.11 Wireless Technology Overview The IEEE standard.11 wireless technology, also known as Wi-Fi, has been widely popular for wireless networking and has set the bar for users' expectations with other wireless technologies. Wi-Fi technology has the advantage of reaching great distances, typically a range of around 100ft IEEE 802.11ac-2013 is an amendment to IEEE 802.11, published in December 2013, that builds on 802.11n. The 802.11ac standard was retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance. Changes compared to 802.11n include wider channels (80 or 160 MHz versus 40 MHz) in the 5 GHz band, more spatial streams (up to eight versus four), higher-order modulation (up to 256-QAM vs. 64-QAM), and the. The Wireless local area network (WLAN) protocol, IEEE 802.11, and associated technologies, such as the 802.11X protocol, allow secure high-speed wireless network access and mobile access to a network infrastructure
There are a number of different technologies used to communicate over 802.11 networks. One big difference between different standards of 802.11 networks are the frequencies used to communicate. Some 802.11 networks use the 2.4 gigahertz frequency range. Other 802.11 technologies will use the 5 gigahertz frequency range In this paper, we review and summarize one of the emerging wireless broadband technology i.e. IEEE 802.11,which is a set of physical layer standard for implementing wireless local area network..
Because 802.11ax technology is such a significant paradigm shift from previous versions of 802.11 technology, it has been bestowed with the generational name of Wi-Fi 6. 802.11ax and Wi-Fi 6 mean the same thing. Still, the term Wi-Fi 6 will be more prevalent with the general population IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the 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. The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance
The IEEE 802.11™ standards family, the core technology behind Wi-Fi®, has continually been modified and enhanced to meet industry demands for robust and reliable wireless connectivity. A recently approved project, IEEE 802.11bf ™ for WLAN sensing, holds promise for making even greater use of 802.11 technology IEEE 802 Network Technology Family Tree. 802.11 is a member of the IEEE 802 family, which is a series of specifications for local area network (LAN) technologies.

802.11n is an IEEE (Institute of Electrical and Electronics Engineers) industry standard for local Wi-Fi network communications, ratified in 2009. It replaced older 802.11a, 802.11b, and 802.11g Wi-Fi technologies but was superseded by the 802.11ac in 2013 and 802.11ax (Wi-Fi 6) in 2019. 802.11ay (Wi-Fi 7) is up next Technology Advantages. PRODIGY 2.0™ can also enable a temporary and encrypted Wi-Fi interface that allows the user to maintain the wireless radio using a 802.11-compatible device like a laptop or a smartphone. We designed this feature to avoid pole climbing to reconfigure and troubleshoot a device mounted on top of a tower IEEE 802.15.4, IEEE 802.11, and other network technologies will play a fundamental role in enabling such integrated environment. The IEEE 802.15.4 coexistence with other 2.4 GHz wireless networks in medical environments has been studied in [ 15 , 60 , 66 - 69 ] FHSS, DSSS, OFDM, and 802.11 Standards. The original 802.11 standard had two variations, both offering the same speeds but differing in the RF spread spectrum used. One of the 802.11 standards used FHSS. This 802.11 variant used the 2.4GHz radio frequency band and operated at a 1 or 2Mbps data rate
In this section, we will look at several networking technologies: 802.2, 802.3, 802.5, 802.11, and FDDI. Each of these is just a standard set of technologies, each with its own characteristics. 802.2 Logical Link Control The technical definition for 802.2 is the standard for the upper Data Link Layer sublayer also known as the Logical Link.

WIRELESS-N (802.11n) is the previous generation of wireless networking technology - prior to 802.11ac. 802.11n enables speeds up to 300Mbps and is backward compatible with 802.11g & 802.11b. 802.11n built upon the previous 802.11G standard by adding two new technologies The next-generation 802.11ax Wi-Fi standard, also known as Wi-Fi 6, is the latest step in a journey of nonstop innovation. The standard builds on the strengths of 802.11ac, adding efficiency, flexibility, and scalability that allows new and existing networks increased speed and capacity with next-generation applications
The idea, according to the WiFi Alliance, is to make matching endpoint and router capabilities a simpler matter for the rank-and-file user of WiFi technology. Meanwhile it's important to know that the Wi-Fi Alliance has not made up simpler names for all the 802.11 standards, so it's important to be familiar with the traditional designations Brief History and Overview of 802.11 Standards. It's important to note that the official IEEE standard for wireless Local Area Network (LAN) communication is known as 802.11 with various sub-naming designations such as 802.11b, 802.11g, 802.11n, 802.11ac etc.. The term Wi-Fi is simply the marketing (trademark) name which encompasses all of the above technical standard terms from IEEE. With 160 MHz channel bonding (as opposed to 80 Mhz bonding over wave 1) and backwards compatibility with previous standards, the new standard boasts a performance boost over the first generation of 802.11ac routers. With a physical link rate of nearly 7 Gbps, users hoping to upgrade to 802.11ac should consider waiting to catch the second wave D. d.

An extension to the 802.11 standard developed by the IEEE for wireless network technology. 802.11b applies to wireless local area networks and supports a maximum connect rate of 11 Mbps with fallback to 5.5, 2, and 1 Mbps in the 2.4GHz ISM band. This standard was ratified in 1999 While various 802.11 standards have varying range and susceptibility to noise, modern peer-to-peer network technologies in the 802.11 space can suffer from a single point of failure. Specifically, peer-to-peer networks utilizing the Wi-Fi Alliance (WFA) Wi-Fi Direct technology will fail if the device designated as the Group Owner (GO) withdraws. Highlights: Wi-Fi 6 is the most recent iteration of the Wi-Fi network protocol and is a substantial upgrade over its predecessor. Wi-Fi 6 can be faster due to technologies like traffic prioritization, OFDMA, and beamforming. This new protocol is also more secure and uses new encryption technologies such as SAE Previously, 802.11 transmissions were transmitted using 20 MHz data channels. Anyone who has deployed an 802.11a/b/g AP has worked with 20 MHz channels, with each AP set to a single, non-overlapping channel. With 802.11n, two channels can be bonded, which actually more than doubles the bandwidth because the guard channels in between also are used

A basic service set (BSS) is the cornerstone topology of any 802.11 network.The communicating devices that make up a BSS consist of one access point radio with one or more client stations. Wi-Fi 6 radios are able to differentiate between BSSs using a BSS color identifier when other radios transmit on the same channel. If the color is the same, this is considered to be an intra-BSS frame. We first review IEEE 802.11/WLAN and IEEE 802.16/WiMAX technologies, and make a comparison between IEEE 802.11/WLAN and IEEE 802.16/WiMAX. Then some open research issues in the integrated IEEE 802.16/WiMAX and IEEE 802.11/WLAN networks are discussed, especially regarding QoS support, radio resource management, scheduling and connection.
The extremely low price of IEEE 802.11 components, the use of the license-free 2.4GHz/5.8GHz ISM bands and our previous experience with WiFi-based wide area networks allow us to propose this technology as an appropriated solution for these scenarios. It is important to remark that IEEE 802.11 technology has been designed for indoor environments
