1. A method comprising, at a mobile device:
- receiving via a wireless communication signal, from a route server that is separate and external to the mobile device, at least a portion of a planned route to a pre-determined destination, said received at least said portion of said planned route comprising indicators for travel within a location of at least one harsh or diminished radio frequency environment;
said received at least said portion of said planned route comprising an instruction to activate at least one sensor if an estimated position of said mobile device is proximate to or approaching said location of at least one harsh or diminished radio frequency environment;
processing acquired satellite positioning system (SPS) signals, terrestrial positioning system (TPS) signals, or a combination thereof, for use in computing said estimated position of said mobile device;
said mobile device activating, said at least one sensor in response to said instruction based, at least in part, on a determination that said estimated position of said mobile device is proximate to or approaching said location of at least one harsh or diminished radio frequency environment; and
using measurements obtained at said activated at least one sensor to aid in obtaining a position fix within said location of at least one harsh or diminished radio frequency environment.

Abstract
Methods, apparatuses, and devices for generating one or more harsh or diminished radiofrequency environments relative to a planned route of a mobile device user. In one example, a mobile device user a be routed through a harsh or diminished radiofrequency environment based, at least in part, on a sensor suite of a mobile device and/or based on a user'"'"'s preferences. Prior to entry into such an environment, various sensors may be activated in a manner that permits position estimation in an absence of SPS based positioning signals and/or TPS based positioning signals.
