Abstract

A method can include, by operation of controller circuits, determining a higher interference resistance (HIR) location coordinate (PIN) for a route between the wireless device and a target location. A wake message can be transmitted according to a first wireless protocol. In response to receiving an awake message according to a second wireless protocol, a location and quality value for the awake message can be stored. In response to being within a predetermined proximity of the HIR activation PIN without having received the awake message, a HIR wake message can be transmitted. In response to acquiring stored location and quality values, an HIR activation PIN can be selectively changed. A first wireless protocol can consume less power or be less resistant to interference than a second wireless protocol. Corresponding devices and systems are also disclosed.

Dependent claims

A method, comprising:

by operation of location circuits of a wireless device, determining a location of the wireless device and location error for the location;
by operation of controller circuits of the wireless device, determining a route between the wireless device and a target location that includes at least one higher interference resistance (HIR) location coordinate (PIN) based on at least the location error;
by operation of wireless circuits, transmitting a wake message having at least a wakeup code according to a first wireless protocol;
in response to receiving an awake message according to a second wireless protocol, storing a location and quality value for the awake message, the awake message corresponding to the wakeup code;
in response to being within a predetermined proximity of the HIR activation PIN without having received the awake message, transmitting a HIR wake message according to the second wireless protocol;
and
in response to acquiring a plurality of stored location values and corresponding quality values over time, selectively changing the HIR activation PIN;
wherein
the first wireless protocol consumes less power or is less resistant to interference than the second wireless protocol.
