All devices communicate directly with gateway
May reduce network traffic and increase communication speed
Self-healing mesh network
All devices can talk to each other and to gateways
If a device fails the signal finds an alternate path to the
gateway
Determines how devices talk to each other
Different topologies present unique pros and cons
Some topologies are more common in wired vs.
wireless systems
Luminaires, sensors and switches are connected to gateways or
directly to the server via low-voltage cables
Essentially functions as a wired local area network (LAN)

• Set of rules that define how devices communicate
• Devices designed to same protocol(s) are interoperable

Gateways ⟷ components (wired): often proprietary, sometimes DALI
Luminaire controllers ⟷ LED drivers: typically 0-10V, sometimes DALI
