SOF tactical data networks using commercially available packet equipment

This paper presents an interim solution for the development of tactical data networks (TDN) for use by special operation forces (SOF) engaged in operations other than war (OOTW) and similar missions. Missions typified by OOTW generally require messages of greater length than typically handled by SOF communication systems. Additionally, the frequency of these messages may be hourly or less. Often this information requirement can exceed the individual message handling capability of current team-level communications systems. A commercially available packet radio terminal node controller (TNC) was used as part of a digital communications wide area network during Operation Uphold Democracy in Haiti. The experience gained with this system and later research suggests that commercially available TNCs can be easily modified to create tactical packet networks. Such networks could provide an interim solution to the challenge of sending and receiving relatively large amounts of information in unattended operation. This paper describes these networks that would enable deployed teams to communicate more effectively and efficiently with other elements than by using traditional communication methods to contact them. These elements are those within and beyond the current operational area
