Designed To Let Us Down... our deliberately frail cell phone system

cell-phone-p2pDr. Andrew J. Viterbi, an expert on communications theory at USC, spoke up recently in support of one of the concepts I have been pushing. Based upon the obscene situation that we saw during the Hurricane Katrina Crisis, when tens of thousands of victims found themselves cut off from the world, even though they had, in their pockets, sophisticated radio communications devices -- cell phones that betrayed folks the very moment they were needed most. Viterbi commented (and apologies for the embedded self-quotation):

Brin goes on to say that the teachable moment provided by Katrina was lost, and that the cellular industry could make a relatively simple, inexpensive change that would allow cell phones to still function to network survivors in a crisis :


emergency-cell-phone-network".... almost no attention has been paid to improving the reliability and utility of our cell networks, to assist citizen action during times of emergency. To the best of my knowledge. no high level demand has gone out - from FEMA or any other agency -- for industry to address cell-system problems revealed in the devastation of America 's Gulf Coast. A correction that should be both simple/cheap and useful to implement.

"What do we need? We need ways for citizens to self-organize, both in normal life and (especially) during crises, when normal channels may collapse, or else get taken over by the authorities for their own use. All this might require is a slight change -- or set of additions -- in the programming of the sophisticated little radio communications devices that we all carry in our pockets, nowadays.

"How about a simple back-up mode for text messaging? One that could use packet-switching to bypass the cell towers when they are down, and pass messages from phone to phone -- or peer-to-peer -- at least among phones that are of the same type? (GSM, TDMA, CDMA etc.) All of the needed packet-switching algorithms already exist. Moreover, this would allow a drowning city (or other catastrophe zone) to fill with tens of thousands of little spots of light, supplying information to helpers and reassurance to loved ones, anywhere in the world."


cell-phone-failureThese pushes of mine have not gone completely ignored or unnoticed. As Viterbi's riffs on the topic show, there have been some fascinating and insightful exchanges, discussing how the nation and public might benefit by adding peer-to-peer supplemental capabilities to the present cell system.

Some object that this development could cost millions. But that is not any real obstacle in an industry making hundreds of billions in the US alone. If either the government or the cell companies saw a clear benefit model, it would be trivial to justify the relatively small expense. Certainly far smaller than incorporating web browsers and MP3 players!

The problem is that top-down hierachy mentalities do not easily grasp the potential of flattened networks.... and this despite the clear example of the Internet itself, as a super-empowering, hierarchy-flattening phenomenon.

(Indeed, I believe that there are underlying PSYCHOLOGICAL REASONS that the twin examples of the Internet - and citizen competence on 9/11 - may have prompted an immune reaction against citizen empowerment, on the part of some members of the Paid Protector Castes. But that's another story.)

One more-cogent objection to the notion of augmenting cell phones with Peer-to-Peer capability: it takes a lot more energy to transmit than to receive. Most cell phones are actually very weak transmitters that function poorly without energetic base towers nearby.

P2PThe answer to this objection is simple. In order to use P2P effectively in a crisis, when the towers are down, personal cell phones do not have to carry voice. In an emergency, text messages can make a tremendous difference, e.g. in calling for help, or informing loved-ones that you are okay, or in passing crucial information to authorities. Especially since text messages can be transmitted with multiple repetition-redundancy, simple calculations show that pocket transmitters (cell phones) could pass these along at trivial power expenditure.

Obviously, this same answer deals with objections that P2P (peer to peer) does not carry voice well. So?The algorithms for passing along text messages are very little different from classic packet switching for email, on the Internet. Implementation ought to be trivial.

How to explain why this simple augmentation has not been implemented, even though it is clearly in the national and public interest? One theory is that the cell companies may feel threatened by P2P capabilities. Or that they see no way to make money off them. But this needn't be a problem. For one thing, it should be easy for each hand set to track passed-on messages and inform the network, for billing purposes. Or else the P2P system can be turned off, whenever there is a fully functional cell tower nearby! Thus, automatically reverting to P2P only under circumstances when the capability is actually needed!

