Mobile broadband: congestion is inevitable

Shown is a table listing the typical bandwidth requirements for various applications.

The table is taken from a recent report by Peter Rysavy of Rysavy Research, entitled Mobile Broadband Capacity Constraints And the Need for Optimization.

The report looks at the huge growth in mobile broadband services and the resulting congestion. The report includes a nice model showing how only a few intensive users can consume much of a cell's capacity. The report also discusses how operators must continue to add wireless capacity while being a lot smarter in the bandwidth consumed by applications.

Is "high speed internet" an application? Web browsing is an application, HD TV is an application, the internet is a system of interconnected computers and servers - a physical thing. What applications will people run on "high-speed internet" is a question that is rarely answered well.

The previous comment is correct: "high speed Internet" is not an application. I included internet speeds in that table in my report as a reference point for the other applications listed.
