Communication ports
All communication ports are protected and requires a proper identification to work.
In case of uninstalling the product from the water pipes and prior to send it by air transportation, un-
sure that you have desactivated all the radio.
Bluetooth Low Energy PAN radio (if product is so
equipped)
The meter can include a local Personal Area Netwrok made by a Bluetooth Low Energy port.
The BLE implementation is Bluetooth ® 5.2 certified working in the 2400
– 2483MHz ISM frequency
band and uses a integrated antenna transmitting less than +10 dBm EIRP for short distance communi-
cation only.
This local BLE can be used through a Mobile Phone application to read and write informations into the
applicative part of the device. The BLE range is more than 3 meters and depends of the installation
place and the mobile equipment.
To enable the BLE broadcast, prepare the Mobile App, and push the button of the meter. Within few
seconds, the APP should locate the meter and enable communication. Take care to activate the local
BLE feature before hand if not already done. The access is protected by individual credential.
Note that WAN communication is disabled during the BLE activity. WAN communication is resumed
only once BLE is disabled.
For security reason, the minimal distance to respect between the meter and the human body is 31 cm
(1 feet).
Infrared communication port
An optical port compatible with IrPHY SIR 115.2kb/s could be available. This port can be used to read
and write information into the applicative part of the meter. The access is protected by individual cre-
dential and must be activated.
To reduce power consumption, the infrared is disabled most of the time. A button press must be per-
formed to activate infrared for a 10 sec window. If a communication exchange is detected, the meter
extends the activation timeout accordingly
Remote CAT-M
™ WAN radio
The Wide Area Network radio communication port is based on a LTE 4G Cat-M1 into the band 4 &13.
