In the proposed SBIR Phase I program, SiCOM will: 1) demonstrate and parametrically field-characterize BitSURE(tm) an innovative and unprecedented interference and multipath tolerant spread-spectrum wireless high speed digital communications technology; and 2) develop a point modem design for a revolutionary reduction in size, power and cost for Phase II using SiCOM's(tm) unique Application Programmable Integrated circuit (APIC(tm)) design and fabrication resources. BitSURE(tm) modem technology creates a robust communication link under a wide rang of conditions, including high interference, distortion, and jamming. BitSURE's(tm) flexible spreading capability accommodates all link conditions and provides protection against unauthorized detection through lower spectral density and the intentional use of local interference. Thus, BitSURE(tm) is ideal for a variety of high-speed wireless communications applications where link pathologies make traditional communications impractical, or where such pathologies are part of a strategy to mask the communications link. BitSURE(tm) technology provides for error rate of 10(-10) or better, facilitating encryption and reliable transmission of critical data as well as high resolution live video. The proposed program, through Phase II, will dramatically extend design and functionality, and provide an entry into Phase III, where BitSURE(tm) modems will be developed as commercial and military products. Anticipated products resulting from a successful program will benefit a wide variety of military and commercial applications. Military applications include covert high-speed communications, tactical communications and DARPA's GLOMO program. Commercially, SiCOM will sell ICs for modems for unlicensed bands, where interference is rapidly becoming a serious problem, for uses such as: bypass of wired infrastructure, wireless T1 links to businesses, schools, internet service providers, etc., and campus building/LAN bridges.
