Spectrum Public Notice

September 25th, 2009 by Phil Bellaria - Director, Scenario Planning, Omnibus Broadband Initiative

Phil Bellaria BBQuick follow-up to my previous post:

This week, we also released a Public Notice asking for comments on spectrum for wireless broadband.  Essentially, we'd love data, analysis, and focused comments in the following areas for mobile wireless broadband, fixed wireless broadband, and wireless backhaul:

  • How does the capacity of existing spectrum allocations compare to current and future expected demand for wireless broadband & backhaul services?
  • How should we calculate the relative value of different uses of spectrum?  (e.g., wireless broadband, broadcast TV, mobile and fixed satellite services, military, federal government, other industrial uses)?  How should we calculate the relative value of unlicensed vs. licensed spectrum?
  • Which other spectrum bands might be appropriate to repurpose for wireless broadband?
  • What mechanisms could facilitate the transition from incumbents to new users in these bands?
  • What other spectrum management practices should we consider to ensure spectrum is being used most productively?

The basic "who, what, where, when, why, how" questions about spectrum.  For more details, background and context, see the Public Notice.  You can respond directly to this blog or file comments through ECFS Express (or our standard submission page if you need to attach a file). Please title comments and reply comments responsive to this Notice as "Comments (or Reply Comments)-NBP Public Notice # 6."

    On the use of TV white spaces, I think the FCC needs to eliminate the auto-detection techniques from that scheme entirely. Auto-white-space-detection schemes, followed by transmissions at even levels as low as 100 milliwatts, would almost guarantee interference with somewhat distant TV signals. This is not the same as cellular telephone or WiFi hotspot environments, where the strongest signals are usually the desired ones. In this instance, much of the time, the legitimate users of the spectrum will be at very low field strengths.

    I suggest that use of TV white spaces could be allowed, but based one specific frequency assignments market by market. And ad-hoc networks created by consumer devices, in these TV white spaces, should be strictly forbidden.

    Mr Bellaria:

    This is in response to your last blog question regarding "what other spectrum management practices should we consider to ensure spectrum is being used most productively?" It would appear that the Commission, through this blog and other channels, is at last making an effort to fully explore, learn, listen, digest, and, hopefully, understand the best methods of approaching the vast challenges it faces in bringing broadband Internet - particularly wireless broadband - to the masses. Wired Internet is, of course, one method; wireless Internet is yet another, but - please remember that it comes with an entirely different (and often overlooked or mis-applied) set of technical and network characteristics that are required to insure usable, reliable and non-interfering content delivery via any form of RF (radio frequency). Thus, I would strongly encourage the Commission to 1) pay very close attention to the many technical details that are associated with the provision of broadband Internet via radio frequency, and 2) just as close attention to the marketing spins and political rhetoric that it will be inundated with as it moves forward with its national broadband initiative. Not doing so would be entirely irresponsible and will most certainly doom the plan before it even gets underway. The protection of and the enforcement of existing (or revised) Rules and regulations regarding the use of the RF (wireless) spectrum should be the Commissions first priority; any economic benefits or gains resulting from the use of this resource should be secondary elements of the plan. Here's hoping you will deliver the public a responsible, well-thought-out plan. Good luck!

    TV spectrum is always threatened in these discussions. I suggest, since TV has already given up the 800 MHz and the 700 MHz bands to the gods of handheld wireless, we look now for ways to make users of other slices of spectrum in the VHF or UHF bands more efficient? Migration to digital transmissions for the FM band, taxis, public transportation, airports, etc., can open up quite a bit of spectrum too, just as TV has done.

    It is unseemly, I think, for the FCC to be playing in the hands of the subscription TV services.

Capture The Phone Numbers Using Your Camera Phone

If you have a camera and a 2D matrix code reader on your mobile phone, you can capture the FCC Phone numbers right to your phone by following these three easy steps:
Step 1: Take a photograph of one of the codes below using the camera on your mobile phone.
Step 2: Use your phone's Datamatrix or QR Code reader to decode the information on the photograph. Please note, these code readers are device specific and are available to download on the internet.
Step 3: Store the decoded address information to your phone's address book and use it with your Maps or GPS application.
