A Robust, Mobile, Scalable Sensor Networking Communications System

On-Ramp Wireless has developing a highly innovative and disruptive new wireless networking technology called Ultra Link Processing (ULP) to address the necessary communications requirements of a wide area mobile networking system. To date, the performance of free spectrum physical layers (PHYs) (e.g., 802.15.4, 802.11x) and proprietary PHY extensions for such networking have not delivered acceptable solutions. This has resulted in fragmented implementations and significant system complexity and cost. A radically different physical layer and modem signal processing architecture is proposed to address flexible networking with superior performance in challenging radio environments and large geographic areas. In particular, the wireless requirements of the Autonomic Logistics program are well satisfied by this technology. Key features include: reliable communication in a urban environment of 2-3 miles in the 2.4 GHz frequency band, a 25-fold advantage in range over existing protocols; highly robust in high multi-path environments and highly jam-resistant; 25x capacity advantage over other protocols due to simultaneous link demodulation enabling thousands of nodes and efficient use of spectrum; and efficient new mesh networking protocol that can support 100s of network hops - link budget edge plus simultaneous signal demodulation, decreasing coordination requirements.
