Episode 8

OK, I admit it, this is going to be a bit of a geekfest but application protocols are an important topic to understand if you want to understand how IoT works. Protocols are the lifeblood of an IoT system and as we are about to find out, there are a few different types to choose from – each with their own characteristics and infrastructure requirements.

There are three layers of standardization in IoT networking: First, to get the data off the devices, a wireless (and sometimes a wired) interface is required - this is the media layer. To aggregate the data from all these devices, networking is required – this is the networking layer. Then once the devices can talk to each other, the question is what they talk to each other – this is the application layer.

Although they are often named the same, the media layer of IoT networking consists of two separate parts: the radio to transmit the data and the protocol to exchange the data with the receiver. Important for many reasons including updatability. While the hardware can be in place for long periods of time, you can expect protocols to change every few years as exemplified by the 802.15.4 standard which is currently on version m.

Episode 7

Meet IoT’s three layers of protocols… the media layer, otherwise known as the physical layer or radio, the network layer and the application layer. Important because they make up the network stack that transports data from the sensor to the cloud. Important because they are standardized.

Episode 6

In broad strokes, the software required for an IoT deployment can be grouped into four classes: embedded software for sensors and gateways, networking or the IoT platform (communication, rules and sometimes interpretation) data management & analytics and of course the IoT application.
Listen to this podcast (or read the transcript) with Zach Shelby as we discuss the first class, embedded software for sensors or more specifically sensor operating systems and the inevitable evolution of these disparate classes into an IoT software ecosystem ...




Episode 2

It takes a lot of work, behind the scenes work, to establish a successful connection between sensor and IoT Platform. While it’s possible to find off-the-shelf sensor subsystems for common use-cases, often, custom hardware and software design is needed to make the system/connected product/asset operate as desired.

Electric Imp sells product connectivity as a service to OEMs who want to connect, operate and manage their devices from the cloud. While starting in consumer IoT, particularly home automation, they have found their current sweet spot to be in industrial IoT.
Watch this video (or read the transcript) to see Bryan Kennedy explain that the true value of connected products isn’t from the connectivity but from transformation changes it can have on your entire business ...
