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 be why the full form of WiFi has its name.
What is Wi-Fi all about?
Wi Fi 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 the 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 world leaders are pushing efforts to make people conscious of everyday changes. Wi Fi full form
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 digitalization drive, in order to achieve strong inter-communication 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 Full Form
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: WiFi ka full Form
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 likable 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 accidentally, 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 the 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: WiFi meaning
The range of Wi-Fi is variable, depending upon the frequency band, radio power output, antenna gain, antenna type and modulation technique. In fact, the 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 the 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 the 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: Full form of wifi
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.
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 endeavors 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:
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.
Another application of Wi-Fi is its potential to create fully Wi-Fi-enabled smart cities. Smart cities have become 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 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.
