Lightsquared rehash

As I understand it the issue is similar to the Lightsquared (now Ligado) fiasco in that it's about adjacent-band interference, but the concern is for altimeter equipment frequencies rather than satellite positioning frequencies.

The FAA knew well in advance the 5g rollout dates of cell carriers.?ÿ?ÿ

@flga-2-2 and they have been fighting to slow the roll the entire time. Both sides were acting like children. Now the public pays the price...

It is a potential frequency interference between some carriers mid band frequencies proposed for 5g use and aircraft instrumentation (specifically radio altimeters if I understand correctly)

It really isn't a 5g issue per se, but that is how it is reported.

Every carrier has multiple licensed frequencies. Every carrier is implementing a layered approach to 5g, with typically low band, mid band and high band (often referred to as mmWave). Date speeds increase with higher frequency, BUT range decreases. The much talked about mmWave for instance is very high speed, BUT very short distances, will be rolled out mostly at airports, stadiums, etc. where it is easy to cover a small area that has many people accessing the internet. Rural areas may only ever see low band.

The controversy currently revolves around mid band frequencies ONLY with certain carriers (AT&T and Verizon and maybe smaller players). T-Mobile is not affected, their mid band is a different enough frequency from those of concern with interference on aircraft that it isn't an issue.

So, not a 5g issue exactly, a frequency conflict issue for mid band with some carriers, but you really wouldn't know that from the news reporting.

I am operating at my home with T-Mobile on a nearby tower that already has 5G mid band, seeing speeds like this:

SHG

I didn't know 300Mbps was even possible.

I get 1.6Mbps on a good day with DSL and being 3.1 miles out on a system that only goes 3 miles without a repeater.

@jaro I had CenturyLink DSL, was a rare not offered any longer 100 down x 10 up plan. Was solid for the three years or so that I had it. T-Mobile recently started offering their Home Internet which is all over cellular. I signed up, and after a couple months ditched the CenturyLink DSL.

Yes the posted speeds are cellular speeds for the T-Mobile mid band frequencies and should be typically of everyone with a mid band device when in decent range of a tower. I have a tower about 1/2 mile away so I am in a good location. I assume once AT&T and Verizon can roll out their mid band 5G those users will see similar speeds. I bought a new 5G phone this year to take advantage of the low and mid band, the tri band 5G handset was another $300 and I figured that would see little use unless I am at an airport, etc.

I believe they are talking Gb download speeds at all the carriers with mmWave, but few of us will see that ever on a day to day basis.
