FNB310 Description
Core Purpose
The FNB310 is a 5G indoor CPE designed to convert cellular data into wired and Wi-Fi internet access. It allows users to deploy broadband quickly without relying on fixed-line infrastructure. This makes it suitable for locations where fiber or DSL is unavailable or difficult to install. It supports both 5G SA and NSA modes, as well as LTE fallback, ensuring flexible deployment across different network environments.
Connectivity and Communication
The device connects to 5G Sub-6 networks with theoretical speeds up to 2.5 Gbps downlink and 600 Mbps uplink. When 5G is not available, it supports LTE with up to 1 Gbps downlink. This ensures stable connectivity across varying coverage conditions. It includes 2 × 1G Ethernet ports (LAN) and 1 × 1G LAN/WAN port, allowing connection to computers, switches, or other network equipment. This makes it easy to integrate into both home and small commercial networks. Dual-band Wi-Fi 6 (2.4GHz + 5GHz) provides local wireless access for multiple users and devices. With 2×2 MIMO support, it delivers reliable indoor wireless coverage for typical office or home usage. A Nano-SIM interface, compatible with eSIM, enables flexible carrier deployment.
Wireless Performance
The 2.4GHz band supports up to 0.573 Gbps, while the 5GHz band supports up to 1.2 Gbps under 802.11ax. This helps maintain smooth data flow for streaming, office applications, and general internet access. Support for 20MHz, 40MHz, and 80MHz channel bandwidth allows adaptation to different wireless environments.
Power and Operating Environment
The unit operates on DC 12V/3A with a wide input range of 9–24V. This allows deployment in standard indoor environments with flexible power setups. Working current is under 1.1A at 12V, supporting stable daily operation. It operates in temperatures from –20°C to +60°C and supports up to 95% non-condensing humidity, making it suitable for a wide range of indoor conditions.
Expansion and Interfaces
The device includes:
- 2 × 1G Ethernet (LAN)
- 1 × 1G Ethernet (LAN/WAN)
- 1 × RJ11 telephone port (optional)
- USB Type-C 2.0
- Reset button for factory configuration
It supports 4 × 5G antennas (SMA-J) and 2 × Wi-Fi antennas (RP-SMA-J), enabling optimized signal reception. Optional accessories include sucker antenna, stick antenna, and all-in-one antenna configurations.
