Additional Airsynergy User Manual Statements

Airsynergy basestation, FCC ID: O2J-255AS, operating on frequencies 2503-2569 MHz
(5 MHz channels) or 2506-2566 MHz (10 MHz channels)
Federal Communications Rules for operation in USA
The correct setting of the following Base Station parameters in Netspan, are critical to
the correct operation of equipment in compliance with the rules detailed in 47CFR27:
• Transmit Power
• Transmit Frequency
• Channel Bandwidth
Any attempt to alter these parameters outside those permitted by the Netspan software or the
operator license could be a violation of that license

Transmit Power / Tune-up
Transmit power is set using the Netspan management software during install /commissioning.
The unit may be set to transmit with a power of up to 30 dBm at each antenna port when
connected to cross polarised antenna with maximum gain of 18dBi.

FCC and Industry Canada RF Exposure Requirements
FCC Maximum Permissible Exposure (MPE) limits for equipment operating in the
frequency range 1500 – 100,000 MHz is 1.0 mW/cm2.
Following installation and commissioning, the safe distance from the antenna is the
greater of:
20cm
Or
r cm, where r = √ (PG/4πS)
P: power input to antenna(s) in mW
G: numeric gain of antenna relative to isotropic radiator
S: power density in mW/cm2 = 1 mW/cm2
The device has two antenna ports, so safe distance from the antenna shall be the greater
of:
20 cm or √ (2*PG/4πS)
Which gives
20 cm or √ (0.16*P*G) cm.
