52 I ICT TODAY 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 collabo- rative spaces, technology greatly improved to accom- modate 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 commu- nicates with the integrated system over a sub-GHz wireless protocol. This same relay is also used for controlling LED lighting fixtures that are powered over line voltage (Figure 5). 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).
