FCC Chairman Warns of Wireless Spectrum Gap
locallyunscene writes "'We are fast entering a world where mass-market mobile devices consume thousands of megabytes each month,' FCC Chairman Julius Genachowski warned at CTIA Wireless yesterday. 'So we must ask: what happens when every mobile user has an iPhone, a Palm Pre, a BlackBerry Tour, or whatever the next device is? What happens when we quadruple the number of subscribers with mobile broadband on their laptops or netbooks?'"
Isn't that why our government just auctioned off billions of dollars of our publicly-owned spectrum? So that companies could sell it back to us in the form of a three-year contract?
"Tell me doctor, with all of your defenses, are there any provisions for an attack by killer bees?"
I'm no radio engineer, but it is my understanding that there's been a bit of work on dynamic frequency negotiation that allow devices to find frequencies that are and aren't being used (or what levels of noise there are). I've just started looking into Software defined radio and the more esoteric (and horribly-named IMO) Cognitive radio that theoretically provides the (artificial) intelligence to perform such negotiation. The theory is that this approach makes more efficient use of the same spectrum while improving communication for those devices because their I/O is very flexible. And, the devices are hackable in software, which is fun for the whole family.
If there are any radio people in the room, speak up.
Get rid of the public airwaves and work on letting the market come up with standards -- frequency hopping software radios, hive networks, whatever. It'll be more efficient, cheaper, and it'll provide for much more competition.
er... this is where cellphones are already heading. hell... they are already there.
Today, we still are wasting a significant portion of bandwidth on broadcasting when the future is point to point communications along with some form of P2P crowdcasting.
crowdcasting/p2p is going to evolve significantly. We are already near the cusp i think, given how much traffic is already p2p. Sooner or later p2p is going to be metered and restricted and paid for. As soon as that happens crowdcasting is dead in the water. It only works as long as everyone has 'unlimited bandwidth' right now the market is working out that 'we have a lot, but its not unlimited, but we won't meter it yet because we have enough that most people don't need to know its not unlimited and unlimited is easier to sell... so we'll just deal with the blowback when the very small number people run us into the limits.
Let something like 'crowdcasting video' catch on to the point that it can replace 'broadcast tv', where everyone anywhere watching a TV show is simultaneously p2p serving it back on to the network... at the point the jig is up; and the bandwidth meters will go up.
Don't worry about the physical bandwidth as it will open the door to more ideas like distributed caching and broadcasting single packets among multiple devices. Then again the more people cry about the sky falling the more incentive there is to impliment ideas like this for way too much money to satisfy egos. Wireless is really the way to go for the end consumer and if it does really get that big then cell carriers will devote their towers into the mix(for a price of course). Remember it's not all the bandwidth that's being eaten up it's just this particular portion as demand goes up so eventually will the supply, we will just come up with more effective and clever ways of doing it.
A loop, by its nature, continues. If that didn't make sense, start reading this sentence again.

Is the problem all the silos? Suppose every house with a land-line connection also had a wi-fi hub that was open. I think the bandwidth problem would not exist.
We'd be left with the "how can we profit on this" problem and the "how can the FBI spy on this" problem, but those don't seem nearly as important as the "how can we make information access ubiquitous and fast" problem.
