Theory of operation
The 60 GHz cnWave devices support Facebook connectivity technology called Terragraph. cnWave
devices implement IEEE 802.11ay WLAN standard and use 60GHz frequency band for wider spectrum
and higher capacity. cnWave devices can provide multi-gigabit throughput from 100 M to 1.5 KM.
Deployment of the devices uses Open/R based layer3/IPv6 mesh for efficient distribution of traffic
between the nodes and higher availability of the traffic. This also overcomes non-line of sight issues.
Devices use TDMA/TDD technology to achieve density deployment efficiency. Network and the nodes
are configured, controlled, and monitored by a cloud-based E2E Controller.
Following terminologies are used for the network deployment:
l Distribution Node (DN) - DN connects with other DN for mesh network
l Client Node (CN) - CN connects to DN to provide high-speed connectivity
l PoP - DN connected to the back-haul
l CPE - Customer premises equipment devices like Wi-Fi router
