We are looking for a competent engineer to design a wireless proximity device system. the system would frequently bounce signal from a module to the proximity monitor. When the signal is not returned, the wireless module alerts the network with its current GPS location. The network can entail a smart phone or a monitoring station.
I am open to suggestions on the on type of wireless transceiver to use.
The specifications include
low power consumption module
Module should be self powering
Module optionally can use mobile network sim to dial location in.
the system should be robust
The smart phone app would need to be developed or at least provide a way to allow the system to function with smart phone app.
