Cell systems divide their service territories into many little “six equal part crystal” cell-shaped parts. This offers a great opportunity to increase a number of consumers because of used frequency repeatedly. Cell system divides its whole serving region into six equal cell parts and establishes one base station in each cell. The antenna of the base station is located on top of high buildings ...

To allow for wireless communications among a specific geographic area, base stations of communication network must be deployed to allow sufficient radio coverage to every mobile users. The base stations, successively, must be linked to a central hub called the MSC (mobile switching centre). The mobile switching centre allow connectivity among the PSTN (public switched telephone network) and the...

Double Reuse Digital Systems using Sectored Cells Yasuaki Kinoshita and David K. Asano Department of Information Engineering, Shinshu University, Nagano, Japan Abstract|To enhance frequency utilization e ciency, cellular mobile radio systems widely use a sector cell structure for the base stations. In this paper, the conceptual design formula previously reported are extended for frequency doubl...

Base stations represent the main contributor to the energy consumption of a mobile cellular network. Since traffic load in mobile networks significantly varies during a working or weekend day, it is important to quantify the influence of these variations on the base station power consumption. Therefore, this paper investigates changes in the instantaneous power consumption of GSM (Global System...

Wireless mobile backhaul networks have been proposed as a substitute in cases in which wired alternatives are not available due to economical or geographical reasons. In this work, we study the location problem of base stations in a given region where mobile terminals are distributed according to a certain probability density function and the base stations communicate through microwave backhaul...

In traditional cellular systems with fixed base stations the channel reuse pattern is static and deterministic. When the cell layout is dynamic, due to the mobility of base stations, the cluster of cells within co-channel interference range changes with time. Consequently, the channel reuse pattern is highly dynamic. Moreover, base stations also need wireless channels to communicate amongst the...
