MTX-3G-JAVA device receives AT&T approval

The powerful MTX-3G-JAVA device has recently received approval from the US network operator AT&T.AT&T Certified

Based on new EHS6 Java possibilities such as MIDlet parallel execution, FOTAP, greater memory and higher speeds, MTX-3G-JAVA can be used in many M2M and IoT scenarios and applications. It is Java programmable and flexible according to your requirements. Its variable characteristics include GPS/GNSS, an internal Ion-Li 1650mA/h battery, an Ultra Low Power mode, and an RS485 BUS interface and with an RF card inside (Bluetooth, ISM, Wi-Fi, W-MBUS).

MTX-GATEWAY device receives PTCRB approval

The powerful MTX-GATEWAY device has recently received approval from the CTIA PTCRB certification body, tested by the 7Layers laboratory in Germany, as well as from the US network operator AT&T.

An innovative gateway with unlimited power, this modem is a compact yet powerful terminal, containing a complete set of wired and wireless interfaces and powered by an ARM9 processor module with embedded Linux and JAVA VM.

ThiPTCRBs modem can be used in infinite M2M and IoT applications thanks to the fact that it contains plenty of powerful interfaces including Ethernet, Wi-Fi, 2G-3G-4G connectivity, USB OTG, RS232/RS485/RS422, CAN, and GPIOs, as well as the following optional add-ons: Bluetooth LE, Zigbee and GPS/GLONASS and Wi-Fi (B/G/N). It embeds an industrial Freescale i.MX28 (TQMa28) module (ARM9@454MHz, RAM@128MB, FLASH@4GB, EEPROM@32KB) and an internal mini-PCIe slot which can accommodate any communication board you need: LTE & GPS, HSPA+ & GPS, GPS, Wi-Fi, Bluetooth 2.1 or Bluetooth Low Energy. It is manufactured following the ISO-9001 and ISO-14001 Quality certifications, and is RoHS and WEEE complaint.

This approval shows that the device is complaint with the cellular network standards, meaning it cannot be blocked from networks and guaranteeing functionality.

Discover our new M2M-IoT solutions at SPS IPC-Drives exhibition, Nuremberg Nov 25-27th 2014. Pabillion 10, Stand 639

MTXM2M exhibirá en SPS IPC Drives Nuremberg Nov-25-27We invite you to our demostrations and presentations of latests MTXM2M products at SPS IPC-Drives exhibition. Our portofolio has been increased from our Java embedded programmability modems to our new Linux core MTX-Gateway which gives unlimited possibles M2M scenarios like remote control, telemetry, mesh network, fleet management, metering and many others. We’ve added radio frecuency cards -Bluetooth, Wifi, Zigbee, WMbus, GPS/GSNSS-  but also wired CAN, USB OTG, 1 wire or RS232/RS485 Mbus ports to connect and control any external devices without anything else.

Please meet our MTXM2M engineer and sales to realize your IoT application is easy and possible.

We will be present at

Example 2. Reading of an electric and PLC meter via GSM and GPRS using a double gateway

Details of the example scenario:

  • The current scenario has a modem with two series ports. One is connected to an electric meter and the other to a PLC.
  • When there is no GPRS connection in the modem, nor a GSM call established by the operator, the modem must act as a Series-Series gateway; that is, all the data that arrives to the modem from the PLC must be redirected to the electric meter and vice versa.
  • There must exist the possibility of setting up two GPRS-Series Gateways working in parallel. One will provide access to the electric meter to carry out regular readings, whilst the other must be able to allow access to the Modbus records in the PLC.
  • Additionally, the energy provider (Endesa, Iberdrola, etc.) will make a daily GSM call to carry out a reading of the meter. This call must take priority, freezing all GPRS connections until it has ended.

Proposed solutions with MTX-65i and MTX-Tunnel

  1. When there is no GPRS connection from the office, to the modem, or the PLC and there is no established GSM call from the energy provider, the modem acts as a transparent Series-Series gateway; that is, resending the data from the PLC directly to the meter and vice versa.
  2. When a GPRS connection is made with the modem, the Series-Series gateway between the PLC and the meter is interrupted and gives way to the transparent GPRS-RS232 gateway between the office and the meter in order to be able to read the meter.
  3. If you require so, two simultaneous GPRS-RS232/485 gateways can be made from the office to the devices – one to access the meter and the other to access the PLC – by taking advantage of the two series ports that the MTX-65i has. Obviously, the Series-Series gateway between the PLC and the meter remains interrupted.
  4. When we have two simultaneous GPRS-RS232/485 gateways, a GSM call from the energy provider can still gain access, and the MTX-Tunnel will be able to manage it. In this case, the GPRS-RS232/485 gateways are frozen, giving priority to the GSM call from the provider.
  5. Once the call from the energy provider to read the meter is finished, the GPRS-RS232/485 gateways that were previously established from the office, be it to read the meter in real time, to access the PLC, or both, are reestablished.
  6. Then, once again, when there are no GSM calls or established GPRS connections to access the meter or the PLC, MTX-Tunnel restores the transparent Series-Series gateways between the PLC and the electric meter.
