets me like nothing else in computing.

"....another 500mhz of hiqh quality spectrum to be used for "terrestrial broadband services" over the next decade...."

This is miserly. This is not going to cut it. TV needs to take second place to broadband. This is not some tertiary concern. This is the number one - Numero Uno - thing America needs to do to become a post-industrial, information age economy. The government just needs to get out of the way. The government selling that spectrum space to a handful of old companies is the government getting in the way. The American people need to revolt like they revolted against the British.

The nastiest part of that phrase is "over a decade. This has to happen in 2010, not in 2020. The jobs are needed now, "look around."

xMax


WiFi was wireless but not broadband, and not large area. Broadband over power lines was broadband but not wireless. WiMax was both: wireless and broadband. And today I read about xMax. It is wireless broadband without the WiMax hassles, it seems like. It looks like power to the people to the power of x. This is delightful. This is real good news. The basic thrust is towards wireless broadband. For a city in a wireless broadband soup, cellphones should become free. Cellphones that are ad-based. This is a brave, new world.

Into the Nitty Gritty Of WiMax

The whole point of the internet has been to open things up but, paradoxically, the way people have so far accessed that same internet has been a closed system. WiMax promises to bring openness to the access point itself.

The whole idea of old companies getting washed away, and new companies coming to occupy center stage, old industries disappearing and new ones emerging, old markets evaporating off and new markets getting created, old jobs getting lost and new ones created, that whole churn is an essential vitality of the market mechanism. Change is inevitable, change is desirable. As to what change, and how much, it is ultimately for the customer to decide in a marketplace that is not otherwise distorted. Daring entrepreneurs and dedicated public servants in political offices have the option to forge new partnerships to make sure the consumer is made supreme and stays supreme. There is that futuristic, visionary crown that every cutting edge company wears, and in that zone it is more about ideas and less about the heat of the immediate market, but ultimately that heat has to be faced.

WiMax, in essence, is a challenge to the market mechanism and democracy itself. Will the public servants be there for the public? That question is going to loom large in a very basic way. Because WiMax turns internet access into "roads." At that point it is no longer Cable TV, but more like public television. There will still be alternative ways to access the internet, and niche markets where the private sector runs the show and makes money, but the mainstream way of people coming online is surefootedly headed into the public domain.



Once that achievement is made, it will be a fundamental departure, not only in a major collective boost in productivity, but in many other ways. Society speeds up. Social progress speeds up. It truly is one global village at that point.

Intel has said WiMax is the biggest thing to happen to the internet since the internet itself. I buy into that assertion.

Ubiquitous broadband redefines home, work and school, three of the fundamental social institutions. The ramifications are many. Lifelong education, for one, like an uncut umbilical chord, at that point can be taken for granted.

If the impact on the American scene is to be astounding, that at the global scale is to be mind-blowing. The vision of connecting every human mind to the web stands to be realized. That internet access will be like having invented money for the first time and introduced into the social domain: then it takes a life of its own, and becomes a permanent fixture of the mental landscape, like a mountain, or an island, or a cockroach. We no longer think of it as our creation, but very much a gem of the natural landscape.

At that point, internet acces is like plumbing. The interest is in the water: the plumbing should stay out of sight.

The WiMax Appeal

The WiMax appeal is that it is broadband, and it is wireless, and it can be "spread" over a large area like that of a city, and hence is the only take-you-online-fast technology that can be the internet parallel of what we have in the form of roads for our cars. At the WiMax level, broadband internet can be passed on to the municipality.

It is a young technology, sure. There are all sorts of naysayers. There will be fits and starts, but ultimately it will prevail. Because the vision is so clear: wireless broadband over a large area. The component bits and pieces will be ongoing work. Refinements will be made. But there is no doubting the basic thrust of it all.



Curiously the biggest challenge is not that the technology might not emerge or might not live up to the "hype," but that entreched, rival, old technologies and their corporate patrons might play dirty. The tussle is political. If the market mechanism is driven by consumers, as it should, WiMax will prevail nevertheless.
