தொலைதூர பார்வைகள் பார்க்கிறேன்.
சிலசமயம் சுவர்களையும் ஊடுருவி காண்கிறேன்.
என் கையின் ரேகைகள் மட்டும் புரியவில்லை இன்னும்.

Wi-fi
Working of Wi-fi
------------------
The working of wi-fi is described below.
* More than one clients and Access Points are connected in a typical wi-fi connection.
* An AP(Access Point) broadcasts its Service Set Identifier(SSID) via frames.
* The frames are known as beacons.
* Beacons are transmitted at a speed of minimum 1Mbps.
* So the minimum speed of wi-fi is 1 Mbps.
* If two APs of the same SSID are in range of the client, the firmware may decide based on signal strength to which of the two APs it will connect.
* In wi-fi standards user has the power to decide the connection criteria.
* Since Wi-Fi transmits in the air, it has the same properties as non-switched ethernet
network.
Examples of Wireless devices are
1. Wireless routers
2. Wireless Acess Point (WAP)
3. Wireless Adapter
4. Range extender
