# EZR33T 4G-LTE Router

The LTE modem inside the outdoor 4G router connects to the mobile networks, and then the router provides internet connections on Wi-Fi and LAN Ethernet. It uses Nano-SIM cards in the dual SIM card slot. 

The outdoor enclosure was die-casted from ADC12 aluminum by 100-ton pressure with a white weather-proof coating. O-rings, seals, and gaskets protect the 4G router against water and dust. The durable enclosure provides waterproof protection in demanding environments and works in a temperature range of -40° \~ +80° Celsius.

The image below shows the basic working principle of the outdoor 4G router.

The outdoor 4G router has a standalone MIMO Wi-Fi hotspot with a DHCP server and supports a wireless Wi-Fi relay connection.  It has a powerful Wi-Fi booster inside with transmission speeds of up to 300Mbps. The Wi-Fi signal can cover 150-300 yards in the open space.

Complying with 802.3af/at PoE standard, the outdoor 4G router uses a LAN cable to transmit both DC power and Ethernet data. It supports a max 50-meter LAN cable. You can also power it up with a 12V DC power adapter. You can connect a network switch, second router, or computer to the LAN port on the PoE injector to extend the 4G internet to an indoor area.
