Future 4G cellular systems will address the need of capacity increase for the support of diverse Internet services. This article deals with cell capacity issues and cell planning for LTE technology. The Soft Frequency Reuse (SFR) scheme is considered here as an interesting approach to efficiently utilize the bandwidth in LTE systems. With SFR, a cell is divided into two parts (the central part and the external part) using different reuse schemes. On the basis of a suitable path loss model, we have been able to characterize the Signal to Interference plus Noise Ratio (SINR) and the probability to use different transmission modes in a cell with SFR. This has allowed us to evaluate the capacity of a cell that can be achieved with SFR. Finally, a cell capacity optimization has been carried out by means of extensive numerical results in order to select both the radius of the cellcenter region and the border-to-center power ratio of SFR.

This paper presents a new use of double queues asymmetric gated service polling system in the intelligent traffic light control system.Usually there are more vehicles in main road than minor road,so there are more green light time be needed in the main road.From the computer simulation and theory analysis,we can find that the application of double queues asymmetric gated service polling theory in intelligent traffic system can balance intersections load and set suitable passing time for vehicles to assure the roads open.Keywords:gated service; intelligent traffic; polling; arrive rate; waiting time; IntroduceWithing the development of urban economy, the city scale expands unceasingly,the vehicles also become more and more,but when people enjoying the convenient that vehicles bring,at the same time,also meet more and more problems,such as air pollution,noise pollution and traffic congestion.
