Sony CXM1501GR ELTRES LPWAN Module Promises a Range of over 100 Km

While there are many LPWAN (Low Power Wide Area Network) standards, three appear to dominate the news namely LoRaWAN, SigFox, and 3GPP NB-IoT/eMTC. They all offer long range and up to 10-year of battery life enabled by the use of low bitrate which is fast enough to send sensor data. We can now add another LWPAN standard to the list, as Sony has developed ELTRES wireless communication standard suitable for IoT networks, and announced their CXM1501GR ELTRES module with a range of over 100km, even while traveling at 100km/h. Key features and specifications: ELTRES Connectivity Antenna radiated power – 20mW Communication direction – Uplink only Frequency – 923.6 MHz to 928.0 MHz (23-channel frequency hopping) Main modulation system – π/2 Shift BPSK Sub-modulation system – Linear chirp modulation Transmission system – Four repeated transmissions of 0.4 sec or shorter packets Reduction of interference with other systems – CSMA (Carrier Sense […]

Ruuvi Node Open-source Node Solution Combines Nordic Semi nRF9160 Cellular SiP & nRF52840 Bluetooth SoC

Back in 2016, we covered Ruuvi Innovations’ Ruuvitag open source Bluetooth & NFC sensor beacon is based on Nordic Semi nRF52832 Bluetooth SoC. The company has now introduced Ruuvi node, another open source multi-purpose, industrial-grade cellular gateway, environmental sensing, and asset tracking node solution based on not one, but two Nordic Semi chips with nRF91 cellular IoT SiP (System-in-Package) with NB-IoT and LTE M (eMTC) connectivity and nRF52840 multi-protocol Bluetooth 5.0 SoC. It’s an early announcement with the launch of the first pilots of Ruuvi Node planned for Q2/Q3 of this year, so the full specifications are yet to be released. However, thanks to a press release on Nordic Semi website, we do know that Ruuvi Node is meant to be maintenance-free, will include a solar panel for energy harvesting (which mean the included 45Wh battery may never run out depending on the application), several environmental sensors, GPS positioning provided […]

Sigfox Targets Worldwide Coverage with Satellite Launch

LPWAN technologies such as NB-IoT, Sigfox, and LoRa deliver low power, long range communication at low bitrate and can be used for asset tracking, environmental monitoring, water & electricity meters, and so on. The line-of-sight range between the closest gateway and nodes is usually 10 to 20 km, and coverage can be expanded by connecting several gateways to form a network. However, this is not workable in all locations worldwide, so Sigfox plans to launch a Sigfox satellite in collaboration with Eutelsat in order to provide coverage in places like large deserts such as the Sahara desert, the two poles, as well as oceans as explained by Franck Siegel, chief operating officer at Sigfox. This will for instance enable tracking and monitoring of oil platforms and vessels. The press release does not explains much except Sigfox and Eutelsat will test the first Satellite in H2 2019 before the commercial launch […]

LoDev S76S Board Combines STM32, LoRa and Arm Mbed Support (Crowdfunding)

There are already plenty of low power boards with a LoRa radio, but Ronoth offers another option with their tiny LoDev S76S LoRa development board featuring AcSip S76S SiP (system-in-package) with STMicro STM32L073 microcontroller, a Semtech SX1276 LoRa radio, and other components. While most hobbyist LoRa boards are designed to be programmed with the Arduino IDE, LoDev S76S is instead compatible with Arm Mbed. LoDev S76S board specifications: SiP – AcSip S76S system-in-package with STMicro STM32L073 Arm Cortex-M0+ microcontroller @ 48 MHz with 192 kB flash, 20 kB RAM Semtech SX1276 chip supporting global 863MHz ~ 928MHz ISM Bands RF front-end LoRa Connectivity Receiver Sensitivity – down to -146 dBm TX Power – adjustable up to +20 dBm Range – up to 15 km coverage in suburban areas and up to 5 km coverage in urban areas SMA antenna connector USB – 1x micro USB port for programming and power […]

The Things Industries Announces $69 Indoor Multi-Channel LoRaWAN Gateway

If you ever see a cheap LoRaWAN gateway, chances are that it is a single channel gateway such as Dragino LoRa gateways that can be purchased for as low as $56. Those will work for your private network, but if others people try to use your gateway, some LoRa nodes will fail to connect. So what you really need is a multi-channel gateway for instance to connect it to The Things Networks. That would be $200 (and up), thank you very much. The IoT can only succeed on a large scale if costs are low enough, so Things Industries decided to design, and has now unveiled a low cost indoor multi-channel LoRaWAN gateway. Meet The Things Indoor Gateway. The Things Indoor Gateway specifications: SoC – Espressif System ESP8266 WiSoC Wireless Connectivity 802.11 b/g/n WiFi 4 via ESP8266 + PCB antenna LoRaWAN via Semtech 1308 chipset with Support for 868 MHz […]
