Semtech SX1302 LoRa Transceiver to Deliver Cheaper, More Efficient Gateways

SX1302 Raspberry Pi Gateway

After our interview with Rak Wireless CEO, we received a comment inquiring about the availability of SX1302 gateways. Semtech so far had two LoRa transceivers for gateways namely SX1301 and SX1308, but I had never heard about a third one. Semtech SX1302 is brand new, the latest generation of baseband LoRa chip for gateways that is said to reduce current consumption in order to simplify the thermal design of gateways, as well as the BoM (bill of materials) costs), while being capable of handling a higher amount of traffic. Semtech SX1302 LoRa Transceiver Key features: Up to -141 dBm sensitivity with SX1250 Tx/Rx front-end 125 kHz LoRa reception with: 8 x 8 channels LoRa packet detectors 8 x SF5-SF12 LoRa demodulators 8 x SF5-SF10 LoRa demodulators 125 /250 / 500 kHz LoRa demodulator (G)FSK demodulator Direct interface to Semtech transceivers SX1255, SX1257 and SX1250 SPI host interface Single 32 MHz clock QFN68 Package Temperature Range – -40°C to +85°C.

Semtech Releases Open Source Software for LoRa Gateways & Devices

Lora Basic Station

Semtech has released open source software for LoRa-based gateways including LoRa Basic Station packet forwarder for Linux-based gateways, LoRa Basic MAC implementation of the LoRa Alliance’s LoRaWAN specification, and LoRa Basic loader bootloader capable of handling firmware updates. All three components are available for free under a revised 3-Clause BSD license. LoRa Basic Station supports LoRaWAN Classes A, B, and C, presents a unified radio abstraction layer supporting Concentrator Reference Designs v1.5 and v2, and implements various backend protocols. Apart from mbedTLS and libloragw/-v2, it does not rely on external dependencies, the code is written in C language only, and easily portable to Linux gateways and embedded systems. LoRa Basic MAC is a fork of IBM’s LMiC library, also implemented in C language,  supports multiple regions selectable at compile and/or run time, and can handle Class A, Class B, and Class C devices. Basic MAC uses LoRa Basic loader to load its firmware, and to support firmware updates over-the-air (FOTA). …

Semtech SX1261/SX1262 LoRa Development Kit Now Available for $305

SX1261 Evaluation Board

Semtech announced SX1261, SX1262 and SX1268 LoRa chips in January as updates to their current LoRa solutions with a lower footprint, better efficiency, and even longer range. Mass production and development kits were expected in March 2018, and today I found out Semtech SX1261/SX1262 development kit is sold on Mouser for $305. The SX126xDVK1CAS kit comes with the following items: 2x SX126xMB1xAS RF modules including an  ST Nucleo Mbed board and a touchscreen 2x Mini-USB / USB connection cables 2x 868/915MHz antennas 2x Mini-USB cables 2x touchscreen styluses Read-Me Note The SX1261/SX1262 LoRa Transceivers offer continuous frequency coverage from 150MHz to 960MHz. You’ll find information to get started in the user guide. Basically, the two boards will show a menu on the touchscreen with radio test modes, settings and utilities (e.g. firmware update) as well as two demos: DEMO Ping Pong performs a bidirectional range test between the two radio units. DEMO PER performs a unidirectional packet error rate test …

Semtech Improves LoRa Efficiency and Range, Reduces Footprint with SX1261, SX1262, and SX1268 LoRa Chips

LoRa is one of the most popular LPWAN technology deployed around the world with chips made by Semtech, as it allow long range, low power communication at low bitrate, and is especially useful for asset tracking, smart parking, and all sort of remote monitoring of persons (e.g. elderly fall for seniors) or assets (e.g. leak detection). Depending on your applications, i.e. data size and update frequency, a coin cell battery can last up to 10 years The company has now introduced the second generation LoRa technology with three new RF chips that are 45% smaller, reduce power consumption by 50% (4.5 mA) , and extend range by 20%. The new chips also offers a high-power transmit option (+22 dBm), supports FSK modulation for migration to LoRaWAN from legacy protocols, and includes a new spreading factor for dense networks. Full list of new features listed by the company: 50% less power in receive mode 20% more extended range +22 dBm transmit …

433/868/915 MHz LoRa Modules Are Now Selling for $6 and Up

Market forecasts for the Internet of Things promise billions of connected device in the years to come, but this won’t happen when LPWAN  connector sensors cost $50 or more, so prices will have to come down. I’ve been told that one company is working on a WiFi + LoRa module that’s going to sell for $5 to $6 sometimes in 2017, but in the meantime, it’s possible to get some LoRa modules for less than $10, albeit limited to 433 MHz frequency not the more common 868 MHz (EU) and 915 MHz (US), thanks to products such as AI-Thinker Ra-02 module. Ra-02 specifications: Chipset – Semtech SX1278 low power long range transceiver Radio 433MHz frequency (420 to 450 MHz range) +20dBm – 10mW constant RF output vs. V supply; up to 300 kbps bitrate Supports FSK, GFSK, MSK, GMSK, LoRa and OOK Modulation Mode 127dB RSSI wave range.

Semtech LoRa SX1272 RF Module Enables Up to 30 KM Wireless Range for Arduino, Raspberry Pi, Waspmote, and More

Libelium’s Waspmote is a board based on Atmel ATmega1281 MCU that interfaces with over 80 sensors, and various wireless communication modules, and targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on. They have some professional kits for over 3,000 Euros including training, but a more affordable Starter Kit is also available for 199 Euros on Cooking Hacks. But I’m not going to cover Waspmote in details today. I just mention it because of an article on embedded.com mentioning compatibility with a Libelium / Semtech LoRa SX1272 RF module delivering up to 30km range in ideal conditions (and usually 22+ km range in LOS), and about 2km range in urban settings. I previously featured XBee-PRO 900HP RF Module with a 45km range, so the Semtech module is just another option, and it works not only with Waspmote, but also the Raspberry Pi, Arduino, and Intel Galileo boards. and possibly as …
