PROTOTYPE INSTRUMENTATION FOR GLUCOSE SENSOR

Not Available An intelligent access hub concept for wireless wide area networks is described. This intelligent access hub network is a high capacity multimedia, rapidly deployable architecture which nominally supports 10 Mb/s data rates from the ATM backbone to each fixed or roaming information kiosd. The concept exploits smart directive antennas which emphasize signal reception form the desired ik and de-emphasize interference from other directions in process called spatial filtering. Spatial filtering may be used to resolve the signal from distinct Iks providing for spatial division multiple access. The fundamentallomitation to SDMA is Signal to Interference ratio. A unique solution to mitigate the SIR is proposed using a smart beamformer and adaptation of radio bridge protocols. Transmission in directive beams with minimum power provides inherent Anti-Jam and low probability of intercept properties. The design is cots richto reduce cost, Weight, and risk of the system. The architecture is realized itn the unlicensed national information infrastructure band for low cost, unlicensed implementation, but the concept is applicable to other frequency bands. The architecture has immense commercial appeal as a cost effective alternative to paying wireline leases for provision of wide area networks.BENEFITS: Wireless wans crate a new class of service for commercial data service providers.
