Research Topics


An artful technical approach for achieving reliable >32 Mbps wireless transfer of integrated data, voice and video information is proposed. The technical approach utilizes 48 octet fast pack transport similar to as in ATM. The proposed wireless system provides network connectivity using legacy network interface standards (i.e. Ethernet, T1/E1, etc.) as well as through emerging network interface standards (i.e. ATM, SDH, etc.). To achieve high data rates, an artful solution to multipath propagation and its associated intersymbol interference is proposed. Novel waveform shaping techniques are utilized to gain spectral efficiency and highly linear modulators are used to prevent spectral blooming. Artful technical approaches are proposed to increase battery life (for a given throughput) by one or two orders of magnitude compared to presently available cellular telephones or 802.11 wireless LAN products. The use of a deterministic media access controller ensures low-latency (6 milliseconds) within the system and guarantees quality of service for the users of the system.
