FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -4 is a technical standard which defines the operation of a low-rate wireless personal area network (LR-WPAN). It specifies the physical layer and media access control for LR-WPANs, and is maintained by the IEEE 802.15 working group, which defined the standard in 2003.

Detailed explanation-2: -IEEE 802.15 is the working group for WSNs, or wireless specialty networks, such as wireless personal area networks (WPANs), Bluetooth, Internet of Things networks, mesh networks, body area networks, wearables, visible light communications, among others.

Detailed explanation-3: -The IEEE P802. 15 Working Group for WPANs will develop Wireless Personal Area Network standards for short-range wireless networks. The Working Group is cog-nizant of emerging industry specifications, viz., BluetoothTM, HomeRFTM, etc.

Detailed explanation-4: -IEEE 802 is a collection of networking standards that cover the physical and data-link layer specifications for technologies such as Ethernet and wireless. These specifications apply to local area networks (LAN) and metropolitan area networks (MAN).

Detailed explanation-5: -The IEEE 802.15. 4 standard specifies the MAC and PHY layers of Low-Rate Wireless Personal Area Networks (LR-WPANs) [1]. The IEEE 802.15. 4 MAC and PHY layers provide the basis of other higher-layer standards, such as ZigBee, WirelessHart®, 6LoWPAN and MiWi.
