The 700mhz Spectrum Auction In Perspective 88

YIAAL writes "Writing in Popular Mechanics, Robert X. Cringely looks at the upcoming auction of the 700mbz spectrum, which is currently used for soon-to-be-defunct analog TV. 'Why are all these companies so excited? Because the 60 MHz of spectrum that's about to be auctioned is the last prime real estate for mobile communications that will be available in the U.S. for decades to come ... Some pundits (that would be me) think Google will bid to win its spectrum block, then will trade that block to Sprint/Nextel for some of that company's 2.5-GHz WiMAX licenses that are far better suited for data.' Plus, the prospect of offering unlicensed data service in the 'white space' between existing broadcast channels."

    I'm anxious to see what develops from this. The 700 Mhz band should have a fairly large range (greater than normal wi-fi), but less than a radio station for example, given the same power. I'm interested in what each of the bidders wants to use the band for, most likely for providing wireless internet. At first connection speed might be a problem though, but still acceptable for casual browsing and e-mail. maybe not fast enough for real-time youtube.

      And what would happen if one of the bid winners licensed existing TV stations to broadcast over some specific frequency just as they already are? Sure, it's not innovative or revolutionary, but the broadcast TV model has already proven profitable, and there are a LOT of people in the US with out HD TV's/Converters. Seems like there could be a rather solid market out there to continue the status quo, at least for a while until the HD penetration numbers rise.

        TV broadcasting isn't all that profitable and is severely inefficient. The OTA converter boxes for the small minority who need one (and I am one... rooftop antenna and curbside free 25" TV is good enough for me) will be readily available soon enough. There are hundreds of thousands of them in shipping containers on boats from China at this moment.

          In general I agree, I've played around a bit with my wee small antenna and an atsc tuner, and the results are far better than I was getting with an ntsc tuner. The picture is crisp, clear and consistent in a way that the analog signal never was in this room.

          But anybody that lives out in the boonies, the places where getting quite a bit of static are going to be screwed over if they haven't gone satellite.

          Overall though, I think that the people that are screaming to maintain the status quo and the horribly inefficient allocation of the airwaves for an increasingly small minority need to think about the common good, and consider whether they have a right to forgo paying for a subsidized box if it means depriving everybody of the use of the spectrum.

          It would in many ways make more sense to subsidize a basic satellite package for people that live far enough away from the nearest broadcaster than to maintain the system as it is.

          Even if the spectrum is bought out by a company that misbehaves in the end, we still have an additional choice to make, whereas previously we had one fewer option. And that's a good thing either way, it gives a chance for a new service to sink or swim.

            Actually, you've got that exactly backwards. Those on the fringes who get ANY picture on analog TV stations, should expect to get a perfect ATSC signal. It has been proven in practice a great many times (a web search should turn up plenty of accounts). And more to the point, broadcast radius is, in fact, ATSC's biggest strength over DVB.
            • That is correct except for those of us who live in an area that is prone to hurricanes. The digital tv broadcast is lost long before the analog broadcast i.e. during Katrina, Mobile's NBC 15 broadcasts digital on 47. It was lost 1 hour into the storm, yet 15 never went out. Kudos to the government for the wonderful changes!
              • Does that channel broadcast its analog and digital signals from the same tower? If not, then maybe the digital tower just fell down and the analog one didn't. Or if they are on the same tower then maybe the lines carrying the digital signal to the tower were damaged and the analog ones weren't. There are many possibilities other than just degradation of the signal that could have come into play during a storm as powerful as Hurricane Katrina.
                • Not sure, it just went out. I felt better that once I saw we could still watch analog tv. The fact was it was only 3 1/2 hours into the storm we lost power and the little 5" weather tv only picks up analog tv. Guess, I will have to buy one of those converters to make that work when the power fails off of the old power inverter.

