The President's Mandate to Commerce Department:

This is from Fast Times Magazine Weblog. Two points to look for: The President's mandate for inexpensive, universal broadband access by 2007, and the concept of unused spectrum being like money lying around. (My editorial comment: When you look at the "geography" of spectrum availability, you can really only start talking about the spectrum above 80 MHz, due to the propogation characteristics that create a world-wide "geography" or footprint below that frequency.)

This mandate really leaves only one option: BPL. There is not time to build out the infrastructure necessary to get a wireless technology deployed universally in 2 1/2 years. The big (BIG) advantage that BPL has is the infrastructure is already in place.

BPL may be the answer -- but it needs to be housed via frequencies that will not allow for propogation (i.e., non-HF).

Disruptive Wireless

Vanu Bose is CEO of Vanu Inc. Michael Gallagher serves as acting assistant secretary of commerce for communications in the U.S. Department of Commerce. Tren Griffin works as a technology evangelist for Microsoft. And Rob Toor is CTO of Ember. What follows is a partial transcript of their panel discussion at Supernova:

Michael Gallagher: When you come from the government, "disruptive" is not a word people like very much. But I'm happy to address the topic and hope to give you some tools you can use to achieve your goals for spectrum working with government rather than opposed to it.

We don't have innovation if we don't have a strong economy. The job creation numbers are very strong. And 70% of the jobs created over the year are above the median income. When it comes to research and development, the president's current budget is 45% higher than it was when he came into office. That's the end of the commercial endorsement.

I work for the National Telecommunications and Information Administration, and we are the government's primary adviser on telecommunications policy. The Department of Commerce is the same department that opens up international markets for your goods. It's also the home of the National Oceanic and Atmospheric Administration, which oversees the environment. Finally, it's home to the technology administration.

The president gave us a goal for broadband -- universal, affordable access by 2007 -- a few months ago. Opening the door to disruptive technologies has been the mindset embedded in our work. Yesterday the president came over to the Department of Commerce and spoke at length on the importance of broadband and spectrum.

Let's look at four examples of technologies we've worked on. The first is 3G. We're very excited about making more licensed frequencies available. The next two, ultra-wideband and 5-GHZ, are unlicensed. The ultra-wideband allotment is very potent. At 5-GHz, we doubled the amount of spectrum made available for shared, unlicensed use. Finally is the millimeter wavelength, a potentially disruptive technology. In a very short amount of time, you'll be able to go to the NTI Web site and negotiate a frequency assignment. That's never been possible before.

In the recommendations to improve spectrum policy for the 21st century -- which were made just yesterday -- we encourage innovation, modernize spectrum management, increase efficiency, and ensure the protection of users.

Broadband over power lines is another exciting development. Clearly it's wired, but it has some interesting wireless impact. In summary, communications are the backbone of our economic and national security. Spectrum is the rocket fuel for innovation. And we intend to continue to move ahead on this path. As you move forward, please remember that we are your bridge and portal to the federal government. The government does not need to be your enemy.

Vanu Bose: Today's wireless devices are hardware based. If you have a CDMA cell phone, it can't be a GSM cell phone. The hardware determines the device. Software radio solves that problem. We want to move so devices become generic transmission and reception devices. The software can determine what the signal becomes. Currently, our business is focused on the military because of the wide range of non-interoperable radios. The challenge getting to a cell phone-like device is limited by battery life -- it does take more energy to do this -- and is probably five years away.

Technology development moves very quickly. Let's look at wireless. That's developed at the rate of one new standard every decade. That's not because it's evolving slowly. It's because they don't make it out to widespread deployment. That's not technical. It's financial. For one recent AT&T build out, they had to add entirely new base stations. With that kind of investment, it can take 7-10 years to make good on that investment. That's why we're trying to make our innovation a software change.

Rob Poor: Ember is an MIT Media Lab spin off that makes the tiny chips and software to drive the Internet to the next level of development. We got our start with DARPA money. We make chips. We make the software that makes those chips self-organizing, self-healing systems. And we help OEM's build them into their products.

