You can use the same hardware.
However it’s a big uplift to go from standard Residential @ £75 per month to Priority 1TB which gives you a public IP address @ £180 per month.
I’ve now downshifted mine to a more wallet and backup friendly £8 per month (Roam 20 GB) - I knit my networks together using ZeroTier so it all works seamlessly.
The geographical location served remains connected with three PSTN lines each of which has an usable upload speed. We did think about bonding but at the time STARLINK became a viable alternative but frustrating without a fixed IP. DDNS comes with security concerns for the transmission of really sensitive information.
This remote site feeds back to a monitoring station at HQ a streaming feed from six security cameras and during office hours, a single computer requires access to cloud services for data transfers of quite large files. Also supported are four VoIP phones and an intruder alarm system. A remote POS service is also in the mix. Remote access is desired to maintain all devices instead of a round trip of 50 miles to visit the site.
Yes we currently use the basic STARLINK service, although out of preference, would love to have FTTP at 500/75, but that is unlikely to be an option available for many years to come, if ever. There is no mobile signal at this location. Current thoughts are to ditch two of the three PSTN lines.
Its just a necessary evil to pay £180 pm to give us what is needed. Alternative suggestions are welcome though.
