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 Rx @ (2.1 to 3.6V) ASCII command interface over UART …

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 2016. All standards have a Line of Sight range of …

Weightless-P Standard is Designed for High Performance, Low Power, 2-Way Communication for IoT

Weightless was unveiled over two years ago, as a new standards for IoT leveraging “white space” spectrum, previously used by analog TV broadcasts, for free M2M / IoT communication using low power (10 years battery life) and cost-efficient hardware ($2 hardware) offering a range of 5 to 10 km. Development kits and base stations were scheduled for Q2 2014, but there’s either been some delays or they are only available to Weightless members, as you need to register to get notified once hardware becomes available. The Weightless SIG (Special Interest Group) has not stopped working on the standard as there are now three Weightless standards: Weightless-W (using White band spectrum), Weightless-N (sub-GHz spectrum), and and newly announced Weightless-P offering similar features as 3GPP carrier grade solutions, but at lower costs and lower power consumption. The key features of Weightless-P are shown below: Excellent capacity and scalability for IoT deployment FDMA+TDMA in 12.5kHz narrow band channels offer optimal capacity for uplink-dominated …
