Therefore, it is not recommended for more than 2-3 wireless clients to use frame-bursting as the negative effects can adversely affect the throughput for all clients. Proprietary extensions that have added frame bursting to the wireless standards include Nitro from Intersil, Super G from Atheros, Xpress from Broadcom and Xtreme G from D-Link. [3]
802.11 Beacon frame. A beacon frame is a type of management frame in IEEE 802.11 WLANs. It contains information about the network. Beacon frames are transmitted periodically; they serve to announce the presence of a wireless LAN and to provide a timing signal to synchronise communications with the devices using the network (the members of a service set).
Xpress technology is Broadcom's standards-based frame-bursting approach to improve 802.11 wireless LAN performance. It is a software-based implementation of the frame-bursting originally in the IEEE 802.11e draft specification, and is found in the Wireless Multimedia Extensions (WME) specification.
Timing synchronization is achieved by stations periodically exchanging timing information through beacon frames. In (intra) BSS, the AP sends the TSF information in the beacons. In Independent Basic Service Set (IBSS, ad-hoc), each station competes to send the beacon. Each station maintains a TSF timer counting in increments of microseconds (μs).
Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LANs, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar , satellite communication , and weather radar , and also to provide on aggregate a ...
Light tubes (also known as solar pipes, tubular skylights or sun tunnels [1]) are structures that transmit or distribute natural or artificial light for the purpose of illumination and are examples of optical waveguides. In their application to daylighting, they are also often called tubular daylighting devices, sun pipes, sun scopes, or ...
