Built with Qualcomm SDX75 and MT7981BA + MT7976CN + MT7531AE chipsets, ensuring full compliance with 3GPP Release 17 standards. Supports download speeds up to 6.12Gbps and uploads up to 0.9Gbps.
Features Wi-Fi 6 technology, delivering wireless throughput of up to 2402Mbps across both 2.4GHz and 5.8GHz bands.
Provides one Gigabit WAN interface and two Gigabit LAN interfaces for stable, high-performance wired connections.
Integrates 9 internal antennas—4 dedicated to LTE/NR and 5 for Wi-Fi—with intelligent antenna management for optimized coverage.
BandLock function allows the device to remain fixed on a chosen frequency band, improving stability in low-signal environments.
CellLock prevents the router from switching between towers, ensuring a consistent and reliable link.
AT command support enables advanced users to configure detailed network parameters.
IMEI modification capability allows flexibility in network registration and compatibility.
IP Passthrough mode assigns the public IP address directly to a LAN device, bypassing NAT.
VPN functionality establishes secure tunnels for remote access and site-to-site communication.
