This is the first part of the\u00a0blog series “Communication protocols in IoT” by Erik Dahlgren.<\/em><\/p>\n

Introduction<\/h2>\n

With an ever-growing buzz about IoT and new connected products constantly introduced to the market, it can sometimes be difficult to get a clear overview and understanding of all the underlying wireless connectivity technologies that enable these products and use cases. When is it suitable to use Bluetooth vs NB-IoT? What properties does Zigbee provide for a product? How is Thread different from Wi-Fi?\u00a0\u00a0<\/span><\/p>\n

In a series of blog posts, we will explain each communication protocol in a simple way and provide some insight into how and where these technologies are used in the industry today.\u00a0<\/span><\/p>\n

Coverage areas and included protocols\u00a0<\/strong><\/h2>\n

To provide some logical grouping of protocols\/networks, it’s very common to divide them into groups describing their coverage or operating area. If you have ever taken a course in Networking\/Communication, the expressions below should be familiar (Although the definitions can vary a bit):\u00a0<\/span><\/p>\n

PAN <\/b>(Personal Area Network): Very close proximity. Typically, a few square meters.\u00a0<\/span><\/p>\n

LAN<\/b> (Local Area Network): Historically a few hundreds of meters, it might also be suitable to think in terms of “sites”. E.g. your office or home most likely have one (or more) LAN:s.\u00a0<\/span><\/p>\n

MAN<\/b> (Metropolitan Area Network): Covering tens of kilometers, e.g. a city or metropolitan area.\u00a0<\/span><\/p>\n

WAN<\/b>: (Wide Area Network): Covering large distances, from kilometers out to space…\u00a0<\/span><\/p>\n

As mentioned above, the definitions might vary quite a bit for several reason when we try to assign a technology into one of the categories above. Should LTE be considered MAN or WAN? And what about Bluetooth which has typically been a school book example of PAN? With the introduction of Bluetooth Mesh, we can today easily cover a whole building with the technology. To simplify and limit our scope to technologies that are interesting in an IoT-context, we will cover these groups, definitions, and technologies:\u00a0<\/span><\/p>\n

WPAN (Wireless Personal Area Network)<\/b>
\n-NFC (Near Field Communication)<\/p>\n

WLAN (Wireless Local Area Network, not to be confused with “<\/b>WiFi<\/b>“)<\/b>
\n-Bluetooth
\n-WiFi
\n-Zigbee
\n-Z-Wave
\n-Thread<\/p>\n

LPWAN (Low-Power Wide Area Networks)<\/b>
\n-LoRa
\n-Sigfox
\n-NB-IoT
\n-LTE cat M1<\/p>\n

Hope you enjoyed this introduction of my blog series\u00a0” Communication Protocol in IoT”. Next time I will talk about NFC or “Near Field Communication” that is a wireless technology which is used for communication over extremely small distances.<\/p>\n
