Power density exposure limit
Install the radios for the 60 GHz cnWave™Platform Family of wireless solutions so as to provide and maintain the minimum
separation distances from all persons.
The applicable FCC power density exposure limit for RF energy in the 57 – 66 GHz frequency bands is 10 W/m2. For more
information, see Human exposure to radio frequency energy
.
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 tables show calculated recommended separation distances, for the 60 GHz cnWave™ for Europe the USA and
Canada. These are conservative distances that include compliance margins.
At these and greater separation distances, the power density from the RF field is below generally accepted limits for
the general population.
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.
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.
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
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.
