Huawei B618 is a new LTE Wi-Fi Cube that supports LTE of category 11 with up to 600 MBit / s in the downlink and 50 MBit / s in the uplink. It is visually very closely resembling the design of the Huawei E5180 and can therefore be designated as its successor. The device is square and quite "high" built, on the front there are various LEDs as well as a WPS button. On the back there is a power button, two RJ-45 Gigabit LAN connectors (one of which can also function as a WAN connector) and a USB 2.0 connector. There is also an RJ-11 connection for an analog telephone or fax machine as well as the connection for the external power supply. Under one cover are two connectors for an external antenna. There is no battery for mobile use.
