The article highlights the significance of Wi-Fi technology in present-day Indian business organizations. Its primary aim is to enhance comprehension of Wi-Fi technology and its integration into Indian businesses. In today's era of technological advancements, network connectivity through diverse devices like computers, laptops, and cell phones plays a crucial role in organizational survival. The paper elucidates how Wi-Fi works by facilitating internet connection via radio waves sans cords or cables. Additionally, it mentions that Wi-Fi is a wireless brand owned by the Wi-Fi Alliance that produces compatible products founded on IEEE 802 family standards.

The procedure for Wi-Fi certification involves the assessment of interoperability based on 11 standards and established protocols. Products that successfully complete the testing process are granted permission to display the Wi-Fi logo on their packaging. Wi-Fi technolog

y functions by transmitting radio waves from antennas and routers to devices fitted with Wi-Fi cards, such as cell phones and computers.

Wi-Fi signals can travel up to 300-500 feet for antennas and 100-150 feet for routers. By catching these signals, computers can connect wirelessly to the internet without cords. The connection speed is faster when the computer is closer to the signal source, while moving away may decrease it. Laptops come with built-in Wi-Fi cards or users may opt for external options such as USB antenna attachments connected via USB ports or antenna-equipped expansion cards installed directly onto their computers.

For laptops that do not have Wi-Fi cards, external installation is the norm. On the other hand, internal installation is prevalent for PCs. To connect to fee-based networks, a login screen and password are necessary while free networks may be available in specific places. Wireless hot spot

are emerging worldwide in urban areas to offer wireless internet access to laptop users.

A wireless access point for internet connection is established by a compact tool known as a Wi-Fi hotspot. It can be found in communal places such as hotels, libraries, airports, and restaurants and connects to the web through a wired connection. The radios utilized for Wi-Fi communication are capable of bidirectional transmission of radio waves and converting digital data into radio waves and vice versa.

There are two primary differences between Wi-Fi radios and other types of radios. Firstly, Wi-Fi radios operate at higher frequencies (2.4GHz or 5GHz), enabling the transmission of more significant data than those used for cell phones, walkie-talkies, and televisions. Secondly, Wi-Fi radios adhere to the 802.11 networking standards.

Wi-Fi technology utilizes three frequency bands for transmission and can quickly switch between them through frequency hopping. This feature minimizes interference and enables multiple devices with wireless adapters to simultaneously share a single wireless connection, providing a convenient and inconspicuous connection that is reasonably reliable. Nevertheless, if the router experiences technical difficulties or numerous users attempt to use high-bandwidth applications at once, it may lead to interference and disconnection.

The 802.11 standard has been released by the IEEE in a chronological sequence, consisting of three versions: 802.11b, 802.11a, and 802.11g.

The table below displays the primary differences between each standard, including their respective and contents:

The following information pertains to the 11g wireless network. The network speed for this system is 11 Mbps and can reach up to 54Mbps. The range indoors is between 100-150 feet and between 27-75 feet indoors. The frequency for this network is 2.4GHz, which is already crowded with cordless phones, and the acceptance of hot spots has already been established using 802.11b. However, the 5GHz frequency is an uncrowded band.

Equipment for Wi-Fi is readily available, especially in corporate and office environments. 802.11g is compatible with 802.11b, making it useable on networks based on either version. Wi-Fi is increasingly being used in Indian enterprises to provide support for fast roaming, increased network capacity, and wireless voice applications (VoWLAN or WVOIP). This is achieved by increasing the number of access points and using more channels or creating smaller cells.

While Wi-Fi usage has been readily adopted by specific LAN user segments such as educational institutions and the hospitality industry, other enterprises have been more hesitant. Nevertheless, some have discovered inventive methods for employing Wi-Fi within their networks. For instance, LG Electronics India Ltd. relies on its Wi-Fi infrastructure to support business-critical applications like an internal ERP system and Lotus Notes, while also providing Internet access to its plant and executive employees. The 802.

The 47-acre campus of 1b solution in Noida now has a Wi-Fi solution that saves time and resources while also taking care of cable management, a typically difficult and expensive task. Meanwhile, Sumul Dairy in Gujarat, which is a part of the Surat District Cooperative Milk Producers' Union Limited, uses 12 Access Points (APs) to share mission-critical data between various internal departments

such as the boardroom, veterinary department, by-products and finished products sections, and ERP servers across its two square kilometer campus. According to Satyen Naik, Assistant Manager (IS) of the company, the deployment of Wi-Fi has helped the company reduce costs and maintenance issues. P&O Ports in Navi Mumbai also utilizes Wi-Fi technology for remote controlling heavy cranes used for loading cargo onto ships.

Previously, the cranes in the port were controlled using wires from base stations located over 100 meters away. The cranes' movement would sometimes result in the cables being cut. However, the organization has now solved this problem by utilizing 802.1b technology to connect the cranes and base stations. As a result of this improvement, the cranes can now move freely and uninterrupted in the port.

Jindal Strips Limited, which is a part of a steel conglomerate in Haryana, needed to connect its Cold Roll Division with its HR and Administration Division. Although the two division's offices were situated across the road from each other, there was a railway track planted squarely between them. To establish connectivity, the company initially used optic fibre links; however, these links proved to be ineffective due to continuous road repairs and the intense heat generated from the furnaces which was too harsh for the fibre. Therefore, Jindal Strips Limited deployed an 11 Mbps WLAN building-to-building bridge with an omni-direction antenna and other Wi-Fi equipment on the premises. Consequently, the connectivity links are now always up, allowing the company to seamlessly share vital business data without experiencing any downtime.

The Guntur collectorate in Andhra Pradesh needed to connect to the Andhra Pradesh State-Wide Area Network (APSWAN) for e-governance purposes. However, since

traditional leased lines were not an option, they chose WLAN links for transmitting necessary information. Wi-Fi installations have improved since 2007 and now offer secure computer networking gateway, firewall, DHCP server, and intrusion detection systems. Consumers can also access the internet, VoIP phone service, gaming, and networking for various electronic devices such as televisions, DVD players, digital cameras, MP3 players and PDAs through Wi-Fi connections. The benefit of deploying LANs without cabling for client devices reduces both network deployment and expansion costs.

Wi-Fi, also known as Wireless LANs, is a practical option for places where installing cables presents challenges, such as outdoor areas and historical buildings. The incorporation of Wi-Fi in corporate infrastructure has allowed the use of RFID technology that can make use of Wi-Fi. Unlike mobile phones, Wi-Fi functions on universally standardized protocols, enabling standard Wi-Fi devices to operate globally. Although utilizing strong passwords can strengthen WPA security, WPA2 encryption currently has no known vulnerabilities. Nonetheless, there are global inconsistencies and limitations when it comes to spectrum assignments while some low-bandwidth standards consume relatively high power. Moreover, overcrowding access points may lead to pollution or restrict accessibility since the range of Wi-Fi networks is restricted.
