Today we are discussing about our very important need. What is wifi and how does it works.
Wi-Fi is a wireless LAN that works as one of the useful technologies of computer networking. It actually changed the way of data transfer and communication. Wi-Fi does not actually stand for anything but from the term, we get a sense of local area wireless technology.
WiFi has a lot of advantages. Wireless networks are easy to set up and inexpensive. They’re also unobtrusive — unless you’re on the lookout for a place to watch streaming movies on your tablet, you may not even notice when you’re in a hot spot. In this article, Mytechremedy helps you to look at the technology that allows information to travel over the air.
What is Wi-Fi
Wi-Fi is only a wireless networking technology that allows devices like computers (laptops and desktops), mobile devices (smartphones and wearables etc), and other mostly equipment (printers and video cameras) to interact with the Internet. It makes them allows these devices–and many more–to exchange information with one another, creating a network to share data.
Internet connectivity occurs through a wireless router. When you access Wi-Fi, you are connecting to a wireless router that allows your Wi-Fi-compatible devices to interface with the Internet.
What Do You Think OF Wi-Fi
Wi-Fi is not just an acronym; it is a popular brand name created by a marketing firm that’s meant to serve as an interoperability seal for marketing efforts.
Wi-Fi is just an attractive term used to refer the new technology wireless networks. Previously, there was the only way to connect devices and the way was network cables to create a local area network. It was inconvenient. But Wi-Fi lets one connect one device to another without cables. Without any physical connection, you will get the network. The router mainly controls these connections. One device communicates with another device through the router.
First, let’s cover some of the basics. WiFi stands for Wireless Fidelity and is the same thing as saying WLAN which stands for “Wireless Local Area Network.”
How Wi-Fi Works
Wi-Fi uses their radio waves to transmit all information between our device and a router via frequencies that they had. Two radio-wave frequencies can be used bat a same time, depending on the amount of data being sent: 2.4 gigahertz and 5 gigahertz as frequent. Well, a hertz is just a measurement of frequency which is not our main part. For example, let’s say you’re sitting on a beach, watching the waves crash to shore. If you measured the time between each wave crash equally , you’d be measuring the frequency of the waves. One hertz is a frequency of one wave per second. One gigahertz, on the same other hand, is one billion waves per second, total number of amount.
Every WiFi frequency band has multiple amount of channels within it to so our devices can send and receive data of wifi. The main purpose of the WiFi channels is to decrease interference and overlap between your WiFi device and other WiFi devices. Interference and overlaps can cause your internet speed to slow down. Think of a freeway… If the freeway has one lane, it will get congested very quickly. Now, if the freeway has four lanes, traffic will be able to travel a lot smoother with less congestion resulting in people getting to their destination faster.
WiFi devices automatically access WiFi channels on their own as they can. If you wanted to check which channel you are on, or change the channel, you can use apps like WiFi Overview 360, WiFi Analyzer, or WiFi Router Booster.
How Does WiFi Communicate Between Devices?
WiFi uses thie radio frequencies, or radio waves, to communicate between devices as we used; the frequencies are measured in gigahertz (GHz). WiFi uses their frequency bands 2.4GHz or 5GHz for signal. There arelso a a dual-band devices that let you choose which frequency you want to use for your WiFi network. Difference between frequency is the range and bandwidth they provide. The 2.4 GHz band which will show us WiFi coverage with slower speeds. In contrast, the 5GHz transmits data at a faster speed with less coverage.
Every WiFi frequency band has multiple anpunt of channels including it. to so our devices can send and receive data. The purpose of the WiFi channels is to decrease interference and overlap between your WiFi device and other WiFi devices. Interference and overlaps will cause our internet speed to much slow down. Think of a freeway… If the freeway has only one lane, it will get stucked very quickly. Now, if the freeway has four lanes included, traffic will be able to travel a lot smoother with less congestion resulting in people getting to their destination faster.
How Wi- Fi Works in Three Stpes :
- The modem needs to have a cable or wired connection to access the internet. It depends on the type of internet connection you have at present (i.e. DSL, Dial-Up, Cable) will determine what type of modem will be plugged into.
- The router is connected to the modem as available in range. The router sends out radio waves through its antennas and broadcasts them into your space whe,.re we tries connecting data, allowing multiple devices networking to the internet simultaneously. Without the router, you would need to use ethernet cables as needed to connect the modem and the computer you want to use to access the internet.
- The receivers, which will be in by inserter d by the Wi-Fi cards in the wireless devices, will pick up the two-way radio signal allowing your devices to access the internet as connected.
When Wi-Fi Signal IS weak ?
There are too many gadgets available nowdays that can helps us in boost the signal of our cellular modems are receiving as well. If in any case our Wi-Fi signal finds weak everywhere, a hotspot signal booster like the Hotspot M2M SMA Yagi Antenna Signal Booster and Hotspot M2M SMA Omni Antenna Signal Booster can be used to boost your Wi-Fi signal strength in few minutes. This helps a lot . The Hotspot signal booster will need to be connected to a easier and adjustable modem, and the modem will need to have a cellular antenna port as you can see as a thin stick shape.
