You make an interesting point because here Verizon and ATT are local telcos as well so they can potentially cannibalize some of their own customer based in their serving areas, but both have had wired broadband service options in their serv

Yes, Tmo is catching up with ATT and VZ on quality, the main reason they bought Sprint (remember them) is because Sprint had a shit ton of spectrum but they weren't building it out because they were capital starved (for a bunch of reas

Basically, 5G introduces some new technology that increases the so called spectral efficiency (bps/hz) that is how much tput you can deliver over the allocated spectrum. 5G introduces things like mm-wave tech using phased array antenn

One of the primary reasons that carriers are interested in 5G is because for the last decade they have been swapping spit (trading customers between each other, carrier A lowers the prices and take customers from carrier B, who responds in

Hi, another 5G UW user here, I am getting pretty consistently 1.8Gbps to 2.1Gbps on mine. But I played around with the CPE placement quite a bit. I don't know if you are able to try that. UW will drop you down to lower speeds or a lowe

Yes, each cell interferes with the next, that is call co-channel interference. That is a major factor that limits the capacity of a cellular network. There are a number of approaches used to manage that, carriers spend a lot of money and e

4G also reuses the frequencies in the exact same way, the primary difference between 3G and 4G is that 3G used CDMA and did not have the higher modulation desities, (capped at QPSK) while 4G LTE went up to 64QAM, so more bits per symbol. 4G

I have 5G at my house, I am served by what the provider calls 5G ultra wide band, which is deployed on mm-wave band (28Ghz) and uses phased array technology to implement beam forming, I generally get about 2Gbps on speed tests, but of cours

It most certainly did not do that, neither has 5G for that matter. The Shannon's Law refers to https://en.wikipedia.org/wiki/Shannon%E2%80%93Hartley_theore... to see the actual formula the basic principle is that

For the other 63%, I think an interesting possibility is to use a robot Turk machine type of arrangement. Take for example, the "flag person" at a road construction site, it is an outdoor job and hence would be categorized as not

I guess another question is if great professors are only at Yale or Ivy league schools? Here's something to consider, maybe not everyone needs a great professor, or an elite education, perhaps there are a large number of people who cou

OK, all sarcasm, set aside, will you divulge your relationship with Yale or other university with a large endowment? I sense some defensiveness.
316.
by zw123456 5y ago
OK, so if I am understanding your point correctly, education does and doesn't scale, and big universities with huge endowments have done enough because they put classes online and subsidizes tuition for a small number of lucky people.

I agree, there are limits to our understanding right now. Whether it is QM, or Dark M/E, etc. A lot of these constructs feel strained to me at times. But. having said that, I am guessing, that back when the cutting edge was Maxwell, a

Ya, in fact, I see very interesting formations all the time. One morning while making my coffee I looked out and saw what looked like a perfect flying saucer docked to the peak of the mountain. I snapped a photo and texted it to my BFF. She

Yes, I understand your nit picking about the "first" UFO sighting being Mt Rainier, although, I feel like it was pretty clear that wasn't the main point I was making. As for 1561, I am wondering if they had better optics and

And a big mountain with weird atmospheric anomalies around it. There are a lot of myths about Mt. Tahoma, the Native American name for Mt. Ranier. Probably because of the various atmospheric anomalies, or... who knows :) Just kidding around

When I was in college, I didn't have much money, like a lot of us when going to school, so I bought a beater bike at a garage sale for $5. It was a 3-speed type with big tires back before that became cool. The security mechanism was no

This is similar to what I call the "red sock in the wash theory". When I was growing up (back in the 1970's) my Dad insisted that my Mom do his shirts for him (back then all men had to wear a white shirt and tie to work). My
