UPB Technology Presentation
Advance Information January, 2004
UPB is a new powerline communications standard for lighting and home control.
UPB signals travel over the existing wires in a home. No new wires are needed.
UPB is the successor to X-10 technology, which is now 30 years old.
UPB is digital technology, vs. X-10 analog.
UPB is an open standard, invented and licensed by PCS.
UPB has been used in commercial environments since 2001.
UPB has been extensively tested and researched in residential environments.
UPB is designed to work in most houses without “conditioning” (i.e. firewalls, repeaters, filters, noise blocks, couplers, etc.)
In residential testing, only 8% of homes needed a simple phase coupler.What is UPB?
UPB transmits using a pulse instead of a 120 KHz tone over existing house wiring
Pulse Position Modulation: The position of the UPB pulse in the UPB pulse zone represents digital information
Transmits 4 bits per cycle, 240 bits per second (30 bytes per second)
Typical UPB messages are 10 bytes, so about 3 messages per secondHow does UPB work?
UPB Pulse Zone
0 1 2 3
00 01 10 11
Pulse is in one of 4 positions, representing two bits per half cycle
Short, sharp pulse with high instantaneous power existing house wiring
Travels better on powerlines than long, small signal in X-10
UPB pulse has broad frequency spectrum, about4 to 40 KHz
Attenuation on powerline is lower at UPB frequencies
Less susceptible to noise than single 120 KHz frequency in X-10
Can coexist peacefully with X-10 systems, intercoms, baby monitors, speakers, etc. that communicate over powerlines.The UPB Pulse – Why it’s Better
(about 1 mS) ( < 0.1 mS)
Click switch 5 times to go into setup. LED blinks. Controller sends ID to switch.
