Huawei E5577-320 4G LTE Mobile WiFi Hotspot, Portable Router, Up to 16 Devices, 150 Mbps, Black

The HUAWEI E5577-320 is a portable Mobile WiFi hotspot designed for SOHO environments and business users who need shared Internet access through cellular networks. It supports LTE FDD, LTE TDD, DC-HSPA+, HSPA+, HSPA, HSUPA, HSDPA, and UMTS, allowing it to operate across several generations of mobile service. Supported LTE FDD bands are B1, B3, B7, B8, B20, and B28, while LTE TDD operation covers B38, B40, and B41. For 3G connectivity, the device supports Band 1 at 2100 MHz and Band 8 at 900 MHz. LTE FDD download speeds reach up to 150 Mbit/s and upload speeds up to 50 Mbit/s, supporting tasks such as web access, email, messaging, and file transfers.

The device creates a 2.4 GHz IEEE 802.11b/g/n wireless network and allows up to 16 WiFi users to connect at the same time. Built-in LTE/UMTS and WLAN antennas keep the unit self-contained, while 2×2 MIMO supports WLAN speeds of up to 300 Mbit/s under compatible 802.11n conditions. Internet access can also be provided to a computer through the Micro USB interface, so the hotspot can function as either a wireless modem or a USB modem. LTE/3G/WiFi auto offload enables the E5577-320 to use an available WiFi connection instead of mobile data. This is useful at home, in hotels, cafés, airports, and other locations with wireless access, where switching away from LTE or 3G can reduce mobile network traffic.

A 1.45-inch LCD and menu-style interface provide access to connection information and selected settings without requiring a separate screen. Using the menu and power buttons, users can browse device information, control automatic switching between LTE/3G and WiFi Internet access, and enable or disable WPS. Network status can show details such as signal level, operator name, and system mode. HUAWEI AI Life APP support provides a way to work with the hotspot, while the web interface allows APN profiles to be created, edited, or deleted. Users can also choose automatic or manual network selection and registration, turn LTE connectivity on or off, and manage PIN functions, including activation, locking, changing, and PUK-based unblocking.

Management functions include SSID broadcasting or hiding, Open, WEP, WPA2-PSK, and WPA/WPA2-PSK security options, WLAN MAC filtering, firewall controls, LAN IP filtering, Virtual Server, DMZ, UPnP, NAT, and configurable DHCP settings. SMS messages can be written, sent, received, and managed through the web page, with storage for up to 500 messages. A rechargeable 1500 mAh Li-ion battery provides up to six hours of operation and up to 350 hours of standby time, depending on the network. The unit measures 96.8 × 58 × 13.5 mm and weighs about 81 g including the battery. A standard SIM card interface and Micro USB port support setup and charging, while the dimensions make it convenient to carry or use while travelling.
