SODAQ SARA is an Arduino Compatible Cellular IoT Board with LTE-M, NB-IoT, and GNSS (Crowdfunding)

There really seems to be a push for cellular IoT those days, with new hardware coming up every week.  Following up on their NB-IoT shield for Arduino last year, SODAQ has now launched two versions of SARA boards based on u-blox SARA LTE-IoT modules, and u-blox M8Q GPS/GNSS module. Both boards are Arduino compatible thanks to a Microchip SAMD21 MCU, and while u-blox SARA board follows the Arduino form factor, u-box SARA SFF is much more compact (50×25.4 mm) and potentially easier to integrate into a project or product. Another pretty unique feature (AFAICT) is that you can power the board directly with a solar panel. u-blox SARA board specifications: Wireless module (three options) with external antenna: SARA-N211 NB-IoT, band 8 and 20, for the European and African market SARA-R410M Dual mode LTE-M and NB-IoT module for all global bands SARA-R412M Triple mode module with LTE-M, NB-IoT and 2G for […]

NB-IoT Overview, Technical Presentation, and Getting Started (in Thailand)

As I mentioned in my post yesterday I attended a talk about NB-IoT at Chiang Mai Maker Party 4.0 (2017). It was presented by representatives from AIS, a large telco company in Thailand, and I’ll give a summary of what I learned beside that Xiaomi Mi A1 camera is not that good after all, and I should have taken my DSLR camera with me instead. So apologies for the poor quality of some of the photos… The talk started from a higher level, including marketing / business propositions, and has time passed it become more and more technical. The first part of talk was presented by Phuchong Charoensuk, IoT marketing specialist at AIS, and he provided some more details about the company, and their current B2B IoT/M2M market (400,000 subscribers), before providing an overview of IoT, and how NB-IoT will bring in not only larger businesses but also startups and […]

Riot Micro RM1000 NB-IoT and eMTC Baseband Chip Unveiled for the Cellular IoT Market

Telecommunication providers don’t intend to let newcomers like Sigfox or Semtech (LoRa) get all the fun and money with the Internet of Things, and that’s why LTE Cat M1 (eMTC) and Cat NB1 (NB-IoT) have been standardized. We have already covered module and silicon vendors products such as U-blox SARA-R4 / SARA-M2 modules, or Mediatek MT2625 SoC supporting the new protocols defined in 3GPP release 13 specifications. U-blox even have a module that supports both NB-IoT and eMTC in a single chip, but they are not alone anymore, as a startup called Riot Micro introduced RM1000 baseband NB-IoT & eMTC chip. RM1000 key features & specifications: MCU – ARM Cortex-M0 processor Storage – QSPI Flash interface Connectivity LTE-M Baseband supporting 3GPP Release 13 NB-IoT Baseband supporting 3GPP Release 13 SIM interface with power control Peripherals Digital data and control interface to popular RFICs (RBDP/DIQ/SPI) 3x UART interfaces General purpose I/O […]

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 […]
