Figure 1010% percentile of packet throughput pertimeslot versus number of users. Note:90% of the packets have higher throughput.CoverageOne requirement put on EGPRS-13 6 is thatto enable an introduction in present-day cellplans and using existing base stations, thecoverage it provides must equal or surpassthat of TDMA. EGPRS with link qualitycontrol satisfies this requirement. Indeed,thanks to link quality control, poor radiolinkquality does not cause packet calls tobe dropped, but only reduces the user bitrate.A static simulation technique can be usedin coverage-limited cases, since performancedoes not depend on interference or traffic dynamics.Snapshots of the system are taken,in which stationary mobile terminals areplaced randomly according to a uniform distribution.To determine what kind of cov-Figure 11CDF of user throughput per timeslot forClassic, 4/12 frequency-reuse patternwith 5, 45, 60 and 70 users per sector.Ericsson Review No. 2, 2000 77
