Would love any advice on Arduino cell connectivity. From what I understand:
- 2G (GSM/GPRS) is a dying technology. AT&T is shutting down its 2G network on Jan 1, 2017.
- 2G (CDMA) will have a longer lifespan than GSM in the U.S., although the options for CDMA modules are much more limited than GSM.
- 3G has poorer coverage than 2G and is no longer growing.
- 4G is overkill but is also future-proofed.
- 4G LTE ^ ditto
I am prototyping sensors that will send GPS/accel/gyro/temp data to a server every 30 seconds or so. They will be in the U.S., operate outside of wifi range, and likely not move very much (roaming isn't a factor).
Am I right in ruling out 2G GSM at this point? From what I've seen, the AT&T 4G LTE IoT Dev Kit looks like a decent option but this is the first time I've worked with IoT devices so any suggestions are welcome (http://cloudconnectkits.org/product/att-cellular-iot-starter-kit).
