2.4.3 Cellular Network
The WebdynEasy W M-Bus hub includes a 2G, NB-IoT and LTE-M network compatible modem.
2.4.3.1 Antenna
The hub has a female SMA connector labelled “4G” on the board to connect a modem antenna. The
product is delivered with an internal antenna. An external antenna can be connected to the product. To
do this, unscrew the cap on the box and fit a M16*1.5 cable gland (not included).
If the WebdynEasy W M-Bus hub were to be installed in a metal box or in a location that does not
have proper signal reception, the use of a remote antenna is strongly recommended. Be careful to use
an antenna compatible with the connector and frequencies used.
In the new box, the cable gland is optional and is installed after breaking the breakable part provided in
the box.
End users must make sure their installation using remote antennas meets applicable EMC
standards.
2.4.3.2 SIM Card
To use the LTE-M, NB-IoT or 2G modem connection to allow the hub to communicate with the remote
server, the box must be opened(see section2.3.1: “Opening/closing the box”) and a mini SIM card
inserted into the SIM card housing inside the hub.
The hub is compatible with all market operators as well as with all mini SIM 2FF 25 x 15mm format SIM
cards.
