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 ]
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 802.11ac-2013. *Wi‑Fi 0, 1, 2, and 3 are named by retroactive inference. 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.
Wireless access point. In computer networking, a wireless access point, or more generally just access point ( AP ), is a networking hardware device that allows other Wi-Fi devices to connect to a wired network or wireless network. As a standalone device, the AP may have a wired or wireless connection to a router or router, but, in a wireless ...
Hirose U.FL. An embedded RouterBoard 112 with U.FL- RSMA pigtail and R52 mini PCI Wi-Fi card. Hirose U.FL, I-PEX MHF I [a], AMC [2] or UMCC [b] is a miniature RF connector for high-frequency signals up to 6 GHz manufactured by Hirose Electric Group, [3] I-PEX, [4] and others. U.FL connectors are commonly used in applications where space is of ...
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
This Linksys WRT54GS, a combined router and Wi‑Fi access point, operates using the 802.11g standard in the 2.4 GHz ISM band using signalling rates up to 54 Mbit/s. For comparison, this Netgear product, a combined router and Wi‑Fi access point from 2013, uses the 802.11ac standard in the 5 GHz band, with signalling rates up to 6933 Mbit/s.
They do not exist in the official nomenclature. [6] [7] [8] IEEE 802.11n-2009, or 802.11n, is a wireless-networking standard that uses multiple antennas to increase data rates. The Wi-Fi Alliance has also retroactively labelled the technology for the standard as Wi-Fi 4. [9] [10] It standardized support for multiple-input multiple-output, frame ...
