Iridium Core 9523 L-Band Transceiver Module (LBT9523)
Description
OEM Integration for Custom Equipment
The Core 9523 mounts directly to a field application circuit board through a 40-way inter-board connector. This interface provides power, digital audio, serial control, SIM communication, data and fax signals, and general-purpose input and output connections. Its compact format allows Iridium connectivity to be incorporated into equipment without using a separate enclosed terminal.
Iridium Voice and Data Services
The module supports the primary Iridium narrowband communication services needed for integrated products, including:
- Satellite voice calling
- SMS messaging
- Circuit-switched data
- Short Burst Data
- Iridium Push-to-Talk capability
- Location-based services
Service availability depends on the host-product design, firmware, Iridium provisioning, and applicable service plan.
Short Burst Data Messaging
For tracking, telemetry, command, and remote-status applications, the 9523 supports two-way Iridium Short Burst Data messaging. It can transmit mobile-originated messages up to 1,960 bytes and receive mobile-terminated messages up to 1,890 bytes.
Host Power and Antenna Requirements
The host equipment must provide the module’s required battery and boost-voltage supplies. A certified Iridium-band antenna connects through the module’s miniature I-PEX RF interface and should have 50-ohm impedance, right-hand circular polarization, no more than 3 dBi gain, and a maximum operational VSWR of 1.5:1. Appropriate RF protection and system-level regulatory design are required.
Industrial and Mobile Applications
The Core 9523 can be integrated into equipment for maritime operations, aviation, rail systems, utilities, oil and gas sites, autonomous platforms, remote monitoring, and government applications. Its combination of voice and data services makes it suitable for designs that require more communication options than an SBD-only module provides.
