The 9603N is a drop in replacement for the 9603 which is mechanically and electrically equivalent. They are identical in form, fit, function and electrically equivalent. The Iridium 9603 transceiver combines the global coverage of the Iridium satellite constellation with the low latency of the Iridium Short Burst Data Service to provide highly reliable satellite communications from pole to pole. With the smallest form factor of any commercial satellite transceiver available today, the Iridium 9603N is ideal for space-constrained applications including monitoring, tracking and alarm systems.
