RFINSTEON vs. Z-Wave: A Detailed Comparison
Advertisement
This article provides a comparison between INSTEON and Z-Wave technologies, highlighting their key differences.
About Z-Wave
Z-Wave is a routed radio-based network owned by Sigma Designs, Inc. They acquired the technology from Zensys, the original developer of Z-Wave. It utilizes a Source Routing Algorithm (SRA) for message routing. This means the message source needs to know the other devices and their connectivity within the network.
Z-Wave is designed for networks with a limited number of nodes, typically around 232 maximum. Manufacturers often recommend keeping the node count between 30 and 50 for optimal performance.
Z-Wave messages have variable sizes, with a payload size of approximately 4 to 6 bytes. It operates on various frequency bands below 1GHz, depending on the country.
About INSTEON
INSTEON is a dual-mesh network, utilizing both radio and powerline communication for robust support. It doesn’t require a routing protocol for message transmission. Instead, it simulcasts messages in precise and synchronized time slots.
INSTEON vs. Z-Wave: Key Differences
The following table summarizes the differences between INSTEON and Z-Wave technologies:
| Specifications | INSTEON | Z-Wave |
|---|---|---|
| Medium type | Supports powerline and radio | Supports only radio |
| Device types | All are peer devices | Z-Wave has network controllers and slaves |
| Network Enrollment | No separate enrollment step | Part of installation procedure |
| Network topology | Full mesh, simulcasting repeaters | Routed mesh, routing tables |
| Data rate | 38400 bps (instantaneous) | 9600 bps, 40kbps, and 100kbps |
| RF modulation | FSM in ISM band | FSK (9.6 and 40 kbps), GFSK (100kbps) |
| Powerline support | Yes | No |
| Addressing | 24-bit module ID (16777216 devices) | 32-bit HomeID, 8-bit NodeID (232 devices) |
| Message length | 15 or 33 bytes | Variable in size |
| X10 standard compatibility | Yes | No |
