4g iot device or 5g earbuds baced on Nordic Semiconductor chips

[Tomas Adri]

Is it possible to develope a small iot device 30x30 mm with the setup as described here ?

nRF52805 and nRF9160,

needs to send and receive voice from earbuds, and music with 0,5 mbit from Spotify.

and possible the worlds first 5g earbuds ?

And maybe someone wants to join me to make this pcba and get it to mass production ?

Hello, 

I'm not sure I understand the IoT device. The nRF52805 does not support BLE audio. Please see our Audio application product page. The nRF9160 does not support voice over LTE and is not designed for music streaming, as this would be too power hungry for the applications the nRF9160 is intended for. Please see our low power cellular IoT product page for more information.

Kind regards,
Øyvind

Ok, what with the 9161 sip or 9131 mini sip ? And 5340 soc ? I can use a big battery like that in the Galaxy Watch 4...Its for transmitting 10 seconds voice commands to openai and back and Spotify 0,4 mbit streaming so we dont need a phone or a smart watch

The nRF91 series is not intended for large data throughput over LTE. It is design to handle low power IoT sensor data. If you look at our whitepaper Best practices for cellular IoT development it states a maximum throughput of 300kb/s of download speed using LTE-M, while NB-IoT (NB2) can reach 127kb/s. The device does not support the same 4G/5G technology as many mobile devices today, only LTE-M and NB-IoT (LPWAN). 

The nRF9131 is designed for DECT NR+ applications, but does support cellular as well. Note that the device will need more certification from your side if you want to use this for any type of cellular application.

Tnx, I need to make this work with the Nordic chips. So nrf 9161 supports 300 kbit download or 375 kbit ? I then need to stream directly in lc3 sound (bluetooth codec) from server. Then it can be delivered to the nrf 5340 and earbuds like Aurvana Ace directly without decoding and encoding. The voice commands can also go to the server in lc3 or wav (pcm) of maximum 20 seconds at a time.
