The R311 Pro of OEM is a mobile router, a device that connects other devices (e.g. computer, mobile, television) wirelessly, and shares internet access. It receives internet access through the integrated modem and uses the mobile network by installing a SIM card. The SIM card needs to have an active data connection.

It connects to the 4G network, which offers significantly higher speeds than 3G. To operate at this speed, the device needs to have corresponding coverage from the mobile network in the area we are in.
It is Wi-Fi 4 generation, an older generation recommended for use with few devices and for applications that do not require high speeds. It emits a signal at two frequencies, 2.4 & 5GHz. It offers higher speeds compared to single band and can connect more devices. The 2.4Ghz frequency is the most widespread and has a long range. The 5Ghz provides higher speeds than 2.4Ghz but is more sensitive to obstacles (e.g. walls) that reduce its range. This difference, as well as its more limited use, helps to have fewer interferences from other networks.

The device has the ability to configure a VPN (Virtual Private Network) so that traffic from all devices on our network passes through it. The VPN acts as an intermediary between us and the rest of the internet, giving us the ability to appear geographically in another country and the pages we visit see the VPN address as the visitor's address instead of our own. This provides us with anonymity and access to content with geographic restrictions. VPN services are usually paid with a subscription.

With MAC address filtering, it allows specific devices to connect based on their unique MAC address, excluding any device with a MAC address that has not been defined as acceptable.
