The 802.11_ standard specifies radio frequency ranges between 5.15 and 5.875GHz.Ĩ02.11_ and 802.11_ standards operate in the 2.4 to 2.497GHz range.Ĩ02.11a has a wider frequency band that enables more _s and therefore more data throughput.Ĩ02.11a supports up to _ nonoverlapping channels. Omnidirectional antennas provide wide coverage but weaker signal strength in any one direction than a directional antenna. This type of antenna is used when coverage in all directions from the antenna is required.Ī _ antenna is designed to focus the signal in a particular direction. The rule of thumb is that every _dB of gain added doubles an antenna's effective power output.Īn _ antenna is designed to provide a 360-degree dispersed wave pattern. The _ _ _ is the coverage area of an AP.Īn antenna's _ value is the difference between the 0dBi isotropic and the antenna's power.Ī higher gain value means stronger send and receive signals. The _ _ _ _ is the MAC address of the Basic Service Set (BSS) AP
With an ESS, all APs must use the same ESSID. _ is the network name used with an ESS wireless network design. _ _ _ systems enables clients to roam between areas and maintain the wireless connection without having to reconfigure between BSSs.
The _ _ _ is used to create WLANs or larger wireless networks and is a collection of APs and clients. The BSS is an example of the _ wireless topology. _ _ _ is a wireless network that uses a single AP with one or more wireless clients connecting to the AP. The _ _ _ is a network name needed to connect to a wireless AP. In the _ mode, the AP receives transmissions from wireless devices and transmits those signals to the network.
