5 IoT Wireless Technology Comparisons
After the read, you will learn about the simple results of the wireless technology comparisons,
the 5 comparisons of IoT networking technologies NB-IoT, LoRa, ZigBee, Wi-Fi, Bluetooth.
What is the Internet of Things (IoT)?
The Internet of Things (IoT) is the Internet where everything is connected. There is another way
to say it: the Internet of Everything.
What is considered an IoT product?
Let's take two examples, e.g. 1, an ordinary watch is not considered IoT because it will not be
connected to the outside world.
E.g. 2, A smartwatch, on the other hand, counts as an IoT product because it can be connected to
a mobile phone via WiFi, Bluetooth, and other technologies, exchange information, and be
controlled remotely. It can also interact with people.
By the smartwatch, we can see that the IoT has the following characteristics.
People are connected to things
Things are connected to things
Information
Remote management control
Intelligent
Networking technologies
There are many networking technologies on the market today, so we will briefly compare the
features of various networking technologies so that readers can choose the right one for their
application scenario.
Wi-Fi of the wireless technology comparisons
Wi-Fi, also known as "hotspot in action", is a trademark of the manufacturer of the Wi-Fi Alliance
for product branding and is a wireless LAN technology created from the IEEE 802.11 standard.

It was invented by a research team led by Dr. John O'Sullivan, an engineering graduate from the
University of Sydney.
For every electronic device, we buy in 2010 that contains Wi-Fi technology, the price we pay
includes a royalty to the Australian government for the use of the Wi-Fi patent.
Advantages:
Devices can access the internet
No wiring
Disadvantages:
Close proximity (50m)
High power consumption
Must have a hotspot
Bluetooth of the wireless technology comparisons
Bluetooth technology is a new wireless communication technology jointly announced in May
1998 by five of the world's leading companies - Ericsson, Nokia, Toshiba, IBM, and Intel.
Advantages:
The most significant advantages of Bluetooth technology are its radiation protection,
environmental friendliness, freedom from "wires", anti-theft and ease of use.
Disadvantages:
High power consumption
Cumbersome connection process
Low security
Close distance (50 meters)
No direct access to the internet
ZigBee of the wireless technology comparisons
Zigbee is a wireless protocol for low-speed, short-range transmission. The underlying layer is a
media access layer and physical layer using the IEEE 802.15.4 standard specification.
The main features are low speed, low power consumption, low cost, support for a large number
of online nodes, support for a variety of online topologies, low complexity, fast, reliability, and
security.
ZigBee technology is a new technology that has recently emerged and relies primarily on wireless
networks for transmission, it is capable of wireless connectivity at close range and is a wireless
network communication technology.
Advantages:
Low speed, low power consumption, low cost.
Supports a large number of nodes (up to 65,000)
Self-organizing network
Disadvantages:
No access to the Internet
Short-range (10 to 100 meters)
2G/3G/4G/5G of the wireless technology comparisons
2G/3G/4G/5G cellular networks technology is mainly used in scenarios where devices are

connected to the internet.
Suitable for single devices or small numbers of devices in unattended or remote areas where
there is no wired network broadband but data needs to be transmitted to the internet. Examples
include street-side unmanned vending machines, honeycomb lockers, etc.
However, IoT devices using 3G/4G/5G technology require the use of a SIM card and will need to
pay the operator for traffic.
Advantages:
Long-range (10km)
Internet access available
High mobility
Disadvantages:
4G/5G high cost, high power consumption
2G is about to be retired from the network
NB-IoT of the wireless technology comparisons
In response to the shortcomings of 2G/3G/4G/5G, new technology has been created, NB-IoT
Narrow Band Internet of Things (NB-IoT) can be deployed directly on GSM, UMTS, or LTE
networks to reduce deployment costs and enable smooth upgrades.
Advantages:
Long-range (10km)
Low power consumption
Internet access (can be plugged into a mobile phone card)
High mobility
Disadvantages:
High-speed development over the past few years, slowly covering the world, but no signal in
some areas
LoRa of the wireless technology comparisons
LoRa is a wireless standard for low-power local area networks.
Its most important feature is that it can travel farther than other wireless methods with the same
power consumption, achieving the unity of low power consumption and long-distance, it can
expand the distance 3-5 times than traditional wireless RF communication with the same power
consumption.
Advantages:
Long-range (2-5km in towns, 15km in suburbs)
Low power consumption (battery said to work for 10 years)
Security (AES128 encryption)
Disadvantages:
Slow speed
No internet access