If you build connectivity out of silicon, it is guaranteed that it will continue to get cheaper. We're already seeing customers in building automation so lighting can be controlled wirelessly. Phillips wants to partner with property managers so that, smoke detectors, and other devices are all connected. This can lead to mesh technology. How many of you have not experience having to move closer to a window with your cell phone -- or move your laptop over a few inches over at Starbucks to get better connectivity? That's a flaw of the traditional star topology.

Tren Griffin: I'm just back from two weeks in Asia. And we're interested in using wireless for rural connectivity. We're not interested in a phone for every villager, but some kind of wireless connectivity for every village. There's a great little summary in a recent Economist called "A Brief History of Wi-Fi." The most interesting thing about Wi-Fi is that it was all accomplished with so-called garbage spectrum. If you look at spectrum, it's really big. There's good spectrum and there's bad spectrum. The change is going to require some pain and some shifting.

Spectrum is like invisible money. It's just lying on the ground. In these rural countries, if you have some money and you have some spectrum, you can create a network. In rural Montana, there's a lot of spectrum, but there are no devices that can use it. We want two-way connectivity anywhere in the world. We need base stations that cost less than $10,000. We need chips that cost less than $5. We need cheap spectrum that will go through mud, adobe, and brick walls.

That spectrum needs to be used here. Why? Equipment companies don't build equipment to be sold in developing countries. They develop them for use here and then sell them over there. There's going to be a battle for the spectrum. It's like beachfront property. Let's get that spectrum out into the hands of the people who need it. 30% of kids in India do not go to school. 70% of people in China live in the countryside. Some people have a vested interest in squatting on spectrum. If you have interest in what happens in the developing world, you need to step up and get involved politically. This needs to be grassroots.

The President's Mandate to Commerce Department:

I don't mind if the technology is disruptive, but I sure don't want it to be *destructive*. The mindset, it seems to me, is that the US government thinks that BPL can raise the HF noise floor at no cost to performance of the incumbent MF/HF/lowVHF users. What is the technical reason for limiting BPL to 1.7-80 MHz? I suspect there is none. However, if BPL were to be implemented in the 0.5-1.7 MHz band, the AM broadcasters would raise a stink (it will decrease their coverage areas), and the AM listeners would hear BPL for what it really is: NOISE (harmful interference).

Interesting position statements, but interpretation is needed to understand exactly where these people and organizations are going. Only Michael Gallegar mentions "disruptive technologies" and BPL, and suggests that, though the government doesn't "need to be your enemy", they are moving ahead regardless. The others just state their positions, relating only to wireless technologies, and it wasn't clear to me that they've ever even met each other.

N5NW is to be thanked for posting this, as it gives us a little insight into where the current administration's FCC and a few commercial players are headed, but he misses the fact that BPL infrastructure is NOT in place, except for poles and wires. Certainly this reduces the cost of installation greatly, but there would still be a need for many, many pieces of hardware to move data on and off the power lines, to move data around transformers, etc. posing a huge cost for implementation, which would not be done within the administration's 2007 target time anyway. It is also certain that, at some distance out into the BPL network, the cost of hardware to reach the often-cited "last mile" customer will exceed any revenue that might be gained from that customer, invalidating the whole "last mile" concept. Well, maybe "last mile" is just hype anyway, from the administration's efforts to sell this new and profitable annuity they're promoting for their energy company campaign contributors and buddies.

It looks pretty certain that wireless standards 802.16 and 802.20 (longer range counterparts to WiFi 802.11 systems) could be implemented in the high-profit populated areas within the same timeframe, providing much more profit and service per customer and a lot less trouble to existing communication systems including those on HF. The "last mile" customer will still be stuck with high cost satellite service or high one-time installation costs (read: burying or stringing fibers or putting up dish-and-receiver systems), but that is probably unavoidable. The wireless standards do have the promise of reaching a lot more customers economically in the "next-to-last-mile" category, however.

I truly hope BPL will die a quick death, or just fade out of use, as other and better standards are implemented. I, for one, am working to raise the consciousness of our lawmakers, along with others, about the problems of BPL (which affect many more groups besides amateur radio ops) and the cost effectiveness of WiMax 802.16 and 802.20. In the meantime I hope more people will understand the importance of voting out of office the LEAST publicly responsible federal administration in my lifetime.

