| | | I would say other 2 years before you see that it happen because that happen to the wimax 3.65Ghz system. | |

Because the future everything will be broadband heavy requiring 3+ meg download. This is the 1st generation stuff. Carlson Wireless already has a TVWS device that will go up to 12 megs in a single channel. Start bonding multiple channels together and the speed will increase quickly, especially if the FCC allows them to use the full channel width on overlapping channels. | |
|
| | | But again it probably take 2 years before the public like us wisp can even use the space just like how the wimax took forever to get released to wisp's. So I would say its going to be a dead technology just like how BPL was. | |

Good for those stuck with satellite but not much more.

1 recommendation | Nice PR piece Karl must be reading from Genachowski's script. I give it about a month before it turns into another BPL gimmick.
This will fail too. Just wait.
And by the way, "White Space broadband uses the unlicensed spectrum freed by the transition to digital television" is incorrect. It shoves more unlicensed noise into an already crowded band that Julius fully intends to make even more crowded. | |
|
|
1 recommendation | Re: Nice PR piece Didn't King Julius and Obama want to take all of the UHF spectrum eventually?
This essentially leaves white space noisemakers dead in the water, IMO. | |

| | Would love to try it! My parents live in a valley where they can't get DSL, cable, 3g/4g. All the other wireless technologies are pure line-of-site. I'd love to see what kind of bridge I can set up between them and me over 145-225 MHz. That has the potential to be some chocolate-covered awesome. Any idea what they'll cost? | |

Chesterfield, MO | If it's line-of-site, why wait? There are existing point-to-point wireless bridges. They aren't terribly expensive (~$1,000) and they'll easily bridge several miles at 100Mbps full duplex. A quick Google revealed this possibility: »www.gridconnect.com
I'll bet more searching would find something even cheaper.
If you are technically inclined, you could also get by on the cheap by using high power 802.11 devices coupled with high-gain, directional antennas. Check out this site for high power equipment: »www.engeniustech.com | |

Chesterfield, MO | Re: Would love to try it! Check out their 900mhz bridge. It might do the trick. It doesn't need LOS. The lower frequency will penetrate obstacles. It still won't go through a bluff/mountain but it might bounce around a few hills. | |

| Antenna size? My main concern is the antenna size for the longer VHF wavelength.
When people speculated about using the lower VHF for cellular I envisioned a cell phone with a 32" whip.
I should note that many of the OTA broadcasters moved their DVB back down to VHF after the transition. In my area, at least the upper VHF, channel 9 to 13 is used for DVB in addition to several on UHF. When I first started watching OTA DVB, I only needed a UHF antenna. There's no such thing as an HD antenna or digital antenna as most probably know. | |

VHF for digital is prone to interference. Espeically low-VHF which is why so few use it. Those that do are trying to get on UHF. hi-VHF isn't much better. Hi-VHF can get interfence from 2nd harmonics so if you have some strong FM stations in your area that can effect hi-VHF channels. | |

All our TV and FM towers are all over the place in the Puget Sound Area. Interesting though is that the second harmonic you stated would indeed fall somehwere in high VHF from a given frequency in the 20mhz FM band. I know when we're talking millions of watts of FM transmitter power a second harmonic can indeed be strong as well. I actually liked it when all DVB here was UHF. | |

MHz 145 to 225
MHz 210 to 470
MHz 470 to 930
Consdiering verizon and at&t owns much of the spectrum from 698-930 I think they'll have a bit of an issue with this thing potentially causing interference. These deices might have permission to run in the TV spectrum but that ends at 698. So why did they FCC approve a device that runs higher than that? | |

| | White spaces Guys, the gear they are releasing, and it's usage is for commercial applications. You wouldn't be purchasing this stuff for trivial links for your home or neighbors. We are talking big money to buy it in most cases. Or big enough you wouldn't pay for it.
Also, If I am not mistaken, the gear has integrated channel assignment via a nationwide database. You can't just pick whatever channel you want to use if I understand correctly. The gear does it for you to make sure you don't interfere with a licensed user.
It is not typical WiFi.

My point is I've seen the data bases and they are off. They fail to list most of the nashville TV channels in my area. Yes they are weak but many people can get them in with some effort. Since they are weak to begin with it wouldn't take much for this device to cause interference if someone uses a TV channel that didn't appear in the database but in fact does exist. | |

Camden appears to be located outside of most Nashville DT broadcasters' respective noise limited service level contours (28 dB for low VHF, 36 dB for high VHF, 41 dB for UHF). If so, I do not believe that the broadcasters (nor, by extension, the viewers) are entitled to protection from interference because Camden is out of market.
You can view the Nashville DT broadcasters and their service contours at the FCC site:

These devices can make OTA signals completely unwatchable if some moron uses these devices on a TV channel in my area. Thus FORCING people here to have to pay for cable or satellite. The FCC knows this wil happen in many places. They want to kill OTA TV and thus by making it harder to view and forcing people toward pay TV services they can steal spectrum and give it at&t and Verizon. Too bad not too many can see this scam for what it's for. | |

First, lose the pejorative tone, both toward me and the FCC. This is not some grand conspiracy to take away your OTA DTV.
Now, did you read what I wrote in my post? Did you understand the concept of service level contours? Did you view the contour maps from the FCC database that I linked?
Camden is outside of the established service contours for six of the eight Nashville DT stations. If my understanding of FCC broadcasting regulations is correct, then those six DT stations are not entitled to interference protection in Camden because Camden is outside of their licensed markets, respectively. That you may be able to "DX" some Nashville DT channels beyond their service contours is nothing more than serendipity and not entitled to interference protection.

It's a black box SDR, which needs a host PC to configure and probably to operate in any advanced digital manner. Depending on the applications running on the host computer it can be any of a number of Advanced Wireless doodads.
