From "AVweb":


The FAA has estimated overall costs on the user end could range from
$2.5 billion to $6.2 billion overall. And the FAA currently plans to
mandate only ADS-B Out by 2020. However, ADS-B Out "essentially
replicates existing domestic radar coverage," meaning adopters would
bear a cost but see few new benefits.


I'm reminded of the situation that has existed with personal computers
for decades: advanced computers with more powerful processors (8 bit,
then 16 bit, 32 bit, and now 64 bit) appear on the market years before
the software is able to take advantage of the added power. While
proponents of ADS-B point at how well the hardware (ground stations,
e.g.) is being implemented, it appears the people, protocols, and
software are lagging significantly behind.
