UPB Communications Summary
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.
Affordable - The incremental cost to add two
way communications transmitting and receiving
components to a microprocessor-based application
circuit is approximately the same as the cost to add
X-10 type transmitting / receiving components. This
cost is less than $4.00 in US parts and anticipated
royalty costs.
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)
Simplicity the UPB solution uses "off the
shelf" components for transmission, receiving and
control circuits, including standard microprocessors.
No ASIC's (application specific integrated circuits)
are necessary.
