Tables 7.20 and 7.21 illustrate uplink and downlink values to serve as comparative reference. Some of these values are round-off from earlier dimensioning exercises to provide generic illustrations of multi-service budget link results [7]. 7.8.2.2 RNC Dimensioning for 75% Coverage Following the principles to dimension the RNC, here we illustrate some results based on the traffic figures illustrated in Table 7.11. We calculated the average throughput per city, at busy hour, both PS and CS traffic. Table 7.18 illustrates the traffic split in the reference cities. Table 7.18 Subscriber Traffic and Site Split Reference 75% (2005) Location User traffic Site split Average total PS Average total CS split (%) throughput (Mbps) throughput (Mbps) City A City B City C Total Table 7.19 illustrates results of the reference examples based on the site distribution illustrated in Table 7.18 and the aforementioned steps for RNC dimensioning.
