RE: home router battery backup

[Shawn L via NANOG <nanog () nanog org>]

In $dayjob I work for a telco that deploys fiber to the home.  If we are providing voice services over fiber a battery 
backup is installed (we maintain) that powers the customer's phone in the event of a power outage.  It does not power 
their router, etc.  99% of the customers do not install a UPS for their router, etc.  We try to explain that to 
customers, but we still get calls that they can't get on the Internet when their power is out.

Subject: home router battery backup




Hi NANOG mailing list,
 
I am a graduate student, currently conducting research on how power outages affect home Internet users. I know that the 
FCC has a regulation since 2015 (47 CFR Section 9.20) requiring ISPs to provide an option to voice customers to 
purchase a battery backup for emergency voice services during power outages. As this is only an option and only applies 
to customers who subscribe to voice services, I was wondering if anyone had any insights on the prevalence of battery 
backup for home modem/routers? I.e., what percentage of home users actually install a battery backup in their home 
modem/router or use an external UPS?
 
Thanks.
Scott
