Energy Harvesting Makes Energy Autonomous NB-IoT V2 Platform Maintenance Free

LPWAN wireless protocols like LoRaWAN, Sigfox, and NB-IoT enable long-range transfers of small amounts of data at very low power for a battery life of up to 10 years. But there’s still a need to replace the battery from time to time increasing maintenance costs. HiSilicon and Nowi have partnered to design and launch the Energy Autonomous NB-IoT V2 Platform, a sensor hub that can transmit via NB-IoT without the need to change or recharge batteries manually through its energy harvesting capabilities. Energy Autonomous NB-IoT V2 Platform key features and specifications: LPWAN module – Quectel BC95 module based on HiSilicon Hi2115 NB-IoT chip Max transmissions per day Up to 3 transmissions per day in indoor conditions Up to 6 transmissions per day in outdoor conditions Power Management Nowi NH2 (MH2D02564) energy harvesting power management IC Can operate with a range of photovoltaic (multiple) cells Dimensions – 5.5 x 3.5cm The […]

Qualcomm 212 LTE IoT Modem Supports LTE Cat NB2, Promises Higher Power Efficiency

A few years ago, Qualcomm launched Snapdragon 212 processor for smart speakers. This post has nothing to do with this, but strangely the company decided to reuse the 212 number in its new Qualcomm 212 LTE IoT modem with the claim of being the “world’s most power-efficient single-mode (NB2) chipset”. Specifically, Qualcomm 212 LTE IoT Modem is said to require less than one micro-amp (1uA) of sleep current, support ultra-low system-level cut-off voltage (as low as 2.2V) with provisions for adapting power usage according to varying source power levels. Qualcomm® 212 LTE IoT Modem key features and specifications: MCU Core – Arm Cortex M3 @ up to 204 MHz Cellular Connectivity 3GPP Rel.14 LTE capabilities: Cat-NB2 with multi-carrier NPRACH and Paging, Cat-NB2 Release Assistance Indication (RAI), Cat-NB2 with larger TBS and 2 HARQ processes Peak Speeds – DL: 127 kbps; UL: 158.5 kbps Frequency Bands (700Mhz to 2.1 GHz for […]

n-Fuse SX1302 Mini PCIe LoRaWAN Concentrator Card to Sell for 100 Euros

Semtech SX1302 LoRa transceiver was announced in Q3 2019 as an updated to the company’s SX1301 LoRaWAN gateway chip with improved efficiency, lower BoM costs, and the ability to handle more traffic. At the time, the company also showcased a mini PCIe LoRaWAN concentrator card reference design pairing SX1302 with SX1250 sub-GHz RF front end, and that could be connected to a Raspberry Pi board via an interface board. n-Fuse has now come up with a commercial product adapted from the reference design with LRWCC2-MPCIE SX1302 Mini PCIe concentrator card designed for LoRaWAN gateways. n-Fuse LRWCC2-MPCIE key features and specifications: MCU – STMicro STM32 (no details provided) LoRa Connectivity Semtech SX1302 digital baseband processor with 2xSX1250 and 1xSX1261 Tx/Rx front-ends Frequency Range – 863 to 870 MHz or 915 to 928 MHz Sensitivity <= -124dBm at SF7, BW 125KHz <= -138dBm at SF12, BW 125kHz <= -125dBm at SF7, BW […]

MIOTY Silicon Vendor Agnostic, Scalable LPWAN Standard to Take on LoRaWAN, NB-IoT

[April 6th update: The article was updated to reflect Fraunhofer invented the technology] There are plenty of LPWAN (Low Power Wide Area Networks) standards designed for low power, low bitrate and long-range connectivity with the most popular currently being NB-IoT and LoRaWAN. But Texas Instruments has joined other smaller companies (Fraunhofer, Ragsol, STACKFORCE, WIKA…) to form the MIOTY alliance in order to develop and promote a new LPWAN standard operating in the sub-GHz range called MIOTY. Texas Instruments explains MIOTY was born due to a lack of scalability and robustness (interferences issues) of current LPWAN solutions. But just like other similar low power WAN standards, it aims to support long-range while achieving long battery life, but MIOTY is also supposed to help IoT developers mitigate performance degradation in high-node-count networks. MIOTY works in the same license-free bands (868 MHz, 915 MHz …) as LoRa radios with no costs involved to […]

Meshtastic Mesh Networking Project Combines ESP32, LoRa and GPS Radio

Meshtastic is a project using off-the-shelf, inexpensive ESP32-based hardware with GPS & LoRa connectivity to create mesh networks helping hikers. skiers, paragliders, or people exercising other outdoor activities communicate short messages such as their GPS location. This allows each member of a private mesh network to see the location and distance of all other members and read/or any text messages sent to a group chat. No phone is required unless you have an ESP32 LoRa board without GPS in which case it would get the GPS coordinates from your phone over Bluetooth. A phone is also needed to send a message. The project currently works on three different boards TTGO T-Beam, TTGO LORA32 and Heltec LoRa 32. The T-Beam is recommended as it sells for around $26 plus shipping and features a 18650 battery holder so you can source the battery easily locally. Just make sure to purchase the right […]

The Things Industries Launches Global Join Server for Secure LoRaWAN

Co-Founder and CEO of The Things Industries Wienke Giezeman announced the launch of Global Join Server (GJS) which is a secure component of the LoRaWan server. As an ecosystem, Global Join Server allows activating devices of any LoRa network from anywhere on the World. According to Giezeman, it works with the Things Network, the Community Network, cloud hosting solutions, etc. It works no matter if it is a part of a network server outside the Things Industries, as long it uses LoRa standard interfaces. The Global Join Server’s role is to store root keys, generate session keys and send them securely to the Network Server and Application Server. There is no more need to send keys by email or to print them on the boxes, they are already in a secure place. The Things Industries offers to device makers, module makers and distributors, access to a network-agnostic Join Server of […]
