Experimental Analysis of Voice and Data Transmission Parameters for Mobile Terminals in Cellular Data Networks

“…In this work is just used mode BLER to prove the capacity of reception in the mobile terminal, to GPRS contains different modulation schemes, to compensate the errors in the transmission in respect to the distance increase. [6,7]. The modulation scheme that it is used first is CS-4, it has the highest bit rate transmis- sion of data, that scheme is used when the base station is closer to the mobile device.…”

“…The modulation scheme CS-1 is the most robust, because it has more bit of redundancy, but it presents the lowest bit rate transmission. [6,7]. When the station mobile works with CS-1, the terminal presents errors in -76 dBm.…”

“…Subsequently, we introduce the mobile terminal within the shielded box and the Analyzer proceeds to Register the equipment under test, and once this is done, the Communication mode is set indicating that the equipments are linked and data transfer can take place. In this case, due to the characteristics of the measuring equipment, we can only test the downlink 384 Kbps theoretical speed [6,7]. The power level configuration of the base station and mobile terminal was carried out according to what is specified in Figure 11.…”
