Nortel s Vision of 3GPP2 Evolution With similar throughput performance, 1XEV-DO Rev 0 & Rev A are about 18 months ahead of HSDPA/HSUPA. 3GPP evolution intends to close Gap with HSUPA and lead beyond HSUPA MC-DO provides higher user throughputs than 3GPP and comparable peak rates while preserving investment protection (Mid term recommendation) B-OFDM offers significant performance gain but would require physical layer change. Nortel recommends an aggressive evolution vision, using MIMO OFDM for delivery in the 2009+ timeframe. 6 1x DO RevA 1.2 1.25MHz CDMA 3.6x MC-DO 1.25, n x 1.25 MHz CDMA (N=1 3) Ultra Broadband Wireless 3G 4.7x throughput Peak: rates of 16 Mbps B-OFDM OFDM Mix of 1.25 MHz CDMA or OFDM, 5, 10, 20 MHz OFDM 10x/20x throughput Peak: rates of 40 Mbps MIMO-OFDM OFDM (2x2 / 2x4) MIMO OFDM optimized A/I
