A WiMAX wireless network integrated with a satellite network can provide connectivity to any location within 10 km of the base station. The number of sectors per base station can be varied to increase the bandwidth. An independent cable operator is considering the three bandwidth alternatives shown below (monetary values in $1000 units). Assume a life of 20 years and a MARR of 25% per year to determine which alternative is best using an incremental ROR analysis.
