Last Mile

What Does Last Mile Mean?
A phrase used in the telecommunications and technology industries to describe the technologies and processes used to connect the end customer to a communications network. The last mile is often stated in terms of the "last mile problem", because the end link between consumers and connectivity has proved to be disproportionately expensive to solve.

As a result of this, there are many publicly traded companies engaged primarily in "last mile" solutions and services.
