Broadcom IC accelerates 802.11n in new routers
Broadcom has added a Wi-Fi Gigabit Ethernet (GbE) processor to its Intensi-fi family of draft-802.11n chips.
Broadcom explained that 802.11n products promise to provide eight times the throughput of the 802.11g version of Wi-Fi, but typically deliver only four-times the rate of 802.11g because of limits imposed by Fast Ethernet switching and network processors.
By integrating a GbE controller and increasing the processor's clock speed in its new IC, Broadcom claims to have eliminated those bottlenecks to approach the theoretical maximum.
In real world tests conducted by the company and validated, Broadcom said, by a third-party testing company, products powered by the new BCM4705 GbE processor produced Wi-Fi throughput in excess of 160 Mbps. Throughput of up to 200 Mbps and higher has been achieved in lab tests.
