NASA requires communications support for users in remote sites that do not have permanent Internet access. Typically this is a mobile field simulation expedition that has a limited life span and can take place anywhere in the world. NREN's expertise in satellite engineering has led to providing the following innovative support solutions for hybrid (ground, wireless and satellite) deployments:

• Wireless network engineering

• Engineering topology and application tuning for optimal use of satellite resources

• IP Tunnels for provision of internal addressing to hosts in the field

• Coordination for use of domestic and foreign high performance research networks to transport field communications including video and Voice over IP traffic

• Security services
