“…Besides the considered factors, which have influence on the mean value of output power of each channel, two more factors have influence on the mean BTS output power: part of intra-cell connections, [4] and [9], and the use of one channel for two connections (half rate), [10] - [12]. Intra-cell (or internal) connections in the cell always exist, but in different percent.…”

“…In order to reduce losses caused by the lack of channels on Air-interface, dynamic channel allocation with half rate (HR) is often used, [1], [10], [11], [12]. Usage of HR connections by the implementation of repacking channel assignment is considered in this paper.…”

“…Usage of HR connections by the implementation of repacking channel assignment is considered in this paper. (Repacking scheme of HR channel assignment means that one time slot is used for two HR connections, [11], [12]). It is clear that mean output power of one channel w 1m is divided on two connections.…”

Original scientific paperThis paper compares the influence of various factors on the output power of each GSM channel and connection, and on the output power of whole base transceiver station in GSM network. The considered factors are the influence of sending signal only when speech exists (DTX), implementation of power control in signal sending, influence of users' distribution in the range of coverage of base station, the power of one intra-cell connection and the power of one half-rate connection. It is analyzed how emission power of base station can be reduced by implementing various methods in signal sending.

“…Saving of traffic resources is achieved by implementation of small bandwidth coders/compressors and by implementation of half-rate coders. Half-rate coding decreases bandwidth per user to one half in the relation to the standard implemented coding/compression method [8,9]. As the parallel positive effect of half-rate coding implementation, the BTS total emission power is also decreased.…”

This paper presents simulation model for the analysis of characteristics of base station, which may establish half-rate connections. Accuracy of realized simulation model is analyzed comparing its results to a number of corresponding results, which are obtained by calculation or presented in referenced literature. These corresponding results are obtained, in the first case, analytically, solving the system of equations, which are modelling the system and, in the second case, from the literature, which deals with the similar systems. At the end, simulation model is implemented to analyze in detail several systems with different total number of traffic channels. The results of simulation pointed out how much probability of connection loss decreases in the case of great traffic load, when half-rate connections realization is implemented.
