The Iridium Satellite LLC 9603N is an IoT Module that supports two-way satellite communication connectivity. The Iridium 9603 delivers Iridium Short Burst Data in an extremely small form factor. Iridium Short Burst Data (SBD) - simple, efficient packet-based service for frequent short data transmissions between equipment and centralized host computer systems. Apple’s satellite design does not have a separate design, the signal is built inside the RF design and switches while using satellite signal. 9603N has a separate satellite design. The Huawei Mate 60 Pro satellite design uses a separate design, such as Iridium Satellite LLC. It differs in that the antenna is connected to an RF Switch which then sends a signal to Satellite Power Amplifier Module (1 signal) and RF Switch (2 signal) and then through the filters, the two signals enter the Satellite Transceiver. In the Iridium, the antenna is connected directly to the Satellite Power Amplifier Module and then one signal goes through the filter to the Satellite Transceiver and second signal goes without using a filter.
