Where Did Wifi Come From

What Does Wi Fi Stand For?

WiFi, or wireless networking as it should be referred to, before it became a staple computer accessory, is a technology thats actually much older than most people think. First tinkered with by a professor at the University of Hawaii named Norman Abramson, the act of transmitting data over the air was first achieved via HAM radio in 1971, though the technology that made it work was downright primitive by todays standards.

Due to the huge expense of the equipment that was required to make a HAM setup work, wireless would sit dormant on the shelves until the mid-90s when various formats and wireless frequencies were being proposed as the standard for the band that wireless internet would occupy.

Channel Spacing Within The 24 Ghz Band

In addition to specifying the channel center frequency, 802.11 also specifies a spectral mask defining the permitted power distribution across each channel. The mask requires the signal to be attenuated a minimum of 20 dB from its peak amplitude at ±11 MHz from the center frequency, the point at which a channel is effectively 22 MHz wide. One consequence is that stations can use only every fourth or fifth channel without overlap.

Availability of channels is regulated by country, constrained in part by how each country allocates radio spectrum to various services. At one extreme, Japan permits the use of all 14 channels for 802.11b, and 113 for 802.11g/n-2.4. Other countries such as Spain initially allowed only channels 10 and 11, and France allowed only 10, 11, 12, and 13 however, Europe now allow channels 1 through 13. North America and some Central and South American countries allow only 1 through 11.

This does not mean that the technical overlap of the channels recommends the non-use of overlapping channels. The amount of inter-channel interference seen on a configuration using channels 1, 5, 9, and 13 is barely different from a three-channel configuration, but with an entire extra channel.

However, overlap between channels with more narrow spacing may cause unacceptable degradation of signal quality and throughput, particularly when users transmit near the boundaries of AP cells.

What Is A Wireless Router

Wireless routers are commonly found in homes. They’re the hardware devices that Internet service providers use to connect you to their cable or xDSL Internet network.

A wireless router is sometimes referred to as a wireless local area network device. A wireless network is also called a Wi-Fi network.

A wireless router combines the networking functions of a wireless access point and a router. Read more about wireless routers.

What Are All Those Letters About: 80211

Youll notice in the previous paragraph, we mentioned that what started as the 802.11 standard was quickly changed to 802.11b, as the extra letter was added in order to denote the generation of wireless technology that devices could support.

For example, the b standard was the very first to come out, and could support a transmission rate of around 11Mbps on the 2.4Ghz spectrum. Next came the 802.11a standard in 2002, which was capable of transmitting upwards of 54Mbps over the newly minted 5Ghz frequency spectrum.

Fast forward to today, where the latest and hottest on the market is the 802.11ac standard, which is capable of transmitting a whopping 1.3Gbps over both the 2.4Ghz and 5Ghz spectrum at the same time.

    What Is The Difference Between Wifi And Internet Can You Have Wifi Without Internet

    Your computer can communicate with your router through a WiFi signal even if your router isnt online. Thats why you can have a strong WiFi signal with a weak or nonexistent Internet connection. Similarly, your Internet router can have a healthy Internet connection which feels like its slow to you, because of a less than ideal WiFi signal between you and your router.

    How To Connect To A Wifi

    In order to connect to Wi-Fi, a computer must have a wireless network interface controller . The combination of an interface controller and a computer is called a station. Stations are identified by one or more media access control addresses .

    WiFi nodes usually operate in infrastructure mode where all communications go through a base station. Ad hoc mode refers to devices talking directly to each other without the need to first talk to an access point.

    A service set is the set of all the devices that is related to a particular WiFi network. Those devices dont have to be on the same wavebands or channels. A service set can be local, extended, mesh, independent, or a combination of them.

    Each service set has a related identifier. The 32-byte Service Set Identifier identifies the particular network. The SSID is configured within the devices that are considered a necessary part of the network.

