Select the specific port assigned to the "PC UI Interface."

When a modem becomes unresponsive or requires a fresh state after a configuration change, use these system commands:

A Huawei-proprietary command that delivers highly detailed readouts for specific network modes (LTE, WCDMA, GSM) including RSSI, RSRP, SINR, and RSRQ. Network Mode Selection (Band Locking)

The is designed for the modern smart home. It features 9 dBi high-gain antennas to ensure stable 5G connectivity even in weak signal areas. Equipped with Wi-Fi 6 supporting up to 128 devices, it includes both a standard 1 Gbps Ethernet port and a 2.5 Gbps Ethernet port for ultra-fast wired connections. A unique feature is its RJ11 telephone port , allowing legacy telephone line connections. The Huawei AI Life App enables intuitive management, parental controls, and signal optimization.

: Allow users to attach directional outdoor antennas to boost reception in weak signal zones. Software Integration: EMUI and LinkHome

Once inside the , you will primarily use AT commands (Attention Commands), an industry standard for modems. Here is your cheat sheet.

display interface cellular — Provides real-time statistics on the cellular connection, including signal strength (RSSI, RSRP), signal quality (RSRQ), and cell tower ID.

Several lightweight, free applications can send text-based instructions to serial ports:

: If you type commands but the letters do not appear on screen, your terminal's "Local Echo" feature is turned off. Type ATE1 and press Enter to force the modem to echo your keystrokes back to the screen.

Whether you are configuring a single IoT gateway or managing a fleet of remote 5G terminals, following these terminal management best practices will ensure reliability:

Always keep an active record of your original modem properties before altering terminal parameters to ensure you can easily revert to default states if necessary.

The is Huawei’s flagship 7nm multi-mode 5G modem chipset, featuring the world’s first 7nm process technology for 5G multi-mode modems. It supports both NSA (Non-Standalone) and SA (Standalone) 5G network architectures, is fully backward compatible with 2G/3G/4G, and incorporates carrier aggregation technology for peak download speeds up to 3.6 Gbps.

The E5573 supports up to 10 simultaneous Wi-Fi connections and includes a comprehensive web-based management interface for configuration. It also works with the Huawei HiLink app, which supports a wide range of Huawei mobile Wi-Fi models for easy management from your smartphone.
