WipLL Radio Technology - Physical Layer System Description
2-18 Airspan Networks Inc. 25030311-08
2.5.2.5. External Antennas
For most bands, WipLL products allow connection of a large variety of external
antennas. However, WipLL 700 provides a limited variation of external antennas,
including, amongst others, the following:
 90° panel or omnidirectional (for BSR)
 14-element yagi antenna (for SPR)
These external antennas can be supplied by Airspan. The external antennas connect
to the WipLL devices by an N-type connector.
2.5.2.6. RF Planning Guidelines for Band C in FCC Market
Some operators (e.g., in the USA) have licenses for Band C (710 – 716 MHz and
740 – 746 MHz). When operating in Band C, WipLL 700 allows a maximum of four
BSRs at a Base Station (according to FCC regulations). This is to reduce RF
interference with other radio devices that may be operating in nearby frequencies.
With the 1 Msps mode, the center frequencies are 711.5, 712.5, 713.5, 714.5, 741.5,
742.5, 743.5, and 744.5. Thus, the frequency allocation for four BSRs (i.e., sectors)
is 711.5, 741.5, 714.5, and 744.5.
With the 1.33 Msps mode, the center frequencies are 712, 713, 714, 742, 743, and
744. Thus, the frequency allocation for four BSRs (i.e., sectors) is 712, 742, 714,
and 744.
