OneWeb Satellite System: Connecting the World from Space

OneWeb Satellite System: Connecting the World from Space

OneWeb is a prominent satellite internet company utilizing Low Earth Orbit (LEO) satellites to provide high-speed broadband access across the globe, especially to underserved and remote regions. This innovative company is revolutionizing satellite connectivity by offering a fast, reliable internet connection to locations that have traditionally struggled with access to reliable internet services.

Is OneWeb a LEO or GEO Satellite System?

OneWeb operates a Low Earth Orbit (LEO) satellite constellation. Unlike traditional Geostationary Earth Orbit (GEO) satellites, which are positioned about 36,000 kilometers above Earth, OneWeb’s satellites are much closer to the planet, operating at altitudes between 1,200 km to 1,500 km. This proximity significantly reduces latency, providing a more seamless and responsive internet experience. OneWeb’s LEO constellation is designed to address the increasing demand for internet services in remote, rural, and maritime locations.

OneWeb's Partnership with Telenor

OneWeb has formed a significant partnership with Telenor, a major telecommunications company. Telenor, known for providing mobile and broadband services in several countries, is actively involved in OneWeb’s mission to bridge the global digital divide. The partnership allows Telenor to leverage OneWeb's LEO satellite network to provide high-speed, low-latency internet services in regions where traditional ground-based networks are difficult to deploy. This collaboration is critical for bringing affordable and reliable connectivity to rural and remote areas in regions such as Asia, Africa, and Europe.

Services Provided by OneWeb

OneWeb’s satellite services are primarily aimed at connecting remote and underserved areas. Their service offerings include:

• High-speed broadband internet: Providing internet access to areas with limited or no connectivity.

• Mobile backhaul: Enabling mobile network operators to offer service in remote locations by backhauling data through OneWeb’s satellites.

• Enterprise and government services: Offering customized solutions for businesses, government agencies, and NGOs operating in hard-to-reach areas.

• Maritime connectivity: OneWeb’s satellites also provide connectivity to vessels at sea, offering high-speed internet for both operational needs and passenger services.

OneWeb’s services cater to a wide range of customers, including telecommunications providers, remote communities, maritime operators, enterprises, and governments.

How OneWeb's System Works

Diagram shows how OneWeb system  works 

The system works by using a constellation of LEO satellites in low Earth orbit to relay signals to ground stations. These satellites communicate with user terminals installed at customer locations, such as homes, businesses, or on ships. The customer’s terminal sends data to the satellite, which in turn transmits it to a ground station connected to the internet. This data flow enables customers to access fast and reliable internet, no matter how remote their location.

The LEO satellites are equipped with high-throughput payloads and advanced onboard processing to ensure efficient data transmission. With hundreds of satellites in orbit, OneWeb’s system offers global coverage, with the satellites seamlessly handing off connectivity between one another as they orbit the Earth.

Coverage Area

OneWeb aims to provide global coverage, focusing initially on underserved regions. While the system is still in development, it will eventually cover the entire globe, including remote and rural areas where traditional terrestrial broadband infrastructure is not feasible. Currently, OneWeb is focusing on providing coverage across the Arctic region, Africa, and parts of Asia, where internet access has been limited or non-existent.

OneWeb's LEO satellite network will provide internet access even in the most challenging environments, including rural villages, ships at sea, and airplanes in flight.

Pricing of OneWeb’s Services

While OneWeb has not publicly disclosed specific pricing details for its consumer services, the pricing model is expected to be competitive with traditional satellite internet services, offering affordable broadband to remote locations. The company aims to provide service at a price point lower than traditional GEO satellite systems, due to the reduced latency and improved bandwidth capabilities of the LEO network. Additionally, by working with partners like Telenor, OneWeb can integrate their services into existing mobile network plans, offering internet as an additional service for rural customers.

Prices will likely vary based on the type of service (individual, enterprise, maritime, etc.) and the location, with more specific pricing available as the network becomes fully operational and commercial services are rolled out.

Conclusion

OneWeb’s LEO satellite system is a game-changer in the world of satellite internet. By partnering with Telenor and leveraging cutting-edge LEO technology, OneWeb aims to provide high-speed internet to areas where connectivity has been previously unattainable. With its global coverage, OneWeb is working to bring the world closer together, improving access to education, healthcare, business opportunities, and more. As the company continues to expand, we can expect to see a significant shift in the way people access the internet worldwide.

OneWeb vs. Starlink Customer Antenna Specifications

Below is a comparison of the customer antenna specifications for OneWeb and Starlink, two leading satellite internet providers using LEO satellite constellations:

---

OneWeb Customer Antenna

• Size: Approximately 50 cm x 50 cm (for home and business setups)

• Weight: Around 2.5 kg (varies based on the configuration)

• Frequency Band: Ku-band (10-12 GHz for downlink, 13-15 GHz for uplink)

• Beamforming Technology: Utilizes electronically steerable beams for communication with LEO satellites

• Power Consumption: Around 15-20W (varies depending on the use)

• Mounting: Tripod-based or wall-mounted for easy installation in remote or rural locations

• Connectivity: The antenna connects to a modem/router at the customer's premises to provide internet access

• Service Area: Primarily focused on underserved regions, including rural, remote, and maritime areas

• Design: Compact, designed to be placed outside, often mounted on a pole or tripod
