Abstract:
This paper clarifies that 802.15.4k direct sequence spread spectrum (DSSS) systems are suitable for wide sensor networks with star topology. According to our evaluation, the robustness of 802.15.4k DSSS systems under the co-channel interference (CCI) is 60 dB stronger than that of 802.15.4g due to its DSSS (1023 spreading factor) and FEC. In addition, this paper clarifies the area where 802.15.4g cannot survive under 802.15.4k CCI and vice versa. The latter area is 50 times larger the former. Furthermore, we show that directive base station antennas can reduce the interference impacted area
