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 ]
Traffic indication map (TIM) is a structure used in 802.11 wireless network management frames. The traffic indication map information element is covered under section 7.3.2.6 of 802.11-1999 standard. [1] The IEEE 802.11 standards use a bitmap to indicate to any sleeping listening stations that the access point (AP) has buffered data waiting for it.
Interviews with IT management and the end users of the wireless network are also important to determine the design parameters for the wireless network. As part of the wireless site survey, the effective range boundary is set, which defines the area over which signal levels needed support the intended application.
Cellular signal strength of -74dBm (or 66 asu) displayed on a smartphone.Also shown: signal bars of two cellular networks, and signal bars of a Wi-Fi network. In telecommunications, received signal strength indicator or received signal strength indication [1] (RSSI) is a measurement of the power present in a received radio signal.
Wi-Fi positioning system (WPS, WiPS or WFPS) is a geolocation system that uses the characteristics of nearby Wi‑Fi access points to discover where a device is located. [1]It is used where satellite navigation such as GPS is inadequate due to various causes including multipath and signal blockage indoors, or where acquiring a satellite fix would take too long.
NetSpot provides all professional wireless site survey features for Wi-Fi and maps coverage of a living area, office space, buildings, etc. [3] It provides visual data to help analyze radio signal leaks, discover noise sources, map channel use, optimize access point locations. Also, the application can perform Wi-Fi network planning: the data ...
