LoRaWAN, Sigfox, Weightless, RPMA, NB-IoT, etc… There are many LPWAN (Low Power Wide Area Networks) solutions, but it’s unclear whether most/all will survive and coexist, or there will eventually be a couple of winners used by everyone. VDC Research is claiming that so far, LoRaWan assumes LPWAN leadership for IoT gateways, explaining that “LoRaWAN (LoRa) has generated considerable traction with new product launches from a number of gateway suppliers through the past 18 months”, but points to mounting competition from 3GPP standards such as NB-IoT and LTE Cat M1. Sadly, the company did not provides number in their public announcement, and those are only available in the paid report. VDC Research still released a public executive brief (free registration required), with some of the highlights including: The global market for IoT gateway hardware is forecasted to grow to more than $2.5B in 2021. While intelligent gateways generated more market revenue […]
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 […]
A Day at Chiang Mai Maker Party 4.0
The Chiang Mai Maker Party 4.0 is now taking place until December 9, and I went there today, as I was especially interested in the scheduled NB-IoT talk and workshop to find out what was the status about LPWA in Thailand. But there are many other activities planned, and if you happen to be in Chiang Main in the next few days, you may want to check out the schedule on the event page or Facebook. I’m going to go though what I’ve done today to give you a better idea about the event, or even the maker movement in Thailand. Booth and activity area should be the same over the 4 days, but the talks, open activity, and workshop will be different each day. Today, people could learn how to solder in the activity area. The even was not really big with manufacturers/sellers like ThaiEasyElec, INEX, or Gravitech closer […]
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 […]
Mediatek MT2621 Supports Dual Mode NB-IoT and GSM/GPRS for IoT, Wearables, and Industry 4.0
Mediatek introduced MT2625 ARM Cortex-M SoC supporting NB-IoT (aka LTE Cat NB1/NB2) compatible with 3GPP Release 14 last summer, and designed for global cellular IoT devices. The company has now unveiled a new NB-IoT part with Mediatek MT2621 ARM7 dual-mode IoT SoC that is capable of both NB-IoT R14 and GSM/GPRS connectivity for applications such as smart trackers, wearables, IoT security, smart metering and industrial applications. The chip would allow you to start deploying devices with GSM connectivity, and once available in your locale, switch to the more efficient NB-IoT protocol. Mediatek MT2621 specifications: Processor – Single ARM7 core @ up to 260MHz Memory – 160KB + 4MB PSRAM Internal Flash Connectivity Integrated Baseband, RF, Antenna, and Modem DSP NB-IoT ultra-low/low/mid bands defined by 3GPP Rel-14 GSM/GPRS Bluetooth 4.2 Display – LCM interface Camera – Camera interface Audio – Audio Amplifier Integrated PMU Mediatek is really light on details, but […]
MatchBox LoRaWan Gateway Review – Part 1: Unboxing and Teardown
Last spring, I wrote about MatchX.io MatchBox LoRaWAN gateway with GPS, WiFi, and Ethernet connectivity. The gateway is equipped based on a Mediatek WiFi module running Linux (OpenWrt/LEDE), Semtech chips for the LoRa part, and support up to 65,535 nodes, such as the as well as MatchStick, MatchModule, and MatchCore sensors provided by the company. I’ve just received MatchBox gateway for review, but I’m still waiting for 920-925MHz LoRa nodes as they are going through the FCC certification process, and I also have to wait for clarifications regarding local regulations. So in the meantime, I’ll check out the gateway hardware. MatchBox LoRaWAN Gateway Unboxing The gateway is shipped with a power supply, power cord, two antennas, an installation guide,… as well as three screws and pegs to wall mount the gateway and power supply, and in case you want to install the gateway on a pole, as shown below, for […]

WizziKit is a DASH7, LoRa and Sigfox Wireless Sensor & Actuator Network Kit
Over the last few years, I’ve written several article about LoRaWAN, Cellular IoT, and Sigfox based long range low power IoT solutions. DASH7 is another LPWAN (Low Power Wide Area Network) standard that operates on the same 868 and 915 MHz ISM bands as LoRa and Sigfox, but has much lower power consumption, and the cost of a shorter range up to 500 meters, instead of the 5+km associated with LoRa or SigFox. The DASH7 Alliance Protocol (D7A) is an Open Standard, and if you want more details you can download version 1.1 of the specifications on DASH7 Alliance website. I’m writing about DASH7 today thanks to an article on ST blog about Wizzilab’s Wizzikit, an evaluation kit and framework for DASH7 with a gateway, and several nodes that can also optionally support LoRaWAN and Sigfox protocols. The kit is comprised of the following items: WizziGate GW2120 Ethernet/Wifi/Dash7 gateway – based […]
