Giveaway Week – WisCellular NB-IoT & eMTC GPS Tracker

WisCellular NB-IoT Board with Antennas

Rak Wireless WisCellular is an NB-IoT & eMTC Arduino shield based on Quectel BG96 module with 2G fallback that is similar to the company’s previous-generation WisLTE board, except it is certified for the global markets. I received a beta sample last year and went through the instructions to use it with a Hologram SIM card, but sadly I never managed to make it work, and eventually learned the Hologram SIM card did not support NB-IoT in Thailand. So I would have had to buy a local SIM card, but at the time, they didn’t sell those, and the only way to get an NB-IoT SIM card was to buy a development kit. Before going ahead with the purchase, I asked about coverage in my area but never managed to get a definitive answer so I gave up. So instead of keeping it in a drawer at home, I’d better just give it to somebody else who should make better use …

LPWAN Market Update – An Interview with RAK Wireless CEO

Ken Yu, RAK Wireless CEO

CNX Software interviews Ken Yu, RAK Wireless’  founder & CEO, to learn  more about the company and the current & future state of the LPWAN (Low Power WAN) market especially with regards to NB-IoT and LoRaWAN. CNXSoft: We’ve already covered several products from RAK Wireless on CNX Software, starting with WiFi IoT boards several years ago, and more recently LPWAN products based on NB-IoT or LoRa. But for readers who may not be familiar with RAK Wireless yet, could you provide a short description of what the company does? Ken Yu: RAKwireless was founded in 2014. The core founder team consists of professionals coming from established leaders in the Networking industry as Qualcomm, H3C, etc. Because our engineers have more than 10 years of experience designing Wi-Fi solutions, this was the core of our business in the beginning. RAKwireless is working towards a vision of a connected world and In building low-power, wide-area networks for the Internet of Things, we …

Olimex Launches NB-IoT DevKit Based on Quectel BC66 Module for 19 Euros

Olimex NB-IoT Devkit BC66

There are three LPWAN standards currently dominating the space LoRaWAN, NB-IoT, and Sigfox. In a recent presentation, Olimex explains NB-IoT (aka LTE Cat NB1) offers several advantages over LoRaWAN and Sigfox which include: Higher speeds of up to 25.5 kbps (UL/DL) Single GSM base station can handle up to 100 000 NB-IoT nodes Single GSM base station can cover up to 10-100km range in rural environments, and 1 to 10km in urban settings Lasts up to 10 years on a Lithium 3V battery if less than 200 bytes are sent per day The main disadvantage they listed was operator dependence, as you rely on the operator for coverage, and anything related to connectivity. In Bulgaria in particular, they found out it was not easy to get an NB-IoT SIM card activated, and the operator may shut you off without notice. For reference here in Thailand, last time I checked I could not buy a SIM card for evaluation with my …

Nordic Thingy:91 Cellular IoT Prototyping Platform Comes with 16 Sensors

Nordic Thingy:91

Nordic Semiconductor launched the Nordic Thingy:52 back in mid-2017 in the hopes of bringing app and web developers into the hardware ecosystem as fast and easy as possible.  The Nordic Thingy:52 was a Bluetooth 5 IoT sensor development kit based on the company’s nRF52832 WiSoC. Although the Nordic Thingy:52 kit is still very much available for purchase and support always available, Nordic Semiconductor has gone further launching a new development kit called the Nordic Thingy:91 targeting cellular IoT applications. The Nordic Thingy:91 is a cellular IoT prototyping platform with support for LTE-M, NB-IoT plus GPS option. Even though IoT connectivity standards like LoRaWAN, BLE, WiFi, ZigBee, and others are very much growing and expanding, Nordic Semi is fully backing cellular technology, something that has very much been available and most likely will still keep been available, and the adoption of 5G is another testimony to that. Cellular is here, and it is not going away anytime soon. The Nordic Thingy:91 …

Icarus IoT Board Features nRF9160 GPS + NB-IoT SiP in Adafruit Feather Form Factor

The new Icarus IoT board from Actinius, uses the Nordic nRF9160 SiP, a powerful yet low power system in a package designed for use with GPS and LTE-M & NB-IoT cellular data, also found in Ruuvi node which we covered a few months ago. The board’s purpose is for mobility and ease of project tracking anywhere, and can be found in application scenarios such as fleet management and security, cargo tracking, or asset monitoring, and many more. The board has power inputs for solar panel, USB or LiPo/Li-Ion Battery, which widens the boards mobile nature, and on-site, in-the-field capability. Since the form factor follows Adafruit Feather, the Icarus board benefits of additional component options for prototyping and DIY electronics projects. The nRF9160, by Nordic Semiconductor, is a SiP (System in a Package) that carries an extensive line of embedded software and hardware. As we had reported the nRF9160 SiP low-power IoT solution consists of a global multimode LTE-M/NB IoT modem, …

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

Ruuvi Node NB-IoT Bluetooth 5 Solution

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 via nRF9160 SiP, and NFC for securely reading device IDs …
