If I had to choose one thing that I´ve learned about IoT in this conference I´d say that we just can´t say yet how exactly IoT will hit us. There´s a huge risk that if IoT is going to hook on to our WiFi that it will implement older standards sub 802.11n. The reason for this is mainly to conserve battery life but also due to cost. Many of us working with wireless networks have been fighting devices using those older standards with great passion and now they´re about to hit us back in enormous numbers? Bringing back problems with multipath, airtime consuming low data rates etc? Sigh… so what would we like to see?
IF they´re going to be on the WiFi and we want them to work reliably they´ll need to be on the 5ghz band and they´ll need to play nice. And since I said work reliably, because that´s what I think we will want with our IoT devices, I don´t like the idea of putting them in the 2,4ghz burning pit and make them fight each other and everything else in it. Informing our customers and putting pressure on manufacturers (by purchasing the good stuff only!) we can hopefully push to at least get the options of 802.11n+ 5ghz chipsets supporting MIMO, STBC, MRC etc to improve the quality of their transmission and help them play along nicely on the 5ghz playground.
But that IF was a very big IF. Arsen puts out some data on how other protocols might be way better suited for many IoT implementations. I personally believe that we will start seeing a great mix of ways that IoT connects, some will be WiFi and some will be another protocol more suited for that particular implementation or requirement.
On the security side of the IoT theme we´re just as guessing. The feeling is that there should be a good way for mass provisioning IoT devices but there just isn´t yet. If you can think of a great way of doing this and develop something similar to an MDM for IoT, you´ll probably get rich 🙂
SDN for WiFi
Don´t we all love this fuzzy term? “SDN”. This talk examines the definitions, concepts and possibilities for an SDN WiFi. Very interesting talk!
