All about Wi-Fi, It’s Connections, Its Frequencies, Hotspots, Etc
Wi-Fi needs no introduction. Starting from the institutions, industries, airports, to even shopping complexes, people look for it everywhere in contemporary life. Wi-Fi is a technology that provides web connectivity to a device within the network. A tool gets Wi-Fi connection through a wireless adapter for the generation of hotspots.
Hotspots are the zones in the surrounding area that are linked to the network, and let the user in enjoying web access. After being configured, the devices enjoy wireless connectivity through the Wi-Fi. In general, the frequency of the waves in such connections is set under the data requirement of the particular network.
However, the frequencies around two to five GHz can fulfil most of the requirements. Wi-Fi is technically also known as 802.11 networking. This is such as it is based on the IEEE 802.11 technologies.
The best part of Wi-Fi is its ability to be attuned with all sorts of operating systems. At the same time, the technology can be accompanied with gaming devices and high-end printers as well.
How Wi-Fi Provides Connection
The functionality of the Wi-Fi network is also based on the radio waves, just like smartphones. It uses the radio waves to transfer data from one system to the other.
However, the device needs a wireless adapter through which the data sent is converted into radio signals. The signal is then transferred to the router through an antenna.
After being successfully decoded, the data is transferred to the web through Ethernet connections. These Ethernet connections are wired connections. Wireless networks function like double way traffic. Hence, the data absorbed through the internet is also going to transmit through the router, which is coded into a radio signal. The device’s wireless adapter then receives the radio signal.
Wi-Fi Frequencies and Networks
As explained above, the wireless network generally transmits information within the frequency band of 2.4 GHz or 5 GHz to deal with loads of data being transferred by the user. However, the 802.11 networking standards alter up to some extents, by the need of the user. Talking about the networks, the 802.11a is going to transmit data at the frequency level of 5 GHz.
Here the OFDM concept is used for improving the data receiving capacity by splitting the radio signal into various smaller components, before meeting the router. One can transmit at most 54 megabits of data in a second through the network. Coming to 802.11b, this transmits data at 2.4 GHz, naturally a slower rate.
Here one can transmit the highest of 11 megabits of data in a second. 802.11g also transmit data at 2.4 GHz but can send the most elevated of 54 megabits of data per second, powered by OFDM coding. Most advanced among these is the 802.11n network that can transmit as much as 140 megabits of data in a second, with a frequency level of 5GHz.
All about Hot Spots
The hotspot is an as frequently spelt term as of Wi-Fi. People immediately look for the hotspot after reaching a restaurant, shopping complex, hotel, etc., if it provides Wi-Fi connectivity. The hotspot is the zone where Wi-Fi access is available. The computer needs to have a wireless adapter for accessing the hotspot facility provided.
Most of the contemporary devices do possess native transmitters for this. For the old models, one may have a wireless adapter, through which one can plug into the PCI or USB slot. There are software’s available as well for hotspot access.
Connect To Wi-Fi through External Modem
One can connect the device to Wi-Fi through a modem as well. For connecting with a wireless router, the first thing to ensure is whether it has been connected with the internet connection point. Activate your external modem prior plugging in the router with the device through Ethernet cable.
Switch on the wireless router to open the browser. Put the IP address, provide a username and set wifi password. Now activate your SSID, and provide the username and password provided by ISP and pick in between WEP and WPA security. Select a new passkey to complete the Wi-Fi configuration.
