M3C concentrators

The APKAPPA M3C concentrators enable the exchange of information between devices distributed over the territory and a processing center, exploiting different types of networks such as public wireless, powerline communication (PLC) and short-range networks.

Concentrators details

They are widely used in smart metering systems to allow, in an automated way, the recovery and storage of information produced by energy, gas, water meters as well as their transfer to a processing center, through the available network and, at the same time, to send commands imposed by the control center to the counters. In fact, the M3C concentrators are able to communicate

  • on conveyed waves (PowerLineCommunication, PLC), typically when they need to dialogue with the devices distributed over the territory
  • on wireless networks with TCP / IP protocol (GSM, GPRS, PSTN, …), usually when they must communicate with the back-office systems of the control centers.

M3C meters are based on ST processors of the SPEAr © line; APKAPPA, with its brand, has established a technical collaboration on their SPEAr © product to be able to integrate it in its latest generation data communication concentrators. For this, ST has granted the APKAPPA R & D team to become part of the development center on its SPEAr © wireless CPU project.

As regards to the firmware, M3C counters use the Linux operating system and can be updated with local or remote interventions.

M2M communication devices

M2M communication

To Utilities that deal with electricity distribution, APKAPPA offers its communication devices of the APYLink family, which can connect meters with a control room via public and/or satellite wireless networks. APYLink devices collect information on the operating status of the meter/control point, send it to the control room and are able to transfer instructions received from the control room to the meter/control point.

The DM550 product series is the latest evolution of the APYlink family of communication devices that takes advantage of the previous DM530, already well-known for their reliability and for being designed for complex applications. To date, hundreds of thousands of these modems are employed in smart metering solution with a perfectly working connection, in Italy and abroad.


The advantageous technology of these products is mainly summarized in:

  • Quad band communication
  • more functions, thanks to the ARM9 processor: the complete firmware application is incorporated into the engine
  • Selective Download Over The Air (DOTA). This means that it is not always necessary to download all the firmware: only its modified part can be replaced
  • Filter and security for data calls
  • Built-in TCP / IP
  • SMNP maintenance protocol and integrated telnet
  • greater reliability and temperature range
  • ready INSIM (optional)
  • full technical compatibility with communication modules of the previous series. This means that you can replace the “At420” model with the new DM530 without modifying anything of your system.
  • complete with removable omnidirectional antenna, cables and installation accessories
  • operating temperature range: -35 ° C to + 75 ° C (relative humidity <90%)
  • casing certified in protection class IP54
  • casing with self-extinguishing material UL94 certified

Certified quality:

  • 10 years of expected life
  • failure rate better than 0.35% per year
  • MTBF> 450,000 h (@ 20 ° C)
  • FIT <2000 (@ 20 ° C)
  • complete with Remote Device Management Services (RDMS) for maintenance actions


In addition, the DM530 takes advantage of the experience gained by in the design and construction of similar equipment for the largest Italian energy distributors, where the reliability and the cost-effectiveness of its solution is today the most appreciated.


CM, the plug-in modem for MSC and LVM concentrators

The CM wireless modems, in the 40 and 60 versions, are used for the remote reading of electric meters.

They are born as accessories of MSC and LVM concentrators and perform the function of data communication on 3G and 4G network without requiring connections to other external modems.

They are easily installed by interlocking (i.e. plug-in) in the concentrator, thus also avoiding the use and installation of additional cables.

Robust and reliable, it is equipped with procedures that always keep it always-on.

Thanks to the CM modems, with a simple gesture the concentrator is enabled to communicate data on the GSM / GPRS / UMTS networks to one or more control centers: just add the SIM card.

The 4G router to communicate data on broadband network in smart metering systems and smart city

APR410 is a device designed to allow wireless data communication over the broadband network and to be installed in secondary substations of the electricity distribution network.

The 4G APR410 router is the ideal device for remote management, remote control and smart city systems because it performs the tasks of collecting and transmitting data detected by sensors spread over the territory with maximum efficiency and the use of open and standard technologies.

It has been designed to ensure minimum bulk and maximum compactness so that it can be easily adapted to environments that are less hospitable both in terms of space and environmental condition.


It is a powerful, programmable and high-performance industrial device that allows 4G wireless connectivity with fallback on 2G and 3G networks and the application of multiple strategies to ensure the "Always On" status, including routing / switching.

It offers a high level of immunity from electromagnetic disturbances and, in general, applies safety strategies anywhere: from the use of signed "packages" to allow software remote updating up to local management and maintenance via Ethernet port with protected access and remote maintenance through protected SSH sessions with authentication and encryption.

It also offers the possibility of connecting other devices thanks to its Fast Ethernet interfaces.

It is simple to install, boasts mechanical strength and a compact design with reduced dimensions; it does not include moving parts (eg cooling fans), it guarantees high reliability also in terms of duration and resistance in harsh operating environments and at low consumption.

This is the ideal router for the  smart city!