        Based on the auction rules, there is nothing limiting the potential licensees to which technologies they use the licenses for. (Except maybe the blocks designated for public safety.) The cost of each license is probably enough to prevent it. The cost and the geographic limitations that is; most licenses are fairly small (designed for potential Commercial Mobile Radio Services [CMRS]) the exception being Block C in the Upper 700 MHz with is broken into 12 geographic area groupings.

        Traditional analog broadcasts had higher power ratings and larger coverage areas than allowed by the new licenses. The reasons being that the broadcasts were all one direction and the broadcasters were attempting to get the signal to as many people as possible. The new licenses are designed with CMRS in mind. CMRS doesn't use the coverage TV broadcast did, the more coverage the more transmitters requiring a piece of the network. Whereas, TV there was just one transmitter. Because CMRS is all about two way communication, it makes more sense to keep the each transmitting network small and have many of them. That way you can let, say, 20 people transmit within a range of frequencies on 10th avenue and one block over allow a different set of 20 people to transmit within the same range (the network serving 40 people across the two city blocks). Increase the power rating, hence the range, now the same geographic area only serves 20 people because there isn't enough spectrum space to serve more within the frequency range. (Okay, very crude example with very little actual engineering. Somebody familiar with current GSM standards could provide a much more accurate example. But, this should convey the concept.)

        Because the licenses were designed with CMRS in mind, the power ratings are lower and the size of each "cell" is smaller. In order to have effective TV broadcast you would have to buy many of the license to ensure you didn't cause interference over another licensee's geographic coverage.

        Furthermore, it doesn't make sense for a broadcasting company to spend large dollars on new licenses when those broadcasters are all transitioning to digital TV. It makes more sense to just go with the transition and tell consumers that it isn't their fault because the government made them do.

        Basically, there is really nothing in the auction rules themselves, but economically speaking it would not be a wise business decision.

    The article is just plain wrong when it states that the 2.5GHz band is superior for data, it is not. Throughput is primarily dependent on bandwidth, so 20MHz at in the 700MHz spectrum will effectively carry the same amount of data as 20MHz in the 2500MHz spectrum. The big difference is that Google can provide coverage in rural/suburban areas that have relatively low demand for throughput with far fewer sites. In urban areas Google can pack the sites just as closely together and will still be better off then they would with the 2.5GHz spectrum because they won't have to install in-building repeaters to ensure good coverage inside many of the buildings that would otherwise require such a system.
    • I think you're wrong. It also depends on the wavelengths too, which in turn depend on a radio wave frequency. Anyway, shorter the wavelengths more data you can pack in one bandwidth. Since, in GHz frequency range, wavelengths are shorter this means more data you can pack in the same bandwidth.

      As someone who professionally designs cellular networks I can tell you that for data services 20MHz at 2.5GHz is much better than the same 20MHz at 700MHz. The data rate is determined not only by the channel bandwidth but also by the amount of interference that is generated by neighboring base stations. This interference depends on the RF propagation characteristics. At 2.5GHz the RF signals die off much faster with the distance than at 700MHz. As a result your interference levels will be lower at 2.5GHz. The downside is, of course, that cell coverage area of each individual base station will get smaller and you have to deploy them at substantially higher density. Rule of thumb: for voice you are coverage limited and you want your 700MHz (or 850MHz, ATT, Verizon) and big cells. For data you want small cells and high frequency band (2 or 2.5GHz).

      Just my two cents from the tranches.

        You make a lot of assumptions in this argument. Voice today is essentially data - it is digitized information being transferred. Data service quality does not need to be bandwidth limited - SMS is an example of data transfer of fixed bandwidth that could benefit from larger cells. The interference you are talking about is the reason why lower frequencies gives larger cells - with larger cells you have exact the same situation with 700 MHz and 2.45 GHz. Perhaps you are alluding to the measure : bits/second/H

          Well, the practical metric is bits/second/Hz/user.
          Ideally, each cell will serve small number of users at a high data rate. To achieve this goal, the cell coverage area should be smaller than in a typical "voice service" cell that can serve dozens of users at the same time.
