Verizon sprint t-mobile at&t be mad 

 

Experts at technology giant Samsung claim that they have successfully tested ultra-fast 5G wireless technology. 5G technology will allow users to download entire movie in just one second. Experts witnessed data transmission of over one GB per second from remote distance of two kilometers. The new 5G technology, which will take nearly a decade to replace existing 4G technology is capable of making transmitting speeds “up to several hundred times faster” than current 4G networks. Such a high speed network will allow users to transmit huge data files including high quality digital movies at very enormous speeds.

Old news.  It won't work.  In order to fit enough antennas into the device, they had to use too high a frequency to be practical.  Attenuation in building materials and even in foliage would make it useless without line of sight.  It's not "5G", it's just a new transmission method.  Referring to it as 5G was just a way to get people to read the article.  LTE has a LOT of headroom left in it for expansion within the spec (hence its name), so don't expect it to be replaced for many years.

But 5th generation back haul is ready.

it has been for years.  Multi-gigabit optical isn't a new technology.  Microwave wise, I can practically run 2 gigabit a few miles (with line of site) for under $10000 with my eyes closed.  That's not a new technology either.  The low price is new, though.

Yes, the price has dropped from 40k to 5K, which to me signals that its time for commercial communication.

Yeah, I think it's all cyclical though.  I was just looking at specs for a new device that runs 1Gbps over 50 ohm coax, fed by a GigE circuit, to extend the run distance at a lower cost than fiber.  Didn't we just move from coax to twisted pair about 20 years ago...

 

Or what about how everyone with multiple closely located sites was running 10-40Mbps microwave a big ago and then fiber got cheap enough that they started running their own fiber on leased space on utility poles about 10 years ago.  School districts and municipal services are a great example of this.  Now microwave is getting cheaper again, albeit still ugly if you can't hide the hardware.

 

I really do think that a lot of this is on about a ten to twenty year cycle, at least on the physical side of things.

    • Looks like T-Mobile just got an opportunity to expand n41 in Shentel-land https://www.fiercewireless.com/wireless/shentel-sell-its-25-ghz-spectrum-assets
    • Almost at 76% licenses "sold" at $160 million. Like watching paint dry.  Will check again in a few days. 
    • I guess we'll see how many takers there are for this: https://www.bloomberg.com/news/articles/2022-08-04/dish-nears-launch-of-mobile-service-taking-on-at-t-and-verizon One early drawback to the Boost Infinite service is that, for now, subscribers will need to buy a $900 Motorola Edge+ phone to get connected to Dish’s new network. More phones that are compatible with the system are expected in the third quarter, Dish told analysts Wednesday. Registration Site: https://www.boostinfinite.com I remember when Virgin Mobile went iPhone-only: https://techcrunch.com/2017/06/21/virgin-mobile-goes-iphone-only-offers-a-year-of-service-for-1/ That didn't go so well.
    • Hey Mike    Ya I was the one that brought the issue to your attn for the color thing on my 6T like 3-4 years ago   that was fixed after like 6 months  and I never had any issues with that anymore till the 1st  Android/OxygenOS 12 update but it hasn't done that anymore (that i've seen lately)   it just doesn't give me the  signal strength much anymore  it'll show it for like 5 mins then  switch to  "--"  and stay that way  Sometimes if I close it out and reopen it  it'll come back (tho the icon is delayed showing up for like a min  or so when it used to show up instantly) but after a few mins it's back to showing "--" again and other times it'll just come back to the "--"
    • Sounds like an awesome project—keep us posted on how it’s going! Also—if you’re able to figure out logging, I can work with you to get the data uploaded to SignalCheck.
