On spectrum occupancy evaluations from the standpoint of body area networks in ISM band

Abstract

Spectrum occupancy evaluations (SOEs) provide statistical insight regarding frequency resource utilization patterns for a given frequency band. In modern health-care systems, wireless solutions are trending and a number of wireless body area network (WBAN) applications are being developed. Industrial, scientific and medical (ISM) band is an unregulated, license free band where WBANs will co-exist with several other wireless technologies. This particular research work is focused upon SOEs from the standpoint of WBANs in 2.35-2.50 GHz band. A week long SOE campaign was undertaken at Oulu University Hospital emergency ward. SOE metrics evaluated include channel occupancies and spectrum resource occupancies.
