Overview Summary

Description

The Mercusys MB135-4G AC1200 Wireless Dual Band 4G LTE Router is designed to provide a practical internet connection wherever compatible 4G LTE coverage is available. Instead of requiring a fixed broadband connection, the router uses a Nano SIM card to connect to a mobile network and share the connection with multiple devices over Wi-Fi or Ethernet.

4G LTE Cat 4 technology provides download speeds up to 150 Mbps and upload speeds up to 50 Mbps. The router supports dual-band AC1200 Wi-Fi, providing wireless speeds up to 300 Mbps on the 2.4 GHz band and up to 867 Mbps on the 5 GHz band. This allows compatible devices to use the appropriate wireless band for everyday browsing, email, social media, streaming and other network activities.

The MB135-4G has four external antennas in total, including two detachable 4G LTE antennas and two external Wi-Fi antennas. The detachable LTE antennas provide flexibility where additional 4G signal coverage is required. The router can support up to 64 Wi-Fi devices, although the recommended client limit is 32 devices.

For wired networking, the router provides one 10/100 Mbps WAN/LAN port and three 10/100 Mbps LAN ports. The WAN/LAN port also allows the router to operate in Wi-Fi router mode when an Ethernet internet connection is available, providing an alternative connection method.

Network management features include guest networks, parental controls, data statistics, data limits, messaging, wireless scheduling, WPS, QoS, access control and firewall functions. The router can be managed through the MERCUSYS app or its web management interface.
