           | The way I understand marinetraffic works is by having AIS
           | receivers near shores and sending any received contacts to an
           | API. If this works the same way then there's probably a lot
           | fewer receivers so far.

       | container ship itself, but it was nearly impossible to get access
       | to reefer monitoring systems. We ended up just using 4G NB-IoT
