This compact red alloy box has a neat row of ports along one end and two Wi-Fi antennae. It not only acts as a Wi-Fi router, it can also be used to repeat your yacht’s NMEA data via Wi-Fi.
The router accepts Internet connections from a dongle, Wi-Fi hotspot or satcomm system, while its LAN port allows for a direct PC connection. Two USB ports are for the Wi-Fi Bat booster antenna and a 3G/4G cellular dongle or NMEA input. Though compatible with 3G and 4G mobile cellular data via USB input, it doesn’t have its own SIM card slot or antenna.
Advanced features include least-cost routing, meaning it can calculate and automatically activate the cheapest method of connecting to the Internet at any time. It also has its own firewall and a built-in GPS tracker. Installation is just a question of powering up and logging on.
