| 0:00.0 | The term Last Mile has traditionally been used within the world of telecommunication services, |
| 0:20.0 | in reference to |
| 0:21.2 | the final portion of infrastructure required to connect an individual or household to an information |
| 0:27.5 | services node. In practice, that might mean figuring out how to wire up a house for cable |
| 0:32.7 | TV or getting internet connectivity to a particular apartment or house or business. It's a relatively |
| 0:39.0 | simple thing comparatively to get internet connectivity to a company-owned antenna or other hub. It's |
| 0:46.2 | a lot more difficult to then get that connectivity out to every single possible customer in a region, |
| 0:52.3 | because of the immense variability in what will be required to reach |
| 0:56.2 | all of those people. In some cases, many miles of extra fiber optic cable is necessary to reach |
| 1:02.8 | a remote farmhouse, and in others, cables have to be snaked around electrical poles and up and |
| 1:08.4 | through old crumbling brick walls to get where they need to be, |

| 1:34.2 | wirelessly. And this, despite the extra costs, often associated with this method, and the quite |
| 1:40.8 | often, at least, reduced quality of those signals compared to the hardwired |
| 1:45.9 | alternatives. In other cases, entire regions will go unserved by local purveyors of electricity |
| 1:53.1 | and internet and waste collection, because that last mile, that final bit of distance between |
| 1:59.3 | them and the rest of the service providers' |
| 2:01.6 | infrastructure is just too difficult or costly to traverse. |
| 2:06.6 | The term last mile is also used in the world of transportation, especially in towns |
