1. 802.11a -  operates in the less crowded 5 GHz frequency band, making it less prone to interference. And its bandwidth is much higher than 802.11b, with a theoretical max of 54 Mbps.
2. 802.11b - range up to 150 feet. 802.11b components are cheap, but the standard has the slowest maximum speed of all the 802.11 standards. And since 802.11b operates in the 2.4 GHz, home appliances or other 2.4 GHz Wi-Fi networks can cause interference.
3. 802.11ac -  5 GHz band, supports up to eight spatial streams (compared with 802.11n’s four streams), doubles the channel width up to 80 MHz, and uses a technology called beamforming. With beamforming, the antennae basically transmit the radio signals so they’re directed at a specific device.
4. 802.11g - operates in the crowded 2.4 GHz (and thus is subject to the same interference issues as 802.11b). 802.11g is backward compatible with 802.11b devices: an 802.11b device can connect to an 802.11g access point (but at 802.11b speeds).
5. 802.11n - - maximum theoretical transfer rate of 300 Mbps (and can reach up to 450 Mbps when using three antennae). 802.11n uses MIMO (Multiple Input Multiple Output) where multiple transmitters/receivers operate simultaneously at one or both ends of the link. This provides a significant increase in data without needing a higher bandwidth or transmit power. 802.11n operates in both the 2.4 GHz and 5 GHz bands
6. Bluetooth - wireless technology standard used for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.400 to 2.485 GHz, and building personal area networks.
7. IEEE 802.11 -  part of the IEEE 802 set of LAN protocols, and specifies the set of media access control and physical layer protocols for implementing wireless local area network Wi-Fi computer communication in various frequencies, including but not limited to 2.4 GHz, 5 GHz, and 60 GHz frequency bands
8. Wi-Fi - a facility allowing computers, smartphones, or other devices to connect to the Internet or communicate with one another wirelessly within a particular area.
9. Wi-Fi Protected Access (WPA) - security standard for users of computing devices equipped with wireless internet connections.
10. Wi-Fi Protected Access 2 (WPA2) -  encryption used to secure the vast majority of Wi-Fi networks.
11. Wi-Fi Protected Setup (WPS) - wireless network security standard that tries to make connections between a router and wireless devices faster and easier.
12. Wired Equivalent Privacy (WEP) -  security algorithm for IEEE 802.11 wireless networks
13. Wireless Access Point (WAP) - communications protocol that is used for wireless data access through most mobile wireless networks
14. Personal Area Network (PAN) -  interconnection of information technology devices within the range of an individual person, typically within a range of 10 meters
15. Extensible Authentication Protocol (EAP) -  authentication framework frequently used in network and internet connections
16. Advanced Encryption Standard (AES)  -  specification for the encryption of electronic data
17. Temporal Key Integrity Protocol (TKIP) - security protocol used in the IEEE 802.11 wireless networking standard
18. Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) - is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle"
19. Infrared Data Association (IrDA) - provides specifications for a complete set of protocols for wireless infrared communications, and the name "IrDA" also refers to that set of protocols
20. Multiuser MIMO (MU-MIMO) -  set of multiple-input and multiple-output technologies for wireless communication, in which a set of users or wireless terminals, each with one or more antennas, communicate with each other
