4 BreezeCELL Network Elements
The BreezeCELL network is composed of three parts: BreezeCELL Head end equipment, Coaxial
Network equipment and Customer Premises (or end user) Equipment.
4.1 BreezeCELL Head End Equipment
The BreezeCELL head end equipment is co-located with the TV signal source of the building. The
purpose of BreezeCELL’s Head end equipment is aggregating wireless services signals, converting them
into the correct frequency range and combining them on the coaxial network. Remote monitoring and
control of the Remotes is performed using the monitoring system in the headend. The wireless
equipment (microcell or repeater) is also installed at the same location.
4.1.1 UDC – Up Down Converter
The wireless native RF signal is inserted into Alvarion Up/Down Converter (UDC). The UDC converts the
original wireless signal into the 960 – 1155 range. In TDD networks (WiMAX) the UDC also converts
TDD signals to FDD. The output of several UDCs can be aggregated together by the CCD (see
4.1.2
below) in order to combine several operators and technologies or aggregate traffic.
