As of 2019, some versions of Wi-Fi, running on suitable hardware at close range, can achieve speeds of 9.6 Gbit/s ( gigabit per second).Ī 1985 ruling by the U.S. Over time the speed and spectral efficiency of Wi-Fi have increased. Hotspot coverage can be as small as a single room with walls that block radio waves, or as large as many square kilometres (miles) using many overlapping access points with roaming permitted between them. An access point (or hotspot) often has a range of about 20 metres (66 feet) indoors while some modern access points claim up to a 150-metre (490-foot) range outdoors. may greatly reduce range, but this also helps minimize interference between different networks in crowded environments. Many common obstructions such as walls, pillars, home appliances, etc. Wi-Fi's wavebands have relatively high absorption and work best for line-of-sight use. Channels can be shared between networks but only one transmitter can locally transmit on a channel at any moment in time. Wi-Fi most commonly uses the 2.4 gigahertz (120 mm) UHF and 5 gigahertz (60 mm) SHF radio bands these bands are subdivided into multiple channels. The different versions of Wi-Fi are specified by various IEEE 802.11 protocol standards, with the different radio technologies determining radio bands, and the maximum ranges, and speeds that may be achieved. Compatible devices can network through wireless access points to each other as well as to wired devices and the Internet. Wi-Fi uses multiple parts of the IEEE 802 protocol family and is designed to interwork seamlessly with its wired sibling, Ethernet. As of 2019, over 3.05 billion Wi-Fi enabled devices are shipped globally each year. As of 2017, the Wi-Fi Alliance consisted of more than 800 companies from around the world. Wi‑Fi is a trademark of the non-profit Wi-Fi Alliance, which restricts the use of the term Wi-Fi Certified to products that successfully complete interoperability certification testing. These are the most widely used computer networks in the world, used globally in home and small office networks to link desktop and laptop computers, tablet computers, smartphones, smart TVs, printers, and smart speakers together and to a wireless router to connect them to the Internet, and in wireless access points in public places like coffee shops, hotels, libraries and airports to provide the public Internet access for mobile devices. I used the 2b09259647b image.Wi-Fi ( / ˈ w aɪ f aɪ/) is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.

I have got the result and I have no desire to do a source code refactoring. I am sorry for sometimes ugly source code. The goal of this repository is to create a WiFi explore tool for the self educated purpose.
