This article provides a comparison between UWB (Ultra Wide Band) and Insteon technologies, highlighting their differences based on various parameters.
What is UWB?
UWB (Ultra Wide Band) technology utilizes a spectrum that exceeds 500 MHz. In 2002, the FCC authorized the use of unlicensed spectrum within the 3.1 to 10.6 GHz range for UWB applications.
It employs short-duration Electro-Magnetic (EM) pulses for rapid data transfer across a wide bandwidth (BW). UWB adheres to the IEEE 802.15.4a/z standard. Its expansive bandwidth allows for high data rate communication (approximately 27 Mbps). UWB is favored for its low latency, minimal power consumption, and robust immunity to interference.

The image above illustrates a UWB network comprising UWB anchors positioned at various locations. These anchors communicate with UWB tags, UWB smartphones, UWB lights, and a WiFi AP. The WiFi AP or router connects to the cloud via a gateway. UWB technology facilitates the collection of sensor data from motion, temperature, and light sensors. It’s suitable for precise location and tracking applications.
What is Insteon?
Insteon technology was developed by “Insteon” USA. This technology enables devices to communicate using RF, Powerline, or a combination of both. Common applications of Insteon include smart home automation and electrical control. Typical Insteon devices available on the market encompass home appliances, hubs, sensors, control switches, keypads, thermostats, and range extenders.

The figure depicts a typical Insteon network. As shown, Insteon devices do not require a router for communication; they can directly communicate in mesh mode. Key features of Insteon technology include:
- Supports dual-band (RF and Powerline) in mesh topology mode.
- Supports simulcast, enabling simultaneous addressing of hundreds of nodes without routing.
- RF packets are small: 14 bytes for standard messages and 28 bytes for extended messages.
- Powerline messages are also available in two types: standard (10 bytes) and extended (24 bytes).
- Devices are assigned a 24-bit address, supporting up to 16,777,216 devices in the network.
- The Insteon system utilizes a total of 65,536 commands.
- The Powerline physical layer employs BPSK, while the RF physical layer uses FSK modulation.
Difference between UWB and Insteon
The following table highlights the key differences between UWB and Insteon across various parameters:
| Features | UWB | Insteon |
|---|---|---|
| Data Rate | 110 Mbps | 13165 bps (Instantaneous powerline), 2880 bps (Sustained Powerline), 38.4 Kbps (Instantaneous RF) |
| Physical layer | RF | RF, Powerline, or both |
| Operating Frequency band | 3.1 to 10.6 GHz | 915 MHz (US), 131.65 KHz |
| Modulation type | BPSK, QPSK | FSK in RF PHY, BPSK in Powerline PHY |
| Range (Indoor) | 300 meters | ~90 meters unobstructed LOS using λ/2 dipole antenna |
| Security | AES Unique addressing with unique ID codes, AES-256 for message encryption | |
| Number of nodes | 8 | Unlimited (Theoretically), 1000 (Practically) |
| Network Configuration | Peer to peer, Star, Multi-hop | Full mesh |
| Energy consumption | High | Medium |

Summary
UWB excels in tracking and location determination with high accuracy via wireless links at radio frequencies, making it ideal for high data rate, low latency applications. Insteon is suited for low data rate wired/wireless monitoring and control applications, such as smart home and building automation.
