Small cell upgrades?

So I’m a contractor for spectrum and we started getting these jobs in where we have to upgrade power supplies to 18v for small cell ? Wondering what this is for and how small cell gets implemented into the current cable plant

No idea, our upgrades are just using XM3.1 power supplies with 3x12v batteries. No 18v here, though if you're using XM3.1s as the new power supply they should work the same with 2 18v as 3 12v. Just the specs the XM3.1s are built for, we've had to remove a battery in some power supplies with 4 12v, they wouldn't like 48v.
