Meta introduced Terragraph to address the global demand for high-speed internet access. Traditional fibre-optic installations, while offering high performance, often involve significant costs and logistical challenges, especially in densely populated urban areas or regions with complex infrastructure.

Terragraph was designed to overcome these barriers by providing a wireless solution capable of delivering fibre-like speeds without the need for extensive physical infrastructure.

By utilising the 60 GHz spectrum, which offers wide frequency bands and is less congested, Terragraph enables efficient and rapid deployment of high-speed networks. ​

• High-Speed Performance: Terragraph delivers multi-gigabit speeds over the 60 GHz spectrum, providing users with fast and reliable internet connectivity. ​
• Mesh Network Architecture: Employing an open-source mesh design based on the Open/R protocol, Terragraph ensures high reliability and redundancy. This architecture allows for dynamic rerouting of data, maintaining network stability even if individual nodes fail. ​
• Cost-Effective Deployment: Deploying Terragraph is significantly more affordable than laying fibre-optic cables. The wireless nature of the technology reduces the need for extensive trenching and infrastructure, allowing networks to become operational in weeks rather than months or years. ​Cost analyses have also shown that Terragraph not only has significantly reduced deployment costs, but also lower total cost of ownership over the network lifetime compared to fibre.
• Advanced Technology: Terragraph incorporates features such as Time Division Duplex (TDD) and Time Division Multiple Access (TDMA) protocols, enhancing spectrum efficiency and network performance. ​

Terragraph’s versatility makes it suitable for various applications, particularly in scenarios where traditional fibre deployment is impractical:​

• Residential and Business Broadband: Terragraph can provide high-speed internet to residential homes, apartment buildings, and small to medium-sized businesses. This is especially beneficial in areas lacking existing fibre infrastructure, enabling rapid and cost-effective broadband deployment. ​
• Smart City Initiatives: Municipalities can leverage Terragraph to support public WiFi networks, smart street lighting, IoT applications, and intelligent traffic systems. The high capacity and low latency of Terragraph make it ideal for handling the data demands of smart city infrastructure. ​
• Event Connectivity: For temporary events such as festivals or conferences, Terragraph offers a quick-to-deploy solution to provide attendees with high-speed internet access without the need for permanent infrastructure.​
• Rural Broadband Expansion: In rural or underserved areas where laying fibre is economically or logistically challenging, Terragraph can bridge connectivity gaps, delivering high-speed internet to communities that would otherwise remain unconnected. ​
