Satellite Internet Broadband Equipment

Application Overview

The IPSTAR broadband satellite system provides high-speed internet access across the country by installing IPSTAR satellite communication end stations at the user side. This effectively bypasses the limitations of ground network infrastructure, ensuring high-speed broadband access for users in a wide range of areas. IPSTAR communication satellites offer bandwidth resources according to demand, ensuring full utilization of bandwidth while creating new solutions for individual users, small and medium-sized enterprises, public internet users (such as hotspots), and Multi-Dwelling Units (MDUs).

Terminal Station Components Description

Currently, the IPSTAR system offers a variety of satellite end station configurations to meet different customer and application needs. Each IPSTAR satellite end station includes:

• High-performance, low-cost satellite modem
• Outdoor Unit (ODU)

IPSTAR satellite end stations are based on the most advanced broadband satellite platform, combined with IPSTAR gateway stations and efficient wireless interfaces, providing comprehensive broadband satellite access solutions.

Outdoor Unit (ODU) Description

All IPSTAR satellite modems work in conjunction with the outdoor unit. The outdoor unit has been specially designed and optimized to meet IPSTAR system specifications. Each outdoor unit includes:

• Antenna (available in diameters of 0.84m, 1.2m, and 1.8m)
• Upconverter (1-2W)
• Low Noise Block Downconverter (LNB)
• Feed

These components ensure efficient transmission of data, providing reliable broadband connectivity.

IPSTAR Outdoor Unit (ODU) Components

Similar to traditional VSAT end stations, IPSTAR's ODU uses L-band frequencies for signal transmission and reception. The ODU components include:

• Ku-band bi-directional antenna (diameter from 0.84m to 1.8m)
• Ku-band feed
• Upconverter (BUC)
• Low Noise Block Downconverter (LNB)
• Orthogonal Mode Transceiver (OMT)

The collaboration of these components ensures stable and efficient data transmission.

IPSTAR Satellite End Station Description

The IPSTAR satellite end station is a specialized standalone unit with the following features:

• One end connects to TOLL/STAR satellites for satellite communication
• The other end connects to a PC via Ethernet or USB port for data transmission

This end station is designed to meet the needs of efficient and stable satellite broadband access and is widely used in various fields, including remote areas and enterprise branch offices.
