2.5. WipLL RF Antennas
WipLL provides a variety of internal antenna types as well as an option for
connecting off-the-shelf, third-party external antennas. Table 2-3 provides a general
description of the WipLL RF antenna parameters.
Table 2-3: WipLL RF antenna specification
Parameter Description
Antenna type
• Integral flat-printed antenna: for BSR, PPR, SPR, and IDR devices: No
RF cable is involved for connection between BSR and SPR. The interface
between outdoor radio unit-to-indoor unit (ODU-to-IDU) is by CAT-5
cable.
• Integral narrow-beam antenna: for the BSR device operating in the 3.5
GHz band.
• Integral high-gain antenna: for SPR and PPR devices operating in the
3.5 GHz and 2.4 GHz bands.
Polarization
Vertical (Horizontal polarization is optional for SPR at 3.5 GHz)
ETSI compliant
EN 302 085, Class CS1 for the BSR, and TS2 for the SPR
Receive diversity
Supported in single BSR through dual integral antennas
External third-
party antennas
(optional)
Connects to BSR, PPR, and SPR using an N-type connector. Connects to
IDR using a TNC connector. Provides further flexibility for the WipLL
operator to improve link budget or cost-effectiveness of the Base Station. For
example, an omni-directional antenna for 360º coverage can be implemented
by a single BSR.
For BSRs operating in the 700 MHz or 900 MHz bands, two N-type
connectors are provided for attaching two external third-party antennas for
dual antenna diversity at the WipLL Base Station. When operating in the 700
MHz band, the BSR is supplied with a panel-type antenna; the SPR model
with a yagi-type antenna
Notes: Devices with external antennas do not contain built-in (internal)
antennas.
