Stop Cell Phones Without Stopping Pacemakers...
metoikos writes "A company based in Fairfax, Virginia, has come up with a subtler method of
preventing cell-phone addicts from using the world as a phone booth than a faraday cage or even those little hand-held jammers.
Cell Block Technologies (that name must go over well with law enforcement) is developing a smoke-detector sized device which sends signals of 'no service' to cellphone frequencies, prompting phone to send calls directly to voicemail.
Admittedly this is better than messing with everything that uses the same frequencies cellphones do . "
It's too bad nobody's developed first-post blocking technologies.
In Soviet Russia, link follows you!
Soylent Green is peoplicious!
Is it illegal for a business establishment to 'fence-out' unauthorized carrier frequencies? Do you have jurisdiction over the entire spectrum within your own property?
Typically, in other countries, devices like this (jammers)are already used in theatres, concert halls, etc to stop cellphones from ringing during performances. A device like the one in the article would not interfere with a pager, which is typically what doctors, police, etc use. If you have a grinding need for your cellphone to work, its typically posted that a jammer is in place, so you always have the option of not going to see that movie or that concert.
slashdot, news for crazed liberal socialist zealots
And you can't get your babysitter to call the restaurant?
How did your parents ever survive without a cell phone?
The fact is that you don't NEED the phone to work everywhere, you just WANT it to. There's a big difference.
It isn't your airspace. It's a public place.
If I put forth the expectation that all guests are treated equally,
First of all, there is notthing inherently "equal" about preventing cell phone signals. Second of all, your "expectation" isn't binding on anyone else. I expect my cellphone to work when I am in a restaurant or theatre. I pay for it to work there. Tough beans for your expectations.
Why? Because people all around you paid for a show.
There is nothing in the silent vibration of my cellphone that anyone around me will notice. If they notice me pull it out of my pocket and look at the screen, then it wasn't a very interesting show and you owe them their money back.
I may be stopping your right to receive a call, but if your phone is licensed in the US under our FCC laws, your phone must accept any interference, which may cause undesired operation.
This is the reason I bothered to respond to your selfish little rant. You are patently wrong. Primary licensees do not have to put up with any interference, they have the primary right to the frequency, and deliberate interference is illegal and can subject the interferer to heavy fines.
What you are probably thinking of are Part 15 unlicensed devices like Wi-Fi or cordless phones and baby monitors. Those devices are not licensed any they do have to put up with interference from licensed users of the spectrum and each other. For example, as an amateur radio operator, I am a primary licensee in the 2.4GHz Wi-Fi band. If I decide to put up a station on one of those frequencies, I can do so, at a much higher power than you can ever hope to override, and YOUR use of the spectrum goes POOF!
I am a SAR volunteer, and my cellphone may be how I am notified that there is a lost child that needs to be found. I'm sorry if you think that your right to silence overrides the life of another human being, but get over it. If my cellphone vibrating in my pocket annoys you, then get your fucking hand out of my pocket and mind your own damn business.
