Schematic representation of the management of incoming calls with and without Power Saving. Each row represents a TRX and each square a TS. Thus, this scheme represents a cell with three TR Xs and 8 TS per TRX. Controls occupied by TSs are indicated with C, and TSs occupied by transmission are indicated with X. a) No PS: new calls are randomly occupied. b) PS: occupied TS are re-allocated in the first TRX. The last TRX remains unused and can thus be switched off.

Telecommunications power systems have seen an increasing energy demand in the last few years, with an exponential growth of base transceiver stations, due to the development of new mobile telephony technology and the continuous evolution of mobile services. "Power saving" is one of the most important approaches to reduce energy consumption, in part...

... are no clear weekly fluctuations of the average call length. The network designer set the best Grade of Service (GoS), i.e. the minimum amount of technical issues for the customer, while maintaining technical and economical sustainability, by planning for a suitable number of TS channels in the cells and fine-tuning the transmission parameters. Fig. 2a is a schematic view of a typical cell, with 3 TRXs (the rectangular rows) and 8 TSs (squares) per TRX. In the first TRX, there are two control TS, labeled "C ", and 6 more TS, three of which are occupied by a call, indicated with an ...

In recent years, there has been an increase in the number of studies on biological effects of Electromagnetic (EM) fields emitted from Base Transceiver Stations (BTSs). The biological effects of generated and real telecommunication signals produced by different types of exposure systems are discussed. However, the proper exposure methods for such e...

Gaza Strip suffers from a chronic electricity deficit that affects all industries including the telecommunication field, so there is a need to optimize and reduce power consumption of the telecommunication equipment. In this paper we propose a new model that helps GSM radio frequency engineers to choose the optimal value of hysteresis parameter for Ericsson BTS power saving algorithm which aims to switch OFF unused frequency channels, our model is based on unsupervised machine learning clustering K-means algorithm. By using our model with BTS power saving algorithm we reduce number of active TRX by 20.9%.
