Sony releases Communication Module compatible with ELTRES

Sony announced the upcoming release of the CXM1501GR communication module. It will be compatible with the ELTRES low-power wide area (LPWA) wireless communication standard that was developed by Sony for IoT applications.

IoT devices with this module will allow them them to connect to the ELTRES IoT Network Service, which is scheduled to begin service rollout in autumn 2019.
The product is designed for application in a range of IoT devices, aiming to develop various services with stable wireless communications over long distances while moving at high speeds. So far, most IoT systems transfer information obtained by sensors to cloud servers wirelessly. There, data is collected and processed, and the output is sent to user devices like smartphones or tablets for display. An LPWA network is a low-power wireless telecommunication technology used for transferring low-bit data across a wide area, and it is expected to see significantly growing demand for communication in IoT systems.

Sony ELTRES Module

The CXM1501GR communication module integrates a newly developed transmitter LSI that can transmit signals conforming to the protocol of the ELTRES wireless communication standard in the 920MHz band as well as a circuit for impedance matching with an externally mounted antenna. A GNSS receiver LSI is also integrated. Thies IoT sensor obtains time and position information.
The main features of the new module:

  • π/2-shift biphasic deviation modulation LSI operating on low power and producing a favorable SN ratio in narrow bandwidth communication.
  • Impedance-matching circuit for 920MHz external antenna, allowing direct connection to a general-purpose antenna and enabling custom antenna to be designed easily.
  • high-sensitivity, low-power GNSS LSI for compatibility with GPS, GLONASS, and QZSS.
  • high-frequency circuit optimized for GNSS reception enabling direct connection to antennas.
