Recently I came through outdoor LTE CPE used in rural connections.
Such a device is called MikroTik SXT LTE6 kit, and is an outdoor device for remote locations that are within cellular network coverage.
Due to its advanced LTE CAT6 chip design and high gain antenna, it can provide connectivity for your building even where cell phones fail.
It also has two Micro SIM slots for backup link.
It also support Carrier Aggregation…
Any idea on how efficient this is?
