What is Terragraph and what does it mean to Cambium Networks?
Wireless Works by Cambium Networks hosted an engaging virtual discussion with David Botha from Facebook and Antony Holmes from Cambium Networks where we’re focusing on Terragraph MESH.

Terragraph is one of several projects a part of Facebook Connectivity. The mission of this organization is to get people online to a faster internet. Terragraph began looking at the problem of access to high-speed broadband which is limited by poor last-mile connections. Terragraph is a technology that operates on 60 GHz unlicensed band delivering fiber-like speeds. In markets where fiber access to consumers is cost-prohibitive and slow to deploy due to factors such as permitting, trenching, etc., Terragraph can be a better alternative to provide fiber-like connectivity at a significantly lower cost. It’s also much faster to deploy and can be brought to market in a matter of weeks.
Cambium offers lots of different wireless technologies and ways to get broadband to the masses. For 10 years, Cambium Networks had been trying to find a GHz solution. It wasn’t until Terragraph came along based on 60 GHz that it was a solution that was finally a solution that would take them to the markets. It provides a fiber-like performance in gigabit wireless connectivity. It’s resilient, expandable, and adaptable.

Terragraph’s distributive architecture

Terragraph’s distributive architecture – it’s about being able to get closer to your customer to utilize 60 GHz. You need the line of sight, turning non-line of sight into a line of sight. By distributing networks closer in the ground from the mast to the street corner. This technology works with its scalability, and you get the density. Terragraph is a great option for urban and rural communities.

Invested in RMD to come up with a solution to this problem and effectively and resulted in intellectual property and developments. FB isn’t an OME or service provider in this context all of this intellectual paragraph IP all that is Terragraph we part with it to commercialize. So it is licensed to Cambium Networks and other OME’s.
Terragraph solves the problem of rendering a service that you need to be highly reliable, resilient, and always available. This can be down with a server that is a high/high industrial grade high availability server that’s also expensive. But you can also find a way to solve this problem by investing in a fleet of several lower-cost servers. If you manage the fleet of lower-cost servers, you can render a high availability service. There are many positive attributes in solving the problem this way. Terragraph takes so many pages from this book and a reuses this concept efficiently.

60 GHz Telegraph solution vs other fixed wireless broadband

60 GHZ is a lot packed in a tiny amount of space. It’s not just about the access point it’s about the subscriber end too. It’s easier to install and more reliable, and with that installation is more reliable.
Beam Steering helps with the installation – EDMG (enhanced directional multi-gigabit) tiles that have multiple elements. You can change the phase of each element. Being able to change each element allows you to form a tight microbeam. That’s how you get the directionality. It does a scan to see where the client is and creates a beam to that specific client. This concept reduces interferences and concentrates power on that client.

Benefits to channel planning

One of the concerns with 60GHz is that it is unlicensed and interference between nodes. When you are forming links between pencil beams it’s a constrained radiation pattern. All the energy goes from node to node and doesn’t bleed out to neighboring nodes. It’s a powerful tool to mitigate self-interference and enables highly efficient use of the spectrum.
