Directional antenna and IP67 housing for outdoor use
A directional antenna concentrates reception in one direction, so the unit is fixed to an outside wall or a mast and aimed at the nearest cell tower. That is the point of it compared with a router sitting indoors. IP67 means the housing is dust-tight and survives temporary immersion in water, so rain and snow are not a concern. A single Ethernet cable runs into the building and carries both data and power.
