Where did the target pricing for cost/Mbps and cost/connection come from?

EducationSuperHighway analyzed the prices that school districts are paying across the United States for Internet access and wide area network connections and identified the average cost within the 30th percentile. The 30th percentile became our pricing targets, averaging $3 per Mbps for Internet access and $750 per connection for a 1 Gbps WAN connection.

The $3 per Mbps metric represents a price at which the E-rate program can support all school districts meeting the FCC’s 2018 goal of 1 Mbps per student and is a price already being achieved by over 32% of school districts purchasing 1 Gbps or more of Internet access.
