This document summarizes the key aspects of routers and Wi-Fi technology. It explains that routers are networking devices that forward data packets between computer networks by reading information in the packets to determine the ultimate destination. It then describes that Wi-Fi uses radio frequency to transmit data wirelessly as an alternative to wired technology. Finally, it outlines some of the advantages of Wi-Fi including no wires, fast deployment and ease of installation, while also noting disadvantages such as slower speeds, limited range, and data security risks compared to wired connections.

LIMITIATIONS

2.  A ROUTER IS A NETWORKING DEVICE THAT
FORWARDS DATA PACKETS BETWEEEN
COMPUTER NETWORKS.
 A ROUTER IS CONNECTED TO TWO OR MORE
DATA LINES FROM ONE SINGLE NETWORK.
 WHEN A DATA PACKETS COME IN ON ONE OF
THE LINES, ROUTER READS THE INFORMATION
IN THE PACKET TO DETERMINE ITS ULTIMATE
DESTINATION

3. WI-FI i.e. wireless fidelity is wireless technology
that uses radio frequency to transmit data
through the air
Wi-Fi (wireless technology) is an alternative to
Technology , which is commonly used ,for
connecting devices in wireless using radio waves

4.  Back in 1991 wi-fi was invented by NCR
Coporation in Netherlands.
 The first wireless products were brought on
the market under the name WaveLan with
speeds of 1mbs/2Mbs

 Vic Hayes who is the inventor of wifi has been
named “father of wi-fi”

5. WI-FI TECHNOLOGY USES RADIO SINGNALS TO
TRANSMIT DATA JUST LIKE OUR OLD RADIO SETS, TVS
AND WALKIE-TALKIES.
THE WIRELESS ADAPTER OF THE DEVICE TRANSLATES
DIGITAL DATA TO RADIO SIGNALS
SIGINAL ARE THEN TRANSMITTED OVER THE ANTENNA
ROUTER RECIEVES THE SIGNAL AND DECODES THEM.

10.  No Wires-A truly wireless networking solution.
 No Waiting- Fast, easy, deployments.
 No Worries-A wireless networking system that is
secure, easy to manage, and built to grow with you.
 Ease of installation – Quick, easy setup.
 Fast data transfer rates.

12. SPEED - Slower than cable
Range –Affected by various medium.
Travels best through open space.
Reduced by walls ,glass ,water , etc.
Security-Greater exposure to risks.
Unauthorized access.
Compromising data.
Denial of service.

13.  Limited range
 Data security risks: a huge challenge for Wi-Fi
networks.
 Interference from other devices: such as telephones,
microwave ovens.
 High power consumption: making battery life and heat
a concern.
