The MC888 Ultra by ZTE is a mobile router, a device to which other devices (e.g., computer, mobile phone, television) connect wirelessly, and it distributes internet access to them. It receives internet access through the built-in modem and uses the mobile network by installing a SIM card. The SIM card must have an active connection with a data package.

It connects to the 5G network, which offers significantly higher speeds than 4G. For the device to operate at this speed, there must be corresponding coverage from the mobile network in the area where we are located.
It is of Wi‑Fi 6 generation, the most modern Wi-Fi standard that offers speeds up to 40% higher than Wi-Fi 5. It coordinates communication with connected devices to consume less battery and works better in environments with many Wi-Fi devices. Ideal for homes with many smart devices. It broadcasts a signal on two frequencies, 2.4 & 5GHz. It offers higher speeds compared to single band and connection of more devices. The 2.4GHz frequency is the most widespread and has a long range. The 5GHz provides higher speed than 2.4GHz but is more sensitive to obstacles (e.g., walls) that reduce its range. This difference and its more limited use help it have fewer interferences from other networks.
