Spectrum Fragmentation Means Pricier Mobile Networking

Posted by timothy on Saturday December 17, 2011 @10:40AM from the why-not-just-include-a-decoder-ring dept.

alphadogg writes "The plethora of spectrum bands used for LTE will result in more expensive devices, and also make the ability to roam globally using the technology less likely, according to industry organization GSM Association's research arm. Wireless Intelligence predicts there will be 38 different spectrum frequency combinations used in LTE deployments by 2015, thanks to ongoing spectrum auctions, license renewals and reallocation initiatives across a wide range of frequency bands. The number of combinations means economies of scale won't be as good and prices won't come down as much as they could if fewer spectrum bands were used as volumes increase, Joss Gillet, a senior analyst for Wireless Intelligence."

  So SDR is going to drive prices down? Not if we're to judge anything from the price of the development kits and software. It sounds like the end-all in theory, but realize that these devices generally work from (a lower) IF frequency down to baseband rather than being completely digital from RF all the way down. You still need an analog front-end in the receiver, and you get a bulkier, more power hungry, more expensive piece of hardware. The need for future-proof, reprogrammable radios is questionable when the hardware is obsolete in a matter of a few years.

  A few years ago, Mirics announced its FlexiTuner, which suits virtually any radio or TV standard. It is a classic front end with RF amps, mixer, PLL synthesizer, and IF filtering. The Mirics MSi001 and MSi002 cover all frequencies from 150 kHz through 1.9 GHz, making them candidates for any radio or TV product. The chips support zero-IF or low-IF formats and provide the I and Q outputs to any demodulator. The control interface is either I2C (MSi001) or serial peripheral interface (MSi002).

  Software works well for the back-end of the radio, ie. detector. The front-end and antenna are another story.
  But antenna's of approximately the right length are almost as good as specifically tuned antennas, and the technology for dealing with multi-wavelength radios is growing by leaps and bounds. See this summary of Fractal Antennas. (full article is paid), as well as this article
  
  Developed over the last 20 years, fractal antennas have proven to be a fundamentally important breakthrough in antenna technology. This technology has allowed for antennas that are more powerful, versatile and compact. Because a fractal antenna uses fractal geometry and builds a complex pattern from the repetition of a simple shape, the inherent qualities of fractals enable the production of high-performance antennas that are typically 50% to 75% smaller than traditional ones. Because antenna performance is attained through the geometry of the conductor, rather than with the accumulation of separate components or separate elements that inevitably increase complexity and potential points of failure, fractal antennas offer better reliability and lower cost than traditional antennas.
  .
  So it would seem, that these antennas are destined to simply be "Printed" onto a substrate, perhaps the back cover of the phone, and segments enabled as needed. One antenna for all bands, just by using different segments to create the best pattern. This is bound to become dirt cheap to make.
  When combined with a software defined radio, rather than the discrete band models we are used to, the flexibility to produce a true world phone is possibly closer than previously thought. As soon as the designers stop chasing multi-discrete-band radios, and just plan for a world of hundreds of band segments, the Software Radio will drive the unit lower than what we have today.

  Every radio transceiver has a transmitter to go with the receiver, and a receiver is more that just a detector. Superheterodyne receivers require several stages of filters and mixers that work for certain bands. Software defined radio might not require as much special hardware for VHF and UHF, but that doesn't mean you can tweak your code and automatically switch over to GHz bands. If virtually everything could be done with software on a power-sipping cpu, what is the likelyhood that the cpu and/or DSP will run at frequencies close to or higher than ( say 2 x ) the frequencies that LTE is supposed to use?

  Please let me re-iterate what the article says: "The plethora of spectrum bands used for LTE (Long-Term Evolution) will result in [***]more expensive devices[***], and also make the ability to roam globally using the technology less likely."
  The issue is not the modulation / coding, which is already performed via software and unconverted (ie software defined radio). The issue is in the RF front-end, which is highly specific to its frequency of operation. This includes FILTERS that are tuned to precise frequencies of operation, POWER AMPLIFIERS that are tuned to a specific frequency (some have slight control over their frequency via IO pins, with trade-offs), and LOW-NOISE AMPLIFIERS to name a few. Anytime you try to make this hardware work over a wider band or become reconfigurable, there are serious trade-offs in efficiency, cost, and overall performance. Cell phone antennas are not the issue.
  Software defined radios generally don't work in the GHz range. They produce signals in the MHz range and up-converted into the GHz range, but thank you Slashdot for trying to teach me how to design a phone! This software-defined fully-reconfigurable world phone is a brilliant idea! I'll let my boss know our next design will be the size of a spectrum analyzer, weigh 10 kg and cost $10,000. And you won't be able to talk and surf because the software defined radio won't have the bandwidth for both the LTE signals and the WiFi signals. Again, THANK YOU SLASHDOT FOR TEACHING ME HOW TO DESIGN A PHONE!
  To add to the cost, forcing cell phone designers to re-design pieces of the phone for different regions will add to the price even more. There's a push to lower the cost by creating one design that can operate in any region (re-designs / modifications are expensive).

