This is the hype piece I had mentioned. On the plus side, T-Mobile is
driving cell phone manufacturers to make making mobile phones available to
operate in the 600 MHz band "at breakneck speed," as he claims, which is
indeed an achievement. What good was a band that no phones were designed to
use? But the forced use of a "5G" label, on something that doesn't even hope
to achieve the main objectives of 5G, is just propaganda. Just call anything
you like 5G, I suppose. Keep everything vague enough, you'll never be wrong.
Once again Bert is not comprehending Plain English. We’ve been over this
multiple times as it relates to what T-Mobile is doing. THey ARE NOT claiming
the initial deployment is 5G.
They are deploying cells in the 600 MHz spectrum with Massive MIMO antennas,
using technology developed for 4G LTE Advanced. And they have clearly stated
that these radios will be software upgradable to 5G when the standard is
finished and can be deployed in handsets.
This is EXACTLY what the following sentence, which Bert cannot understand, says.
"We're lighting up our new super spectrum for LTE and laying the foundation
for 5G so fast we're making the other guys' heads spin"
Then Bert doubles down on stupid:
The first part, okay. But "laying the foundation for 5G" is just empty
words. I'm laying the foundation for 5G by doing the laundry, because I said
so.
See above and all of the threads we’ve already exhausted that said what I said
above.
"They said it wouldn't be possible. They said it wouldn't be quick."
Not sure what anyone said wouldn't be possible. The "software update to 5G"
means what, exactly? Who knows?
It means that the radios employ the necessary technology to be upgraded in the
future. Apparently the real issue is just getting the 5G standard written, as
most of the technologies are now available and being tested. Kinda like the
fact that Samsung could achieve non-LOS service using reflected signals, with
little more than software...
One of the main goals of 5G is a much higher cell capacity, and no one, not
even T-Mobile, is making that claim for 600 MHz.
They most certainly made that claim. That is what Massive MIMO gets you Bert.
Look at the article YOU posted about the test in Amsterdam. You get major
spectral reuse within the cell since you are not radiating the same signal
everywhere, but tuning multiple antennas to limit radiation so that you can c
create multiple connections in that spectrum.
Take away massive MIMO and mm wave, or at least spectrum up in the multiple
GHz region where you can get really fat channels, suddenly what's left
becomes little incremental changes over 4G.
DUH.
That is why it is called 4G LTE Advanced. You are “taking away” the inefficient
use of spectrum (and power) and replacing it with much more efficient use of
the same spectrum, with the added benefit of using far less electricity.
"'The US has hit another milestone with the historic rollout of 5G-ready
technology in record-breaking time. The work we're doing with T-Mobile on
its low-band spectrum is paving the way for 5G in rural America and
nationwide,' said Börje Ekholm, President and CEO of Ericsson."
Uuuh, let's say 600 MHz LTE/4G evolution, in rural America. AT&T and
Verizon, on the other hand, are experimenting with brand new 5G concepts,
that differentiate 5G from 4G. T-Mobile will too, later, in their high band
spectrum.
They are experimenting with NON-STANDARD implementation for fixed wireless,
because they do not need to wait for the 5G standards - they are deploying the
devices needed at both ends (as they did with FTTH) and are making NO claims
that this is 5G or will be compatible with the 5G cellular standards. They are
simply saying that they are employing many of the same technologies that will
be used in the 5G standards...
Or in WiFi standards...
