Warning: For unlicensed bands, it is the responsibility of the person installing
the ASWipLL system to ensure that when using the outdoor antenna kits in the
United States (or where FCC rules apply), that only those antennas certified
with the product are used. The use of any antenna other than those certified
with the product is expressly forbidden in accordance with FCC rules CFR47
part 15.204. The installer should configure the output power level of antennas
according to country regulations and per antenna type.
Warning: For unlicensed bands, in accordance with FCC regulations, ensure
that the external antennas provide an EIRP of less than or equal to 36 dBm to
prevent interference with other radios operating in the unlicensed band. The
EIRP is defined by the following formula:
Max. Power Output + Antenna Gain - Cable Loss ≤ 36 dBm (EIRP)
Airspan does not supply cables for connecting external antennas. It is the
responsibility of the installer to provide the cable and ensure the cable
characteristics (i.e. cable loss) enables adherence to FCC's regulations
concerning maximum EIRP. When calculating output power based on cable
loss, always assume the ASWipLL radio is configured for maximum rate mode
(i.e. 1.33/4 Mbps), which provides greater Tx power than low rate modes.
The table below lists examples of cable loss per cable (not supplied by
Airspan) for maximum antenna gains, based on the formula above. Note that
the EIRP is either equal to or less than 36 dBm.
Warning: The ASWipLL radios emit microwave radiation. Therefore, a
minimum distance of 200 mm must be maintained from the front of the
ASWipLL radios, except when operating in the following frequency bands:
- 700 MHz (i.e. ASWipLL 700) = 800 mm
- 2.5 GHz (i.e. ASWipLL 2.5) = 500 mm
