The 3650-3700 MHz frequency range is a licensed band in Canada 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
1
. This management software only
permits operation in the 3650-3700 MHz band.
Note: Netspan, the Airspan management system enforces FCC compliance in the upper
25MHz extension of this band above 3675 MHz
The unit 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
RSS-197 (Wireless Broadband Access Equipment Operating 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.
The Maximum permitted total power density allowed in RSS-197 is 1W/MHz
Certification testing was performed with an antenna gain of 11dBi and the following transmit
powers in Netspan software and these must not be exceeded during commissioning or use:
5 MHz channels:
23.5dBm
10 MHz Channels:
25.5 dBm
RF Exposure
The RF exposure requirements are detailed in RSS-210.
The safe distances from the AirSynergy Antenna unit is 25 cm under all operating
conditions.
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/cm
2
.
Following installation and commissioning, the safe distance from the antenna is the
greater of:

This software version is generically called the “
Airspan FCC-specific version
” as the software was
historically written to comply with 47CFR90Z which imposes a similar Contention Based Protocol
Requirement
