Chapter 2: Product Description
Purpose
Cambium Networks’ 60 GHz cnWave solution provides easy, fast and cost-effective wireless gigabit connectivity for edge access
and/or high-capacity backhaul for edge access solutions at a significantly lower TCO than fiber infrastructure. Service providers
and enterprises now have access to Gigabit for business and residential connectivity, backhaul for Wi-Fi access or LTE/5G small
cell. Certified for Facebook Terragraph, cnWave mesh solutions are highly efficient at handling high-density deployments in cities
and suburban areas.
Introduction to 60 GHz
The 60 GHz band boasts a wide spectrum of up to 12 GHz that is typically divided into channels of roughly 2 GHz each. It is largely
uncongested compared to the 2.5 GHz and 5 GHz public bands currently used for Wi-Fi. The 60 GHz band is a millimeter wave
band that can provide massive speeds and throughput with Line of Sight (LOS) applications.
Understanding of 60 GHz
The V band is located in the millimeter-wave portion of the electromagnetic spectrum, where the wavelength varies from 10 mm
(30 GHz) down to 1 mm (300 GHz).
The millimeter- wave portion of the RF spectrum has been largely unexploited for commercial wireless applications. In addition
to the high-data rates that can be accomplished in this spectrum, energy propagation in the 60 GHz band has unique characteristics
that make possible many other benefits such as excellent immunity to interference, high security, and frequency re-use.
Frequency bands
60 GHz is divided into 11 channels each with bandwidth of 2.16 GHz starting from 57.24 to 70.2 GHz . Channel 1 to 6 has
2.16 GHz bandwidth and are defined in 802.11ad, channel 9 to 13 has 4.32 GHz bandwidth and are added in 802.11ay.
Channel 9 to 13 uses Channel Bonding feature to combine adjacent channel to create wider channel bandwidth

The following table describes the channels and corresponding bandwidths:
Channel Bandwidth (GHz) Center (GHz) Min. (GHz) Max. (GHz)
1 2.16 58.32 57.24 59.40
2 2.16 60.48 59.40 61.56
3 2.16 62.64 61.56 63.72
