Iridium Satellite throughput services are needed to ensure the continued operations of critical stations. The SSWSF

program is seeking a vendor to provide Iridium throughput services for the 204 actively transmitting radios, which will

require a base-plan of at least 12,000 bytes of data per month, and additional funding for sites that exceed the 12,000 byte

per month threshold, per terms of variable data usage fees. In addition, the SSWSF program has 38 Iridium radios in

inventory that should be placed in “standby” status and able to be activated within 2 business days of request. This

inventory is necessary for radio replacements, upgrades, and new site installations.
