Scanning network, frequencybands before you can register is a process that can consume quite some energy.
In the Netherlands we got good coverage, but that is not the same all over the world. I am looking for a way to reduce energy waisted - e.g. by using special AT commands or algorithmes that reduce the energy used to get registered.
Worst case is that my device, in the middle of nowhere, keeps looking for a network if it is not there,
