Power over Ethernet (PoE) is an integral part of GP’s
network platform. ANSI/BICSI 007-2017, Information
Communication Technology Design and Implementation
Practices for Intelligent Buildings and Premises covers PoE
in detail with applicable IEEE 802.3 PoE specifications
and should be followed.
Together with GP’s information technology teams,
work was done to ensure technology was applied to make
working in the new environment highly productive. From
individual work tools to the equipment used in collaborative
spaces, technology greatly improved to accommodate
streamlined connectivity and ease of use.
The conference room AV was significantly upgraded
to share content in the room, allow remote employees to
participate as if they were in the room and support video
conferencing in all meeting spaces. This was done using
a common AV interface for all room sizes (Huddle to
Training Room), so employees only had one thing to learn
in order to operate the AV. The AV equipment interfaces
with the integrated network system using a relay. This
relay is installed on the electrical circuit and communicates
with the integrated system over a sub-GHz
wireless protocol. This same relay is also used for

The AV and WAPs are connected with Cat 6A, while
the PoE lighting is connected with Cat 5e UTP that is
designed specifically for high power network applications.
Some of the features of the AV system include meeting
software for business teams and state-of-the-art wireless
presentation capability. The scale changes with room size
(Figure 6).
