1. A method comprising:
determining, using a location processor of a mobile device, a current location of the mobile device in a geographic area;
configuring a transmitter of the mobile device for device-to-device (D2D) communication;
determining, using one or more processors of the mobile device, one or more candidate transmit locations for D2D communication, wherein each candidate transmit location is determined based at least in part on its elevation, proximity to a D2D device density location that is within a maximum radio frequency communication distance from the candidate transmit location, and an availability of a trail or path to the candidate transmit location, wherein the maximum radio frequency communication distance is a function of transmit and receive antenna heights;
receiving input selecting a particular candidate transmit location from the one or more candidate transmit locations;
in accordance with the input,
determining, using the one or more processors, a route from the current location of the mobile device to the particular candidate transmit location; and
presenting the route through an output device of the mobile device.
