N2 - Performance of safety applications of vehicular networks largely depends on the reliability of the communication channel. However the IEEE 802.11p channel is unreliable according to the previous measurement-based work, which reported that the whole communication range is a 'gray-zone' and the packet inter-reception time suffered from blackouts with a relatively high probability. Besides the 5.9 GHz band of the IEEE 802.11p channel, the vehicular networks have also utilized the Sub-1GHz band. Here, we have compared the beaconing performance of the Sub-1GHz channel and the IEEE 802.11p channel simultaneously in field experiments. The comparison is based on the packet delivery ratio (PDR) and the packet inter-reception (PIR) time. Results suggest that the Sub-1GHz channel achieves larger communication range with smaller jitter than that of the IEEE 802.11p channel. Different from previous work, the good-reception (PDR > 90%) zone exists in a considerable range of two channels in our field experiment environments. Moreover, the gain of the antenna can directly impact the good-reception zone.
