Rakwireless Launches WisBlock IoT Modular System Beta Testing Program

Rakwireless has launched several IoT evaluation boards such as RAK4260 LoRaWAN EVB relying on WisBlock modules comprised of a carrier board and a module. So far, those were always sold as part of evaluation boards, but now the company is trying to expand WisBlock use as a modular system, so users can easily build their custom systems, LEGO style. The modular system is based on four different block types: WisBlock Base – A carrier board with connectors for other block types, power supply, some ports WisBlock Core – Module with a microcontroller/processor WisBlock Sensor – Modules with environmental sensors, motion sensors, ambient light sensors, or others WisBlock IO – Adds more inputs, outputs, or connectivity options including  LTE-M / NB-IoT, cellular and Wi-Fi modules, NFC reader, and interfaces for I2C, UART, ADC, and GPIO. The company is just getting started with the solution, and initially will be offering one WisBlock baseboard, an improved version of the one used with RAK4260 …

MatchX M2 Pro LPWAN Crypto-Miner Supports LoRaWAN and Cryptocurrency Mining

A few years ago, I received MatchX.io MatchBoX outdoor LoRaWAN gateway for review, and eventually tested it with RAK811 LoRa tracker once I got a node to play with, and made sure I did not break any local laws. But now the company has come up with an unusual gateway with its MatchX M2 Pro LPWAN Crypto-Miner that acts as a traditional LoRaWAN gateway, as well as a cryptocurrency miner. I’m a bit perplexed by the solution as miners are notoriously power-hungry, but let’s have a look. MatchX M2 Pro specifications: SoC – NXP i.MX 6UL (MCIMX6G2CVM05AB) single-core Arm Cortex-A7 processor @ up to 528MHz System Memory – 256MB DDR3 RAM Storage – 256MB NAND FLASH, optional SSD up to 32GB or industrial SD-Card Networking & Wireless Connectivity LoRa Radio – SX1302 chipsets, 16 frequency channels Supports EU868, US915, AS920, AS923, AU915, KR920, IN865 regions 2.4Ghz 802.11b/g/n WiFi 4 GPS via UBlox Max 7Q GNSS receiver with additional LNA 10/100 …

RAK2287 Mini PCIe LoRaWAN Concentrator Module Supports up to 500 Nodes per km2

RAK Wireless launched its first Mini PCIe LoRaWAN concentrator module in 2018 with RAK833 mPCIe card featuring Semtech SX1301 LoRa baseband chip. It was soon followed by RAK2247 mPCIe with a very similar design but some tweaks to increase its maximum transmission power and range, and improve thermals and stability with the addition of a heatsink. The company has now introduced a new version with RAK2287 Mini PCie LoRaWAN concentrator module being mostly inspired by RAK2247 module but replacing Semtech SX1301 by Semtech SX1302 LoRa transceiver that’s suppose to reduce current consumption (and heat), lower the BoM cost, and able to handle a higher amount of traffic. The new mini PCIe card also adds u-blox ZOE-M8Q GPS system-in-package to provide GNSS functionality. RAK2287 key features and specifications: LoRa Connectivity Semtech SX1302 LoRa Transceiver with 2x SX1250 Tx/Rx front-end Tx power – up to 27dBm Rx sensitivity – down to -139dBm @ SF12, BW 125 kHz LoRaWAN® 1.0.2 compatible. LoRa band coverage …

Energy Harvesting Makes Energy Autonomous NB-IoT V2 Platform Maintenance Free

LPWAN wireless protocols like LoRaWAN, Sigfox, and NB-IoT enable long-range transfers of small amounts of data at very low power for a battery life of up to 10 years. But there’s still a need to replace the battery from time to time increasing maintenance costs. HiSilicon and Nowi have partnered to design and launch the Energy Autonomous NB-IoT V2 Platform, a sensor hub that can transmit via NB-IoT without the need to change or recharge batteries manually through its energy harvesting capabilities. Energy Autonomous NB-IoT V2 Platform key features and specifications: LPWAN module – Quectel BC95 module based on HiSilicon Hi2115 NB-IoT chip Max transmissions per day Up to 3 transmissions per day in indoor conditions Up to 6 transmissions per day in outdoor conditions Power Management Nowi NH2 (MH2D02564) energy harvesting power management IC Can operate with a range of photovoltaic (multiple) cells Dimensions – 5.5 x 3.5cm The second generation Energy Autonomous NB-IoT board is said to have …

Qualcomm 212 LTE IoT Modem Supports LTE Cat NB2, Promises Higher Power Efficiency

A few years ago, Qualcomm launched Snapdragon 212 processor for smart speakers. This post has nothing to do with this, but strangely the company decided to reuse the 212 number in its new Qualcomm 212 LTE IoT modem with the claim of being the “world’s most power-efficient single-mode (NB2) chipset”. Specifically, Qualcomm 212 LTE IoT Modem is said to require less than one micro-amp (1uA) of sleep current, support ultra-low system-level cut-off voltage (as low as 2.2V) with provisions for adapting power usage according to varying source power levels. Qualcomm® 212 LTE IoT Modem key features and specifications: MCU Core – Arm Cortex M3 @ up to 204 MHz Cellular Connectivity 3GPP Rel.14 LTE capabilities: Cat-NB2 with multi-carrier NPRACH and Paging, Cat-NB2 Release Assistance Indication (RAI), Cat-NB2 with larger TBS and 2 HARQ processes Peak Speeds – DL: 127 kbps; UL: 158.5 kbps Frequency Bands (700Mhz to 2.1 GHz for global roaming) LTE low bands: B5, B68, B8, B12, B13, …

MIOTY Silicon Vendor Agnostic, Scalable LPWAN Standard to Take on LoRaWAN, NB-IoT

[April 6th update: The article was updated to reflect Fraunhofer invented the technology] There are plenty of LPWAN (Low Power Wide Area Networks) standards designed for low power, low bitrate and long-range connectivity with the most popular currently being NB-IoT and LoRaWAN. But Texas Instruments has joined other smaller companies (Fraunhofer, Ragsol, STACKFORCE, WIKA…) to form the MIOTY alliance in order to develop and promote a new LPWAN standard operating in the sub-GHz range called MIOTY. Texas Instruments explains MIOTY was born due to a lack of scalability and robustness (interferences issues) of current LPWAN solutions. But just like other similar low power WAN standards, it aims to support long-range while achieving long battery life, but MIOTY is also supposed to help IoT developers mitigate performance degradation in high-node-count networks. MIOTY works in the same license-free bands (868 MHz, 915 MHz …) as LoRa radios with no costs involved to use the radio spectrum. The solution offers a star network …
