u-Blox Unveils SARA-R4 LTE Cat M1 and SARA-N2 NB-IoT Modules for Professional IoT Applications

While I’ve mostly read about SigFox and LoraWan solutions for long range, low power, and low bitrate communications for the Internet of Things so far, there are many active of planned LPWAN standards for IoT applications, and 3GPP Release 13 standard stipulates two LTE LPWAN standards, namely LTE Cat M1 (eMTC) and LTE Cat NB1 (NB-IoT), with the former  supporting 1 Mbps downlink and uplink peak data rates, and the latter 250 Kbps downlink, and 250 Kbps (multi-tone) or 20 Kbps (single tone) uplink data rates. U-Blox has released modules for both standard with SARA-R4 LTE Cat M1  and SATA-N2 NB-IoT modules. SARA-N2 Cat NB1 cellular module specifications: LPWAN Connectivity – 3GPP Release 13 NB1; NB-IoT bands: 5, 8, 20; downlink: 227 Kbps, uplink: 21 Kbps Positioning – GNSS via Modem Interfaces – 1x UART, 1x SPI, 2x GPIO, 1x DDC(I2C) for GNSS Features – Antenna supervisor, embedded IPv4 & […]

Dragino LoRa/GPS HAT Board for Raspberry Pi Sells for $32

There are several ways to play with LoRaWAN protocol on the Raspberry Pi including RisingHF Discovery kit or Cooking Hacks LoRa Shield for Raspberry Pi, but the latter requires you to spend close to $100 just for the shield, the complete Lora discovery kit costs close to $400. Dragino Tech LoRa/GPS HAT board should be a more cost effective way to get started with LoRa on Raspberry Pi, as it sells for $32 + shipping on Tindie.

RisingHF IoT Discovery is a LoRaWAN Evaluation Kit for Raspberry Pi

There are many current and upcoming long range low power wireless protocols for the IoT, but this morning I learned that South Korea launched a LoRa network (aka LoRaWAN), after another launch in the Netherlands earlier this year. While there are also some LoRa hobbyist kits such as LoraONE and LoPy being worked on, I decided to look on Aliexpress, but only got two products were listed: a LoRaWAN temperature and humidity sensor, and a LoraWAN USB modem. Both of them are made by a company called RisingHF. Among the products offered by the company, there’s a potentially interesting development kit called RisingHF IoT Discovery with the following components: 1x Raspberry Pi board 1x RHF0M301 LoRa Gateway based on Semtech SX1301 1x RHF4T002  adapter for Raspberry Pi and RHF0M301 1x RHF3M076 LoRaWAN USB AT Modem End point to connect to computer. It operates at 434MHz, 470MHz,868MHz, and 915MHz 3x RHF76-052 […]

WAVIoT LPWAN Technology Powers Low Cost Smart Water and Electricity Meters

With the rise of IoT and M2M applications, more and more Low Power Wide Area Network (LPWAN) standards have been launched or being worked on, such as Sigfox, LoRa, 802.11ah “Hallow”, Weightless, etc… with all promising long range, low power consumption, and support for a high number of nodes. WAVIoT, a US startup founded in 2011, has decided to create its own solution called WAVIoT Nb-Fi (Narrowband Fidelity) that works in ISM bands, offers up to 50km line-of-sight range, supports up to 2 million nodes by gateway, lasts over 20 years on a small battery, and with WAVIoT said to cost as low as $2 per node. The technology is already available in smart electricity and water meters, and modules as shown in the picture below. Here are some of WAVIoT Nb-Fi technical specifications: DBPSK on physical layer of signal transmission; End-nodes transmit radio signal in 10-500 kHz bandwidth Minimum […]

Wi-Fi HaLow is the Consumer Name for 802.11ah Low Power Long Range WiFi

For some reasons, people who decide to name things like to give one name for technical people, and another for consumers. A few years ago, I went to buy a 1080p TV, but at first the seller was confused when I asked, and then I talked about resolution, and when he asked “Full HD” or “HD Ready”? It was my turn to me confused. There are several other example such as Bluetooth Low Energy for geeks may be Bluetooth Smart for consumers, and now the Wi-Fi alliance has just announced that IoT devices and gateway featuring the latest 802.11ah standard will be designed as Wi-Fi HaLow devices. They have not come up with a Wi-Fi Halow logo yet… Nevertheless, apart from the name, nothing appears to have changed. HaLow/802.11ah is still the same Wi-FI standard operating at 900MHz targeting IoT applications with low power, long range (up to 1km), and […]