Good reception to all. 73 de kt8k - Tim

I think one of the reasons is that it's just easier to get 1.7-80 Mhz to propagate along the power wire. The reason they don't cover .5-1.7 or 88-108 Mhz is obviously clear. I think their best bet is to use the soon to be vacant broadcast TV spectrum. But no matter what spectrum they use, it will still be polluting.

It will always be "polluting" if that means radiating RF, but if it operates in designated spectrum far above HF it has the potential to minimize negative impact and provide cheaper and more efficient internet access to the masses, without interfering with existing services. WiMAX has the potential to do this. Read www.ieee802.org/16 and I think you will see what I mean.

There's already a lot of infrastructure for wireless WiMAX in place - look at all those cellphone towers!

Mr. Griffin says:
"Some people have a vested interest in squatting on spectrum. If you have interest in what happens in the developing world, you need to step up and get involved politically. This needs to be grassroots."

Looks like all the spectrum users are going to have to become "involved politically".

Are you registered to vote? Do you know where your preferred local political party has its office? Some work needs to be done.

"disruptive technology" say it all. Look at the synonyms for and the definition of disruption. Interference is right there at the top.

Therefore, if they are talking about "disruptive technology," they are talking about interfering technology.

I think that is enough said.

I don't understand the infrastructure issue at all. The amount of hardware that will be needed to implement BPL and and WiFi, WiMAX, and any other broadband technology should be about the same. It may be true that the wire infrastructure is place for BPL, but the condition of that wiring isn't the best and they still have to install circuitry to bypass transformers and install some sort of distribution system to get the network from the ISP servers to the BPL distribution. This will take cable, fiber, or wireless. In the case of wireless, why not just go with it for the entire installation.

"This mandate really leaves only one option: BPL. There is not time to build out the infrastructure necessary to get a wireless technology deployed universally in 2 1/2 years. The big (BIG) advantage that BPL has is the infrastructure is already in place.
"

What infrastructure, the wiring? Wireless and BPL will require the same amount of infrastructure. There will still have to be repeaters and etc. for wireless. This is no differenct from BPL. The utilities still have to get a vendor to provide the necessary hardware to circumvent the transformers and account for the resistive and radiative loss in the system. I fail to see why having a lot of wire in place makes BPL any less expensive than wireless. In fact, it seems the only advantage is the use of Part 15 with little restriction placed on them so they can grow this service with minimum interference with their business plans. Wireless, even if it is Part 15, will required spectrum analysis and the selection of appropriate sharing partners.

Competing spectrum use technologies should be placed along side of other technologies with similar characteristics. HF is dominated by narrow band technologies that utilize the unique properties of ionosphere propagation to provide critical and entertainment services. Broadband and narrowband technologies can coexist, but not in an environment where weak sign work is on going. Better sharing partners would involve the use of FM users where an increase in the noise floor would be hardly noticed or spectrum where other spread spectrum techniques are employed.

In conclusion, I think the fact that infrastructure such as wiring is in place is not a satisfactory argument for justifying BPL, though the argument does sound good to the non-technical public. Wireless at UHF and Microwave frequencies makes more sense. The only real argument for BPL is the potential income to the utilities or the enhanced grid management that they envision, I must say that this is of primary interest to the utilities. They will get a new and enhance system for grid monitoring and control at our expense.

BPL is strip mining for the air waves. If all you see
is the money laying there in the ground and you
don't care what the landscape looks like afterwards,
why wouldn't you want to strip mine the place?

Similar policies let to the demise of telecommunications companies. Several companies went out of business, because the amount of capital investment was much larger than the incoming cash flow.

Regardless what your position on BPL is (in my case it's a spectrum polluter, which will violate PART 15 rules), it sounds as if no one in those companies is performing a ROI calculation, and/or a demand calculation to see if they would get any money out of it.

What's so polluting about WiMAX-type services? For the most part they have little potential to interfere with ham services. I used to have (until the company went out of business, sadly) 1xEVDO wireless broadband for $40 / month. The service was generally pretty good, considering how new the technology was at the time, although it did cause some interference on the HF bands IIRC, I believe that it was short-range for the most part. I really think for rural areas wireless is the answer.
