Following are the drawbacks or disadvantages of WiFi: ➨Data transfer rate decreases (to individual computer) when number of clients or computers connected with wifi network increases. ➨Full security is difficult to achieve due to wifi connection being wireless in nature.
Advantages of Wifi

Should wifi be everywhere (and free)? Yes, wifi should be like air and it shouldn't cost the consumer anything to use it. There should be limits put on it, perhaps throttling if users start to download movies or access torrent sites. But basic wireless internet access should be free in public places.

Follow the steps below for how to set up free WiFi for customers.
- Choose a reliable ISP.
- Choose a high-speed, high-bandwidth service plan.
- Get and set up the appropriate equipment.
- Set up a guest network.
- Set up a captive portal.
- Prevent bandwidth hogging.
- Communicate the WiFi password to customers.
Free public WiFi contributes to a better connected society and more agile interactions between citizens and business. Any mayor or government authority implementing this public service would see its popularity boosted immediately. Tourists and visitors in business trips would also find their stay more pleasant.
Easier Collaboration
Using Wi-Fi at school, students can quickly and easily share documents, edit presentations in real time, store project files in the cloud, and improve their teamwork skills. Wi-Fi in education even allows students to collaborate with peers from other schools.WIFI: Wireless Fidelity
WIFI also Spelled as Wi-Fi is a local area wireless technology. It allows an electronic device to transfer data or connect to the internet using ISM radio bands. It is an underlying technology of wireless local area network (WLAN).Wi-Fi is defined as an abbreviation for wireless fidelity, meaning you can access or connect to a network using radio waves, without needing to use wires. An example of Wi-Fi is when you go to Starbucks and can join on their network to get on the Internet without having to connect your computer to any wires.
Wi-Fi lets you connect one device to another without the cables. You still get the network, but not the physical connections. That's a wireless local network—and it's separate from the Internet. To get to the Internet, you need to connect that router to an Internet source, such as a broadband modem.
Positive Impact of wifi on our life • Wifi has made things quicker and easier, which is what our society craves. We can communicate more efficiently from almost everywhere. Wifi is convenient to use and users can use it from nearly any convenient location.
Wireless connectivity, also known as Wi-Fi, uses radio signals to transmit data from one device to another. Wi-Fi is a trademarked term of a company that stands for IEEE 802.11x Standards. The term Wi-Fi (pronounced “Why-Fy”) was coined by the company because of its similarity to then popular term 'Hi-Fi'.
Buy a Portable Router
Instead of being connected to the internet via a cable, they have a slot for a SIM card, allowing you to connect to 3G and 4G networks practically anywhere in the world. Once connected, a portable router can create a WiFi network, so you can connect all your electronic devices to the internet.Create WiFi Zone
- Connect one more LAN cable to the router under output segment where the other point must be connected to the desktop/laptop Switch on both the devices now.
- To set-up the connection, one must select Username and password in the setup settings of the router.
- To set-up, the same, type the IP address: 192.168.
Your private information is just that: private. So the next time you log into the supposedly “free” WiFi network as you commute to work on the subway, keep in mind that just as there is no such thing as a free lunch, there is no such thing as “free” WiFi.
4) WiFi Uses Radio Waves
Your laptop/tablet/etc. uses a wireless adapter to translate data into a radio signal and transmit that signal using an antenna. Those radio waves emanate outwards from the antenna and are received by your wireless router. At a high level this is how all wireless communication works.Use Facebook "Find WiFi"
Open the Facebook app, which you're sure to have already downloaded, tap the More tab and open up "Find WiFi" with your iPhone or Android device. This feature will help you find nearby sources of free, public Wi-Fi.What is Community Wi-Fi? Community Wi-Fi networks allow service providers to leverage unused capacity on existing Wi-Fi infrastructure to offer Wi-Fi network access to visitors and passers by. An operator can also use this excess capacity to offer services to retail and roaming–partner operators' subscribers.
A municipal wireless network is a citywide wireless network. This usually works by providing municipal broadband via Wi-Fi to large parts or all of a municipal area by deploying a wireless mesh network. The typical deployment design uses hundreds of wireless access points deployed outdoors, often on poles.
3G follows a pattern of G's that the ITU started in the early 1990s. The pattern is a wireless initiative called the International Mobile Communications 2000. 3G, therefore, comes just after 2G and 2.5G, the second-generation technologies. 2G technologies include, among others, the Global System for Mobile.
Unfortunately, hotel WiFi networks — even ones that seem to diligently check your guest credentials before allowing you to connect — are not any safer than other public WiFi and should be treated with the same caution as any hotspot you might encounter at a coffee shop or airport.
WiFi Hotspots. Many public spaces such as restaurants and retail stores now offer WiFi as a free service to customers. A WiFi hotspot is simply an area with an accessible wireless network. The term is most often used to refer to wireless networks in public areas like airports and coffee shops.
Even if it requires a password to login, that doesn't necessarily mean your online activities are safe. You might love public Wi-Fi, but so do hackers! So, if you use public Wi-Fi without adequate protection, you're essentially risking your online identity and money.
People claim that Wi-Fi routers keep them awake at night, cause cancer, cause hyperactivity in children, and all manner of unsupported and nonsensical claims.
Legit WiFi hosted at the airport is still susceptible to the same threats as any public WiFi. There are still sniffers intercepting unencrypted information and grabbing access credentials when they can, even from the hoity-toity “private” WiFi networks of the airline lounges.
Wifi hotspots are places where you can find wifi, free or paid. You can log on to free wifi at hotspots where wifi is intentionally offered to the public without charge; some wifi networks are protected with passwords and you must pay or otherwise be given access to log on.
Why Using a Public Wi-Fi Network Can Be Dangerous, Even When Accessing Encrypted Websites. There are a few big problems with using a public Wi-Fi network. The open nature of the network allows for snooping, the network could be full of compromised machines, or — most worryingly — the hotspot itself could be malicious.
An unsecure network most often refers to a free Wi-Fi (wireless) network, like at a coffeehouse or retail store. It means there's no special login or screening process to get on the network, which means you and anyone else can use it.
Which of the following should you NOT do to secure a wireless network? Implement media access control. Create a security encryption passphrase. Disable SSID broadcasting.
