Hughes HL1120W LEO Terminal

The Hughes HL1120W LEO Terminal from Hughes Network Systems represents a major step forward in satellite connectivity. Built for the Eutelsat OneWeb network, this terminal combines electronically steered antenna (ESA) technology, high-speed throughput, and low-latency performance into a compact, field-ready solution.

Unlike traditional GEO satellite systems, the HL1120W is designed for modern connectivity demands, where latency, speed, and reliability directly impact operations. Whether for enterprise, government, or remote industrial use, this terminal enables fiber-like performance in locations where fiber simply does not exist.

At VSATplus, we supply the HL1120W with full technical consultation, integration support, and global delivery—ensuring you deploy a system that works in real-world conditions, not just on paper.

1. Product Overview

Satellite communications are undergoing a structural shift.

For years, GEO systems dominated the market. They offered global reach but came with limitations:

• High latency (~600 ms)
• Limited real-time application performance
• Bandwidth constraints

The introduction of LEO constellations like OneWeb changes that equation.

The HL1120W terminal is designed to leverage:

• Low Earth Orbit satellites
• Advanced flat-panel ESA technology
• Integrated modem and networking capabilities

This results in:

• Low latency (~70–100 ms range depending on network)
• High throughput connectivity
• Seamless user experience for modern applications

2. Core Features

2.1 Electronically Steered Antenna (ESA)

At the heart of the HL1120W is its flat-panel ESA.

Key advantages:

• No moving parts
• Instant beam steering
• Higher reliability compared to mechanical antennas

This allows the terminal to:

• Automatically track satellites
• Maintain stable connectivity
• Operate efficiently in dynamic environments

The antenna is also:

• Low-profile
• Aerodynamic
• Easy to install on rooftops or structures

2.2 Full-Duplex, Self-Aligning System

The HL1120W is a self-aligning terminal.

What this means:

• No manual pointing required
• Automatic satellite acquisition
• Continuous tracking without user intervention

It operates in full-duplex mode, enabling:

• Simultaneous upload and download
• Stable real-time communication

This is critical for:

• Video conferencing
• Cloud applications
• Enterprise networking

2.3 High-Speed Performance

The HL1120W delivers strong performance for a LEO terminal:

• Up to 195 Mbps downlink
• Up to 32 Mbps uplink 

This level of throughput supports:

• HD video streaming
• Enterprise applications
• Cloud-based workflows
• Remote office operations

2.4 Low Latency Connectivity

Because it operates on a LEO constellation:

• Satellites orbit closer to Earth
• Signal travel distance is reduced

Result:

• Much lower latency than GEO systems
• Real-time performance for critical applications

This enables:

• VoIP communication
• Video conferencing
• Financial and operational systems

2.5 Integrated Indoor Unit (IDU)

The HL1120W includes a powerful indoor unit:

• Wi-Fi 6 router (optional)
• 2 × Gigabit Ethernet ports
• MoCA adapter (Ethernet over coax) 

This eliminates the need for:

• Additional networking hardware
• Complex infrastructure

2.6 Optimized for OneWeb Network

The terminal is designed specifically for:

• Eutelsat OneWeb LEO network

Network features include:

• IP-based connectivity
• Differentiated QoS
• Multi-APN support 

This ensures:

• Flexible network configuration
• Service-level optimization

2.7 Rugged Outdoor Design

The HL1120W is built for real-world deployment:

• Operating temperature: -40°C to +55°C
• Weather-resistant enclosure
• Durable aluminum chassis 

This makes it suitable for:

• Harsh climates
• Industrial environments
• Remote installations

2.8 Plug-and-Play Deployment

One of the strongest operational advantages:

• Pre-configured system
• Minimal installation effort
• Self-pointing capability

This reduces:

• Deployment time
• Technical complexity
• Installation cost
