Automatic Channel Selection (ACS)ĪCS is a feature on the VeeaHub that sets the wireless access points (APs) to the best frequency channel for each, based on a number of metrics that take account of such problems as interference from external wireless sources and the communications with other VeeaHubs in the network.ĪCS is the default option on the VeeaHub, whenever available. This article covers some VeeaHub features that mitigate these problems, Automatic Channel Selection (ACS) and Dynamic Frequency Selection (DFS). In addition, the wireless mesh that connects a VeeaHub network operates on 5GHz, and other proprietary networks may also do so. Radar for aeronautical and weather-forecasting use share the 5GHz range.
#How to scan wifi channels in use Bluetooth
In the 2.4GHz range, interference can include cordless telephones, Bluetooth devices and radiation leakage from other electronics. Some of these wireless ranges are intensively used, as can be seen by the number of SSIDs that nowadays can be detected in any neighborhood, but Wi-Fi is also competing with other uses of the same frequencies. The newer standards also improve transmission by using the available bandwidth more efficiently and changing frequencies automatically to minimise interference. More recently, new Wi-Fi standards have included the 5GHz frequency band, with generally shorter range but higher capacity for data transmission. However, the permitted uses of these frequencies are subject to local regulations that vary across the world, so that all Wi-Fi equipment must be sold using channels within those permitted for the country of sale.Įarly equipment under the Wi-Fi standard was sold using the 2.4GHz frequency band (channels 1 to 11, and up to 13 or 14 depending on the country). It makes use of radio frequencies that are suitable for short-distance communications, and by international agreement are not required to be licensed as (for example) the broadcasting frequencies are.
Wi-Fi (a commercial trademark) is a set of technologies for enabling the sending of data packets across a wireless local area network (WLAN), similar to the use of Ethernet cable in wired LANs.
