6.2.1. Minimum Distance Between BSRs
To prevent radio interference, each BSR requires a minimum of 1-metre separation
between adjacent BSRs (see Figure 6-3).
1 Metre min.
Figure 6-3: Minimum separation between mounted BSRs
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 antennas of the BSRs 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 antennas of the BSRs 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: The BSR emits microwave radiation; a minimum distance o
f
200 mm must be maintained from the front of the BSR. However, for the 700
MHz band (i.e. WipLL 700), when external antennas are used, a minimum
distance of 800 mm must be maintained from the front of the device.
