Early demonstration versions of the LW system used software written in the Ada programming language running on a Unix platform. In January 1999, in an attempt to reduce development costs and accelerate the program, the development work was transitioned to a multi-company team that had been organized by Exponent (NASDAQ: EXPO), an engineering firm with headquarters in Silicon Valley.
An intensive redesign of the system ensued, and both the embedded firmware and the application software were rewritten from scratch. Many of the COTS hardware components were purchased (literally "off the shelf") at Fry's Electronics, the Silicon Valley retail chain. Approximately 100 proof-of-concept Land Warrior units were built and successfully demonstrated in September 2000 by a US Army platoon that was air-dropped into a large war-fighting exercise at Fort Polk, Louisiana.
These initial prototype units, designated Land Warrior v0.6, were built around a PC/104 computer platform running Microsoft Windows. The system used the CAN-bus protocol on the wired PAN (personal area network). The communications subsystem was built using [B]Windows CE [/B]running on a StrongARM platform, and the wireless network protocol was IEEE 802.11. During the Fort Polk exercise, preliminary interoperability with traditional military radio networks was also demonstrated for LW v0.6, using a two-way, SINCGARS-compatible gateway radio.
