1. Example of BS sleeping scheme with coverage extension Hence, cooperation among BS is significant to maintain the availability cellular access over the service area. The specific system parameters used for making the switching decision, have to be determined. Since in low-traffic periods, most BSs will be able to be easily switched to sleep mode, identifying the best BS set to switch off is a major challenge. Furthermore, consideration needs to be given to key parameters which directly impact on network performance, such as traffic load and interference. Especially, our consideration of the UMTS radio access network and count up the likelihood to turn off BS equipments. Through this paper, we claim that concept of cell zooming can be applied to a real central business district (CBD) network by adding new software features and switching-BS equipments. II. NETWORK LAYOUT, ARCHITECTURE, AND CELLULAR MODEL A. Network Layout In this paper, using central business district (CBD) scenario of BS’s environment. CBD is focal point of a city which comprises office, commercial space, culture center, public park, and center point for transportation networks. Fig. 2. Network layout of CBD environment in Surabaya B. UMTS Radio Access…show more content…
user information bits are spread over a wide bandwidth by multiplying the user data with quasi-random bits (called chips) derived from CDMA spreading codes. In order to support very high bit rates (up to 2 Mbps), the use of a variable spreading factor and multicode connections is supported. In case the connection uses avariable spreading factor, the proper use of the code tree also allows despreading according to the smallest spreading factor. This requires only that channelisation codes are used from the branch indicated by the code used for the smallest spreading
