Cell Extender
Cell Extender
The Cell Extender operates as an Access and Subscriber Unit that are
connected back-to-back. The Subscriber Unit component operated in
the 2.4 GHz band and provides connectivity to the primary
BreezeACCESS II base station. The Access Unit component operates in
the 900 MHz band and serves the Subscriber Units located in the area
covered by the Cell Extender.
The CX-2.4-900 Cell Extender is comprised of an Interface Unit, a
2.4 GHz Radio Unit and a 900 MHz antenna.
The Interface Unit includes the interface (indoor) unit of a
BreezeACCESS II Subscriber Unit and a BreezeACCESS 900 Access
Unit. These two units are connected to each other via a hub module. It
provides an interface for an optional local Ethernet connection and is
powered from the mains (110/220VAC).
The SU-RA-2.4 radio unit of the Subscriber Unit component
incorporates the radio module and an integrated flat antenna.
The Interface Unit is connected to the 2.4 GHz Radio Unit via a 50ohm
coaxial Intermediate Frequency (IF) cable. This cable carries 440 MHz IF
signals between the Interface Unit and the Radio Unit. In addition, this
cable transfers power (12 VDC) and control signals from the Interface
Unit to the Radio Unit.
The AU-900 Access Unit connects to an external antenna.
Both BreezeACCESS equipment in both the 2.4 GHz and 900 MHz
bands operate in Time Division Duplex (TDD) mode. It employs wireless
packet data switching technology, using Frequency Hopping Spread
Spectrum (FHSS) radios.
