Product Description
This section provides information about the 60 GHz cnWave product from Cambium Networks. It also
describes its features, characteristics, and other related concepts.
Introduction
The 60 GHz cnWave products support a wide spectrum of up to 9 GHz (57-66 GHz) that is typically
divided into channels of 2 GHz each. The 60 GHz band is largely uncongested when compared to 2.5 GHz
and 5 GHz public bands, which are currently used for Wi-Fi. The 60 GHz band is an unlicensed millimeter-
wave band that can provide massive speeds and throughput with Line of Sight (LoS) applications.
The 60 GHz band is located in the millimeter-wave (30 GHz to 300 GHz) portion of the electromagnetic
spectrum.
The millimeter-wave portion of the RF spectrum has been largely unexploited for commercial wireless
applications. 60 GHz wireless products enable two-way wireless communications at data rates that was
previously achieved using fiber optic cables.
In addition to the high-data rates (accomplished in this spectrum), energy propagation in the 60 GHz
band has benefits such as excellent immunity to interference, high security, and frequency reuse.
Frequency bands
The 60 GHz band is divided into 11 channels, each with a bandwidth of 2.16 GHz starting from 57.24 to
70.2 GHz. Channels 1 to 6 support 2.16 GHz bandwidth and are defined in 802.11ad. Channels 9 to 13
support 4.32 GHz bandwidth and are added to 802.11ay.
