@darkstarsats 4/x $NN) Low band carries the control signal that a tells a phone what to do. When to transmit data. When to switch towers etc. B/c low band travels farther than mid band, low band is needed to stitch together the network and make sure calls are not dropped / garbled etc.

@darkstarsats 3/x $NN) so while you are calling $NN's 15 MHz of low a "small slice" in reality it is not much smaller than what $T bought, and it could be multiples of what they have AVAILABLE
Laughing Water Capital on X
@darkstarsats 2/x $NN) This why $T bought 20 mhz of low band from $ECHO. $VZ and $TMUS have more subs than $T and about the same amount of low band. Logically, $VZ and $TMUS must also be dealing with low band congestion.
Laughing Water Capital on X
@darkstarsats 1/x $NN) you note that carriers "control" ~50 mhz of low-band each. respectfully, "control" is clearly not the relevant variable. how much they have AVAILALBLE is what matters. $T commented that they were capacity constrained on low band.

GameStop $GME just extended all stores hour to open earlier and close later. Wall Street suits are drooling all over their fat bellies and don’t understand foot traffic is through the roof.
