The influence of vehicular traffic on cellular wireless system performance at microwave carrier frequencies

In this paper, mathematical analysis supported by computer simulation are used to study the impact of vehicular traffic on the performance of cellular wireless network operating at carrier frequencies greater than 2 GHz. The performance analysis is founded on the uplink information capacity of a cellular wireless system where co-channel interference are from multiple tiers. Results show that for both light and heavy vehicular traffic environment, at higher carrier frequencies and smaller cell size, other tiers of co-channel interfering cells become active. The results also that for heavy vehicular traffic the decrease in information capacity was lesser as compare to light vehicular traffic.
