UPB

From CT.wiki

Highly Reliable - The UPB method of communication is 100 ~ 1000 times more reliable than current X-10 technology and 10 ~100 times more reliable than CEBUS or LONWORKS powerline technologies. Reliability is defined as the percentage of transmitter/receiver pairs that correctly operate upon initial installation. The UPB test units are randomly installed in the environment typical of the target market. This market is defined as the single-family residential market in the US . This environment is defined to be the existing base of homes, without any modifications. This means that there should be no “fixing” the electrical system of the residence by adding couplers, repeaters or filtering. The first version of UPB will be over 99.9% reliable (>100 times X-10). Current X-10 is around 70%~80%.

No New Wires – 100% powerline communication, no new wires.

Higher Speed – 20 to 40 times the speed of X- 10 in terms of data transmitted. This is equivalent to over ten full commands per second. The average latency of command to action is less than .1 second.

Two Way Communications – Hardware, software and protocol design allow for two-way communication in all products.

House Separation – Multiple houses on one transformer will be separated by means of an addressing scheme allowing for at least 256 systems (houses) on each transformer. UPB system incorporates over 64,000 total address space vs 256 for conventional X-10. There will also be applicable encryption incorporated into the DLL layer and if necessary at the higher network layers.

Interaction – UPB communication can be used in the presence of all X-10, CEBus, or LonWorks compatible equipment with no interference between either UPB equipment or X-10, CEBus, or LonWorks equipment. The UPB technology uses a completely different frequency range than any of the wide-band, narrow-band, or spread spectrum technologies. The physical method of UPB communication is entirely different than the modulation-demodulation techniques of all X-10, CEBus, or LonWorks.

Peer to Peer – No central controller necessary for single point-to-point control or group (scene) control.
