Re: [6gip] continueing the discussion on B5G

[Frank Fitzek <[e-mail]>]

Sorry

SA = Stand Alone (Real 5G networks)
NSA = Non Stand Alone 5G air interface with 4G networks


Most operators used NSA solution to get 5G to the mobile. So if the 
limitation is the EPC (or the connection to the EPC) , then it has 
nothing to do with 5G access.
