IoT connectivity options
In the previous section, we covered lots of concepts about networking, wireless technologies, and different IoT connectivity needs, which were needed to understand the different IoT connectivity options we will mention in this section. We will not go into the low-level details of such technologies, but rather, will give a high-level overview of them.
We can classify connectivity broadly into two categories: wired and wireless connectivity. For wired connectivity, we have the options outlined next.
Classic Ethernet (IEEE 802.3)
The Ethernet protocol is a well-known and widely adapted internet protocol used in transmitting data at high speed on the LAN. This protocol covers the physical and data link layer of the OSI model. There are different kinds of Ethernet standards, and new standards provide data transfer at a rate of 10 Gbps.
The physical layer consists of cabling and devices; there are different Ethernet cables such as coaxial cables (a bit...
