For wider area communications, wireless local area network (WLAN) is used. WLANs are often known by their commercial product name Wi-Fi. These systems are used to provide wireless access to other systems on the local network such as other computers, shared printers, and other such devices or even the internet.
This is a list of countries by Internet connection speed for average and median data transfer rates for Internet access by end-users. The difference between average and median speeds is the way individual measurements are aggregated.
This standard aims to boost data speed (throughput-per-area [e]) in crowded places like offices and malls. Though the nominal data rate is only 37% [ 12 ] better than 802.11ac, the total network speed increases by 300%, [ 13 ] making it more efficient and reducing latency by 75%. [ 14 ]
Since a cell is allocated a group of frequency carries (e.g. f 1-f 7) for each user, this range of frequencies is the bandwidth of that cell, BW. If that cell covers an area A c, and each user has bandwidth B then the number of channels will be BW/B.
IEEE 802.15.4 protocol stack. Devices are designed to interact with each other over a conceptually simple wireless network.The definition of the network layers is based on the OSI model; although only the lower layers are defined in the standard, interaction with upper layers is intended, possibly using an IEEE 802.2 logical link control sublayer accessing the MAC through a convergence sublayer.
To increase data rate, 802.11n added optional support for a 0.4 μs guard interval. This provides an 11% increase in data rate. This provides an 11% increase in data rate. To increase coverage area, IEEE 802.11ax (Wi-Fi 6) provides optional support for 0.8 μs , 1.6 μs , and 3.2 μs guard intervals.
IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. [e] The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance. [9] [10]
Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access. Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [ 1 ]
