We are able to work remotely as long as we have a good internet connection. WiFi is nice when available but it is often slow and unreliable. What we depend on is a WiFi hotspot through our cell phones. Both of our phones are setup for hotspots so we can operate independently and we don't have to split the bandwidth.
In the fall of 2014, we installed a cellular booster. This greatly increased our ability to use our cell phones (better connections and higher throughput). At docks with a lot of metal roofs, there is still some interference but it really shines while anchored out.
Here are a couple of photos on a trip last year when I also have the speedtest results for LTE speed. The cellular booster is tied into the battery (12V system) so it can be active anytime.
We are happy anytime the down is 6+ and the up is at least 2 or 3. One of the dramatic differences was at St. Joe. Without the booster: 9/26/2018 10:33am 0.90 down / 1.02 up; with the booster: 9/26/2018 10:35am 45.3 down / 5.75 up.
