Characteristics
Following are the important characteristics of 60 GHz cnWave products:
l
High throughput capability
CnWave products support 802.11ad Modulation and Coding Schemes (MCS) in a single channel (CB1) as well
as 802.11ay Enhanced Directional Multi-Gigabit (EDMG) modes in dual Channel Bonding (CB2). This enables
you to achieve Multi-Gigabit wireless rates. Refer to Table 3 and Table 4 for the supported CB1 and CB2 modes
along with the expected throughput values.
l
Unlicensed and interference free
Typically, the V band is either an unlicensed or lightly licensed band, which is relatively a new band. This band
has limited interference when compared to 2.4 and 5 GHz bands.
l
Line of Sight (LoS)
60 GHz is affected by oxygen absorption, it varies throughout the band. The absorption gets reduced if the
frequency gets increased. For example, the absorption is 15 dB/km in 60 GHz frequency, 5 dB/km in 64 GHz,
and 0.5 dB/km in 68 GHz. If the total channel is divided into 6 channels, then the mid-channel that is channels 2
and 3 has more absorption loss. From channel 4, the absorption level starts to drop. So only Line of Sight links
are available and Near LoS or non LoS links do not work with 60 GHz.

l
Rain fade
You can view significant rain fade for 60 GHz links, particularly those pushing the longer distances. Attenuation
depends on the rain rate which must be factored in while planning the network. Rain attenuation depends on the
level of the rain. The following table describes the rain level and absorption loss.
Table 2: Rain and attenuation
Rain Attenuation
Drizzle (0.25 mm/hr) 0.2 dB/km
Light Rain (2.5 mm/hr) 1.8 dB/km
Medium Rain (12.5 mm/hr) 5.6 dB/km
