Ready-to-Use Room & Equipment Monitoring with Cellular IoT Devices

ECOLOG-PRO xG is using 4G Mobile IoT (LTE-M/NB-IoT) for communication. Mobile IoT is for transmitting low amounts of data (machine-to-machine) on long ranges with low power consumption. The protocols are standardized by 3GPP and currently rolled out globally. LIBERO G as well as ECOLOG-PRO xG talk both "languages" (protocols) LTE-M and NB-IoT. The devices are able to automatically switch between the two (e.g. in case of no connection).

Long Term Evolution for Machines (LTE-M) is a low-power wide-area network radio communication technology standard which supports IoT through lower device complexity and provides extended coverage, while allowing the reuse of the LTE installed base (=4G). LTE-M facilitates an energy-efficient handshake between antennas and is therefore optimized for mobile applications.

Narrowband Internet of Things (NB-IoT) is a low-power wide-area network radio communication technology standard developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage. Ideal for utility metering. It uses widely available infrastructure, consumes very little energy, keeps device and deployment cost low, can reach deep within buildings and can support large numbers of units. NB-IoT is typically used for stationary applications.

Started data logger runs up to 14 months with LiFe batteries (batteries are exchangeable).

A use below 0 °C and above +40 °C over a longer period of time and / or intensified communication behavior (e.g. bad connection) can shorten battery life.

The power management of ECOLOG-PRO xG has certain mechanisms (e.g. reduced communication interval for bad connection) to ensure the stated runtime.

Consult the country list to check connectivity quality. In any case, we recommend performing a test on the planned installation location.

ECOLOG-PRO xG operates in the public cellular network (LTE-M and NB-IoT). This network allows high penetration and connection also within buildings. As ECOLOG-PRO xG operates in a licensed spectrum, ELPRO cannot provide indoor antennas e.g. by beacons.

As site owner and in order to answer questions about the site conditions, it is most efficient if the customer approaches the network provider self.

Please check whether the network is available in the respective country.

If network is available in your country, you can contact the national network provider in order to:

• check whether there are available antennas in the vicinity which can be upgraded to to LTE-M / NB-IoT
• model on the basis of the given conditions (e.g. second basement floor, masonry) whether reception is realistic when additional antennas are connected
• work out a proposal for an in-house supply system

Simply open the battery compartment on the back by hand and remove the old batteries and insert the new ones.
