| With the statistical study and analysis of the current model of 10mW base station on whole wireless network of Xi' an Personal Access System , some aspects of processing, wireless side Enlang have been calculated .calling lose and phone mode of users decided, and hot saying distributing discussed. Based on the mentioned facts and considering the ratio of certain base stations,emphasis is especially placed on figuring out the needed amount of 500mW based stations when services for 250 thousands users are presented. Furthermore, the 500mW base stations for 400 thousands scenario users have been obligated and calculated, and the base station controller has been reckoned respectively. A blue print of the suited network has been set down, according to wireless layout principle, where after, a feasible connected network scheme framed, in the light of practical project. The main advantageous features of this project lie in the fact that it has resolved the problems of the lOmW base stations, such as limited coverage areas, few channels, poor signal on high way and in high speed car, easily turn off and frequently switch etc. The processing response of 500mW base stationinstead of 10Mw base-station, has effectively accounted for nearly all of the relative defects.The technical and economic incentives that are associated with the transformation have provided the basis for the present study, i. e. , 1) signal overcastting areas increased and its quality improved notably, also blinding areas lessened, switching frequency and losing ratios of mobiles decreased. 2) the quantity of EAL increased largely compared with the former set, for example each base station elevation 13%. 3) operation receipt enhanced by 20%. 4) practically the amount of users fortified . 5)customers' appeal reduced greatly, thanks to the improvement of the reliability of overall set and good service of it. All of this has brought about great convenience on the part of the users and profits on the part of the enterprises. This project is very efficient and opens up new possibilities to enlarge the amount of users and guarantees good services to the consumers . |
