True for NCE (non-commercial educational stations. 47 CFR 76.55 Definitions applicable to the must-carry rules. (a) Qualified noncommercial educational (NCE) television station. (b) Qualified local noncommercial educational (NCE) television station. http://www.law.cornell.edu/cfr/text/47/76.55 47 CFR 76.56 Signal carriage obligations (a) Carriage of qualified noncommercial educational stations. http://www.law.cornell.edu/cfr/text/47/76.56 NCE stations do not have retransmission consent rights. However, full-power commercial stations have must-carry rights throughout their Designated Market Areas (subject to numerous exceptions). DMAs are defined by Nielsen Media Research and do not correspond to FCC contour maps. DMAs usually follow county lines but some large counties (e.g. San Bernardino County California) are split between two DMAs. 47 CFR 76.55 Definitions applicable to the must-carry rules. (c) Local commercial television station. http://www.law.cornell.edu/cfr/text/47/76.55 47 CFR 76.56 Signal carriage obligations (b) Carriage of local commercial television stations. http://www.law.cornell.edu/cfr/text/47/76.56 Full-power commercial stations also have retransmission-consent rights. 47 CFR 76.64 Retransmission consent. http://www.law.cornell.edu/cfr/text/47/76.64 > Bear in mind, though, that must-carry is normally only invoked by > stations that aren't particularly desirable.

However NCE stations do not have retransmission consent rights. Neal McLain|

Here's some more information about iBeacon: http://en.wikipedia.org/wiki/IBeacon It doesn't go into much detail about this, but I gather that Bluetooth Low Energy doesn't require the devices to pair with each other explicitly. It seems to be the same technology used for using a smartphone to pay for something by holding it next to the POS terminal. The beacon simply broadcasts its UUID, and the mobile device may send back its UUID in response. For many uses, the device doesn't have to respond -- the iBeacon-enabled application uses the beacon's UUID to determine its location, and display appropriate information or ads. The way you're tracked isn't by detecting the device directly. Rather, it's because the application needs to look up the beacon's UUID over the Internet, to find out what it should display. The server that provides this information can record information about which device queried it, and which beacon it was looking up. -- Barry Margolin, email@example.com Arlington, MA *** PLEASE post questions in newsgroups, not directly to me ***|

Hopefully the app allows you to opt in/out of using this (unless, of course, that's the only point of the app). - - Barry Margolin, firstname.lastname@example.org Arlington, MA *** PLEASE post questions in newsgroups, not directly to me *** ***** Moderator's Note ***** Since the company serves multiple cities, including mine, please tell the readers how to spot "beacon-enabled" aps.

Subject: New York City orders tracking devices turned off Message-ID: <20141007163637.GA28099@telecom.csail.mit.edu> After BuzzFeed revealed late Sunday that a digital advertising firm, Titan 360, was using public pay phones in New York City (yes, they still exist) to host Gimbal Bluetooth tracking beacons, the mayor's office has now ordered them to come down. The beacons can be used to log nearby phones. Bluetooth addresses and mark the date, time, and location where they are seen. As such, the beacons can be used as a way to track physical movements of cellphone users, potentially allowing advertisers to serve those phones customized spots. (Users who have Bluetooth turned off on their phones will not be seen by the beacons.)

Look up BTLE ("Bluetooth Low Energy"). It's a somewhat different beast than "classic" BlueTooth.|

Well, not really shunned. There's just been no opportunity to license that spectrum for cellular. The older IMTS (pre-cellular wireless telephone) systems operated at 450 MHz or so. There is also the problem of substantial man-made noise in the VHF band. The incentive auction process will free up some spectrum at 600 MHz for wireless. There's an extensive discussion of issues such as filtering and antenna bandwidth in the technical appendix to the FCC order regarding the incentive auction. (FCC 14-50 Report and Order in GN Docket 12-268). "Modern research is looking at much higher frequencies for wireless. We already have Wi-Gig (60 GHz). People are proposing using millimeter waves for commercial wireless." "Over 20 GHz of spectrum is waiting to be used for cellular or WLAN traffic in the 28, 38, and 72 GHz bands alone, and hundreds of gigahertz more spectrum could be used at frequencies above 100 GHz." [from Rappaport, Theodore S.; Heath, Robert W., Jr.; Daniels, Robert C.; Murdock, James N. (2014-09-09). Millimeter Wave Wireless Communications (Prentice Hall Communications Engineering and Emerging Technologies Series) (p. 3). Pearson Education. Kindle Edition.] Fred Goldstein wrote: > The other problem is bandwidth. TV channels are 6 MHz wide, and the > whole VHF range is not all that big.

That > again points to higher frequencies. Right, as the quote above from Rappaport et al. points out, if you want GHz of bandwidth, you have to go to much higher frequencies. Wi-Gig claims data rates up to 7 Gbps. But, as I understand it, the Wi-Gig systems deployed today can only reach about 4.5 Gbps. (Only 4.5 Gbps!) But, that is in a 2 GHz+ bandwidth channel. Chuck ***** Moderator's Note ***** The IMTS system used both the 150 MHz high-VHF band, and the 470 MHz UHF band. There was also an older manual system, called "MTS", which operated in the 40 MHz region. The UHF units were only for IMTS, but VHF IMTS mobile phones could be used in areas that still had only manual service. Bill Horne Moderator|
