An ubiquitous computation environment has as
presupposed that the computation is in all equipment
and devices, and these are interacting between itself
and with the people. The connection between objects
and human beings is instantaneous, when these enter
in the ubiquitous environment. A communication
protocol to make the linking between many devices,
of many manufacturers, in this environment, will be
the key so that this connectivity happens. In the
industrial automation, the protocol RS 485, is very
used. Although some similarities in the intentions,
the residential automation has different concepts
from the industrial. The protocol I2C, of the wire
technology, developed by Philips, appears as option
for the residential automation. Protocols of wireless
technology, as bluetooth and zigbee, because of its
characteristic of covering, are presented as
complement for this automation. This article aims to
present a vision about the necessary characteristics
of the communication protocols for a ubiquitous
computation environment in the residential
automation. In it will be described the studies,
development and implantation of devices of
residential automation that occurs in the QualiHouse
Residential Automation, incubated company in the
Trilha, pre-incubator of the Faculdade Integrada do
Recife - FIR.
