The numbers listed are estimates only. Market demand and the continuing development of the technology will affect the final numbers. Additionally, unexpected events (such as earthquakes and other natural disasters) could also in demand for wireless communications,and lead to the need for additional capacity sites. The numbers supplied in the chart also subject to change if leases cannot be obtained or permits are not granted. The figures are flexible and should not be taken as"fac• . 20
