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.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
