> Wireless is way too slow<p>Way too slow for gigabit internet, not way too slow for what most people actually need.<p>T-Mobile LTE in one city had an average of 28 Mb/s, enough speed for Netflix 4k, and 95 Mb/s max observed speed. I hate to support cable monopoly arguments in any way, but really for most people 100 Mb/s <i>is</i> overkill.<p>Of course the cell network couldn't support everybody's internet use with the towers covering such a wide area as today, but wouldn't fiber to the neighborhood and then wireless within it make a lot more sense than running expensive cable to every individual house? It wouldn't be gigabit, but if I could use uncapped tethering (due to smaller tower coverage area) that would be fine with me. T-Mobile LTE is plenty fast enough for anything I use the internet for.
Maybe I am doing the math wrong, but I think the plot "Minor Violations of the Laws of Physics" has the Shannon Limit 2x smaller that what it should be.
According to [1], for each 2x increase in SNR, the limit should increase in a full Bandwith.
However, when we compare the plotted values at 45db and 60db, we see that SNR increased 15db = 5 * 3db => 2^5.
That way, the limit should increase in 5 bandwidths.
But the plot increased from 300Mbps to 400Mbps => 100Mbps.
Hence the plot was made with a bandwith of 100/5 = 20Mhz, instead of the 40Mhz mentioned.<p>[1] <a href="http://en.wikipedia.org/wiki/Shannon%E2%80%93Hartley_theorem#Statement_of_the_theorem" rel="nofollow">http://en.wikipedia.org/wiki/Shannon%E2%80%93Hartley_theorem...</a>
