Comment Re:If Apple owns the patent (Score 1) 133

That's a fair point. It very much feels like patent abuse to obtain if the sole purpose is to deny the technique to competitors ...

Pardon me for being Captain Obvious here, but that is exactly what patents are intended to do! Patent confers intellectual property rights to the patent holder. What that patent holder chooses to (legally) do with those rights is completely up to the holder.

Haven't you ever heard the conspiracy theories about stuff like Goodyear buying the patent for a 100,000 mile tire? Or GM buying the patent for a 100 mpg car? Or the best yet, the Gubment buying patents to keep technologies out of the private sector?

Remember, before you say "pshaw!", I did qualify all of these as "conspiracy theories." The best conspiracy theory is one that is unprovable, yaknow.

Oh, and I do agree with your conclusion. Apple could be trying to keep this out of the hands of other "less ethical" companies (you know, ones that do no evil...)

Lately I have become so frustrated with my Nexus 7 updating (and becoming essentially useless until update completes) that I am seriously contemplating getting an iPad mini just to escape Android! The only things I do with it are read Kindle books and play mahjongg. I do NOT need Google apps updated on a daily basis. Most of them I don't even know what they do!

One of the Part 15 rules is about not interfering, and clearly that's not working out so well.

I don't believe the FCC cares about Part 15 devices interfering with other Part 15 devices. From the rules:

CFR 47 Part 15.5

(b) Operation of an intentional, unintentional, or incidental radiator is subject to the conditions that no harmful interference is caused and that interference must be accepted that may be caused by the operation of an authorized radio station, by another intentional or unintentional radiator, by industrial, scientific and medical (ISM) equipment, or by an incidental radiator.

(boldface is added for emphasis)

In other words, a Part 15 device that interferes with another Part 15 device is cool, since Part 15 devices are offered no protection from interference, intentional or unintentional.

The law is written so that Part 15 devices are not allowed to interfere with licensed devices.

Comment Re:Clarifications - MOD UP (Score 1) 47

On the basis of trusting that the AC truly is one of the authors (of the scholarly paper), I want to thank you for these clarifications and suggest to all to mod that post up. It definitely is better than score: 1, which is its current value at the time of my writing.

110 dB of SI cancellation is beyond impressive - it is approaching magical!

On the face of it, this capability will double capacity of any RF channel for which it will work. AC claims this can be made to work on channel bandwidths exceeding 20 MHz, therefore making it useful for WiFi.

But I think there are other advantages. If a traditional system uses FDD (frequency division duplex) to achieve duplex (simultaneous transmit and receive) operation, then this new technology reduces by half any discrete RF/IF filter hardware needed to reject out-of-channel energy. That will help make the electronics simpler and less expensive. For FDD, the cost of the filters goes up as the two channels (transmit and receive) get closer together (the closer TX is to RX, the steeper the filters have to be to achieve adequate rejection). With this all-silicon approach, the most you need is bandpass filtering for the ONE channel you are using. Big win!

But then maybe I am exposing my dinosaur-like thinking in even bringing up discrete RF filter components. A recent announcement at Mobile World Congress touted a silicon-only radio technology that didn't appear to need any discrete filtering at all.

Also my (dinosaur-vintage) thinking about cellular base stations is that they generally operate in the +40 to +50 dBm range (out of the PA, prior to duplexers, etc. and not considering antenna gain), which implies another 20-30 dB isolation is required (vis-a-vis the AC's claim of 110 dB) to achieve the same isolation one would need in a cellular system. But then I'm not considering antenna gain which seems (without thinking about it too hard) to potentially improve the isolation if separate TX and RX antennae are used at the base station. Then again, I'm thinking macrocells here. But for a single channel duplex RF technology to be deployable in cellular, I think one would need to cover the macrocell case - in any case.

Next to that, we need a system of converting CO2 from the air into a usable fuel, ideally propane, because propane is not a greenhouse gas and inert.

Really? My reading is that the equation for propane combustion is: C3H8 + 5O2 = 3CO2 + 4H20

Maybe propane produces less CO2, pound for pound, than say, coal. (I don't actually know, and don't care to look it up.) But it certainly produces CO2 when burned.

Oh, and anyone who's ever cooked on a propane grill, or used a propane torch, will attest to its distinct non-inertness...

Unfortunately, a small, aggressive, well-funded minority can always subvert the democratic process.

If by this, you are obliquely referring to the NRA (as the aggressive, well-funded minority), you might take note that right now in Washington State, billionaires are out-spending the NRA (and pro-gun overall) by a ratio of 7 to 1 on an initiative to expand background checks. Well, at least that is what they are calling it. It's a whole lot more than "simply" expanding background checks, but I digress...

Said billionaires include:

Bill and Melinda Gates, Paul Allen, Steve Ballmer (gotta love all that Microsoft money slushing around)

Nick Hanauer

and Michael Bloomberg.

I particularly thrilled at how Ralph Fascitelli of Washington Ceasefire recently invoked the imprimatur of Dan Satterburg (King County prosecutor) as a supporter of I-594, while not mentioning the rest of the state (King county is a little over a quarter of the state's population). This was, of course, to a Seattle audience (who would care about the rest of Washington's population - how?).

Wi-Fi is not a wireless communications standard. IEEE 802.11 is the wireless communications standard. Wi-Fi is a registered trademark of the Wi-Fi Alliance - and industry trade organization. They do publish interoperability agreements and offer "certification" (required to use their trademarks on products), but these should not be confused with the IEEE wireless communications standard.
