WiFi Full Form Name: WiFi Meaning
Full Form of WiFi :
Wireless Fidelity
WiFi Full
Form is Wireless Fidelity. It normally
refers to systems that use 802.11 standards developed and released by IEEE or
Institute of Electrical and Electronic Engineers in the year 1997. Initially,
this system was promoted largely by a trade group called ‘Wi-Fi Alliance’,
which mastered commercialization of technology and eventually it reached its
pinnacle. This could possibly be the reason why WiFi full form has its name.
What is WiFi all about?
WiFi is actually a technology
that uses wireless networking of two or more devices. These devices are
normally connected to the wireless network within a limited area (for example
within a building) and can access the internet. Communication between the
devices takes place using radio signals.
WiFi Full Form – Additional Information
Imagine the world without
internet, especially now when everything is available and functions on the
internet. It is admittedly hard to imagine the world devoid of this amazing
human invention that has revolutionized our lives roughly since two decades.
The infinite space and content on Internet facilitate robust and quicker
communications, searches, and execution of other jobs.
The Internet has become a popular
word in the human vocabulary and even in the remotest areas, the word
“Internet” is ubiquitously used. With the advent of Wi-Fi, internet users have
become more mobile as the convenience of access is a special feature
attributable to Wi-Fi. Wi-Fi has become fashionable in the implementation of
development programs across the world, as the world leaders are pushing efforts
to make people conscious of everyday changes.
Wi-Fi is being installed in
shopping malls, hospitals, police stations, and even districts to facilitate
access to Wi-Fi to people, with or without charges. Countries have become
participants in the digitalisation drive, in order to achieve strong
inter-communications among people and improve the administrative abilities of
the governance system. It is necessary to understand and respect the importance
of Wi-Fi, as it is responsible for the much-demanded comfort we enjoy. Here are
ten things about Wi-Fi, which everyone must know to appreciate its relevance.
History of Wi-Fi:
Wi-Fi has an interesting history
that is reflective of many things: its purposes, utilities, and current
relevance. By knowing history, it would become easier to explore other
dimensions of Wi-Fi, which often remain untouched in public discussions or
otherwise. It all started in Hawaii, when in 1971 ALOHAnet connected the
Islands with a UHF wireless packet network. Following this, the United
States Federal Communications started releasing ISM band in the year 1985.
These bands were those used in microwaves and therefore, were vulnerable to
interferences.
The use of wireless network did
not claim significant popularity until 1991 when NCR
Corporation with AT&T Corporation invented the precursor to
802.11 under the name WaveLAN and marketed them for the use in cashier
machines. Not long after that, 802.11 was introduced in 1997, which originally
provided 2 Mbit/s link speed but was later updated to provide
11 Mbit/s link speed. The latter upgrade proved to be highly popular among
users. Finally in the year, the popular Wi-Fi Alliance was formed under which
most Wi-Fi products are marketed.
The name Wi-Fi:
Most of you must have, at some
point in time, wondered the origin of the name Wi-Fi, after all it is an
intriguing and likeable abbreviation. It is considered that the name was coined
somewhere around the 1990s, though the exact date is not yet confirmed, by the brand-consulting
firm Interbrand Corporation, which was hired by Wi-Fi Alliance to
decide on a catchy name for the local area wireless computing network.
It was then the name was coined
accidently, as a play on the words “Hi-Fi””. For quite a long time, Wi-Fi was
understood to mean “Wireless Fidelity”. The Wi-Fi logo is based on yin-yang
symbol that symbolizes interoperability, which is a property of a system to
work with other systems, whether present or future, without any access
impediments.
Hardware specifications of WiFi:
The properties of Wi-FI make it
more convenient than LAN networks, which require extensive wiring of cables.
Wi-Fi can be used even in spaces where wiring is not possible, like monuments.
It is now settled that any standard device with a Wi-Fi adapter will work
anywhere, irrespective of region.
Wireless adapters facilitate
connection of devices with wireless network. These adapters can be external or
internal, like, for example, many laptops manufacturers have now introduced
Wi-Fi adapters into the laptops, without much investment of financial
resources.
There are wireless routers that
integrate a Wireless Access Point, Ethernet switch, and internal router
firmware thereby, allowing wired and non-wired Ethernet LAN to connect to
a single modem, whether cable or DSL. There are also Wireless Network Bridges
and as the name sounds, they bridge wired network with a wireless network.
Lately, embedded Wi-Fi modules have become increasingly popular to provide more
convenient connectivity setting to users. These modules are designed by OEMs
(Original Equipment Manufacturer).
