Modems
Don't buy modems if you can avoid it
- Avoid modems wherever you can. Always try to buy "gateways" or "routers"
- Avoid "NB-IoT" or "LTE Cat M1" devices (modem/gateway/router)
- These are low power, low bandwidth devices
- While Ardexa should work, the bandwith is insufficient to support smooth remote operations, particularly tunnel/VPN
- See https://www.cablefree.net/wirelesstechnology/4glte/lte-ue-category-class-definitions/ for details on the different LTE categories.
