4G Arduino

Does anyone know if there are any imminent plans to release an Arduino with a 4G modem? The current cellular options are 2G/3G only and 3G will be phased out in the UK by 2022.

I guess the Arduino couldn’t handle the 4G connection. You should better use a ESP32 for that because it is a powerful microcontroller.

Why not ? The I/O connections and setup are virtually identical to earlier 2G & 3G sessions with standard AT commands. [u]Internally[/u] the modem chipset does the work of managing cells & band selection for the connection. I have literally hundreds of 8-bit AVRs on 3G & 4G without issues. The data throughput by the Arduino or other low-end processor can certainly be a limitation, but the 7600 chipset states - LTE-FDD CAT4 :150 Mbps (DL),50 Mbps (UL) The chip-to-chip serial connection may also affect reaching that capability! So - as suggested above, go ahead. They're literally a drop-in replaacement for most applications.

You seriously neglected to take into account that there are multiple MCU's available on Arduino's. They are NOT all the same. Many of those are more than capable of handling 4G data connections !

Please take this as a FINAL warning for mis-information.

4G, like other radio access technologies doesn't have to be used at the maximum possible transmission rate. The main point is that 3G won't be available in the UK after 2022. All of the operators have announced their intention to refarm the spectrum to 4G and 5G.
