Today's phones and tablets, monitoring medical sensors and networking equipment use popular wireless technologies such Wi-Fi, Bluetooth and ZigBee. Though each has a definite place for civilian/consumer applications, military and medical applications pose unique security and performances challenges that those technologies were not designed for and cannot entirely meet. Ultra-Wideband (UWB), a wireless technology originating in Army research and subsequently commercially developed and proven in consumer electronics markets, possesses advantages in security (encryption, LPI/LPD, and jamming) and performance (data rates, user density, and simultaneous connections) that are not shared by those civilian/consumer wireless technologies. Starix proposes to develop a secure UWB developer toolkit composed of a modular software development kit (SDK) supporting multiple OS (Android, IOS, Windows) and hardware UWB modem suite for easy embedded or add-on integration in a wide range of device type (sensor, phones, medical equipment, network adapters, etc.). The UWB toolkit will implement the necessary features to support medical applications (TCCC store and forward, vitals monitoring, telemonitoring, autonomous operations, and command & control) running on the Enroute Combat Casualty Care local secure network. The UWB toolkit will facilitate the use of UWB by vendors who want to securely integrate their product in this network.
