Broadband plans with data caps are cheaper by up to 25% than unlimited plans, according to a just-released study from the Technology Policy Institute.
The institute's supporters include the National Cable & Telecommunications Association, Comcast, Time Warner Cable, AT&T and Verizon.
The study also found that broadband plans with contracts are cheaper than those without them.
Residential standalone plans with caps average $164 less per year than comparable unlimited plans, the study concluded, while bundled "triple play" plans with caps are about $152 less per year.
The study was of residential and business broadband prices in the U.S. and abroad.
The bottom line of the study: "Policymakers should not immediately conclude that data caps and other pricing schemes that differ from traditional unlimited plans are necessarily bad."
