Wi-fi (ppt) by Mayank Saxena
WiFi (Wireless Fidelity) is a wireless technology that uses radio waves to provide wireless internet access in local areas. It allows devices to connect to the internet without being physically connected with cables. The first wireless products using this technology were introduced in 1991 under the name WaveLAN. WiFi operates in the 2.4GHz and 5GHz radio bands and allows devices to connect within a range of around 100 feet from an access point. It provides wireless internet access through WiFi hotspots that can be either open for public use or secure networks requiring a password. The 802.11 WiFi standards have continued to evolve with improvements to speed and security.

A Wi-Fi network works by creating a hotspot using an access point connected to the internet, which wireless enabled devices can then connect to within a range of 100 to 300 feet. Wi-Fi networks can be implemented in either an ad-hoc or infrastructure mode and have advantages like mobility, ease of installation, flexibility and cost savings over
WIFI Introduction (PART I)
WiFi, also known as 802.11, allows devices to connect to a wireless network without needing wires. An access point is connected to the internet and creates a WiFi hotspot with a range of 100-150 feet indoors. Devices within this range can then connect wirelessly to browse the internet. WiFi standards like 802.11b and g operate at 2.4GHz while 802.11a and n can also use 5GHz. Later standards offer faster speeds and greater ranges. WiFi is popular for homes, small businesses, and public places as it offers mobility and easy installation without wired connections. Potential limitations include interference and limited range compared to wired networks.

Wi fi
Wi-Fi is a wireless technology that allows devices to connect to the internet and exchange data wirelessly using radio waves. It was invented in 1991 and standardized as IEEE 802.11. Wi-Fi uses radio frequencies between 2.4GHz and 5GHz to transmit data over distances of up to 150 feet indoors and 300 feet outdoors. It enables wireless internet access through base stations called access points that broadcast signals for wireless devices to connect to. The technology has various applications and advantages like mobility and reduced installation costs but also faces limitations like interference and security issues.
Wireless technology - Wi-Fi
Wi-Fi is a wireless networking technology that allows devices to connect to the Internet without being physically connected with wires. It uses radio waves to transmit data between devices like computers, smartphones and access points. Common standards include 802.11b, 802.11g and 802.11n. Wi-Fi networks have advantages like mobility and easy installation but also limitations such as limited range, security risks from interference and potential hacks. Basic security techniques are used to encrypt Wi-Fi connections and protect data transmission.
