  1. Re:Long term on Apple, ARM, and Intel · · Score: 1

    You get into RISC vs CISC arguments here. There are only sample quantities of 64-bit ARM at this juncture. There's really no good reference model when you start going that direction with ARM.

    Intel isn't paranoid enough to survive, methinks, and will be left behind.

    And the scale you'll see is already here; SeaMicro is doing it, and HP will do it if they can get Project Moonshot off the ground.

    Transistors are one measure, an important one, but design ease and getting work done is another. Ultimately, power consumption will become an even larger quotient than it is now. Intel fixes stuff differently than ARM designers do, but if the market does walk away from x86, they're a one-trick-pony.

    The range problem is an illusion. The output to the antenna(s) is the same. The radial or omni-polar radiation doesn't change. What changes is that newer hardware is faster.

    Should you take a field-strength meter and walk around the area, noting the polar strength, you'll see that it doesn't change in two, three, four, etc years.

    Can you reduce the coverage area? In certainty! Block the antenna. Add paint, drywall, furniture, or anything else but air (even relative humidity has a bearing on the distance). If you use 802.11a or n-high then its penetration radius is much smaller as the transmission characteristics of 5Ghz isn't nearly as nice as 2.4Ghz. There power limitations and antenna limitations (technically self-imposed by the vendors) in the 5Ghz transmission devices that limit effective radiated power. If you get a signal, it's sometimes by reflective rather than direct means as 5Ghz has a short-range bouncing effect.

    The same AP on the same freq/channel using the same transmission modulation technique (there are more than 25 different types) will yield the same effective radius given the same antenna and receiver. Other items change, as noted, that give the *appearance* that things slow down. The APs don't "age", and the device inside your notebook or USB-WiFi adapter don't change. At best, on a bad day, you might get oxidation on the TNC or other coaxial (if present) connector for the antenna on a 2.4Ghz device. Otherwise, it's not going to change electrically, and so the slow downs are perceived, but the source of the perception isn't a geriatric or entropic device combination.

    It's not so simple. Let's review the history:

    802.11a was first (there is another but obscure predecessor), and used 5Ghz. Advanced modulation techniques blew the doors off 802.11b @2.4ghz, which at 11mbit/s (on a good day), had a very low yield.

    802.11g also uses 2.4ghz, but early products had trouble going back and forth between b and g, thus slowing throughput down, despite faster yields in g via advanced modulation techniques.

    Enter N, was an advanced modulation scheme with higher throughput, first largely found on 2.4ghz. At first N was really fast, and had only a bit of trouble SLOWING DOWN for b and g. You have one collision domain unless you break out the b/g radio with the n radio. So, you have to dawdle while b goes through, then the channel is free again for something faster.

    Then come the dual-band radios, and the dual band, dual radio routers which can walk and chew gum-- and handle paralellizing a 2.4ghz and a 5ghz conversation simultaneously-- major thruput.

    The transceivers in the older routers appear to slow down, but in fact, they stay the same compared to newer ones for three reasons: 1) better firmware design that can switch back and forth quickly between protocols (where present) 2) have dual radios for bgn and (maybe a)Highband N and 3) the more recent the device, the more likely it has faster processing power inside the router. The final reason is that your backhaul might be getting faster without you knowing it; DSL gets faster but so also do cable broadband connections. And it's likely the driver in your machine is faster; they change all the time with small improvements, sometimes in real throughput.

    Summary: the router didn't change, but newer stuff is faster given the same conditions for the reasons stated.

    First, you need to use a modulation scheme that allows intense amounts of data exchange. If you don't do that, you're not trying and what did you do this for in the first place?

    You have to have pairs that are either lambda or phase delineated for rational discrimination. Then you need plenty of pairs, as this is a crossbar arrangement; otherwise it's useless and you might as well use RS-232.

    Finally, if you don't provide optimal switching, you're blocking, and if you're blocking, you're not state coherent, and why did you do this in the first place?

    What you say is, true, despite the humor. Let's say there's nice low power low noise wireless. Multiple concurrent channels would have to wired in a method that's like a cross-bar L2/L3 switch to make this work, and the matrix (sorry for the word choice) would have to service each point with non-blocking architecture as the bottleneck built in cache could be enormous and fast.

    Unless you can remodulate or make incredibly dense modulation possible, LED transmitters can manage about the same data rate as you see in WDM, and so the data rate among hosts isn't quite so chill. Power would be low, and it would be tough to find background noise to foul things up. But eventually, you'd need to have alternate spectra to modulate (lambdas) and tight tranceiver pairs to make it work. Your engineering cost just shot your low-cost.
