[HELP a Network Noob] What does 20+20 mhz LTE mean?


Recommended Posts

Hello~!

 

I read an article about T-Mobile rolling out 20x20 MHz (20+20 MHz) LTE to select cities and I realized I have no idea what 20+20 MHz LTE means.  :P  I performed a Google search but I can't find any articles that explain the differences between 5x5, 10x10, 20x20, etc. 

 

Can someone explain what this terminology means or link me to an article that explains all this stuff?

 

Thanks.

20 + 20 is carrier aggregation of 2 20mhz LTE carrier.

 

20x20 is FDD-LTE designation for 40 mhz of spectrum with 20 mhz for downlink and uplink.

    • Well, I saw a good deal on a factory unlocked A32 5G on eBay and was able to convince the seller to show me the software info screen--and it was May.  So I jumped on it. Stuck one of my Tello SIMs in it, and while my Moto One 5G Ace would connect to n71 SA, this phone refuses to do so.  And with only 0 for the TA value, it's less useful for LTE than my older devices.  Oh, and the *#2263# menu doesn't work properly for NR.  So definitely glad I'm able to disable updates. - Trip
    • NextWave re-emerges with 2.5 GHz private network service  https://www.fiercewireless.com/private-wireless/nextwave-re-emerges-25-ghz-private-network-service https://www.nextwave5g.com/nextwave-news The only way for T-Mobile to get up to 190MHz now is to either buy out NextWave in it's entirety or wait until NextWave's lease is up and attempt to "outbid" them for the right to lease the spectrum from the Archdiocese.

    • Mike. I sent in more diags for wi-fi 6e yesterday where SCP shows channel = 0.  Thanks.
    • Added and modified them all! I took a trip through the L train tunnel between 1st Avenue and Bedford Avenue recently and found n41 live in the tunnel. It's 80 MHz, speeds were 250-300, and I didn't have time to check if n71 is there. Some stations speeds slow wayyyy down when a train pulls in now, even the ones with B2 at 15 or 20 MHz, so any upgrade is great sight to see.
