IND FO/OP Co-located 2G/3G sites Stand alone 3G sites Stand alone 2G sites In Table 7.27 the number of sites are cumulative. The totals can be summarized as fol- lows: 2002 co-located = 825, stand alone 3G = 194, stand alone 2G = 282. Total 2002 = 1301. 2005 co-located = 828, stand alone 3G = 591, stand alone 2G = 284. Total 2005 = 1703. Therefore, the 2002 sites grow to 1703 by 2005 in this example.

Values are absolute figures. Deploying 3G Networks Table 7.29 Microwave Links for 2002 and 2005 U/IND FO/OP 2x2Mbps 4x2Mbps 8x2Mbps 16x2Mbps Total The MW frequencies will vary from region and/or country to country. For example in Switzerland, the last mile access links in dense urban, urban and industrial areas will most likely use 38 GHz. In suburban, forest and open areas links will use 23 GHz. However, these frequencies are subject to change depending on the radio frequency availability. 7.10.3.3 Leased Line Network Table 7.30 illustrates the number of projected leased lines for 2002 and 2005. Values for each site category are shown, and are absolute figures: Table 7.30 Leased Line Projections (E1s) for 2002 and 2005 U/IND FO/OP Co-located 2G/3G sites Stand alone 3G sites Stand alone 2G sites Taking into account the information of Table 7.29 and Table 7.30, we illustrate the pro- jected capacities for the regional rings in Table 7.31.
