Verizon n77 range

Hi, I'm in the NWA region and I've noticed that Verizon's n77 range is much worse than ATT's despite being on the same tower. Verizon isn't on the top rack, but the antennas are pointed in the same direction as ATT. Despite being a little less than 1 mile away from the tower, I am unable to get n77 in my house on Verizon while I can on ATT (getting ~600mbps). Closer to the tower, the SINR ratio on Verizon is lower than ATT's SINR despite having the same RSRP value. Is this because Verizon is purposely turning down the power of the C-band antenna to compensate for the slower backhaul or will Verizon need to build another tower?
