Power Over Ethernet (PoE)
Universal PoE compatibility standards help ensure that devices are powered efficiently and safely. To keep up with the increasing power demands of new technology, a new universal standard (IEEE 802.bt) was developed that provides up to 100 Watts of power. By solving the power demands challenge, IEEE 802.bt opens the door to a number of higher-power PoE applications including smart lighting and closed-circuit security cameras.
Bluetooth Low Energy
With its inherent power efficiency and availability in smartphones, Bluetooth® low energy technology is the premiere short-range wireless protocol for IoT. It is ideally suited for applications requiring long or constant operation with only short bursts of wireless transmission.
Zigbee is a popular low power, low data rate mesh networking protocol for home and building automation, industrial control, security, smart metering, etc. Zigbee is built on top of the IEEE 802.15.4 standard that defines the PHY and MAC layers.
Sigfox, a Low Power Wide Area (LPWA) protocol, enables the simplest and lowest cost connectivity option for IoT devices. Sigfox devices do not require any pairing operations and are ready to use right out of the box.
Proprietary RF allows system designers to customize the protocol to support their application needs. The designers can minimize on-air time to lower the power consumption to the bare minimum. Proprietary protocols allow for products to be truly differentiated in the marketplace when interoperability is not required. Another advantage is there is no forced maintenance or upgrade cycles.
Wired connectivity solutions are inherently secure and reliable. They are popular in building automation, smart meters, smart energy control, smart lighting, industrial, security, and other Internet-of-Things (IoT) applications.
Wi-Fi is the wireless networking technology based on the IEEE 802.11 standard that allows devices to connect to the internet. Wi-Fi uses the unlicensed 2.4GHz, 5GHz, and newly ratified 6GHz bands and is optimal for high speed, medium range applications. While Wi-Fi has its roots in residential and enterprise applications, it is expanding into many other applications such as IoT, automotive, outdoor, and industrial.
