This paper discusses the capability of the conventional double-tier and a unified micro-cellular network in supporting smooth handover for fast-moving terminals (FMTs). In the unified micro-cellular network, high speed packet transfer even to fast terminals is provided over the micro-cellular network along roads under the performance of parallel polling within LMC. One of the advantages of the unified micro-cellular network is its potential in offering more resource than double-tier network. Its main disadvantage is inefficient resource caused by parallel polling. According to our evaluation in this paper, the unified micro-cellular network can support 1000 times more channel than double-tier system does. This can compensate inefficient resource use due to the parallel polling.
