This is a list of countries by Internet connection speed for average and median data transfer rates for Internet access by end-users. The difference between average and median speeds is the way individual measurements are aggregated.
The channel capacity depends on the physical and electrical properties of the cable, while the wire speed also depends on the connection protocols. The wire speed may also refer to maximum throughput , which typically is a couple of percent lower than the physical layer net bit rate in wired networks due to data-link-layer protocol overhead ...
A wireless configuration utility, [1] wireless configuration tool, [1] wireless LAN client, [citation needed] or wireless connection management utility [citation needed] is a class of network management software that manages the activities and features of a wireless network connection.
A wireless network interface device with a USB interface and internal antenna A Bluetooth interface card. A wireless network interface controller (WNIC) is a network interface controller which connects to a wireless network, such as Wi-Fi, Bluetooth, or LTE (4G) or 5G rather than a wired network, such as an Ethernet network.
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 ...
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. IEEE 802.11 Wi-fi networks are the most widely used wireless networks in the world, connecting devices like laptops (left) to the internet through a wireless router (right).
Anyone within range with a wireless network interface controller can attempt to access a network; because of this, Wi-Fi is more vulnerable to attack (called eavesdropping) than wired networks. Wi-Fi Protected Access (WPA) is a family of technologies created to protect information moving across Wi-Fi networks and includes solutions for personal ...
Two wireless bridge devices may be used to connect two wired networks over a wireless link, useful in situations where a wired connection may be unavailable, such as between two separate homes or for devices that have no wireless networking capability (but have wired networking capability), such as consumer entertainment devices; alternatively ...
