Wi-Fi is known as Wireless Fidelity. Wi-Fi allows network connectivity through radio signals without the need for wires. "Wi-Fi Alliance" suggesting the term Wi-Fi. Wi-Fi term is also used as a synonym for any type of 802.11 networks.
About Radio Waves
Radio waves are the longest wavelength waves in the electromagnetic spectrum. The length ranges from the size of a football field to the size of a volley ball. Radio waves carry signals to your radio, TV, mobile, etc.
Access Point Defined
Access Point is the configured node on wireless local area network (WLAN). Access points act as a central receiver and transmitter of WLAN radio signals. Access points are dedicated hardware devices, which consist of antenna, radio transmitter, and built-in network adapter.
Hotspot is an area serviced by an access point which allows Wi-Fi clients to connect to a network. Hotspots are those areas where Wi-Fi is provided on demand. Since Wi-Fi has gained acceptance in many businesses, homes, etc, and nowdays most of the laptops and electronic devices are having inbuilt Wi-Fi access devices; Wi-Fi can act as an alternative to a wired LAN. Places like airports, star hotels, cafés, etc, are the locations where Wi-Fi is available on demand. The places where Wi-Fi is available on demand or free are also known as hotspots.
Wi-Fi & Hotspots
The area covered by one or more interconnected Access Points is called a "Hotspot". The space range Hotspots can cover variants from as little as a single room with wireless-opaque walls or as much as many square miles covered by overlapping access points. Wi-Fi can also be used to create a mesh network. Wi-Fi allows connectivity in peer-to-peer mode, which enables devices to connect directly with each other. This connection mode is useful in consumer gaming and electronics applications.
When Wi-Fi technology was first commercialized, there were many problems regarding the interaction between different Wi-Fi gadgets. Then a community called "Wi-Fi Alliance" began to solve this issue, also addressed the needs of the end user, and allowed the technology to mature. The Alliance's "Wi-Fi Certified" stamp on Wi-Fi enabled gadgets assures consumers that the stamped products are interoperable amongst each other. Wi-Fi also enables wireless voice applications (VoWLAN or WVOIP). "Wi-Fi Certified" products interact among each other although their manufacturers are different. A "Wi-Fi" certified product can use any brand of access point with any other point of client hardware which is also "Wi-Fi" certified. Any "Wi-Fi" product will work with any non "Wi-Fi" certified product, if the latter uses the same radio frequency as the former.
SSID & its Purpose
Expansion of SSID is Service Set IDentifier. It is a code that attaches to all packages on a wireless network; only to identify each packet as part of that network. The code consists of case-sensitive alphanumeric characters. Wireless devices that attempt to communicate with each other must share the same SSID. The process of connecting a device to a specific wireless network through …
