Why Is IEEE 802.3bt Necessary?

Time:2020-03-17 Source:UTEPO
In 2018, the maximum Powered Device power available is increased by IEEE 802.3bt. This represents a substantial change to the capabilities of Ethernet with standardized power. The power classification information exchanged during negotiation is extended to allow meaningful power management capability.
What will IEEE 802.3bt allow us to do?
As the newest PoE standard, IEEE 802.3bt calls for two power variants: Type 3 (60W) and Type 4 (90W). This means that you can now carry 90W of electricity over a single cable to power devices like wireless access points, thermal cameras with PTZ features, LED lighting fixtures, large display screens, etc.
Why is IEEE 802.3bt important?
This comes at the perfect time to support smart buildings and Internet of Things (IoT). To make these concepts a reality, making more power available to devices is required (along with more bandwidth to accommodate more wired and wireless devices). Without PoE, smart buildings would be more expensive to design and build. Case in point: Instead of several different, standalone networks with their own wiring, connectors and pathways, single IP networks are being used. Before PoE, systems connected to IP networks required separate data and electrical connections, as well as proximity to electrical outlets. With PoE, one single cable provides data and an electrical connection.
