An integrated wireless network with a satellite link provides connectivity within a 10km radius. A cable operator is studying three bandwidth alternatives. Assume a life of 20 years and a TMAR of 10% per year to determine the best option using the incremental rate of return approach.

Bandwidth Mbps	Initial cost $ x 1000	Cost of operation $ x 1000	annual income $ x 1000
44	-40,000	-2,000	+5,000
55	-46,000	-1,000	+5,000
88	-61,000	-500	8,000
