A method of transmitting and receiving a plurality of Link 16 messages on a single subnet in a single timeslot includes a transmitting terminal packaging the Link 16 messages into an envelope enhanced throughput message (envelope LET message) and transmitting the envelope LET message to a receiving terminal, followed by the receiving terminal unpacking the Link 16 messages from the envelope LET message, restoring them to their original form, and presenting them to a host. Modification of the host is not required. The Link 16 messages can be relayed messages, and the transmitting terminal can be a relay terminal. The Link 16 messages can be concatenated within the envelope LET message, or another lossless packaging algorithm such as lossless compression can be applied. The terminals can be JTRS terminals, the Link 16 messages can be 115 kbps messages, and the envelope LET message can be a 2 Mbps LET message.
