A Closer Look at Ingenu RPMA Alternative to LoRa or Sigfox LPWAN Standards & RPMA Development Kit

I’ve recently started to write a bit more about long range LPWAN standards for IoT applications, especially LoRa and Sigfox, as commercial networks are being launched, and relatively low cost hardware platforms are being introduced to the market. There are also other highly expected standards such as Weightless and LTE Cat M that will bring more competition to the market. Ingenu RPMA (Random Phase Multiple Access) is another available standard that’s been in deployment for a while, and based on an earlier comparison of  long range LPWAN standards, it comes with long range, supports up to 384,000 nodes per “sector”, operates in the unlicensed 2.4 GHz ISM band, and offers high combined uplink and downlink bandwidth than competitors. Ingenu recently contacted me and provided some more details and information about their technology and development kit. One of the documents includes an “independent analysis completed by ABI Research, Inc.” comparing features […]

$2 Wisol SFM10R1 & SFM10R2 Sigfox Modules and Evaluation Board

LoRa appears to be one of the most popular long range lower power WAN standards, at least based on the number of hobbyist boards coming to market, but hardware is not exactly cheap with modules such as Microchip RN2483 & RN2903 LoRa modules selling a little over $10, and development board such as LoPy normally going for at least $35. If large scale IoT is ever going to take off, prices will have to go lower, and AFAIK we are still waiting for the promised sub $2 Weightless chips. But if Elettronica In tweet is to be believed some Sigfox modules made by Korean company Wisol are selling for just $2, likely in larger quantities. WiSOL SFM10R1 is made with RCZ1 (Radio Configuration Zone 1 – ETSI – Europe), while SFM10R2 module is made for RCZ2 ((Radio Configuration Zone 2 – FCC – North America). SFM10R1 key features and specifications: […]

LX IoT Cores Are Made for IoT and Wearables with Bluetooth LE, ANT+, 2G/3G, Sigfox, LoRa, and More

LX Group, an Australian company specializing in electronics design and embedded systems, has introduced three wireless modules for IoT and wearables which they call “LX IoT Cores”, and embeds various wireless protocol such as Bluetooth LE/Ant+, 2G/3G connectivity, WiFi, Lora, Sigfox, Taggle, etc… Let’s go though the main technical specs for the three modules, one of which it itself modular (hence the max and min size) depending on your requirements. LX Cellular Core (Right) MCU – STMicro STM32F217IGH6 ARM Cortex-M3 MCU @ 120 MHz with 1MB flash, 128kB RAM Storage – 1x micro SD card reader Communication Interfaces Radios – 2G/3G,  WiFi,  BLE,  ANT+,  provision for LoRa,  Taggle,  SigFox, optional GPS via daughter board Wired – USB,  RS485, UART, SPI,  I2C, Digital IO, ADC Sensors – Ambient Luminosity, accelerometer, gyroscope, magnetometer, temperature, humidity, air pressure, microphone USB – 1x micro USB port Misc – Reset and 2x user buttons, 2x […]

SmartEverything is a Feature-Packed IoT Board with SigFox, Bluetooth LE, NFC and GPS Connectivity, Plenty of Sensors

Atmel MCU Madness is an informal competition on Twitter where people vote for their favorite development boards. We are now at the quarter finals, and beside the usual suspects such as Raspberry Pi and ESP8266 boards, I also noticed one board that I had never heard of: AXEL Elettronica’s SmartEverything based on Atmel SAM D21 Cortex M0+ and featuring SigFox, BLE, NFC, and GPS connectivity, as well as various sensors such as humidity and temperature, 9-axis motion sensor, and so on. SmartEverything board specifications: MCU – Atmel SAM D21 ARM Cortex-M0+ MCU @ 48 MHz with 256KB Flash, 32KB SRAM Connectivity SIGFOX via Telit LE51-868 S SIGFOX 868 MHz Wireless Module with 12 months of network access included Bluetooth 4.0 LE via  TDK SESUB-PAN-T2541 module based on Texas Instruments CC2541 NFC via NXP NT3H1101FHK NFC with separate antenna (included) GPS/GNSS via Telit Jupiter SE868-A GPS/GNSS module with integrated antenna. Supports […]

Comparison Table of Low Power WAN Standards for Industrial Applications

WiFi, Bluetooth and Zigbee are commonly found in consumer devices part of the “IoT ecosystem”, but the range, cost, power consumption, and/or scalability of these wireless standards are not suitable. For example, agricultural and forestry applications normally require long distance, and smart parking or city lighting may requires scalability to a great number of nodes, so alternatives are needed. EDN wrote a thorough article comparing 10 alternative wireless standards: Weightless-W, Weightless-N, Weightless-P, SigFox, LoRaWAN, LTE-Cat M, IEEE P802.11ah, Dash7, Ingenu RPMA, and nWave. The table includes the frequency band, channel width, range, transmit power, packet size (minimal or maximal), downlink and uplink data rates, maximum number of connected devices, topology, roaming capability, and status. If you had to implement something today, four to five solutions are “in deployment”: SigFox, Ingenu RPMA, nWave, LoRa, and possibly Dash7, while the other are only starting to get deployed, or will be finalized in […]
