| Abstract(in English) | This paper clarifies 802.15.4k DSSS (direct sequence spread spectrum) systems are suitable for wide area 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 the one of 802.15.4g by DSSS (1023 spreading factor) and FEC of 802.15.4k DSSS systems. In addition, this paper clarifies the area where 802.15.4g cannot survive under 802.15.4k CCI and vice versa. The area of 802.15.4k systems cannot survive with 802.15.4g system interference is 1/50 of that of 802.15.4g systems. Furthermore, we have shown the directive base station antenna can reduce the interference receiving area to 1/5 of that of the systems employing omnidirectional base station antenna. |
