HUAWEI 4G Router 2. WLAN Standard: IEEE 802.11b (Wi-Fi 2), IEEE 802.11g (Wi-Fi 3), IEEE 802.11n (Wi-Fi 4). Frequency band: 2.4 GHz, for up to 300 Mbit/s. Base connection: Mobile, WAN ports: 0, RJ-45 ports: 1, SFP ports: 0. 2x2 MIMO technology. Features: Firewall, VPN support, IP address filtering, Wi-Fi Protected Setup (WPS), APN management. Simultaneous users: 32. Easy connection via WPS button. The system supports simple, automatic registration via WPS (Wi-Fi Protected Setup). For setup, just press a button: WPS-enabled network devices will then connect automatically. Suitable Wi-Fi settings are adopted, and the product is ready for use immediately. Maximum discretion thanks to VPN support. The device supports the establishment of VPN connections and helps protect your privacy. When using a public access point for internet access, third parties can easily eavesdrop on your data traffic. Not every access can be encrypted directly, and even if you use an encrypted connection for certain processes, the information about where you are connected remains visible. A VPN tunnel solves both problems, as it allows for the encryption of all network packets. Anyone who might be eavesdropping on the public access traffic can only see a connection to the VPN gateway - the actual destination remains hidden. Multi-User MIMO/MU-MIMO. As part of the Wave 2 development of the 802.11ac standard, Multi-User MIMO technology has been introduced. By utilizing Multi-User MIMO, this device can stream data to multiple devices simultaneously. This allows your Wi-Fi network to deliver faster throughput to each connected client, resulting in quicker downloads and lag-free streaming for your devices.
