Comcast Launches Usage Meter: Some Users Might be Surprised

Comcast is launching a "free to use" data usage meter in the Portland, Oregon market, with plans to roll the application out nationally. . The meter will help customers understand how much data they consume in a month. It is an essential sort of tool if users someday are required to buy data packages the way they buy mobile buckets of voice and data.

That is not to say Comcast has any current plans to do so; simply to point out that since few, if any, consumers know what their usage pattern actually is, they certainly cannot be expected to be rational consumers of subscription plans that require such knowledge.

Nor will most users have any problems, even if retail pricing plans were to change, someday. Comcast defines "excessive use" as consumption above 250 gigabytes a month, and the median usage for Comcast’s customers at present is about 2 to 4 Gbytes a month.

The meter is accessible by logging in to "Customer Central" at http://customer.comcast.com and clicking on the “Users and Settings” tab. From there, click on “View details” in the “My devices” section (located toward the upper right hand of the screen) and that will go to the meter page. The meter will show usage in the current calendar month when it’s first launched. Over time, it will show the most recent three months of use (including the current month). The data is refreshed approximately every three hours.

The meter measures all data usage over a cable modem, including any other devices connecting using Wi-Fi. Online gaming consoles, smartphones using Wi-Fi,  digital video recorders, printers, cameras or the iPod Touch are examples.

The Windows operating system and most popular software applications have automated update programs. These updates often download and are installed automatically without the need for user intervention. The automation is generally designed for the convenience and protection of the consumer, but the traffic it generates may come as a surprise.

Cable modem connections supporting multiple PCs will have a correspondingly higher amount of such update activity.

Aggressive update settings, with some default settings checking each hour and downloading every possible option even though they are not all needed, could cause unexpected levels of traffic.

For example, a software program may load its interface in a dozen languages even though all household members only know how to read English.

Another possible “surprise” upstream traffic source is online file backup or uploading to photo sharing sites. Also, many news and information services preload content onto their subscriber's PC or smart phone over the Wi-Fi home network. The content often arrives overnight for convenient viewing in the morning.

Assume each night's upload is only 1GB, which takes up a modest 1GB on the device's storage, and assume too that it never consumes more than 1GB because it overwrites the old content with fresh content each night. That can add up to 30GB over a month on the meter.

A large volume of traffic may be going to digital video recorders such as TiVo. A user in the home may have rented a movie from Amazon, Netflix or Blockbuster. Renting the movie will be a known traffic-generating event. But many services also preload the start of other movies as well as trailers to make them instantly available should they be called for.

The meter will be a useful tool for managing both intended and unintended bandwidth consumption.
