Last mile
The last mile or last kilometer is a widely accepted phrase used in the telecommunications, cable television and internet industries to refer to the final leg of the telecommunications networks delivery components and mechanisms to retail end-users / customers. More specifically, the last mile is the common colloquialism referring to that portion of the telecommunications network chain that physically reaches the end-user's / customer's premises. Examples are the (POTS) copper wire subscriber lines connecting telephones to the local telephone exchange; coaxial cable service drops carrying cable television signals from utility poles to subscribers' homes, and cell towers linking local cell phones to the cellular network. The word ""mile"" is used metaphorically - not literally: the length of the last mile link may be more or less than a mile. Because the last mile of a network to the user is conversely the first mile from the user's premises to the outside, telecommunications world (when said user is sending data [i.e. uploading bits]), the term first mile is also alternately used.The last mile is typically the speed bottleneck in communication networks; its bandwidth effectively limits the bandwidth of data that can be delivered to the customer. This is because retail telecommunication networks have the topology of ""trees"", with relatively few high capacity ""trunk"" communication channels branching out to feed many final mile ""leaves"". The final mile links, as the most numerous and thus most expensive part of the system, are the most difficult to upgrade to new technology. For example, telephone trunklines that carry phone calls between switching centers are made of modern optical fiber, but the last mile, typically twisted pair, telephone wiring that provides service to customer premises, essentially has remained unchanged for over a century, since the original laying of copper phone cables.To resolve, or at least mitigate, the problems involved with attempting to provide enhanced services over the last mile, some firms have been mixing networks for decades. One example is fixed wireless access, where a wireless network is used instead of wires to connect a stationary terminal to the wireline network. Various solutions are being developed which are seen as an alternative to the last mile of standard incumbent local exchange carriers. These include WiMAX and broadband over power lines applications.