201817627023139616_3LLO5hNJ_cMoreover, there is an added allure to this approach, one that could help the cell-cos make real money. By developing P2P capability, companies may open the door to a new method for solving their "last mile problem" - or how to extend coverage into dark zones, just beyond reach of their current network of towers. Think. Why not let customers who happen to be at the edge of the coverage area get a small pay-back fee for every text message that they pass through, from people who are just outside the covered zone? The same way people with solar or wind generators can make their meters run backward, feeding power into the grid.

If such customers had a more sophisticated home-cradle unit, they might even be able to pass through voice calls from a nearby dark zone. Reducing their own bill, helping the company, and making our entire communications system more robust.

Indeed, can anyone doubt that someday, somebody will realize there is a business plan in this? An entirely peer-to-peer network, in which, customers home-cradle units make up the bulk of an alternative cell system? But we'll save that futuristic sci fi scenario for another time. What I am talking about, here, is something that could be implemented in just one year, if anyone (like FEMA) were actually serious about fostering a more resilient and robust society. A pretty big "if" - apparently.

9-11The fact that cell phones served the national defense so well on 9/11, yet failed in Katrina, should have been enough to tell us that serious work is needed, work that has been entirely lacking while we let ourselves be distracted on other adventures. I mean, isn't it a no-brainer for Homeland Security and FEMA to support this kind of capability, in the national interest?

After thinking about it, how do YOU feel about the sophisticated little tranceiver radio in your pocket, now that you know that it was designed almost perfectly to let you down, someday, at the very moment that you might need it most?

How societies work... and improve...

I have just cross-linked my “Adopt An Ostrich” article on Daily Kos. (It took a little while to figure out the convoluted format.) I’ll only do this for the most “important” essays and I doubt I will do much comment-response there. So any Kos-ers who keep an eye open over there, please let me know if I ever need to pay closer attention.

ostrichpapersAnd yes, go thou forth, all of you, and Adopt an Ostrich! Seriously. People like you are only a couple of degrees of separation from the civil servants and skilled officers who we must reach. The inherently conservative -- but modernist and deeply loyal and sincere -- men and women who are members of the Protector Caste, who need to be awakened to a basic truth. That the Republic and civilization is in greater danger now than it has been for all our lives, and from an enemy as bad as communism ever was.

If we can waken enough of these sincere Goldwater conservatives, a tipping point may be reached and our civilization may yet be saved. Be tenacious, relentless.


==How Societies Work==

SOCIETIESSome of you may be interested in a paper by Rand Corp research David Ronfeldt, part of his continuing efforts to develop a framework about social evolution -- past, present, and future: In Search of How Societies Work: Tribes -- The First and Forever Form.

I’ll give the entire abstract here, because I think it is a fascinating topic and one worth considerably more sophisticated thinking than most of us apply to it.

ABSTRACT: "The latest in a string of efforts to develop a theoretical framework about social evolution, based on how people develop their societies by using four forms of organization-tribes, hierarchical institutions, markets, and networks-this installment focuses on the tribal form. The tribal form was the first to emerge and mature, beginning thousands of years ago. Its main dynamic is kinship, which gives people a distinct sense of identity and belonging-the basic elements of culture, as manifested still today in matters ranging from nationalism to fan clubs.

"This report provides a lead-off chapter that sketches the entire framework, plus a "rethinking" chapter that shows why David Ronfeldt thinks that social evolution revolves around four forms of organization. A chapter then traces the evolution of tribes and clans, and the final chapter describes modern manifestations of the tribal form. An appendix reprints three op-ed pieces that sprang from Ronfeldt's efforts to understand the tribal form and its continuing relevance. Ronfeldt maintains that societies advance by learning to use and combine all four forms, in a preferred progression. What ultimately matters is how the forms are added and how well they function together. They are not substitutes for each other; they are complements. Historically, a society's advance-its progress-depends on its ability to use all four forms and combine them into a coherent, well-balanced, well-functioning whole. Essentially monoform tribal/clan societies and biform chiefdoms and clan-states, some dressed in the trappings of nation-states and capitalist economies, remain a ruling reality in vast areas of the world. It therefore behooves analysts and strategists who mostly think about states and markets to gain a better grip on roles the tribal form plays in both national development and national security.”


