What is Wi-Fi? Wi-Fi (Wireless Fidelity) used to connect devices in a network and allow them to transfer information and internet. Based on IEEE 802.11family of standards, with set of protocol. Older version of Wi-Fi device, send or receive data in speed – 11 Mbit/s. Newer version of Wi-Fi device, send or receive data in speed – 11 Gbit/s.
What Does Wi-Fi Stand for? For world changing technology, it needs most unique and marketable name. So Wi-Fi name came from, already famous tool Hi-Fi (High Fidelity).
How Does Wi-Fi Work? Wi-Fi enabled devices communicate with one another by sending and receiving radio waves, they use either the 2.4 GHz or the 5 GHz frequency.
Security Level of Wi-Fi? Wi-Fi routers support various protocols like WPA, WPA2, and WPA3. Which provide a high level of assurance that only authorized users can access their wireless networks. To access Wi-Fi network, authenticate user name and password is required. Using public or free Wi-Fi is highly risk. Because cyber criminals hack your device. So always use trustable Wi-Fi hotspot.
Advantage of Wi-Fi: Wi-Fi has many important advantages over wired connections.
Convenience: Wi-Fi Devices allows n- number of devices to connect to it like PC, mobile, security devices, etc. It also provide Guest logins too. Mobility: With the emergence of public Wi-Fi networks, users can access the internet outside their normal work environment. Most chain coffee shops, for example, offer their customers a Wi-Fi connection to the internet at little or no cost. Productivity: Users connected to Wi-Fi maintain a wide range of speeds as they move from place to place. With increased bandwidth and the right tools on the Internet, staff can collaborate and be engaged much more quickly. Deployment: The installation of Wi-Fi requires little more than a single access point (AP) or antenna connected via a data cable to the business router/switch. Using power over Ethernet (PoE) eliminates the need for an associated power plug. Need for Speed: The speed on most wireless networks (typically 1-54 Mbps) is usually less than wired networks (100Mbps up to several gigabits per second (Gbps)). However, with combo Wi-Fi and wireline networks you can get whatever speed you need whenever you need it. Cost: WiFi and wireline cabling work well together to help you grow, change and adapt your business, bandwidth, and office conditions at an effective price point.
Disadvantages of Wi-Fi Security: Wireless networks may choose to utilize some of the various encryption technologies available. But still it needs more security.
Range: Wi-Fi are sharable for home infrastructure. For wide range, we need to obtain additional range, repeaters or additional access points will have to be purchased. Reliability: Like any radio frequency transmission, wireless networking signals are subject to a wide variety of interference, as well as complex propagation effects that are beyond the control of the network administrator. SPEED: The speed on most wireless networks (typically 1-54 Mbps) is far slower than even the slowest common wired networks (100Mbps up to several Gbps). However, in specialized environments, the throughput of a wired network might be necessary.
Is Wi-Fi Dangerous? The fact that Wi-Fi routers and other devices emit electromagnetic radiation sounds scary, but the fact is that Wi-Fi technology is perfectly safe.
