Microchip Introduces $11 RN2483 & RN2903 LoRa Modules and $70 LoRa Evaluation Kits for IoT & M2M Applications

LoRa is one of those long range low power WAN standards used for the machine to machine (M2M) and Internet of things (IoT) applications. I already featured a Semtech Lora module here with a line-of-sight range of up to 20 to 30km, and the company has just partnered with STMicro to deploy LoRa solutions, but today, I’m going to have a look at Microchip Lora modules and development kits that I discovered in the company’s Micro Solutions Nov/Dec 2015 publication. The company has launched two modules for the European and North American markets with respectively RN2483 LoRa 433/868 MHz R&TTE Directive Assessed Radio Modem and RN2903 915 MHz North American modem. Apart from the different frequencies, both modules have similar features: On-board LoRaWAN Class A protocol stack Tx/Rx Power RN2483 – 40 mA (14dBm, 868MHz) Tx, and 14.2 mA Rx @ 3.6V RN2903 – 124 mA Tx max, and 13.5 mA […]

Archos Introduces Free PicoWAN IoT Gateway, Costing 75 Cents Per Year Per Connected Device

The Internet of Things is promising billions of connected devices in the next few years, and while devices at home can usually connect through your broadband connection at no extra cost, devices on the field may need to use cellular connectivity and cheap 2G network are being phased out by Telcos. Weightless, operating over white space frequencies, is one of several solutions proposed to connect IoT objects over longer distances, but Archos has their own project with PicoWAN pico-gateways using LoRa(WAN) protocol which allows for several kilometers range. PicoWAN would plug into your wall socket, connect to your broadband network over WiFI and offer connectivity to various “things” over LoRa. Creating a cellular network is expensive, due to the costs of base stations, but PicoWAN is so cheap, 100 times cheap than traditional base stations, that Archos plans to giveaway 200,000 gateways across Europe to create an IoT network. That […]

Comparison Table of Low Power WAN Standards for Industrial Applications

WiFi, Bluetooth and Zigbee are commonly found in consumer devices part of the “IoT ecosystem”, but the range, cost, power consumption, and/or scalability of these wireless standards are not suitable. For example, agricultural and forestry applications normally require long distance, and smart parking or city lighting may requires scalability to a great number of nodes, so alternatives are needed. EDN wrote a thorough article comparing 10 alternative wireless standards: Weightless-W, Weightless-N, Weightless-P, SigFox, LoRaWAN, LTE-Cat M, IEEE P802.11ah, Dash7, Ingenu RPMA, and nWave. The table includes the frequency band, channel width, range, transmit power, packet size (minimal or maximal), downlink and uplink data rates, maximum number of connected devices, topology, roaming capability, and status. If you had to implement something today, four to five solutions are “in deployment”: SigFox, Ingenu RPMA, nWave, LoRa, and possibly Dash7, while the other are only starting to get deployed, or will be finalized in […]
