Warning: To avoid RF interference between BSRs operating in the 700 MHz
where four BSRs are installed at a Base Station, a 1-meter separation must be
provided between the BSRs' antennas operating in the lower frequencies (i.e.
711.5 and 714.5 for 1 Msps mode; 712 and 714 for 1.33 Msps mode) and the
BSRs' antennas operating in the upper frequencies (i.e. 741.5 and 744.5 for 1
Msps mode; 742 and 744 for 1.33 Msps mode).
Warning: When using external antennas, the external antennas must not be
co-located or operating in conjunction with any other antenna or transmitter.
Warning: ASWipLL radios using an external antenna(s) must not be co-
located or operating in conjunction with any other antenna or transmitter.
Warning: Inherent risks exist in operating equipment in license-exempt bands
(i.e. 900 MHz). Airspan recommends that you do not purchase or deploy any
equipment that operates in license-exempt bands without first analyzing the
interference environment at each of your proposed deployment locations.
Please contact your Authorized Airspan System Integrator or Distributor if you
have any questions or require assistance regarding interference analysis.
Airspan Networks will not be held responsible for product performance issues
related to interference.
Warning: In environments that produce disturbances such as paging systems,
Airspan recommends using a narrow-band cavity filter and implementing the
appropriate frequency bands (within the filter's capabilities), i.e. building an
NVRAM frequency table using only these frequencies.
Warning: Mount outdoor radios so that their front panel ports face down to
prevent water from settling on the ports. This avoids damage to the units such
as corrosion and electrical short-circuiting.
Warning: Do not mount outdoor radios and external antennas in weathe
r
such as rain or lightening that may increase risk of electrocution.
