Wireless Area Networks

Wireless area network wireless technology is becoming an increasingly important part of today's world. From medical and retail to academic circles all over the world, wireless systems are enhancing the speed and convenience of sending and receiving data. Two specific examples of wireless technologies used today by individuals and experts are the local area network (LAN) and the personal area network (PAN). Wireless local area networks or LANs are flexible data communication systems implemented as extensions or alternatives to wired local area networks.

Wireless networks can be roughly divided into wireless personal area networks (WPANs), wireless local area networks (WLANs), and wireless wide area networks (WWANs). WPAN operates within a few feet, WLAN operates within hundreds of feet, and WWAN operates within this range. Indeed, wireless WAN can operate in a wide range of areas, including metropolitan areas, mobile phone levels, and inter-city links via microwave relay. This article covers wireless technologies in the WLAN, WPAN, and WWAN domains, among others, IEEE 802.11 WLAN (commonly referred to as Wi-Fi®), WPAN Bluetooth (BT), and WWAN's WiMAX as a representative technology . It discusses important aspects of technical media access and connectivity to wired networks - in the end it lists some general (false) recognition of wireless technology.

Wireless network standards cover specific market areas such as North America, Europe and Asia. Generally, wireless networks can be categorized as WLAN, wireless personal area network (WPAN), wireless metropolitan area network (WMAN), and wireless wide area network (WWAN), including cellular networks and satellite networks. They are summarized in the table below.

A wireless wide area network is a wireless network that normally covers a wide area, such as between neighboring cities or cities and suburbs. These networks can be used to connect to a branch office of a company or to connect as a public internet access system. Wireless connection between access points is usually a point-to-point microwave link using a parabolic antenna in the 2.4 GHz band, not an omnidirectional antenna used in a small network. A typical system includes a base station gateway, an access point, and a wireless bridge relay. The other configuration is a mesh system in which each access point also functions as a relay. When used in combination with renewable energy systems such as photovoltaic panels and wind power generation systems, it can be a standalone system.