Fascinating stuff, by one of the brightest and most agile social thinkers around.

And while we are being intellectual, let me reiterate the recommendation that folks have a look at Must-know terms for the 21st Century intellectual by George Dvorsky. Another fellow who pours far too much energy into blogging... to our benefit. Dvorsky strives to come up “with a list of the most fundamental and crucial terms that are coming to define and will soon re-define the human condition.” Following all the links could keep you plenty busy. Too busy to go out to bars hunting for a mate. So it is a eugenics plot, after all.

==Mass-produced laptops==

See screen shots of the proposed GUI for MIT $100 computer... the project, the initiative to put $100 laptops in the hands of children around the world. The interface uses a highly abstracted spatial navigation metaphor, an extension of the familiar desktop metaphor, for easy, intuitive navigation that makes the most of the laptop’s networking capabilities. Children can move through four levels of view—Home, Friends, Neighborhood, and Activity—and connect with others in the network “mesh” formed by users.

Of course this is an area of great interest. Let me offer some thoughts.

1) by the time these laptops are mass produced, they will also have cheap cameras, augmenting the effect that cell phones are already having in the Developing World (see my earlier posting about this) empowering local activists with powerful tools of reciprocal accountability. (Obviously I am expecting that parents will also use these machines.) The proliferation of cameras, P2P computer nets etc will worry hierarchical despotisms... And yet the most sincere of those despotisms will WANT some of the anti-corruption effects of reciprocal accountability to apply upon LOW level public officials, whose waste and parasitism depletes the entire nation, the way an infestation of tapeworms can impoverish your body. You can expect nations like China to embrace grass-roots anti-corruption efforts, enhanced by these tools, while suppressing them at national levels.

2) As mentioned, there is discussion of empowering these laptops with peer-to-peer (P2P) capabilities so that they can network even without the existence of local hubs. If this happens, it will be one more example of how the 3rd world may leapfrog past the 1st world, with capabilities that we, here in the West, badly need. I feel that today’s cell phone companies, for example, have utterly betrayed the national and public interest by not engendering a P2P backup capability for at least text messaging -- capabilities that would have proved useful during crises like Katrina. (See more about this under “Comments” later, just below.)

If another disaster happens, in which many thousands or millions are cut off, with charged/sophisticated radios in their pockets that are completely useless when needed most, there will be hell to pay. Or there ought to be. Next time, the cell-cos themselves may get some of the blame.

3) Back to the $100 laptop. It is a great program and deserves massive support. And yet...

And yet... you keep hearing about how smart the interface design people at MIT are... and I don’t get it. The layered GUI of the proposed $100 laptop is sweet and intuitive... and still misses several key insights having to do with allocation of scarce human attention. It is an incremental improvement... and may do a lot of good. But it patronizes the ultimate users. And strenuously avoids the bigger steps that would actually help make things a lot better.

==Communication for the 21st Century==

EpoceneInteractionAnd yes, this segues into my Holocene invention. The recent awarding of my incredibly broad (126 claims) patent has somewhat raised the level at which people are taking these ideas seriously. Seriously... but often with a sense of heated rage... almost like the way a tsunami of geek-letters poured in, after my “Why Johnny Can’t Code” article, a few months back.

So far, I have been amazed by a rich variety of responses that seek to AVOID discussing the issues raised by my patent... how to help online users divide and allocate scarce attention across screen based environments, using methods and tools similar to those we already have used in the real world, ever since the caves.

Instead, a majority seem driven to complain at peripheral issues like:

“Why would anyone want to do that?”
“How can you patent something so obvious? Of course there’s prior art!”
”Patents are evil!”


