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 second generation Energy Autonomous NB-IoT board is said to have …

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 global roaming) LTE low bands: B5, B68, B8, B12, B13, …

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 …

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 …
