Can Hackers Access Your Personal Data Through A WiFi
Wi-Fi is the wireless technology that allows computers, tablets, cellphones, and other devices to connect to the internet. Wi-Fi is a radio signal transmitted from a wireless router to a nearby device, which converts the signal into data that you can see and use.
How Does Wi-Fi Communicate Between Devices?
Wi-Fi communicates between devices by using radio frequencies, or radio waves; the frequencies are measured in gigahertz (GHz). WiFi signals use frequency bands 2.4GHz or 5GHz. Dual-band devices allow you to select the frequency you want to utilize for your WiFi network. The distinction between the frequency bands is the range and bandwidth they provide. The 2.4 GHz band offers more WiFi coverage but at a slower speed. 5GHz, on the other hand, transfers data at a quicker rate but with less coverage.
Each WiFi frequency band contains many channels that allow our devices to send and receive data. The WiFi channels' aim is to reduce interference and overlap between your WiFi device and other WiFi devices. Interference and overlaps might slow down your internet speed. Consider a freeway... If the motorway only one lane, it will get congested very rapidly. If the motorway has four lanes, traffic will be able to go much more smoothly and with less congestion, allowing passengers to get at their destination faster.
WiFi devices automatically access WiFi channels on their own. Apps such as WiFi Overview 360 and WiFi Analyzer can help you determine which channel you are on and modify it.
How Do WiFi Devices Connect?
With developments in wireless technology, gadgets such as PCs, cellphones, smart TVs, and so on now have a wireless adapter. The wireless adapter is a component of the hardware known as a WiFi card. The WiFi card detects radio frequencies and allows the devices to connect to wireless internet.
The frequency and speed of your device will be determined by the IEEE 802.11 standard under which it is certified.
How Does WiFi Function?
WiFi requires either a modem linked to a wireless router or a wireless gateway, which is a modem and wireless router combined. These are your wireless access points, which are hubs that generate wireless signals and allow wireless devices to connect to the internet.
Nowadays, routers are frequently WiFi 6 capable and backwards compatible with WiFi 5. XDual band technology allows you to work on two frequencies at the same time, resulting in faster speeds and more reliable signal.

Tips for Using Free Wi-Fi
The internet has become the most crucial aspect of cellphones. You cannot use any app without this. To save data, more individuals often live in the jugaad of free Wi-Fi. There is now free Wi-Fi available in many public venues. In such cases, people connect to the internet and begin using their phones.

It has been observed that many times, scammers leave the Wi-Fi password unprotected. This enables others to quickly connect with him. When you connect your smartphone to that Wi-Fi, the hackers gain access to your phone's MAC address and IP address. Following then, your data will be sent in the form of packets. Hackers intercept these packets and check your browsing history. Apart from this, they also easily intercept visible traffic by resorting to network sniffing. After this your data can easily go to them.
You can keep yourself secure if you keep these points in mind.
- Connect to any Wi-Fi network that does not have a password.
- Even if you are utilizing public Wi-Fi, bear in mind that you should never do banking transactions during this period. In the event of a hack, hackers will have access to your bank and will be able to break into your account.
- When using public Wi-Fi, turn off all phone sharing.
