AT&T 5G Might Deliver 3 Gbps in Some Cases
AT&T says it now has more than 1,040 MHz of nationwide millimeter wave spectrum after adding 786 MHz of 39-GHz spectrum in Federal Communications Commission Auction 103. Prior to Auction 103, AT&T acquired 379 MHz of 39-GHz spectrum when it purchased FiberTower for $207 million in early 2018.
That means AT&T will have 800 MHz of 5G bandwidth in some markets, enough for eight 100-MHz channels. AT&T says it can deliver up to 400 Mbps of download speed per 100-MHz channel, reaching 1.5 Gbps across four channels.
So 3 Gbps should be possible, using all eight channels. Moreover, if a 5G device can simultaneously access AT&T’s 39-GHz and 24-GHz spectrums, or the 39-GHz spectrum plus low-band or mid-band channels, the speeds could be even higher, some believe.

It is worth noting that net profit margins in the retail grocery business are 1.44 percent, according to Damodaran. Mobile services might have slimmer margins than the notoriously thin-margin grocery business.