Range of WiFi:
The range of Wi-Fi is variable,
depending upon the frequency band, radio power output, antenna gain,
antenna type and modulation technique. In fact, range of Wi-Fi signals is
significantly affected by refraction and reflection of light. But it is
possible to improve the range by fitting upgraded antennas, also called high
gain directional antennas.
Security risks in the application of Wi-Fi:
Technology does not come without
glitches and risks and so does Wi-Fi. Wi-Fi has its own sets of network
security risks that must be known to the users indulging in internet based
services. Its greatest advantage is the main problem, which is its easier
accessibility than LANs’. One merely needs to be in the vicinity of Wi-Fi
network to connect to the Internet and this may pose serious problems to
information security.
For example, Piggybacking has
become a common problem, which relates to Wi-Fi unauthorized access. In this,
one obtains access to a wireless connection by bringing his or her computer
within the network area and using the connection without authorization. There
are however methods to secure access to Wi-Fi and thereby, securing network.
The most commonly used Wi-Fi
Protected Access (WPA and WPA2) encryption is being used to secure Wi-Fi access
from unwanted the users. It is regarded as sufficiently secure, provided a
strong pass code is used. This would provide access to Wi-Fi only to those, who
have knowledge of the pass code.
Another way of securing Wi-Fi
access is by disabling SSID broadcast, which hides the access point’s name.
This method is found effective against normal internet users, but has many
lacunae to fix when dealing with expert hackers and network breachers.
Wi-Fi and Health:
There is no gainsaying that a lot
of apprehensions exist regarding the effects of wireless network systems on
health. The World Health Organization, the pivotal international health
organization, has acknowledged anxiety towards use of electromagnetic fields
and their effects on health. With the purpose of systematically assessing
public fears on the use of wireless networks, WHO established International EMF
Project in 1996.
The project was tasked with the
duty to examine scientific effects of electromagnetic fields on public health
and produce a report on the findings. Many researches have been conducted ever
since then and all of them have reported that the use of electromagnetic
fields, which are within the frequency range of 0–300 GHz, do not produce
serious effects on public health.
There are many international
guidelines that provide for limits on the use of electromagnetic fields like
British Health Protection Agency, the International Commission on
Non-Ionizing Radiation Protection (ICNIRP), etc. These guidelines are
reflective of the global consensus that use of electromagnetic field is not
harmful, if limited within a certain frequency range.
WiFi Radio Spectrum:
The Wi-Fi radio spectrums are not
consistent worldwide like, for example, the United States uses
2.4 GHz ISM band, Australia and Europe allow for an additional
two channels for the 2.4 GHz band and Japan allows three more channels.
Wi-Fi connections are interfered
in presence of other devices in the area. Many access points default to the
main channel may experience network congestion . Also known as the Wi-Fi
Pollution, having too many access pints in a particular area can create
overlapping channels, which will ultimately disrupt internet services. This generally
occurs in populated areas, like hostels or office buildings.
Distance
Wi-Fi is an impressive
technology, with the ability to cover larger distances without much hassle and
expensive incorporations. The perception that frequent interruptions in Wi-Fi speed
or sluggish speed indicate low coverage area of Wi-Fi, that is it can only
cover very limited distances has become increasingly popular.
No, this is wrong!
Wi-Fi is an advanced technology,
with the capacity to travel great distances and potential to travel to even
greater distances. Most the Wi-Fi are for home purposes and therefore, their
range is limited to 30 m. But, however, Wi-Fi, which are to be utilize for
extensive purposes may have range even up to 275 km. Thus, it completely
depends upon the necessities of the person or the organization that wishes to
install Wi-Fi connections.
The Smartphones and Wi-Fi:
This segment has probably brought
two of the most important technological advancements together. There is no
gainsaying that these two have contributed immensely to the overall development
of inter-communication, faster services, and greater public awareness. Together
they attempt to create a global communication network under which citizens of
the world will be able to share information and learn different things about
almost everything, which is not possible physically. These two have together
formulated an amazingly useful mechanism that endeavours to create a
technologically responsive environment.
A recent study conducted in the
year 2010 found that out of randomly chosen seven million mobile devices, Apple
iPhones accounted for one fourth of the total Wi-Fi connections. Together with
Android devices and iPads, 16.53% was accounted for the total Wi-Fi connection
for the year. The percentage seems to have increased to 33% in the year 2011.