    While a Basic Service Set is a group of stations that all share the same wireless channel, SSID, as well as other wireless settings that have the same access point. Each BSS is identified by a MAC address that is known as the BSSID.

    Wireless Ad Hoc Network

    A wireless ad hoc network, also known as a wireless mesh network or mobile ad hoc network , is a wireless network made up of radio nodes organized in a mesh topology. Each node forwards messages on behalf of the other nodes and each node performs routing. Ad hoc networks can “self-heal”, automatically re-routing around a node that has lost power. Various network layer protocols are needed to realize ad hoc mobile networks, such as Distance Sequenced Distance Vector routing, Associativity-Based Routing, Ad hoc on-demand Distance Vector routing, and Dynamic source routing.

    How To Reduce Public Wifi Security Risks

    What Does Wi-Fi Stand For

    Although the encryption that is widely used in web browsing and email delivery will help protect you from attacks, it isnt perfect and isnt used everywhere. It can be hard to see when it isnt used, where its weak, or where it might be vulnerable to downgrade attacks, particularly in mobile apps, all of which can be exploited by attackers.

    You can also use a Virtual Private Network to secure your traffic when using public WiFi connections. By wrapping your imperfectly-encrypted traffic in a single, impenetrable tunnel, the best VPN services will keep your data safe from rogue WiFi hotspots and attempts to intercept your communications. You can also read up on VPN protocols to learn about how they secure your connection.

    A top VPN service also protects your privacy by cloaking your IP address. Privacy threats can sometimes come from unlikely sources. For example, a Dutch city was recently fined for trailing its citizens with a WiFi tracking system.

    Turn WiFi off on your devices when you dont need them. Itll make your battery last longer and it stops your device being used as a tracking beacon.

    What Is A Wireless Access Point

    A wireless access point allows wireless devices to connect to the wireless network. Having a Cisco wireless network makes it easy to bring new devices online and provides flexible support to mobile workers.

    What a wireless access point does for your network is similar to what an amplifier does for your home stereo. An access point takes the bandwidth coming from a router and stretches it so that many devices can go on the network from farther distances away. But a wireless access point does more than simply extend Wi-Fi. It can also give useful data about the devices on the network, provide proactive security, and serve many other practical purposes.

    What Happened To Wi

    After the great success of Wi-Fi, Wi-Max was marketed as the next big thing. It was much faster than any other internet connection at that time. And it was a long time since the launch of 3G many people even thought that Wi-Max could be accepted as the standard for 4G. It was even promised to be the best option for a citywide Wi-Fi.

    But Wi-Max vanished without any trace.

    You cannot find Wi-Max anywhere. The main reason behind this is the lack of funding. The people that were developing this technology did not get investors to make it commercial. Some internet service providers opted for it, but not for long. Soon, LTE was launched, which became the standard for 4G. All the service providers switched to it and forgot about Wi-Max.

    The technology used in Wi-Max was also not good for a citywide Wi-Fi. It was cheap, but not good.

    Most Important Wifi Terminology

    Now that weve explained what WiFi stands for and provided you with a widely accepted WiFi definition, its time to take a closer look at some of the most important WiFi terminology. As you can probably imagine, we can only scratch the surface of the IEEE 802.11 standard here, but knowing the terms described below should be enough to help you make wise purchasing decisions when buying a new WiFi router or selecting a new internet provider.

    Regulatory Domains And Legal Compliance

    What Does WiFi Stand For? (Full Explanation)

    IEEE uses the phrase regdomain to refer to a legal regulatory region. Different countries define different levels of allowable transmitter power, time that a channel can be occupied, and different available channels. Domain codes are specified for the United States, Canada, ETSI , Spain, France, Japan, and China.

    Most Wi-Fi certified devices default to regdomain 0, which means least common denominator settings, i.e., the device will not transmit at a power above the allowable power in any nation, nor will it use frequencies that are not permitted in any nation.

    The regdomain setting is often made difficult or impossible to change so that the end-users do not conflict with local regulatory agencies such as the United States’ Federal Communications Commission.

    What Is A Desktop Wi

    The most common way for users to connect to the Internet wirelessly is with a desktop wireless router. These routers look like small boxes with multiple short antennas to help broadcast the signal throughout a home or workplace. The farther a user is from the base Wi-Fi router, the weaker the signal. So multiple wireless routers, called range extenders, usually are placed throughout the workspace. Wi-Fi range extenders, placed in an array, boost or extend Internet coverage.

    Here’s Why It’s Called ‘wi

    Do you have Wi-Fi? Whats the Wi-Fi password? The Wi-Fi is so slow right now!

    In 2019, the term Wi-Fi comes up frequently. But do you know what Wi-Fi actually stands for? Or how it got this name? HuffPost decided to explore Wi-Fis origin story.

    You may be under the impression that Wi-Fi is short for wireless fidelity. But you would be wrong.

    It turns out Wi-Fi stands for … nothing.

    Wi-Fi is a registered trademark of the Wi-Fi Alliance, formerly known as the Wireless Ethernet Compatibility Alliance.

    Wi-Fi Alliance founding member Phil Belanger shared the history of the term with Boing Boing back in 2005. It seems the wireless industry was seeking a user-friendly name to refer to technology that adhered to standards known as IEEE 802.11.

    We needed something that was a little catchier than IEEE 802.11b Direct Sequence, he explained. The Wi-Fi Alliance hired Interbrand to come up with ideas, and the brand consultancy proposed 10 names, including Wi-Fi .

    The only reason that you hear anything about Wireless Fidelity is some of my colleagues in the group were afraid. They didnt understand branding or marketing. They could not imagine using the name Wi-Fi without having some sort of literal explanation, Belanger continued. So we compromised and agreed to include the tag line The Standard for Wireless Fidelity along with the name. This was a mistake and only served to confuse people and dilute the brand.

    What Is A Wifi Hotspot

    A WiFi hotspot is any physical location where a device can connect to the Internet through a Wireless Local Area Network . Nowadays, you can easily create a WiFi hotspot with a modern smart device. For example, most smartphones can produce a WiFi hotspot, which effectively turns them into an Internet-connected WiFi router. Any wireless-capable device in range can use it to connect to the Internet in the same way as they would use an Internet router at home.

    How To Use A Secured Wifi Network

    What does WiFi stand for?

    Your security is the most important thing when using the internet.

    This security is at significant risk when you are using a WIFI or lets me correct, a public WIFI.

    In such cases, your data is being shared with hundreds of people.

    Following the guidance below you can be secured while using it.

    • It is quite common to have settings enabled on the home network to share and receive files from other devices on the same network, but when using a public network, you should switch off the settings.
    • From your security settings enable the firewall.
    • Dont forget to write https before a web address. In this case, your privacy will be safe from evil hands.
    • It is standard practice to enable WIFI on a home network even when there is no use of it, but when being on a public network switch off the WIFI if there is no need of using it.
    • Try to use a virtual private network. VPN is the most secure way. There are many free internet apps and VPN which will make you secure.
    • Check your antivirus. Switch it on and Dont forget to keep it up to date.
    • Avoid doing any work on a public network that involves sending any sensitive data.
    • Dont forget to log out from your account when your work is finish.
    • It is the area in which the WIFI is accessible.
    • This can be public or any closed network.
    • You can make a device a hotspot and can connect another device to the internet by that instrument.

    How Did Wifi Become An Official Standard

    Until 1997, the world couldnt quite agree on a common and compatible WiFi standard. Then, a group of industry experts formed a committee to decide. Think of them like the council from Lord of the Rings but tech-savvy and with less pointy ears.

    Not only did the committee agree on a wireless communication standard, but they formed an alliance called the Wireless Ethernet Compatibility Alliance . In 2002, WECA was rebranded to WiFi Alliance, which features hundreds of renowned member companies today. Pointy ears still isnt a requirement for joining.
