Netw. The International Journal of Wireless Information Networks is a quarterly peer-reviewed scientific journal covering research on wireless networks, including sensor networks, mobile ad hoc networks, wireless personal area networks, wireless LANs, indoor positioning systems, wireless health, body area networking, cyber-physical systems, and ...
Antennas. Wi-Fi ( / ˈwaɪfaɪ /) [1] [a] 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. These are the most widely used computer networks, used globally in ...
IEEE 802.11s is a wireless local area network (WLAN) standard and an IEEE 802.11 amendment for mesh networking, defining how wireless devices can interconnect to create a wireless LAN mesh network, which may be used for relatively fixed (not mobile) topologies and wireless ad hoc networks. The IEEE 802.11s task group drew upon volunteers from ...
Wireless icon. A wireless network is a computer network that uses wireless data connections between network nodes. [1] Wireless networking allows homes, telecommunications networks and business installations to avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.

Network standard: ISO/IEC 13157 etc. was IEEE 802.15.1; now by SIG specs Topology Point-to-point Wireless personal area network (WPAN) Cryptography Not with RFID Available Range < 20 cm ≈100 m (class 1) ≈50 m Frequency 13.56 MHz 2.4–2.5 GHz Bit rate 424 kbit/s 2.1 Mbit/s 1 Mbit/s Set-up time < 0.1 s < 6 s < 0.006 s Current consumption
Some of these technologies include standards such as ANT UWB, Bluetooth, Zigbee, and Wireless USB . Wireless Sensor Networks (WSN / WSAN) are, generically, networks of low-power, low-cost devices that interconnect wirelessly to collect, exchange, and sometimes act-on data collected from their physical environments - "sensor networks".
Wi-Fi Protected Access ( WPA ), Wi-Fi Protected Access 2 ( WPA2 ), and Wi-Fi Protected Access 3 ( WPA3) are the three security certification programs developed after 2000 by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found in the previous system, Wired ...
802.11 frame types. In the IEEE 802.11 wireless LAN protocols (such as Wi-Fi ), a MAC frame is constructed of common fields (which are present in all types of frames) and specific fields (present in certain cases, depending on the type and subtype specified in the first octet of the frame). The very first two octets transmitted by a station are ...
