Offshore Connectivity Has a New Baseline
For decades, maritime operations have faced one bottleneck: the further a vessel sails from shore, the weaker the connection becomes. Video surveillance stops streaming, remote diagnostics fail and crew welfare services drop offline. The 5G Maritime CPE from Shenzhen Antenajie Communication Technology Co., Ltd. closes that gap, delivering stable, high-speed 5G connectivity up to 120 km from the shoreline.
An All-in-One Offshore 5G Terminal
Built for the smart ocean economy, the terminal converts long-range 5G into WiFi 6 and wired broadband on board. Antenna, radio, routing and remote management share one weather-sealed housing, with no dish alignment and no separate outdoor unit, so it suits fishing fleets, patrol boats and offshore wind service vessels alike.
Engineered for Long-Range Performance at Sea
- Deep N28 700 MHz optimisation: the radio and omnidirectional high-gain antenna are tuned for the 700 MHz band, the most effective low-band spectrum over water. Offshore link: 80 km standard, up to 120 km (67.5 nm) on the long-range model.
- 4x4 MIMO and 26 dBm Class 2: higher-order MIMO and 26 dBm radiated power lift uplink and downlink throughput far beyond conventional marine routers, enough for live video and cloud applications.
- Dual-SIM redundancy: two standard SIM slots with automatic failover in under three seconds.
- GNSS tracking: BeiDou B1 and GPS L1 positioning to better than five metres, with configurable reporting and track playback.
- WiFi 6 and gigabit Ethernet: 802.11ax on 2.4 and 5 GHz for crew devices, plus an RJ45 port for switches, access points and IP cameras.
- Marine-grade build: IP66 sealing, -35 °C to +75 °C operation, IEC 60945 salt-mist compliance and MTBF above 70,000 hours.
- Open platform: Linux OpenWrt firmware with remote configuration and over-the-air upgrades.

Applications Across the Smart Ocean Economy
The terminal delivers a general-purpose IP link for every maritime segment needing data backhaul at sea:
- Patrol and law-enforcement vessels: real-time video surveillance and command-centre reporting.
- Aquaculture and fishing rafts: remote cameras and water-quality sensors monitored from shore.
- Offshore wind and construction platforms: turbine inspection video, condition monitoring and technician communications.
- Fishing fleets: crew internet, catch reporting and fleet management.
- Live streaming: crews broadcasting from open water with uplink capacity for HD video.
- Environmental monitoring: buoys, islands and sensor platforms uploading telemetry.
Deployment in Minutes, Maintenance from Shore
Installation is a sealed, pole-mounted routine: fix the bracket, slide the CPE onto the pole, connect DC 12-24 V power and a LAN cable, and the link is live. Three LEDs show status, and the modular plug-in design allows field replacement of the radio module without opening the housing. Fleet managers configure reporting and upgrade firmware remotely, so technicians no longer need to visit vessels in port.
Market Outlook: Maritime 5G Demand Is Accelerating
Three structural forces are pushing demand higher. Regulation: the 2022 amendments to the Maritime Labour Convention oblige shipowners to give crew reasonable internet access, making connectivity a compliance item. Digitalisation: e-navigation, remote surveys, predictive maintenance and unmanned vessel projects all need a continuous IP link at sea. Economics: offshore wind, aquaculture and marine monitoring are growing beyond terrestrial infrastructure, and submarine fibre to every site is not commercially viable.
Low-band 5G is the enabler. 700 MHz coverage reaches far beyond the coastal 4G footprint most marine routers depend on, and coastal sites keep densifying across Asia, Europe and the Middle East. That opens a market for terminals holding a 50-120 km offshore link at a fraction of satellite cost and latency, while owners shift budget from metered airtime to predictable 5G data plans.
