The company I work for wants to make a wearable personal (care)alarm device for use outside, think of an elderly person who is still mobile but is prone to falling. This device can be used by that person to call for help when they have fallen. The nRF9160 looks like a good choice because of its low power consumption, because the device we want to make will be idle/asleep most of the time, only when the user pushes the button will it wake up.
This application might be outside the applications where the nRF9160 was designed for, therefore I like to know if the following can/will work and if someone has tried it and has any experience with it.
- Can the nRF9160 do continuous full duplex audio streams over the LTE connection (viop)?
- I don't care about data consumption or the fact that this might use a fair bit of battery power
- Is the processor powerful enough to not only (de)compress the audio but also do echo cancelling?
- Not really an easy one to answer, I know.
- Or would it be better to let an other CPU handle that part?
If anyone can provide me with some insights to this, that would be much appreciated.
