One of the commenters on my blog asked a good question – can’t we set the definition of broadband by looking at the broadband applications used by the typical household? That sounds like a commonsense approach to the issue and is exactly what the FCC did when they set the definition of broadband to 25/3 Mbps in 2015. They looked at combinations of applications that a typical family of four might use in an evening, with the goal that a household ought to have enough broadband to comfortably do those functions at the same time. This might best be described as a technical approach to defining broadband – look at what households are really using and make sure that the definition of broadband is large enough to cover the expected usage for a typical household.
Taking this approach raises the bigger question – what should the policy be for setting the definition of broadband? I don’t know that I have any answers, but I ask the following questions:
- The FCC largely conducted a thought experiment when setting the 25/3 definition of broadband – they didn’t try to measure the bandwidth used in the scenarios they considered. If the FCC had measured real homes doing those functions they likely would have found that bandwidth needs were different than they had estimated. Some functions use less bandwidth than they had supposed. But usage also would have been larger than they had calculated, because the FCC didn’t compensate for WiFi overheads and machine-to-machine traffic. As a household makes use of multiple simultaneous broadband functions, the WiFi networks we all use bog down when those applications collide with each other inside the home network. The busy-hour behavior of our home networks needs to be part of a mathematical approach to measuring broadband.
- The FCC could have gotten a better answer had they hired somebody to measure evening broadband usage in a million homes. We know that broadband usage is like anything else and there are households that barely use broadband and others that use it intentsely. The idea of pinpointing the usage of a typical family is a quaint idea when what’s needed is to understand the curve of broadband usage – what’s the percentage of homes that are light, average, and heavy users. I’m sure that one of the big companies that track broadband usage could measure this somehow. But even after making such measurements we need a policy. Should the definition of broadband be set to satisfy the biggest broadband users, or something else like the medium speed used by households? Analytics can only go so far and at some point there has to be a policy. It’s not an easy policy to establish – if the definition of broadband is set anywhere below the fastest speeds used by households, then policy makers are telling some households that they use too much broadband.
- If we are going to use measurements to determine the definition of broadband, then this also has to be an ongoing effort. If 25/3 was the right definition of broadband in 2015, how should that definition have changed when homes routinely started watching 4K video? I don’t think anybody can deny that households use more broadband each year, and homes use applications that are more data intensive. The household need for speed definitely increases over time, so any policy for setting a definition of broadband needs to recognize that the definition must grow over time.
- One fact that is easy to forget is that the big cable companies now serve two-thirds of the broadband customers in the country, and any discussion we have about a definition of broadband is only considering how to handle the remaining one-third of broadband users. There is a good argument to be made that the cable companies already define the ‘market’ speed of broadband. The big cable companies all have minimum broadband speeds for new customers in urban markets today between 100 – 200 Mbps. The companies didn’t set these speeds in a vacuum. The cable companies have unilaterally increased speeds every 3-4 years in response to demands from their customers for faster speeds. I think there is a valid argument to be made that the market speeds used to serve two-thirds of the customers in the country should be the target broadband speed for everybody else. Any policymaker arguing that 25/3 Mbps should still be the definition of broadband is arguing that one-third of the country should settle for second-class broadband.
- In a related argument I harken back to a policy discussion the FCC used to have when talking about broadband speeds. I can remember a decade or more ago when the FCC generally believed that rural broadband customers deserved to have access to the same speeds as urban customers. That policy was easy to support when cable networks and telco copper networks both delivered similar speeds. However, as cable broadband technology leaped ahead of copper and DSL, these discussion disappeared from the public discourse.
- When looking at grant programs like the upcoming RDOF program, where the funded networks won’t be completed until 2027, any definition of broadband for the grants needs to look ahead to what the speeds might be like in 2027. Unfortunately, since we can’t agree on how to set the definition of broadband today, we have no context for talking about future speeds.
These are not easy questions. If the FCC was doing its job we would be having vigorous discussions on the topic. Sadly, I don’t foresee any real discussions at the FCC about the policy for setting the definition of broadband. The FCC has hunkered down and continues to support the 25/3 definition of broadband even when it’s clear that it’s grown obsolete. This FCC is unlikely to increase the definition of broadband, because in doing so they would be declaring that millions of homes have something less than broadband. It seems that our policy for setting the definition of broadband is to keep it where it is today because that’s politically expedient.
