Satellite capacity is the biggest running cost of the teleport business model. In research for its 2011 Top Operator rankings, WTA asked respondents to share in confidence information on gross revenues and annual spending on satellite capacity. Respondents spent an average of 47% of revenue on satellite capacity and capacity spending ranged from a low of 14% of revenues to a high of 79%. In this newest report, WTA focuses on the actual terms of capacity contracts that can create potential harm or advantage for the teleport operator, from ramp ups to termination clauses, portability to quality of service.
