Wireless Wide Area Network: A wireless wide area network (WWAN) is a specific type of network that sends wireless signals beyond a single building or property. By contrast, a local area network or LAN connects computers and other hardware pieces inside a residential or commercial property. Wireless wide area networks and wireless local area How widespread the network is can be defined as a Personal Area Network (PAN), such as Bluetooth connections, a Local Area Network that would be in a local area like an office building, or, a Wide Several wireless personal area networks (WPAN) are described in this chapter. Bluetooth consists of two versions—basic rate/enhanced data rate (BR/EDR), and Bluetooth low energy (BLE). BR/EDR is used mostly for streaming data applications whereas BLE serves control and monitoring functions as well as one-way beacons, where very low energy Example 1: Wireless Local Area Network. In this LAN example, a typical local area network is shown consisting of a server, router, access points, and mobile clients. However, unlike traditional LANs, mobile clients are not connected to the access points via physical wires or cables. Rather, each of the mobile clients is connected to its Those groups set the standards for common types of wireless technologies used for personal area networks. Those 802.15 task groups include: WPAN/Bluetooth, Coexistence, High Rate WPAN, Low Rate WPAN, mesh Networking, Body Area Networks, and Visible Light Communication. Each IEEE protocol has its own distinctive advantages and limitations. Bluetooth LE is an ultra-low-energy network in the 2.4 GHz band that connects devices in a short range. Bluetooth Low Energy or Bluetooth LE is a connectivity technology that enables wireless personal area networks using radio waves in the 2.4 GHz band. It consumes minimal energy and is designed to connect devices in a short-range. .
