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. Concurrent users: 32. Easy connection via WPS button. The system supports simple, automatic registration via WPS (Wi-Fi Protected Setup). For setup, a single button press is sufficient: WPS-enabled network devices will then connect to each other 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, data traffic can easily be intercepted by third parties. Not all accesses can be encrypted directly, and even if you use an encrypted connection for certain operations, the information about where you are connected remains visible. A VPN tunnel addresses both issues, as it allows for the encryption of all network packets. Anyone who might be intercepting the public access traffic can only recognize a connection to the VPN gateway - the actual destination remains hidden. Multi-User MIMO/MU-MIMO. As part of the Wave 2 advancement 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. This means faster downloads and lag-free streaming for your devices.
