Was bringt der "Afterburner"?

Beitragvon Eric » 07.01.2006 13:26

Hi,

ich ja gern mal gewusst, was die Einstellung "Afterburner" bei meinem WLan-Adapter (Broadcom 802.11g) bringt.
Im Urzustand wer er deaktiviert, habe ihn mal angestellt?
Hat irgendjemand Erfahrungen gemacht?

lol...

war das jetzt ein witz? (afterburner lol)

edit: ok.. war kein witz.. hab kurz gesucht

soweit ich das verstanden habe: ist ne neue wlan technologie die anscheinend "schneller" sein soll.. damit "übertaktest" du dein wlan.. 0_o

Broadcom to Give Wireless Networks Zip

Source: Matthew Broersma, ZDNet (UK)

Broadcom has introduced a Wi-Fi chipset that it says can speed the performance of 802.11g networks to 125mbps, potentially creating new opportunities for routing high-bandwidth media across wireless networks.

The company's 54g MaxPerformance chipset, with AfterBurner technology, is designed to be compatible with existing 802.11g networks, with an added "performance" mode that offers the equivalent to a signal rate of 125mbps, Broadcom said Thursday at the Consumer Electronics Show in Las Vegas. That is faster than other wireless-LAN acceleration technologies, such as Atheros' 108mbps Super G.
"Broadcom's latest offering provides both 802.11g compliance and a performance mode that can significantly increase throughput in an 802.11g-capable network," said Broadcom Senior Director Jeff Abramowitz in a statement.

The first product using AfterBurner, Buffalo Technology's AirStation 125mbps Wireless Cable/DSL Router-g (WHR2-G54), also made its debut Thursday. The four-port broadband router combines WLAN acceleration with a system called AirStation One-Touch Secure System (AOSS), designed to simplify wireless security configuration.

Broadcom said that the performance gain in AfterBurner is due to the closing down of the timing between data packets. The chipset uses one 802.11g channel for transmission, unlike Super G, which multiplexes traffic over two channels--an approach that Broadcom claims causes interference with other devices using the 2.4GHz radio band, including Wi-Fi and Bluetooth devices.

"Unlike competing high-speed solutions, the WHR2-G54 does not cause harm to nearby 2.4GHz wireless systems," said Buffalo in a statement.

Broadcom's chipset is currently being demonstrated at CES. The WHR2-G54 will be on the market in the United States next month for $199 (£108). Broadcom supplies WLAN chips to networking equipment makers such as Belkin, Linksys, Microsoft and Motorola; and its chips are used in notebook PCs from Apple Computer, Dell, eMachines, Fujitsu, Gateway and Hewlett-Packard.

Broadcom has shipped more than 11 million of its 54g chipsets, and it controls 78 percent of the U.S. retail market for 802.11g products, according to figures from the NPD Group released Thursday.
Multimedia networks

AfterBurner underscores a recent trend among chipmakers to create ever-faster networks for transmitting larger forms of digital media. The goal is to create wireless networks that can support forms of digital media that require greater bandwidth, such as video.

For example, on Tuesday NetGear announced the Super G-based WGT634U Super Wireless Media Router, which connects to an external hard drive over a USB 2.0 connection and allows client devices on the router's Wi-Fi network to access the drive's contents.

Earlier this week, chipmaker GlobespanVirata announced the Prism Nitro XM Xtreme Multimedia, an upgrade for its 802.11g, 802.11a and combination 802.11g/802.11a chips that boosts wireless transfer rates for compressed data to up to 140mbps, though actual throughput rates will be about 70mbps.
Globespan Virata's system only speeds up the transfer of compressed data, such as audio and video, while content, such as encrypted data, is transferred at lower speeds.

The wireless-networking industry has been working on networks with higher throughputs, and industry groups such as the Institute of Electrical and Electronics Engineers are getting the ball rolling on the next Wi-Fi standard, 802.11n, which is expected to offer an actual transfer rate of more than 100mbps. That standard is not expected to be finished for several years.

Nee das war kein Scherz.
Und Bluetoothkompatibel ist es auch noch?
(--> siehe Bild)

Oder bin ich naiv...?

Damit ist höchstwahrscheinlich gemeint das es Bluetooth nicht behindert, da beide auf ähnlichen Frequenzen arbeiten.
Kompatibel im Sinne von nutzbar ist es aber auf keinen Fall, da beide völlig andere Verfahren für die Verbindung nutzen.
(WLAN belegt sehr große Frequenz Bereiche statisch, Bluetooth nutzt kleine Frequenzbereiche und dynamisches Frequenz Hopping.
