The BGAN Physical Layer Tester (BPLT) supports the testing of physical layer performance and protocol implementation of Radio Access Nodes (RANs) and User Terminals (UTs) implementing Inmarsat's Broadband Global Area Network (BGAN), Fleet Broadband and Swift Broadband services.
The figure shows the configuration of the BPLT as it might be used for UT type approval. Other configurations are possible, depending upon the tests to be performed.
