Nordic Semiconductor provides ultra-low power (ULP) wireless chips that can run for a long time from small power sources, like watch batteries. NORDIC the latest version of Bluetooth is Bluetooth5 by NORDIC .It represents the greatest advancements in the specification since Bluetooth 4.0 and the introduction of Bluetooth Low Energy. Errata High throughput, Long range, advertising extensions, increased broadcast capacity, improved co-existence. IEEE 802.15.4: is a standard for low data rate, low power networks. IEEE 802.15.4 defines the physical (PHY) and Medium Access Control (MAC) layers and forms the basis for numerous upper layer networking specifications including Thread, 6LowPAN, Zigbee and Wireless HART. IEEE 802.15.4 is supported by the Nordic nRF52840 multi-protocol SoC. Thread is a standards-based IPv6-based mesh networking protocol developed for simply and securely connecting products around the home to each other, to the internet and to the cloud. Cellular IoT (A low power LTE-M and NB-IoT solution for wide area network deployments). The LTE-M and NB-IoT standards are open standards created by 3GPP to allow wide deployment of IoT nodes while leveraging existing cellular infrastructure. The LTE protocols are designed for unparalleled scalability in number of nodes while maintaining good Quality of Service. Both technologies offer eDRX and PSM which are techniques for lowering the power consumption compared to traditional LTE. In eDRX, device and network agree exact times when the device will be ready to receive data.
