Calculation of power density
The following calculation is based on the ANSI IEEE C95.1-1991 method, as that provides a worst-case
analysis.
Peak power density in the far field of a radio frequency point source is calculated as follows:
Where:
S: power density in W/m
2
p: maximum average transmit power capability of the radio, in W
G: total Tx gain as a factor, converted from dB
d: distance from point source, in m
Rearranging terms to solve for distance yields:
Calculated distances and power compliance margins
The following table displays recommended calculated separation distances, for the 60 GHz cnWave™ for
Europe the USA and Canada. These are conservative distances that include compliance margins.
Note
Les tableaux suivants indiquent les distances de séparation recommandées calculées pour le
cnWave ™ 60 GHz pour l'Europe, les États-Unis et le Canada. Ce sont des distances prudentes
qui incluent des marges de conformité.
At these and greater separation distances, the power density from the RF field is below generally
accepted limits for the general population.
Note
À ces distances de séparation et à des distances supérieures, la densité de puissance du champ
RF est inférieure aux limites généralement acceptées pour la population générale.
60 GHz cnWave™ Platform Family ODU adheres to all applicable EIRP limits for transmit power when
operating in MIMO mode. Separation distances and compliance margins include compensation for the
antenna configuration of each product.
Note
L'ODU de la famille de plates-formes cnWave ™ 60 GHz respecte toutes les limites EIRP
applicables pour la puissance de transmission lors d'un fonctionnement en mode MIMO. Les
distances de séparation et les marges de conformité incluent la compensation de la
configuration d'antenne de chaque produit.