Look... either these things are being done, usefully, right now, or they are not. The question is a simple one. And yet, a vast majority seems determined to avert their gaze in ANY direction but at the very basic issue, almost as if it hurts to look at a conceptual blind spot...

...but I won’t waste space here at the top level, answering this nonsense, especially since a few of the very brightest out there are starting to lift their heads from the depressing-dulling imagination-suppressing effects of the 21st-Century-So-Far.

I may add a little riff, below, in comments, elaborating. Overall, though. I am learning the value of patience. Waiting for the times to catch up, I suppose.

Worldchanging News: Tools for Enhancing 21st Century Citizenship

Now here is a riff on what new technologies could make the most difference?

"What needs to be done in the near future? What worldchanging tool, model or idea will you be watching (or hoping to see emerge)? What key piece of knowledge do we need? What action must we take? What do we do now?"

Tools For Enhancing 21st Century Citizenship

by David Brin (12/06)

Across the 20th Century, a growing array of problems were solved through the application of professional skill. We came to rely increasingly upon professions ranging from medical doctors to law enforcement to teachers to farmers for countless tasks that an average family used to do largely for itself. No other trend so perfectly represents the last century as this one, spanning all boundaries of politics, ideology or geography.

And yet - just as clearly - this trend cannot continue much longer. If only for demographic reasons, the as the rate of professionalization and specialization must start to fall off, exactly as we are about to face a bewildering array of new -- and rapid-onrushing -- problems.

How will we cope?

Elsewhere I speak of the 21st Century as a looming "Age of Amateurs," wherein a highly educated citizenry will be able to adeptly bring to bear countless capabilities and individual pools of knowledge, some of which may not be up to professional standards, but that can find synergy together, perhaps augmenting society's skill set, at a time of need. We saw this very thing happen at the century's dawn, on 9/11. Every important, helpful and successful action that occurred on an awful day was taken by self-mobilized citizens and amateurs. At a moment when professionalism failed at every level. (Hear a podcast on this topic.)

It is important to note what a strong role technology played in fostering citizen action on 9/11. People equipped with video cameras documented the day and provided our best post-mortem footage. People with cell phones organized the evacuation of the twin towers. Similar phones stirred and empowered the heroes who fought back and made the Legend of Flight UA 93.

In sharp contrast, the events of Hurricane Katrina showed the dark side of this transition -- a professional protector caste (crossing party and jurisdiction lines: including republicans and democrats, state, local and federal officials) whose sole ambition appeared to be to staunch any citizen-organized activity, whatsoever. Moreover, the very same technology that empowered New Yorkers and Bostonians betrayed citizens in New Orleans. Thousands who had fully-charged and operational radios in their pockets were unable to use them for communication -- either with each other or the outside world -- thanks to collapse of the cellular phone networks.

This was a travesty. But the aftermath was worse! Because, amid all the finger-pointing and blame-casting that followed Katrina, almost no attention has been paid to improving the reliability and utility of our cell networks, to assist citizen action during times of emergency. To the best of my knowledge. no high level demand has gone out - from FEMA or any other agency - for industry to address problems revealed in the devastation of America's Gulf Coast. A correction that should be both simple/cheap and useful to implement.

What do we need? We must have new ways for citizens to self-organize, both in normal life and (especially) during crises, when normal channels may collapse, or else get taken over by the authorities for their own use. All this might require is a slight change -- or set of additions -- in the programming of the sophisticated little radio communications devices that we all carry in our pockets, nowadays.

How about a simple back-up mode for text messaging? One that could use packet-switching to bypass the cell towers when they are down, and pass messages from phone to phone -- or peer-to-peer -- at least among phones that are of the same type? (GSM, TDMA, CDMA etc.) All of the needed packet-switching algorithms already exist. Moreover, this would allow a drowning city (or other catastrophe zone) to fill with tens of thousands of little spots of light, supplying information to helpers and reassurance to loved ones, anywhere in the world.

