A Look at LoRaWAN and NB-IoT Power Consumption


LoRaWAN and NB-IoT are both designed for low power long range communication for the Internet of Things. We’ve previously seen both protocols have about the same 15km range in rural areas, and NB-IoT bitrate is a little higher since it can reach around 100 kbps, against 300 bps to 38.4 kbps for LoRaWAN. All LPWAN standards usually claim 10-year battery life, but it would be interesting to get some data about power consumption, and that’s exactly what AMIHO Technology has done by comparing LoRaWAN to cellular IoT (NB-IoT / eMTC) power consumption. They started by checking public information from datasheets, and compare Tx, Rx, Idle and Tx current for the three standards, and LoRaWAN is about three to five times more efficient in terms of current compared to NB-IoT, and as expected even more compared to LTE Cat-M1. They then went on to compare airtime for the different power states,  […]

1NCE to Offer a 10 Euros Plan for 10-Year of Cellular IoT Connectivity in Europe

For the Internet of Things to be successful, prices need to come down sharply, and eventually LPWAN connectivity should be possible with $1 to $2 modules, $5 to $10 development boards like we can get for WiFi today. Cellular IoT hardware is likely to be a bit more expensive – even when using NB-IoT – but hardware prices have to come down to acceptable levels, and so is connectivity. 1NCE brings us in the right direction for the latter with a SIM card selling for 10 Euros offering 10-year of 2G/3G/NB-IoT connectivity (1 Euro per year) with 500MB data included.  That’s about 140KB of data per day, which should be OK for applications like smart meters. There are no other fees, except if your device goes over the limit,  but the company has not provided any pricing details for the extra data. The service will cover 30 countries in Europe. […]

A List of Cellular IoT Development Boards

We’re starting to have a decent choice of cellular development boards, and as the number of products is getting larger having some sort of list would be useful. That’s exactly what Hologram has done. While the list is not quite exhaustive, they’ve pushed the CSV list to Github, and plans to update it. Hologram also encourages pull requests, so manufacturers may consider updating it with their own boards. The list focuses on development boards acting as cellular IoT endpoints, so you won’t find gateways, WiFi hotspots, end-user devices, and modules that needs to be soldered onto your own board. I have imported the list to WordPress to make it searchable, let people select the number of rows to display, and customize visible fields. The table is not automatically synchronized, so for the latest version always check out Github. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, […]

Nutaq PicoLTE IoT Kit Allows NB-IoT and LTE Cat M1 Devices Testing Anywhere

If you’ve been following cellular IoT news you must have read plenty of announced about NB-IoT and LTE Cat M1 (eMTC) hardware platforms bring LTE connectivity at lower power and somewhat lower cost than existing 3GPP networks. That’s all good, and you may have decided to go ahead with a commercial project, except none of the Telco are providing LTE IoT connectivity in your area just yet, or if it does, you may also want to test your device in bands not allowed/supported in your country (at a permitted power level). If that’s the case, Nutaq PicoLTE IoT Kit should help as an LTE NarrowBand & Cat M test measurement platform for IoT that can test NB-IoT and Cat-M1 devices in all frequency bands. Nutaq PICOLTE IoT kit key features: Supports M1 & NB-IoT devices Proven compatibility with M1 & NB-IoT devices from over 5 manufacturers Test multiple devices simultaneously […]

Avnet Silica NB-IoT Sensor Shield Works with mbed OS 5, STM32 Nucleo Board

If for some reasons, none of the many NB-IoT boards launched recently suit your needs, there’s yet another option with Avnet Silica NB-IoT sensor shield, that supports – despite the name – also supports LTE Cat M1 (eMTC) beside NB-IoT (LTE Cat NB1), and comes with Arduino headers, as well as a Pmod connector. The board relies on Quectel BG96 module, and can be controlled with Arm mbed OS 5 when connected to STM32 Nucleo board. NB-IoT Sensor Shield specifications: Cellular Module – Quectel BG96 LPWA Module Multi Modes: Cat.M1, Cat.NB1, EGPRS Global bands Cat M1/NB1: B1 B2 B3 B4 B5 B8 B12 B13 B18 B19 B20 B26 B28 B39 (B39 for Cat M1 only) EGPRS: 850/900/1800/1900 MHz Voice Over LTE support (M1 only) – PCM digital audio interface SIM card holder (also optional embedded SIM) Optional GNSS – GPS, GLONASS, BeiDou/Compass, Galileo, QZSS Expansion – Arduino headers, Pmod connector […]

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 […]

LTE Cat M and NB-IoT Shield for Arduino Features SIMCom SIM7000-Series Module (Crowdfunding)


We’ve already covered several NB-IoT (and/or LTE Cat M1) Arduino shields with products like RAK Wireless WisLTE, Sixfab Arduino NB-IoT shield, or AIS NB-IoT shield, which all happen to come with Quectel modules. A young self-taught engineer has decided to make his own Arduino eMTC/NB-IoT shield, but based on a SIMCom SIM7000-series module instead of a Quectel one found in the other aforementioned products. Board specifications: Cellular Module (one of the list depending on your location) SIM7000A LTE Cat M1 & NB-IoT module certified for AT&T and Verizon in the US SIM7000C Cat M1/NB-IoT module with 2G/2.5G fallback for the Chinese market SIM7000E Cat M1/NB-IoT module with 2G/2.5G fallback for the European market Note: The developer is also looking into SIM7000G module which should work globally, but the option is not available for now Micro SIM card holder GNSS – GPS/GLONASS with 2.5m accuracy supported by SIMCom modules Antenna – […]
