even if 1800mhz is being deployed alongside 700mhz, 1800mhz will have a far smaller reach due to higher frequency, and I dont think all carriers will be deploying 1800mhz with 700mhz
That's what I've found in practice. 1800 seems to only go for a few kilometres at best, with poor penetration into buildings, whereas 700 can go for 20km or more, depending on the terrain.
It depends a lot on the Azimuth as well the site is set to for signal reach and you don't want 1800 extending for 20km
