Empowering Global Maritime Connectivity: 80-120km Long-Range 4G/5G CPE Solution

The ATNJ 5G Cloud Box is a purpose-built Integrated Maritime 5G CPE Terminal that extends high-speed, stable 5G coverage from the coastline out to the high seas. Designed for fishing vessels, aquaculture platforms, patrol boats and offshore engineering facilities, the solution turns the “information island” of offshore operations into a fully connected smart ocean.

• Full-Band, All-Network 4G/5G Communication — Supports the full 5G TDD/FDD and 4G LTE bands, with 2 standard SIM card slots and dual-SIM backup to ensure high availability of the communication link.
• Deep Optimization for the N28 700M Band — Specially optimized for remote 5G communication in the N28 700M band, supporting 4×4 MIMO with a maximum equivalent transmit power of 26 dBm (Class 2) for longer communication distances and higher communication rates.
• Ultra-Long Maritime Communication Distance — The N28 700M band enables offshore internet access at distances of more than 80 km from land (depending on the specific environment).
• Dual-Mode GNSS Positioning — Supports BeiDou/GPS (B1/L1) dual-mode positioning with an accuracy better than 5 m, and supports position reporting and back-end trajectory tracking.
• Omnidirectional High-Gain Antenna — An omnidirectional high-gain antenna optimized for the N28 700M band enhances reception and improves uplink and downlink rates.
• Industrial-Grade Protection Design — Fully industrialized design with an IP65 protection rating, able to withstand harsh maritime environments (−35°C to +75°C).
• Integrated Plug-In Design — Integrated product design with a plug-in structure for easy later maintenance and module replacement.
• Simple Installation — Plug-and-play with quick commissioning and no professional training required. Supports ship-mounted pole installation.
• WiFi 6 Wireless Network — Converts the 5G network into a WiFi 6 network (IEEE 802.11ax), solving the problem of being unable to access the internet caused by terminal standards or poor signal reception.
• Wired Broadband Extension — Converts the 5G network into wired broadband, and supports external switches, wireless APs, cameras, laptops and other devices.
• Remote Network Management and Secondary Development — Supports remote network management configuration and upgrades, and supports the Linux OpenWrt system for user secondary development.
• Remote Device Supervision — Reporting parameters can be configured locally or remotely, and the back end monitors devices in real time for one-click viewing and efficient, convenient maintenance.
• Extra-Long Service Life — MTBF ≥ 70,000 hours, meeting the needs of long-cycle maritime operation.
