WIRELESS NETWORKS IN DIFFERENT FORMS AT THE PRESENT SCNEARIO

Abstract

There are four different kinds of wireless networks, each with a specific purpose: Wireless LANs, MANs, HANs, and WLANs all refer to different types of wireless networks that cover different distances. Internet connectivity is made available inside buildings or in a small open space using wireless LAN (WLAN) technology.  Wireless local area network technology is not only common in homes and offices, but also in public areas like cafes and restaurants. As a result of the COVID-19 pandemic, many people were forced to work and attend classes from home, leading to a dramatic increase in the use of private networks. Most household networks can be easily set up. The wire or fibre from a nearby service supplier is connected to a router. The modem is linked to a wifi gateway, which takes in the data. The wireless access point (AP), which is also the gateway, transmits using a wireless algorithm, such as the 802.11 standards. Office networks have more moving parts. The majority of APs are ceiling-mounted and each sends out a wireless signal to the nearby area. Large workplaces require multiple APs, with each one linked to a router and connected to the office backbone network. The support for users moving through the workplace area is coordinated by the APs, and the support for keeping open, linked sessions is passed from AP to AP.
