Re: Don't cater to more corporate cry-babies
Well, if I read the article right, the satellite companies are operating in or around 2400 mghz (or 2.4 ghz) and this is UNLICENSED spectrum.
Correct me if I am wrong concerning their operational spectrum, but I think I read it right.
If that's the case, then my argument is how they might expect to get the FCC to try to regulate UNLICENSED spectrum, with their favor skewing the regulation of the spectrum.
It seems like a selfish attempt by these companies to try to regulate spectrum that everyone has a right to use.
This is why you have everything from Wi-Fi to cordless phones operating in this spectrum.
Besides that, these companies may not even be able to stay solvent long enough to justify any of these moronic regulation attempts. They may not have enough money in the bank to bribe Mr. Powell either.

Not exactly....It's a SHARED band, and the people running unlicensed (Part 15) devices are required to do certain things, under certain circumstances. Example....I fire up my 15W 2.4GHz Amateur Radio transmitter, and knock your WLAN off-the-air. Gee, that's too bad for you. I have a license, and you don't. If your WLAN (or 2.4GHz telephone)interferes with my AO-40 satellite downlink, I can request that you turn it off, or not use it during certain hours. Of course, the chances of: 1)Finding you, and 2) Getting you to understand what Part 15 requires of you, are both exceedingly small, so you never hear of a Ham doing this. These guys, however, have some serious MONEY and LAWYERS to do their talking for them, and as such, can get the attention of the media, and more importantly, the FEDS. I recently read a design review of their system in one of my RF trade mags, and it's laughable. It's poorly designed, the silicon they use in the receivers is NOT ready for prime time, and their ultimate signal-to-noise ratio is something like 6dB....pretty poor. So, they p*ss and moan to their Congressman and stockholders, and try to get the rules changed to allow their system what amounts to an extraordinary level of protection from existing services.
I hope they fall on their a$$!

Ok. Yes, it is incorrect. They do NOT operate in the unlicensed spectrum but in licensed spectrum that they obtained from the FCC and licensed to them. The 'operating IN or AROUND' is a big difference. They don't operate IN the unlicensed spectrum, but their licensed frequencies are AROUND, ie. close, to the unlicensed spectrum.
That said, I don't agree in any way what they are attempting to do. They need to develop their radios and directional antenna to reject off band transmissions much more than they do according to some engineers reports. If there ARE some devices in the unlicensed spectrum that are causing major spurious transmissions in other bands, then they, and they alone, should have their equipment adjusted and modified just as any manufacture of equipment capable of transmitting would be required to do. But to change the entire specs of the unlicensed spectrum is absurd. That's like a holder of one license saying that if harmonics from any other transmission interfere with their frequency, no matter if they do nothing to prevent the interruption in their (the license holders) equipment to reject them, then everyone has to modify or recall their equipment. (And they'd probably be holding their equipment 2 inches from the antenna of the supposedly offending equipment.)
What has me scratching my head is that this is coming up now. If I recall correctly, they aren't claiming there's a problem now, but there would be as more use the frequency in the future. Why didn't think think of this before when they were designing their own equipment or when they bid for licenses? They may say (and I believe have said) that there wasn't much in the 2.4 ghz band used at the time.. But that doesn't seem to fly. They had the history of the 900mhz unlicensed spectrum and that went gangbusters with wireless devices. It seems they should (being the operative word) have taken the nearby unlicensed spectrum into consideration from day one. IMHO, this seems more like poor planning and now trying to get out of it after spending hundreds of millions. I'd personally think they'd be better off trying to get some subscribers with what must be a huge burn rate on cash at this point. If they don't they'll go under and not have to worry about anybody causing interference from any frequencies. | |

| Thanks for pointing those points out. I agree with you.
I think it's ridiculous also to try to make up for shortcomings in design engineering in your own equipment by trying to force regulatory agencies to force others to modify theirs.
It's moronic.

| Even though it is licensed, the whole thing shows you how moronic the FCC is. You have an existing "unlicensed" spectrum that you *know* will be "dirty" (full of cheap consumer equipment that shoots out harmonics beyond the center frequency) and someone comes along looking for some space in the "2GHz neighborhood"... So they give them something exactly adjacent to the unlicensed band. Duh.
Kind of like being the proud recipient of the band right above the CB band... "Here's 28MHz, have fun! Don't mind the trucker over there shooting out a kilowatt at 27MHz!"... | |

| Yeah, but is there anybody in the FCC contacting all the CB radio manufacturers in order to have them redesign all their equipment in order to satisfy the inadequacies of another vendor's equipment, just because this manufacturer whined to Powell about it?
I think not.
If the FCC allows this to happen, then it would just be another example of how "in the pocket" guys like Powell can be.
It's corporate tea-bagging.
