Definition WiFi in GeneralsmartphoneWifi itself actually stands for Wireless Fidelity.Usually, so that wifi can be connected to an electronic device, this wifi will use radio wave frequencies in the 2.4GHz to 5GHz range.Along with the times, the internet has changed from what was previously only a tertiary need, which has now become like a primary need.
For that reason, then there are many business people who have sprung up to provide wifi so that their customers can enjoy longer time in their restaurants or cafes.
For wifi frequency problems based on standards from IEEE (Electrical And Electronic Engineers), it is divided into four parts, including:
•802.11b 11 Mb/s 2.4 GHz B
•802.11g 54 Mb/s 2.4 GHz B, G
•802.11a 54 Mb/s 5 GHz A
•802.11n 100 Mb/s 2.4 GHz B, G, N
Type “b” is the first wifi product. Meanwhile, the “g” and “n” types were one of the products that had the most sales in demand by the public in 2005.
Based on its physical form, wifi is divided into two parts, including:
PCI form
USB Format
This type of PCI is generally used in a PC (personal computer).
While the USB type is more portable, which can be used on a laptop or PC. This is because it is designed with a USB plug type. This will make it easier for every user.
Understanding Wifi According to Experts
The following are some definitions of wifi according to experts, including:
- Onno W. Purbo
Wifi is a standard that is often used as a communication tool on wireless networks.
Which is the basis of the IEEE specification. In general, this wireless network is used or shared together in a particular room or community.
- Priyambodo
Wifi is a standard of a network without using cables or also known as Wireless Networking which functions as a complement to various components in the internet network so that it can be connected or so that it can be connected to the internet more practically and easily.
- Yuhezir
Wifi is a device that stands for Wireless Fidelity. That is a standard device that is used to communicate locally without having to use a cable as a hook.
- Doni Kurniawan
Definition of Wifi or network without using a cable according to Doni is an old technology which in its application has been found in the Pentium 3 netbook.
And then, the application of this one technology must be connected or applied to the pentium 4 netbook and also the next generation.
Or in other words, a wireless network is a network that comes from the latest technology that must exist in every generation of netbooks. It is intended that the development of this technology can be more developed and advanced.
- Jubile Interprise
According to Jubile, Wi-Fi is the latest variant of information and communication technology which then works on a network and Wireless Local Network (WLAN) devices.
WiFi History
The following is a brief history of the development of wifi, including:
1997: Formed a wireless network named 802.11 by the IEEE (Institute of Electrical and Electronics Engineers)1999: The emergence of Wireless B which has a data transfer rate of up to 11 Mbps. But it still has a weakness, namely where the operating frequency is at 2.4 GHz, which is also widely used by the frequency of household appliances such as microwave ovens, so the signal is easily disturbed.2003: The advent of Wireless G with a maximum data transfer rate of up to 54 Mbps. It can still operate at a frequency of 2.4 GHz.2009: The emergence of Wireless N which supports data transfer rates up to 300 Mbps (2 antennas) or 450 Mbps (3 antennas). This network has a wider access range than the Wireless G signal.2014: The emergence of Wireless AC which has a speed of 500Mb/s – 1 Gb/s. And operates at a frequency of 5 GHz.
Benefits of WiFi
The following are some of the common benefits of wifi, including:
- To share files and folders
By utilizing the wifi network, connected devices can easily exchange data and files securely.
- To connect with the internet
By using wifi, you can share internet access more easily and practically. So that to be able to connect to the internet, each user or user is enough to turn on the wifi device that is already available on the device.
- Sync mobile without USB
By using wifi, then you can connect your cellphone to a laptop more easily without using a USB or cable.
You just need to activate wireless on your mobile device.
- Transferring videos and photos from a digital camera
By using a wifi network, after taking videos or pictures, you can directly send the results on your laptop as long as you are still connected to wifi.
- Printing on a printer
By using a wifi network, you can also print data more easily from a laptop to a printer that already has a wifi network.
Apart from the above benefits, there are also several other benefits such as:
- Save Cost
Using wifi can save costs because you don’t need to buy a lot of cables. This is what companies and people who have more ownership use to build wifi.
Especially for laptop and smartphone users and also workers who use the internet who use wifi a lot for various purposes.
Because if you use cellular data, of course, it will cost a lot.
- Accessibility
By using wifi, you can access the internet network at a more stable and practical speed without using cables.
And of course it can be connected anywhere and anytime as long as it is still within the hotspot range.
