Re: Pushing for UNLICENSED spectrum is the problem
said by TKJunkMail  :.... But once these bands are opened to unlicensed devices, all hell can break loose. To expect all manufacturers to cooperate and make sure their devices work properly is a fantasy - especially with all the equipment coming from China.... they have these things called "standards" that work to prevent stuff like that.
plus, if the NAB starts screaming "interference" and can prove it, whoever is causing it is going to get creamed by the regulators.
right now, it's just broadcaster FUD about how this can't work. |

To expect all manufacturers to cooperate and make sure their devices work properly is a fantasy - especially with all the equipment coming from China. If these devices were licensed, I'd have less concerns. For once, I agree 100% with you and the NAB.
The PBS DTV station in my market is almost 50 miles away, and only medium power. To get a good signal requires a high-gain directional antenna 30 ft from the ground.
The "white space" proponents expect me to believe that some cheap device INSIDE a house, behind walls and AT OR BELOW ground level is going to be able to detect this distant UHF signal reliably. I don't believe it and no one can convince me.
But I sure believe that same indoor device will overpower and blank out my distant signal if the neighbor in front of my antenna fires it up on the same frequency, and I will not be happy about it.
And what happens when everyone gets them and all the strong signals are from other local devices?
The ONLY way white space will work without interfering is if it is licensed geographically to channels that are truly unused and unreceivable in that area.
A wireless ISP could be licensed for both transmit and return frequencies each tower is allowed to use. But even if these frequencies are truly unused TV frequencies then there is still a problem - what if I want to start a new TV station and all the channels are gone to wireless data service?
If you want to run a wireless ISP, stop trying to steal the TV bands for no money, you should be bidding on or leasing the frequencies the FCC already took away from TV to be reallocated.

said by TKJunkMail :Google is playing the "we are for the people" card again. We see how well that worked for the recent spectrum auction. I find it humorous how Google becomes more and more of a mouthpiece for consumers' network connections, but fail to follow through with action. Google is becoming a great PR machine as witnessed by the loyal "Google can do no wrong" followers around the Internet. Strange how these same people despise the other PR machines... |

1 edit |  Google makes a big deal about how spectrum sensing devices can allow all these devices to interact harmoniously in an unlicensed band of frequencies while not causing harm to nearby licensed frequencies. But once these bands are opened to unlicensed devices, all hell can break loose. To expect all manufacturers to cooperate and make sure their devices work properly is a fantasy - especially with all the equipment coming from China.
If these devices were licensed, I'd have less concerns. Google is playing the "we are for the people" card again. But what they aren't saying is that they are for Google ads and Google profits.
