Seven Things You Didn’t Know About Wi-Fi

Seven Things You Didn’t Know About Wi-Fi

In this digital era of technology where wireless networks play a prominent role in our day-to-day lives, we should always try to keep it secure by various ways like using IP Address. We are adapted to get lured by the new technologies. And now a television, no more needs a device i.e., remote to operate it rather we have a remote-based mobile application where we can directly control it through our smartphones. And as a layman is more interested in learning about the technology, we don’t wholly seem to understand and use it.

Wi-Fi is the wireless technology that connects our digital devices and is now commonplace. As wireless technology is making our lives easier, but there are also facts that we didn’t know about it and the following points discuss the unknown effects of Wi-Fi that we should now know

1. Wi-Fi Uses Radio Waves

The radio waves are electromagnetic radiations which are of different wavelengths and are measured in frequencies. Wi-Fi works on the same principle of other wireless devices, and it sends signals between the devices by using radio waves. The radiofrequency is different from car radios, weather radios, cell phone radio, etc. Wi-Fi transmits and receives data in GHz. And this frequency of Wi-Fi is said to be ranging from 2.4GHz to 5GHz. These frequencies are the same as that of the microwave frequency. Ji

2. Wi-Fi Is Liable To Interference

There is nothing more frustrating than seeing your video buffering while watching an exciting movie. When many devices are connected to the same channel, then the signal weakens. Appliances in our homes are more likely to be susceptible to interference, and the position of the router can also be a cause for intervention. Bluetooth connected devices, cordless phones, and microwaves can be a significant cause for disturbances in signals.

3. Wi-Fi Is Not Fully Secured

Our Wi-Fi networks are only secure when the users are not reckless. With the recent data breach happenings around the world, we should take data privacy seriously. Wi-Fi has been well developed and improved over the times, and it comes with a particular standard security package from the industry so the customer can rely on it blindly. 

Old wireless routers had used simple security protocols, which makes it easy to hack, but the introduction of Wi-Fi had many upgrades in the security protocols. Wireless Equivalent Privacy (WEP) is the first security protocol that was introduced in 1999.

And to secure our Wi-Fi networks, we should change the SSID and default username and also change the password and make sure to maintain the router’s firmware up to date. And also, make sure the devices connected to your network are secure.

4. Wi-Fi Has No Meaning In Its Name

Wi-Fi was initially named as IEEE 802.11 in 1990 when it was first introduced. Wi-Fi does not stand for “Wireless Fidelity“ and is also technically incorrect. Wi-Fi was just designed as a logo and a trademark in 1999 by the Wi-Fi alliance. Wireless Fidelity was just a pun to hi-fi, and so then both results are infidelity. Chairman Phil Balendar said that “Wi-Fi doesn’t stand for anything. It is an acronym. There is no meaning”.

5. Wi-Fi Has A Language Of Its Own

When we speak a language, we follow specific rules, which makes our communication more effective while speaking the same vocabulary. It is the same for machines too. They need a few standards and protocols to be able to communicate with each other, after the release of the standard IEEE 802.11, which was used as a communication medium for wireless networks, then followed by many different versions which have their advantages and disadvantages of their own.

6. Wi-Fi Can Connect Many Devices

Many devices can connect to Wi-Fi, but it also may cause interference. As we already know that the characteristic frequencies of Wi-Fi are 2.4 GHz to 5 GHz, where 5 GHz receives and transmits data faster when compared to 2.4 GHz frequency. Nowadays, most common devices use 2.4 GHz, and it leads to overcrowding, and it weakens the signals and causes interference. So more number of devices connecting to the same network results in slow transmission and receiving of data.

7. Wi-Fi can Travel Very Far

As we saw that frequency is a factor that’s responsible for Wi-Fi speed, but it depends on a few factors like the outputs, the reflection, and the antenna, etc. Commonly used wireless routers transmit radio waves at a range of 100ft approximately, and that gives us a strong signal. The (SSC) Swedish Space Organization transmitted signals over a distance of 310km, and it is said to be the longest transmitted wireless signal.

Wi-Fi was invented 21years ago, and yet it still holds the power of today’s technology. As it is a commonplace everywhere and with its multiple upgrades over the years, we can enjoy a good network. It’s been playing a crucial role in the world of communication and making our lives better. So as the above unknown facts state, let’s enjoy a good network.
