Radiation hazard assessment
ETSI method
This section evaluates the radiation levels produced by the PTP 800 products
against the following standards:
x
1999/519/EC
public to electromagnetic fields (0 Hz to 300 GHz).
x
EN 50385:2002
base stations and fixed terminal stations for wireless telecommunication
systems with the basic restrictions or the reference levels related to human
exposure to radio frequency electromagnetic fields (110 MHz to 40 GHz) —
general public.
x
EN 50383:2002
electromagnetic field strength and SAR related to human exposure from radio
base stations and fixed terminal stations for wireless telecommunication
systems (110 MHz to 40 GHz).
Exposure categories
EN 50385:2002
electric, magnetic, and electromagnetic fields that are based directly on
established health effects. Between 10 GHz and 40 GHz, the physical quantity is

Antenna directivity
The Motorola recommended antennas have Hi-Performance polar patterns in
accordance with ETSI EN302 217-4-1 classes 2 and 3. They have gains in excess of
30 dB and beamwidths of less than 5 degrees. Thus, they provide high attenuation
of radiated energy at the sides and rear of the antenna.
