WiFi or Wireless Fidelity was first used commercially in August 1999. 802.11 is the technical code for the WiFi protocol. The term ‘WiFi’ is often used as a synonym for IEEE (Institute of Electrical and Electronics Engineers) 802.11 technology.
Many people, especially techies use WiFi to connect to the Internet. By allowing this access almost everyone can share, communicate and transact business using the net without plugging a single cord.
What equipment is needed?
- Cable or DSL (Digital Subscriber Line) modem
Have a high speed modem for faster internet access.
- Wireless router
A wireless router or WAP ( Wireless Access Point ) acts as a passageway to the main internet access point. It has various ports wherein the modem is plugged in and distributes internet access to multiple users through its antenna.
- Wireless enabled gadgets such as mobile phones and laptops
Latest laptop models have built in wireless cards making it WiFi ready but in older models you would have to use a wireless adapter. This adapter. This adapter emits radio signals that are needed in wireless networking.
How does WiFi work?
To connect to a WiFi netwoe\rk, you must first find a hotspot. A hotspot or service is a location where you can find the strongest WiFi signal. The wireless signal can reach at about 300 feet and lessens as the distance between the router and the electronic device increases.
A WiFi connection functions through a wireless router, which is usually connected to a DSL or cable Internet connection. The router’s antennas will send-off radio signals while the wireless cards or adapters of cellphones, laptops and other similar devices receive it. the router or WAP serves as a bridge that ties a group of wireless devices to a wired Local Area Network, or LAN connection. Once connected, users can freely surf the Internet, play games and share files and information. The process also works in reverse with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer’s wireless adapter.
The average range of a signal is 300 feet. The connection speed slows down as the distance between the computer and the router increases. Walls and other physical barriers present in the area may impede the flow of radio waves.
Why is WiFi essential?
WiFi provides mobility to your life. You can move from one place to another without being disconnected to the network. Plus, you can access the Internet without having too many cables and wires scattered around your workplace or while shopping in the mall.
WiFi is best suited for individuals who are always on-the-go. Since WiFi is gradually becoming ubiquitous, users can already work, be entertained, and be informed everywhere and anytime they please. However, it also has its drawbacks. WiFi network is very sensitive to signal strength that you must ensure all computers and gadgets receive adequate signal strength at all times otherwise, connection will terminate. It is also affected by climatic conditions such as thunderstorms.
