Episode 3 & 4 of my Youtube series about LPWAN is about antennas for LPWAN and impact on object design. The episode 4 go deeper on the way to improve radio performance by tuning and adapting antennas with matching circuit.
As usual, this series of post are summarizing in English the content of my French video on youtube.
The RF 868MHz is a public bandwidth European Low Power Networks (LPWAN) as Sigfox and LoRaWan are using for communicating.
This bandwidth is regulated by different norms like ERC-REC-70-3E in Europe and have national norms in relation. In France ARCEP 2014-1263 seems to be the last one validated in the JO on the 30th of January 2015. The following video is a second episode of my VLOG on LPWan technologies. As usual, the video is in French but this post will give you a overview in english.
Telecom Design LAN capability is a 9600bps rf 868 transmission you can use with the sigfox modem to communicate between multiple TD120x devices. One of the main use is to have multiple sensors communicating to a sigfox gateway. The communication get benefit of the nice ultra narrow band RF transceiver included in the chip.
TD LAN is based on GFSK modulation on 25kHz channels working at 9600bps.
I did really remember where but I read it could reach long distance in the best conditions, so as it could open many opportunities, I wanted to test it in real conditions to see what we could get from it.