The substantial participation of the Smartphones in total Wi-Fi connections
highlights the convenience of the devices, which other devices like Desktops or
laptops fail to offer.
Uses of Wi-Fi:
We have finally come to the
segment relation to the utility of Wi-Fi. The essence of Wi-Fi is to provide
easier accessibility to Internet and its services, without much hassle. It’s
application has resulted in making life more comfortable and connected with the
other world.
The following are
some of the applications of Wi-Fi:
1. The primary purpose is of course to provide internet services to
all the connected devices within the network’s area. What is popularly known as
Hotspots, these access points can be created in small rooms or big departmental
stores. These Hotspots services can be made available free of cost or with
certain charges. Business organizations often resort to these services to
attract customers. Airport authorities, departmental stores, restaurants, etc
often provide free or minimally charged Wi-Fi services to their customers.
2. Another application of Wi-Fi is its potential to create fully
Wi-Fi enabled smart cities. Smart cities have become a fashionable in the
infrastructural development process initiated by many countries. Many countries
have proposed plans or initiated process for development of smart cities. One
of the main features of a smart city is that it provides digital connectivity
to people. It endeavours to provide internet facilities to all, considering the
powerful impact it has on the governance of social, political, and economical
life. While building smart cities is a difficult task to achieve within span of
a couple of years but a fully enable Wi-Fi system running across the city can
be achieved within a shorter period of time.
There have been many examples
like Mysore, which has become India’s first Wi-Fi enabled city in India.
Florida and Sunnyvale are some of the north American cities that offer
city-wide Wi-Fi facility. These cities have become epitome of infrastructural
development to the world, because the fact internet is available to people
easily makes these cities more responsive and digitally connected with the
world commuity.
Relevance in educational campuses:
Educational campuses have long
understood the impact of internet on the learning habits and teaching
strategies. It was not long after that universities across the globe started
installing campus-wide Wi-Fi to provide easier and quicker access to research
materials to students and faculties, and at the same time provide innovative
learning and teaching methods. This way students are more connected with news
updates, school notices, research assignments, etc and teachers are more
responsive to educational requirements of students.
Carnegie Mellon University was
the first university to build a campus wide Wi-Fi system in as early as 1993.
The legacy is now being loyally followed by universities from every nook and
corner of the world so that these education delivery institutions do not become
redundant with time.
What are the devices which can use WiFi?
WiFi can be used by many of the
electronic devices which include; smart phones, personal computers, digital
cameras, tablets, video game consoles, laptops, PDAs (Personal Digital
Assistants), digital audio players, etc..
Practical Application of WiFi:
When it comes to practical
application, a business or individual can create a ‘hot spot’ using a device
called ‘wireless router’ which enables various appropriate devices to wireless
connect and transfer data. In other words, this set up helps to access
Internet. Anyone with a WiFi device can access internet or LAN (Local Area
Network) using an access point. The only condition is that the WiFi enabled
device should be within the range of that access point.
Salient Features of WiFi:
Basically, in a given Wi-Fi
network, computers and devices with relevant network cards can wireless connect
through routers and these routers are in turn connected to Internet through
‘modems’ that offer high speed connectivity. Wireless Fidelity or Wi-Fi network
can be ‘open’ for anyone to access (or) ‘closed’ for individual usage (and is
secured with a password). The entire technology makes use of radio signals of
around 2.4 GHz for the communication.
Advantages of using WiFi:
By using WiFi technology, you can
save huge money which is otherwise spent on introducing cables and wires into
buildings. Moreover, It is easy to install and use.
WiFi Full Form: Water in Fuel Indicator
Full Form of WiFi refers to Water in Fuel Indicator. It is
a kind of indication system which tells you if there is any water presence in
the fuel. All the vehicles whether it is a diesel vehicle or petrol vehicle
come with water in fuel indicator. This indicator starts blinking when it
senses water presence in the fuel.
The dashboard of vehicles has
symbols to indicate the driver about the possible mixing of water with the
fuel. This problem arises when the separator, which removes water from the
fuel, does not function properly. Diesel vehicles in particular are prone to
the contamination of fuel with water. Water in fuel leads to reduced
performance of the vehicle. You may experience erratic idling of the engine or
the engine may completely cut out during acceleration. This issue should be
addressed as early as possible.
Full Form of WiFi: What I Find Interesting
WiFi Full Form refers to What
I Find Interesting. It is an internet slang widely used in the
social media. You can use this term to express something which interests you.
For example,
What I find really interesting
about “Full Form Dictionary” is that it is a simple website which gives full
forms of abbreviations.
