Synopsis
Wi-Fi and Bluetooth
Short form of Wireless Fidelity. This can be defined as a wireless Local Area Networking System.
Can you imagine a day without Internet? For me it is not possible. That means now internet has become an integral part of our life.
With the help of Wi-Fi, we can access broad band internet connection with high data transfer rate.
The main attractive feature of this technology is that it can provide wireless broadband connection within a specific
geographic boundary.

Locating Hotspots
There are many WiFi hotspots now available in public places like restaurants, hotels, libraries
and airports. For example, Starbucks.
The number of hotspots in the world is growing daily.
One way to find a hotspot is to go on-line.
Wi-Fi and Bluetooth
We can access internet through our laptop.
With the help of this technology Tourism Department of Srinagar is looking forward for a very good
response from the tourists.
And they believe that in the near future itself, there will be a good change in tourism industry in Kasmir.
Now Kashmir is getting a good image among world tourist map.
So Wi-Fi is rocking. Isn't it?

WEP stands for Wired Equivalency Privacy
As its name implies, this standard was intended to make wireless networks as secure as wired networks.
The common key lengths are currently 128- and 256-bit.
WPA Wi-Fi Protected Access is an early version of the 802.11i security standard that was developed by the Wi-Fi Alliance to replace WEP.

PiconetPiconet "Piconet" is a combination of the prefix "pico," meaning very
small or one trillionth, and network.
A network of devices connected in an ad hoc fashion using Bluetooth technology.
The connection is established for the duration of one session and requires no base station is called ad hoc.
A piconet is formed when at least two devices, such as a portable PC and a cellular phone, connect. A piconet can support up to eight devices.
When a piconet is formed, one device acts as the master while the others act as slaves for the duration of the piconet
connection.

All devices in piconet hop together.
Master’s ID and master’s clock determines frequency hopping
sequence & phase.
