RAK7249 queries

I have below few queries before we can buy the RAK7249 gateways. Please help me answer them asap.

  1. which LTE bands are supported ?

  2. initially my gateway would be connected using ethernet, in case ethernet fails I want the gateway to switch to LTE seamlessly and send data over LTE without data loss, is this seamless failover between ethernet and LTE possible?

  3. Can we login (ssh) to gateway over LTE while ethernet is working ?

  4. Are third party operator sims supported ?

  5. Can we hard reboot the gateway without opening it ?

  6. Can we reset the gateway without opening it ?

  7. Can ethernet, wifi and LTE all work at the same time ?
