Comparison Table of Low Power WAN Standards for Industrial Applications

September 21st, 2015 Leave a comment Go to comments

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 at least 1km, with RPMA claiming up to 500km… Many standards are quite scalable as they support up to 1 millions node or more, but RPMA, and especially LTE Cat-M and P802.11ah are much less suited to projects with a large number of sensor nodes. Typical power consumption and an estimate of costs would have been two nice extra rows to have in that table, but number for these two are probably hard to come by, especially since each project is different.

If you are interested in these long range low power wide area network wireless standards, I recommend you read the complete article on EDN for much more details.

    You better update the table with adding WAVIoT LPWAN.

    The table contains faults. Weightless P is not limited to 17 dBm. In EU at 868 MHz is to limited to 14 dBm. On 870 to 875 it is allowed with up to 27 dBm. On 169 MHz it is allowed up to 27 dBm as well. On 470 MHz even higher. There are further bugs.

    I can show you 1000 km on 868 MHz. BTW, move to the beach and look to the horizon. It is estimated 4,5 km far away. 500 km is not realistic, because our nice green plant is a round ball and not a plate.
