1.1.4 Antennas
In the system architecture, the antenna is approached as an independent element. This provides the
operator with the flexibility to select the antennas source according to its supplier policy. To ensure the
availability of antennas that complement the solution, Telrad works closely with several antenna
suppliers to ensure availability of antennas that comply with its requirements.
In cases where the operator prefers other antenna vendors, Telrad can provide a recommended antenna
specification based on the required antennas types.
Antennas may support mechanical down-tilt (MDT) using a suitable mounting kit, or electrical down-tilt
(EDT) that may be either fixed or adjustable using a special adjustment screw.
In addition to a range of standard commercial antennas, Telrad offers also a special attached antenna
designed for convenient installation on top of the BreezeCOMPACT unit. For the BreezeCOMPACT unit,
a special mounting kit allows installation of a standard antenna on top of the unit to minimize the space
required for installation.
For details on antennas offered by Telrad refer to “Antennas” on page 15.
1.1.5 GPS
GPS is used to synchronize the air link frames of Intra-site and Inter-site located Base Transceiver Stations
to ensure that in all Base Stations the air frame will start at the same time, and that all Base Stations will
switch from transmit (downlink) to receive (uplink) at the same time. This synchronization is necessary to
prevent Intra-site and Inter-site interference and Base Stations saturation (assuming that all Base Stations
are operating with the same frame size and with the same DL/UL ratio).The all-outdoor GPS Receiver is a
pole mountable GPS receiver and antenna in a single environmentally protected enclosure that is
powered from the unit.
Starting from R5.0 GPS Chaning is supported, where the chaining enables using a single GPS
receiver for several collocated units, below diagram which explain the GPS chaining connectivity:
