hotspot definition


 What is Hotspot definition? In this article, we will start to define what wifi or wireless network is and how it works.


Relatively speaking wifi is a new technology created over the last two years at the time of writing. However, the basis on which it is formed is not really new. Wifi is short for wireless fidelity as it is applied to connecting multiple computers. Or in other words a wireless network.


The reason it is not really new is because we have had wireless forms of communication for some time. Look no further than his fidelity stereo. The signal from the transmitter-receiver of the ration station passes wirelessly in the air until it reaches the antenna connected to your radio. 


This technology has been around for ages. But as it is applied to computers yes it is something very new.


How Does Wireless Networking Work?


The 802.11 hotspot standard on which networks are based defines two modes that are infrastructure mode and ad-hoc mode. In infrastructure mode, the wireless network consists of at least one access point connected to the wired network infrastructure that includes a set of wireless end stations. 


This particular configuration is called a basic service system or BSS. An extended service array or ESS is a set of multiple BSSs that form a single subnet. Because most WLAN networks require wired LAN access for services such as file servers, printers, and Internet links they typically operate in infrastructure mode.


The difference between ad hoc mode and infrastructure mode is that ad hoc mode is just a set of 802.11 wireless stations that communicate directly with each other without using any access point or connection to a wired network. 


This mode is great for setting up a wireless network quickly and easily where wireless infrastructure does not exist or is simply not needed for services. Some places where this would be true are hotel rooms, conference centers, and airports, or any place where wired networks are prohibited.


While connected to a wireless network you can do the most basic things that are not too intense such as checking email, surfing the Internet, connecting to conferences, accessing your home directory, using programs such as a word processor in the network, and using print services. 


You should not use wireless networks For streaming audio or video downloading anything big or viewing graphics-intensive websites.


Although nice wireless networks look you will still get the best performance and highest speeds from wired networks. In general definition, a wireless connection works in the same way as an Ethernet connection


The speed of a wireless network is about 11 megabits per second. The problem is that with a wireless network you have to share the bandwidth with all the users connected to the wireless network on a given network. 


This is what slows down the network and makes it difficult to perform intensive operations. This is why wireless networks will never be as fast as a wired Ethernet network.


What is Wifi?


Hotspot definition of wifi or wireless access points - The Wireless Fidelity invented by the international organization to test the friendship and accompaniment. Wi-Fi is interconnected to the 802.11 standards designed by the IEEE and creates the beginnings of wireless building. 


Wireless access points or Wireless communication define many ways to build a connection between the transmitter and the receiver such as DSSS, FHSS, IR - Infrared, and OFDM. In 1997 the Institute of Electrical and Electronics Engineers introduced 802.11 which carried higher capabilities and the world-famous Cisco systems or 3COM interested in this technology. 


At first, the price of Wifi was very high but in 2002 came some product that has the ability to work in the new 802.11g standard then in 2003 this standard was sanctioned by the IEEE and went on display. With the uses of 802.11a and 802.11b, you can now work as mobile and BSS cover your desired area by dividing it into AP controlled cells.


Wi-Fi is freedom so you can connect to the internet from anywhere like at home in the office or in a public place without any wire. 


Wi-Fi is much faster than the modem and the use of different amplifiers helps change our location in a large area. With a WiFi hotspot, you can use wifi in-home business because it is very simple to manage. Hotspot definition | A hotspot of Wi-Fi is a location where wireless technology is available for use by customers. 


In some cases it is free and some providers charge a fee. Standard devices such as PCI, miniPCI, USB, Cardbus, and PC Card, ExpressCard make it more convenient. Distance recorders like Arno Pietrosomoli and EsLaRed from Venezuela are used for distance purposes.


Embedded system that corresponds with every other node on the Internet. Wifi router allows internet gateway including Ethernet, switch, PCI card, hub, and DHCP.

There are various tools for Wifi software. You can use Aircrack-ng if you are looking for multiple platforms. 


For windows use KNS GEN II, NetStumbler, OmniPeek, Stumbverter, WiFi Hopper, APTools, and if you use Unix, you can use Aircrack, Aircrack-btw, AirSnort, CoWPAtty, Karma, etc. For Mac users MacStumble, KisMAC, Kismet are the best. With the association of wifi tools, your window becomes more useful.


As is well-known Wifi uses radio technologies that offer secure and consistent connectivity with 2.4GHz and 5GHz radio bands dependent on wireless hardware such as Ethernet protocol and CSMA and CA enable route sharing. 


Originally PSK was used but now CCK was frequently used. There are different spectra used in Wifi like FHSS and DSSS and different standard operating WiFi such as 802.11b which is the most popular technology used as a wireless network and operates a 2.40 GHz band - 2.4835 GHz for activating Bluetooth strategy cell phones and scientific equipment 802.11 has a range of 5.725 GHz up to 5.850 GHz and provide up to 54 Mbps speed 802.11g cover three channels that do not overlap and enable PBCC 802.11e provide sufficient quality and offer video, audio, voice channel, etc. 


Hotspot definition | You can connect to WiFi using a card adapter and you need to know about SSID infrastructure and data encryption. Security secures your privacy through MAC ID filtering static IP address and WEP encryption.
