Insteon vs WiFi | Difference between Insteon and WiFi

This page compares Insteon vs WiFi and mentions difference between Insteon and WiFi technologies.

What is Insteon ?

Insteon is a technology which uses existing electrical wiring for its communication using powerline frequency. In addition , it operates on RF waves. Insteon devices are designed to operate on RF, Powerline or both. It is created by SmartLabs which supports and encourage Insteon product developers. Typical Applications of Insteon are smart lighting, electrical control, sensors, electric cars for remote control of home appliances, thermostats, outlets and so on.

INSTEON network
Figure-1 : Insteon network

The figure depicts typical insteon network. Insteon devices are dual band operated and communicate in peer to peer mode due to its mesh network architecture. It does not require router unlike wifi for network setup. It requires router only when insteon devices are to be remotely controlled with the help of internet and specifically designed application (smartphone app). Insteon Hub is used to interface Insteon network and router. It is backward compatible with X10 technology. The following table mentions typical features of Insteon technology.

Features Insteon
Physical layers Powerline, i2/RF
Modulation/Frequency BPSK and 131.65 KHz (For Powerline)
FSK and 915MHz (For RF)
Message type for communication between devices Standard (10 Bytes), Extended (24 Bytes)
Message format From Address (3 bytes), To address (3 bytes), Flags (1 byte), Commands (2 bytes), User data (14 bytes, for extended message only), CRC (1 byte)
Refer Insteon Protocol Basics >> for more information.
Devices Parameters specific to Insteon Device Categories : 256, Unique IDs : 16,777,216 etc.
Security Physical device possession, Address masking and encrypted message payloads

Though Insteon has been in use since sometime for smart lighting and smart home automation, it has become popular recently due to its use in modern devices such as Google Assistant, Amazon Alexa, Tesla car and so on.

What is WiFi

WiFi is the short form of Wireless Fidelity. WiFi is wireless networking technology. The technical specifications of WiFi are mentioned in IEEE 802.11 series of standards. Based on data rate and coverage range there are different versions of WiFi viz. 802.11b, 11a, 11g, 11n, 11ac, 11ax and 11be. These standards are designated as WiFi-1 to WiFi-7 respectively.

WiFi connection can be established between client (i.e. Station) and router (i.e. Access Point or AP) and between two clients. WiFi makes it possible for more than one client devices to share same internet broadband connection. Hence everyone can access the internet using their smartphones, laptops and tablets at the same time. The consumer electronic devices such as TVs, DVDs and digital cameras are also designed to be WiFi compliant.

WiFi is very simple to install. It just requires WiFi compliant router which connects with internet broadband line such as coaxial line or fiber optic line. The multiple client devices can access the same WiFi router using RF (Radio Frequency) waves.

Features 802.11n (WiFi 4) 802.11ac (WiFi 5) 802.11ax (WiFi 6)
Frequency Bands 2.4 GHz or 5 GHz Only 5 GHz 2.4GHz, 5 GHz, 6 GHz (in WiFi 6E)
Data Rate Up to 150 Mbps (Maximum) 433 Mbps (Using 80 MHz and 1 Spatial Stream), 6.933 Gbps (Using 160 MHz and 8 Spatial Stream) 9.6 Gbps (Maximum)
Channel Size or Channel Bandwidth 20 MHz or 40 MHz 20 MHz, 40 MHz, 80+80 MHz, 160 MHz 20 MHz, 40 MHz, 80 MHz, 80+80 MHz, 160 MHz
Maximum Modulation 64 QAM 256 QAM 1024 QAM
Coverage range 70 meters (Indoor), 250 meters (Outdoor) 80 meters (Using 3 antennas) Better than WiFi-5 routers due to beamforming feature
