Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks . It operates in the 2.4 GHz and 5 GHz bands, [ 9 ] with an extended version, Wi-Fi 6E , that adds the 6 GHz band. [ 10 ]
Nodes typically connect in a star or mesh topology. While most individual nodes in a WSAN are expected to have limited range (Bluetooth, Zigbee, 6LoWPAN, etc.), particular nodes may be capable of more expansive communications (Wi-Fi, Cellular networks, etc.) and any individual WSAN can span a wide geographical range. An example of a WSAN would ...
A Wi-Fi device is a short-range wireless device. Wi-Fi devices are fabricated on RF CMOS integrated circuit chips. [127] Since the early 2000s, manufacturers are building wireless network adapters into most laptops. The price of chipsets for Wi-Fi continues to drop, making it an economical networking option included in ever more devices. [128]
The DoD IPv6 Standards Profiles for IPv6 Capable Products (DoD IPv6 Profile) is the singular “IPv6 Capable” definition in DoD. It is a document that lists the six agreed upon product classes (Host, Router, Layer 3 Switch, Network Appliance, Security Device, and Advanced Server) and their corresponding standards (RFCs).
Wi-Fi Aware is an interoperability certification program announced in January 2015 that enables device users, when in the range of a particular access point or another compatible device, to receive notifications of applications or services available in the proximity.
The DSSS method used by legacy 802.11 and 802.11b (and the 11b-compatible rates of 11 g) use 22 MHz of bandwidth. This is from the 11 MHz chip rate used by the coding system. No guard band is prescribed; [16] the channel definition provides 3 MHz between 1, 6, and 11. The OFDM method used by 802.11a/g/n occupies a bandwidth of 16.25 MHz.
