Internet Connection

The smart-me system and its hardware require a direct internet connection to the cloud. On site, you therefore need to provide a 2.4GHz WLAN with an internet connection. 5GHz is not supported due to its limited range.

Internet access can be provided as follows:

  • A cable provider offering from Telekom, Vodafone, 1&1 or another local internet provider and a 2.4GHz WLAN router, usually supplied by the provider.

  • Set up internet via a mobile SIM card and a 2.4GHz WLAN router.

Redundancy levels

  • Provide several access points with the same SSID and password. All smart-me products automatically select an access point with an internet connection.

  • Store several WiFi networks on the smart-me device: Can I use my device with several WiFi networks?

Hardware requirements​

Key points*:

  • Standard: 802.11 b / g / n

  • WiFi frequency: 2.4 GHz

* further details can be found in the technical data of the respective products.

Specifications as required:

  • Number of clients supported in parallel.

Clients: The supported clients define how many devices can communicate with the access point or router in parallel. The number must suit your installation. There are cost-efficient access points that support 200+ clients. The number can be found in the device data sheet, usually under "Max. Clients" or "Concurred Clients".

Possible hardware components​

Router​

The router is the source that is connected to the internet/provider and converts it into LAN (RJ-45) or WiFi 2.4 Ghz / 5 GHz.

Access points​

Access points convert a signal passed on from the router via LAN (RJ-45) into a 2.4 GHz / 5GHz WLAN.

Repeater​

Repeaters amplify an existing WLAN signal to extend its range.

Mobile LTE router with 2.4GHz WLAN​

Teltonika RUT241 (max. 50 clients)

An external SIM card slot and signal strength LEDs make commissioning easy. The router's 4G module offers LTE Cat 4 speeds of up to 300 Mbps. Alternatively, the device can also be used as a DSL router or WLAN client and has a fallback function that automatically switches to LTE or WLAN if the DSL connection fails.

  • Teltonika RUT241 (max. 50 clients)
  • Teltonika RUT951 (max. 100 clients)
