I actually see this IoT term more as an bullshit bingo word than
actually important for people working on it. Just use it in marketing
and people want to be part of it.
IoT just means: Connect your embedded and constrained stuff in some way
to the internet. It doesn't necessary mean that every sensor gets an IP
address.
So, if you will so: RIOT can be both. If you want to have your private
WSN, you can do it as well as your public accessible constrained device.
It's still a complicated topic to integrate it with your existing IP
networks though.
Yes, you can use a 868 Mhz optimized antenna on 2.4 Ghz as well, but the
impedance of the antenna will be really bad on this frequency. So, you
shouldn't do it. For test purposes it should be fine though. Or are you
talking about IEEE802.15.4 on 2.4 Ghz? If you just want to switch the
protocol, but not the frequency this is completely fine.
The antennas are optimized for frequencies not for protocols. There are
a lot of good articles about antenna theory online.

Dear All,
Currently I am working on an academic paper that address Riot ( I also
published one recently.). I am trying to address Riot as either an IoT
os or WSN os. However, recently I can see that it is more shifted to
IoT.
By the way, I worked on Riot before using ESP32 and the thing is , I
addressed most of my work as Riot is an Operating System and I used
ESP32 with IEEE 802.11 antenna. However, it can be used with an IEEE
802.15.4 antenna. So, can we say that we can turn it to an WSN paradigm
using IEEE 802.15.4 antenna? Or there is more just changing the radio
hardware.
(P.S In literature, WSN and IoT OS'es definitions are really tangled
and I am trying to find the best definition to differentiate.)
