Abstract: This paper presents the results of measured TCP performance in the LA process during the deployment of GPRS CS1 and CS2 coding schemes and after the activation of two more coding schemes, CS3 and CS4. The measurements are carried out in one of the commercially deployed live GPRS networks in Malaysia, using end-to-end FTP file transfer application for the assessment. Tracing at the GPRS air interface is done simultaneously. The results show that TCP works well in the LA process and can adapt to the frequent switching between the coding schemes without any problem. The average throughput is increased by 23% for urban areas owing to the activation of higher coding schemes and aided by TCP tuning. It is also shown that throughput is limited by the current coding scheme used and good channel condition is necessary to optimize TCP performance.
