Additional User Manual Statements
Airsynergy Basestation, FCC ID: O2J-375AS, operating in the 3650-3700 MHz Band.
Federal Communications Rules for operation in USA
To ensure compliance FCC rules and regulations, the following should be observed:
•
The 3650-3700 MHz frequency range is a licensed band in the USA and operators
must have a valid spectrum license to operate Airsynergy equipment using this band.
•
The Airsynergy base station requires operation using an Airspan FCC-specific version
of Netspan supporting Listen Before Transmit. This management software only
permits operation in the 3650-3700 MHz band.
•
The unit and must be professionally installed.
•
Any attempt to alter these parameters outside those permitted by the Netspan software
or the operator license could be a violation of that license
•
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
47CFR90 subpart Z (Wireless Broadband Services in the 3650–3700 MHz Band):
o Transmit Power
o Transmit Frequency
o Channel Bandwidth
o Carrier Sense Threshold
o Carrier Sense Backoff Frames
Transmit Power
Transmit power is set using the Netspan management software during install /commissioning.
For 5MHz channel operation, the maximum permitted EIRP is 5 W. Due to the effective
occupied bandwidth and the additive effect of the MIMO antenna, the power setting in
Netspan must be set such that:
TX power (dBm) + 3dB1 + Antenna gain (dBi) ≤ 35.5 dBm
For 10 MHz channel operation, the maximum permitted EIRP is 10 W. Due to the effective
occupied bandwidth and the additive effect of the MIMO antenna, the power setting in
Netspan must be set such that:
TX power (dBm) + 3dB1 + Antenna gain (dBi) ≤ 39.0 dBm
Add 3dB for additive effect of two antennas

RF Exposure
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/4∏S)
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/4∏S)
Which gives
20 cm or √ (0.16*P*G) cm.