Are the cell companies afraid their towers will be bypassed when there's no emergency? What foolishness. This mode could be suppressed when a good tower is in range and become useful automatically when one is not... a notion that also happens to help solve the infamous "last mile connectivity problem." Anyway, there are dozens of ways that p2p calls could be billed. Can we at least talk about it?

The same dismal intransigence foils progress on the internet, where millions of adults use "asynchronous" communications methods, like web sites, blogs and email, but shun "synchronous" zones like chat and avatar worlds, where the interface (filled with sexy cartoon figures) seem designed to ruin any chance of useful discourse. For example, by limiting self-expression to about a sentence at a time and ignoring several dozen ways that human beings actually organize and allocate scarce attention in real life.

When somebody actually pays attention to this "real digital divide" - between the lobotomized/childish synchronous chat/avatar/myspace world and the slow-but-cogent asynchronous web/blog/download world -- we may progress toward useful online communities like rapid "smart mobs." Only first, we are going to have to learn to look at how human beings allocate attention in real life! (For more on this: http://www.holocenechat.com)

Oh, there are dozens of other technologies that will add together, like pieces in a puzzle, synergizing to help empower the magnificent citizen of tomorrow. Facial recognition systems and automatic lookups will turn every pedestrian on any street into someone who you vaguely know... a prospect that cynical pundits will decry, but that was EXACTLY how our ancestors lived, nearly all of them, throughout human history. The thing to be afraid of is asymmetries of power, not universal knowledge. The thing to protect is not your secrecy, but your ability to deter others from doing you harm.

Likewise, I assure you that we are on the verge of getting both LIE DETECTORS and reliable PERSONALITY PROFILING. And yes, if these new machines frighten you, they should! Because they may wind up being clutched and monopolized by elites, and then used against us. I am glad you're frightened. If that happens, we will surely see an era that makes Big Brother look tame.

And yet, the solution to this danger is not to "ban" such technologies! That is exactly what elites want us to do (so they can monopolize the methods in secret out of our skeptical eye). No, that reflex sees only half the story. Come on, open your mind a little farther.

What if those very same -- inevitable -- technologies wind up being used by all of sovereign citizens of an open democracy, say, fiercely applied to politicians and others who now smile and croon and insist that they deserve our trust? In other words, what if we could separate the men and women who have told little lies and admit it (and we forgive them) from those who tell the really dangerous and destructive whoppers? Those who are corrupt and/or blackmailed and/or lying through their teeth?

In that case, won't we have a better chance of making sure that Big Brother doesn't happen... ever?

Oh, it is a brave new world... We will have to be agile. Some things will be lost and others diminished. (We will have to re-define "privacy" much closer to home, or even just within it.)

On the other hand, if we don't panic, we may see the beginnings of the era of the sovereign and empowered citizen. An Age of Amateurs in which no talent is suppressed or wasted, and no problem escapes the attention of a myriad talented eyes.

As many of you know, I have touted the beautiful and fascinating Worldchanging Book as a perfect holiday gift, expressing much of the resonant message of modernist problem solving that we once saw in the old Whole Earth Catalog.

World changing is also one of the prime modernist web sites! Indeed, I'd like to pass on a message from editor Alex Steffen, asking for a little help (in the spirit of "proxy power.") The previous riff I wrote at his request.

" Okay, here's the deal: I need to hit you up for some money. Not much, only $10, but still, your donation is critical for us, and here's why: Yahoo! is offering a $50,000 matching grant for the nonprofit which gets the largest number of donations before the end of the year using its new "charity badges." What matters is not the number of dollars, but the number of donors. Right now, you need 70 to be in the lead, but things are moving fast and we'd like 500 to be safe. We currently have three (though we just started a couple hours ago). If we're winning on Dec 31st, we think one of our major donors may step in and help us with a large donation, so we'll get the full $50K from Yahoo! $100,000 would be a major portion of our annual budget and you can help us win it."

Got it? Do it! Good.