  If you must ask why the answer is usually money. Let's assume a company thinks this is a good idea and investigates the possibility. First thing they'd have to do is decide on the specifications on the card. How big would this card have to be? How much power will it consume, and therefore how much heat will it produce? What frequencies will it operate?
  Just looking at the frequency issue the RF connection could be a problem. Materials can act very differently at 800 MHz than it does at 2.3 GHz. A mismatch can mean problems with power consumed, frequency stability, out of band noise, and perhaps other things I missed. One could place the antenna on the card to avoid much of these issues but then it's no longer a card that is inserted in the phone but now the back half of the phone.
  Just thinking of the logistics the phone designer would have to have one part for the UI half of the phone and a part for each frequency of operation for the RF half of the phone. That means tracking N+1 parts instead of N parts when N equals the frequencies of operation. Having talked to engineers that have to track parts they do everything they can to keep part counts down. Just adding another different kind of machine screw to the design can give them fits.
  I suspect that there is already a high level of reuse in the designs on these phones. One chip drives the OS on a number of similar phones, one chip drives the RF on a number of similar phones, one chip drives the display on a number of similar phones. The phone designer can pick and choose from these already existing chips to build a new phone and choosing to design a new chip when there is a desire to add some new feature. To make this common connection standard idea work a phone company would have to convince the chip manufacturers to design a chip to their liking, or the cell phone manufacturers would have to design a board for these chips to sit on to do the translation for them. When dealing with GHz frequencies, and the constraints of a hand held device, this becomes difficult and therefore expensive.
  People's tastes in cell phones shift rapidly, and therefore the designs must come to market quickly. Taking the time to come up with some connection standard, have it tested, and have it future proofed against changes in FCC rules, consumer tastes, and so on, while still allowing for a profit margin sounds quite difficult to me.

  The ROI from owning (licensing) spectrum is a rate: e.g. dollars per year.
  The cost of the spectrum is an amount: e.g. dollars.
  
  The only way to reconcile these two is to either:
  
  Limit the amount of time they can use the spectrum. Then:
  ROI = (dollars / year) * (years) = dollars
  Cost = dollars
  
  or
  
  Make the licensing cost a recurring annual fee, not a one time payment. Then:
  ROI = dollars / year
  Cost = dollars / year
  
  Only when the units for cost and return are consistent can you make an analytical fiscal decision. Even purchases with a one-time fee, like a car, are turned into rates in accounting. You amortize the car's cost over the number of years you expect the car to remain in service. So if the company buys a car with a loan whose total payments work out to $35k, and you expect to use the car for 7 years, then the cost of the car is $35k / 7 years = $5k per year.
  
  Any cap you place won't be arbitrary. It will taken into account in the bidding process. If a company thinks they can make $1 million/yr from the spectrum, and you place an arbitrary cap of 5 years, then they will not bid more than (assuming 10% profit margin) $4.5 million minus interest. If your cap is 10 years, then they will not bid more than $9 million minus interest.
  
  As a fiscal conservative who has run a business and done the accounting for it, our government's insistence on auctioning spectrum in perpetuity for a one-time fee has always baffled me. It's like saying if you pay me $1000 one time, I will clean your bathroom once a week forever.

If the present value of the expected future benefits are greater than the present value of expected costs, as long as your cost of capital is correct the project WILL add value to the firm, regardless of how long it takes. this is called NPV analysis.
  
  The payback period method on the other hand is not based on Economic theory, it doesnt take into account cash flows after the payback period, favors small projects and discriminates against large ones. There's no Economic method to calculate a proper payback period, and so the payback periods are arbitrary.
  
  Many businesses have disregarded great projects that would have added value to the firm but simply had the wrong accept/reject criterion. Accounting methods are not quite appropriate here, since the main point of accounting is to match costs with revenues, and indeed the financial formulas to find a stock's price involve taking the accounting financial statements and working backwards to find the real cash flows again.
  
  About perpetuity, imagine that buying the spectrum was equal to receiving a set number of dollarsfrom the government every year, let's say $1000/year forever. Assume a 6% cost of capital for the company. Now we can easily find out how much this is worth today. 1000/.06 = $16,666.67. (This is a limit simplified down, 1000/(1.06) + 1000/(1.06)^2 + 1000/(1.06)^3 + ...)
  
  That would be the cost you need to pay today to get a perpetual annuity of $1000, kind of like buying rights to the spectrum.
  
  Are you still baffled? It's really just Economics backed with maths.

  This is about the stupidest post I've read in a while. The radio spectrum is almost completely nationalized and has been for the better part of a century. The problem isn't that private owners are speculating with useful spectrum. Nor is it that we don't have a small oligopoly of carriers with absolute control of the spectrum. We already have the FCC, and they pick winners and losers with all of the foresight of an old man who keeps falling down manholes. There is no point in owning part of the spectrum if ownership of it isn't a revenue generator. And it won't be if you're not making efficient use of it, like any other form of property. But when a bureaucracy who cares more about what the FAA and politically-connected wireless microphone manufacturer in Podunk think rather than the entire industry wants to do with spectrum that is partially or fully owned by the government, then the spectrum might as well be nobody's birthright.

  That's hard to do with the frequencies being significantly different. LTE spectrum ranges from 850 mHz to 2500 mHz - a wide spread to handle in a tiny radio. It's possible to do but then you have the annoying engineering tradeoffs of size, battery efficiency and cost.

  Manufacturers would do that if they could, but it's not technically feasible given space, cost, and electrical constraints. That's the whole point of the article. Your antenna needs to be tuned for every frequency band that you support, so there is a finite number that you can support well. Also, the power amplifier must support each frequency band. Also, the RF receiver must support each band and each protocol in hardware. It's not trivial at all to add a new frequency and/or protocol.

  It's not particularly hard to do on a chipset, using DDS technology. What is necessary, are external filters for the specific frequencies/bands, but stuffing different filters/antennas on essentially the same board doesn't really hurt economies of scale, when each band may represent millions of handsets. There's not much economy of scale gained between building 1 million of something, and building 2 million of the same thing, at least when you're talking about $50+ things (i.e. at that scale, you're saving pennies, not dollars).
