9522B L-Band Transceiver Product Information Guide
1.0 Product Overview
The 9522B L-Band Transceiver (LBT) is designed to be integrated into a specific application with other
hardware and software to produce a solution designed for a specific application or vertical market. Some
examples of these solutions include a maritime voice telephony terminal or a vehicle tracking solution.
The LBT functionally supports all of Iridium’s voice and data services. Applications can be built to use one
or multiple services using the voice and data interfaces. The 9522B is a functional replacement to the
9522A LBT, although the mechanical design and the electrical connectors differ. Connection adaptors are
available to enable the 9522B to be used in place of the 9522A.
A pass thru connector is provided to allow a GPS receiver to share the same antenna as the 9522B LBT.
The 9522B is regulatory approved for FCC, Canada, and CE assuming an antenna with a gain of ~3dBi.
This allows the LBT to be integrated into a variety of subscriber products, or retrofitted into existing LBT-
based products. These products, when integrated together will require regulatory testing to be conducted
by the integrator.
The LBT is essentially provided as a ‘black box’ with all interfaces provided via a 26-way 0.1” pitch
connector. The product provides the core transceiver module and SIM card reader. All other functions and
hardware such as keypad, display, power supply, antenna etc. must be provided by the solution developer.
The connector provides the following interfaces and connections:
• Analog Audio
• Control / Digital Audio
• RS232
• Power Input
• On / Off
