Ping is round trip the minimum one way delay (end to end) to a geostationary satellite is 250ms, so 500ms round trip. Everything above that is processing delay, the TDMA modems and back end networks. For file downloads and video streaming applications the propagation delay is really not a factor, video takes a 400-500ms more to start buffering or for a file to start transferring. The major issue is jitter, keeping that low is essential otherwise video quality suffers.
I have tested ViaSat’s Linkway modems extensively. Appears they are using similar technology and software in their consumer modems. The delay and jitter they are advertising is very similar. VoIP and video works very well over Linkway TDMA links, but TCP suffers without some type of WAN optimization device. Most WAN optimizers use the SCPS protocol; assume this is what ViaSat’s consumer modem is using with some type of proprietary compression algorithm.
Ka works if you concentrate power in narrow beam widths with spot beams, which is what ViaSat is doing. Believe they are running margins in excess of 15dB with very good receive G/T at the satellite. The other plus of spot beams is frequency reuse; this is how they are accomplishing 140Gbps of throughput.
A stronger signal level typically increases the overall quality (BER), unless the noise level is changing comparatively. That is unlikely unless there is interference, so the bars are a good indicator of overall reception and call quality.
In the Consumer Reports video the iPhone lost 20dB by just placing a finger across the two antennas in the lower left corner, no death grip required:) Its true any object, hand, wall, rain, etc will attenuate a signal, but that is not what is causing the iPhone problem, it's the bridging of the two antennas. Steve Jobs is playing on the ignorance of the masses. The iPhone has an engineering flaw. If the death grip was the true problem then the rubber bumper would have no effect.

That about sums it up...
Regardless if climate change is true or not, this is a major fucking waste of time by the Utah legislators. Passing a bill certainly does prove climate change is false, thank "God" we don't need scientists anymore.

The bigger question everyone fails to ask... Is all this crap we inject into the atmosphere good for us humans? Most likely not! So why not change for that reason alone, regardless if climate change is true or not.
Its illegal for the U.S. to export these items too. So its not just Chinese law being violated here U.S. law is as well.
Sending your electronics to get "e-cycled" at a verified/certified company is no solution either. Many have been busted for exporting toxic electronics. Its all about making money...
Nothing in the article suggests information collected from WGA was used in this case or that it passed on personal data either. MS has visibility when pirated/counterfeit versions of their products attempt to certify as Genuine. WGA only prevents an illegal copy from receiving updates. Headline is very misleading!
A compiler could do the same thing as the CPU, convert x86 instructions to the native CPU microcode. However, you would lose backwards compatibility. Microcode is architecture dependent, so a higher level instruction set (i.e. x86) provides a level of abstraction for programmers and compilers. So itâ(TM)s actually a good thing.
On superscalar pipelined architectures there is no tangible performance hit when converting instructions. Even if the pipeline is flushed the performance hit only lasts for the next few instructions, until the pipeline is full again. Intel has done some remarkable engineering on the Core 2 processors that minimizes flushes and cache misses. Anyway, all modern processor that I know of convert their instructions to the CPUs corresponding microcode instructions (or microops in Intelâ(TM)s case). So whether its x86 instructions or some other type of instruction a conversion will occur.
To put your data into the proper perspective, the top 10% collect 46.44% of the income (2007). So if your data is correct, they represent 40% of taxes paid, that doesn't sound so bleak. http://www.taxfoundation.org/news/show/250.html
Anyway, to stay on topic those who want to watch OTA tv get your rebate coupons and buy the digital tuner from a reputable dealer.

Without a doubt some debris will accelerate into a higher orbit, but this will not affect all aspects of the debris path. The other side of the orbit, most likely the new perigee, will remain mostly unchanged. Atmospheric drag will still be a major factor in this part of the orbit. I'm sure the military is modeling the potential affects prior to creating 100s of potentially new space objects. Then again some military scientists speculated the A-Bomb might destroy the entire world yet they detonated it anyway.
Since this is a severely decayed orbit I would suspect most debris to reenter within the same timeframe or shortly thereafter, 1-2 weeks. I also doubt it will create any debris fields in a useful orbit. Anyway, the only reason the military would do this in the first place is to ensure a complete destruction of the spacecraft. Break it up into small pieces beforehand and the reentry will take care of the rest. Otherwise, why bother!
Or target practice?

Higher frequencies get attenuated by walls, rain, trees, etc... more easily than the lower ones. Yes the higher frequencies have more available bandwidth but there are disadvantages. TFA mentions the pros of using the UHF and VHF spectrum.

MS has a superior IDE with Visual Studio as compared to most, but I agree the underlying language is no different then any other.

So does this redefine the plain view laws?
What is network domination anyway? Is that anything like air superiority or superior firepower?

I will use my football analogy, you are 110% correct. People are confusing wavelength with bandwidth.
Higher frequencies get attenuated by walls, rain, trees, etc... more easily than the lower ones. Yes the higher frequencies have more available bandwidth but there are disadvantages. TFA mentions the pros of using the UHF and VHF spectrum.
