Its usual that many of the smartphones provide WiFi and other facilities in it.
We use WiFi to connect our Laptops,transfer data,connect to internet....so on.
Did you ever think of how it really works..??
If no, then feel free to read this post which makes each of you get through the concept behind it from a layman's mindset...:-)
Wifi: WiFi
is a popular Technology that allows any electronic device to exchange
data through radio waves/signals over a computer network, including
high-speed Internet connections.
IEEE 802.11 is a set of standards(Set of Protocols/Rules) for implementing wireless local area network (WLAN) computer communication in the 2.4, 3.6 and 5 GHz frequency bands.
"Wi-Fi" is a trademark of the Wi-Fi Alliance and the brand name for products using the IEEE 802.11 family of standards.
Wi-Fi is finely defined as any "Wireless Local Area Network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards".
IEEE 802.11 is a set of standards(Set of Protocols/Rules) for implementing wireless local area network (WLAN) computer communication in the 2.4, 3.6 and 5 GHz frequency bands.
A
device that can use Wi-Fi (such as a personal computer, video game
console, smartphone, tablet, or digital audio player) can connect to a
network resource such as the Internet via a wireless network access
point(otherwise called as a HOTSPOT)
has a range of about 20 meters (65 feet) indoors and a greater range
outdoors.
Hotspot coverage can comprise an area as small as a single
room with walls that block radio waves or as large as many square miles —
this is achieved by using multiple overlapping access points.
WORKING: The network will have a device called a wireless router which physically
attaches to the incoming network and thus the Internet via high speed
broadband or cable.
The wireless router takes the physically transmitted
data and converts it to radio waves, which it transmits via its
antennae.
The router also reverses this process by taking information
from wireless sources (such as a computer) and translates them from the
radio waves into language for the physically connected Internet
connection to use.Data is transmitted by being converted from its binary form of zeroes and ones into radio wave media.
The newly converted data is then
broadcasted and intercepted by wireless adapters, which then transform
the radio data into zeroes and ones for the computer to understand.
Wireless networks use radio frequencies of 2.4 GHz or 5 GHz. Using a
higher frequency allows for more data to be transmitted.
Working on WiFi can offer you the benefits as follows
- Flexibility:
The lack of cables that comes with wireless networking enables you to
roam with your mobile PC.
You can roam from your office to a nearby conference room for a meeting, or from the couch in the living room to a kitchen for a snack.
For example, if you're working on wireless in a meeting you can printout a report for a co-worker without having to leave the meeting.
- Time-saving:
If you're waiting for an important response you can use your mobile PC
to monitor your email even when you're in meetings or at lunch.
As soon as you get the data needed, you can promptly forward it to your customer rather than wondering whether the information has come in while you were away and having to run back to your office between meetings and other commitments.
- Increased productivity:
Working on wireless enables you to turn down times between meetings or
while in transit into productive time.
For example, you may be attending a conference and just found out that one of the sessions you were planning on attending has been cancelled.
Rather than waste the next hour, you can check email, start compiling your trip report, or order your son's birthday present.
- Easier collaboration:
Using wireless mobile PCs, you can easily share files and information
with others.
For example, you can collaborate on a presentation with colleagues during a flight delay in an airport lounge, or you can share the syllabus of a course while attendees so that they can take more digitally during the class.
