Huawei offers a new wireless LTE CPE B612 with powerful LTE modem recently. The B612 CPE supports LTE Advanced Cat6 with up to 300 MBit/s in the downlink and up to 50 MBit/s in the uplink, which is similar to the predecessor Huawei E5186 and B525 technically. A special feature compared to the predecessor model is the support for 4 × 4 MIMO antenna technology. The router also offers a telephone function and connections for external LTE antennas, which are common specs for the Huawei LTE routers.
