ayer transmission. Uplink peak data rates for 20 MHz spectrum allocation, assuming that two long blocks in every sub-frame are reserved for reference signals and a code rate of 1, provide the following results: 57.6 Mbps with 16QAM. 86.4 Mbps with 64QAM. Spectral Efficiency for Case 1 (500 m inter-site distance) and Case 3 (1732 m inter-site distance) are shown in Table 3.10. In simulations E-UTRA 1 X 2 configuration reflects one TX antenna in the UE and two receive antennas at the eNodeB. Average Cell throughputs for downlink and uplink are shown in Figures 3.35 and 3.36. VoIP Capacity results are shown in Table 3.11. Assumptions related to VoIP traffic model include Full rate AMR with 50% VAF) and outage (95% coverage for 2% FER @ 50ms delay bound) for all simulations. The differences between VoIP capacity estimates for the two cases are due to differences in assumptions on scheduling, control channel limitations and operating IoT22 and distance as listed in [3,11]. 3.10.2 Field Testing Operators and vendors had been measuring the performance of EPS in particular E-UTRAN in the field since 2009. Along the same lines, Telenor Group is currently testing Ericsson and Huawei LTE equipment. In this section we will briefly describe the field testing efforts of NSN (Nokia Siemens Network) that were made during 1Q09.2 23 22 IoT (interference over thermal) indicates the ratio between the total received interference power and the thermal noise. 23 These were early indications of LTE performance in field conditions. These measurements will improve with Flexi Next Generation Mobile Communications Ecosystem Table 3.10 LTE spectral efficiencies LTE Downlink Spectral Efficiency Case 1 (500m ISD) Case 3 (1732m ISD) Spectral Efficiency Spectral Efficiency Configuration (DL) [bps/Hz/cell] (DL) [bps/Hz/cell] UTRA baseline 1x2 E-UTRA 2x2 SU-MIMO E-UTRA 4x2 SU-MIMO E-UTRA 4x4 SU-MIMO LTE Uplink Spectral Efficiency Case 1 (500m ISD) Case 3 (1732m ISD) Spectral Efficiency Spectral Efficiency Configuration (UL) [bps/Hz/cell] (UL) [bps
