I did wonder that too. RCG is 3G/4G only though (and those two sites you mention are 4G only) unless RCG has used this as a opportunity to experiment with 5G/NR.

I spotted one part of AT's video (0:45-0:50) where I saw there are separate racks for Spark and One/2degrees which makes me wonder if there is MORAN involved for One/2deg or if it's just bad labelling and 2deg does have their own gear.
