600Mbps Wi Fi data transfers by using concurrent use of 2.4 and 5GHz bands by Atheros

Atheros Communications, Inc., a leading developer of advanced wireless solutions, today announced the launch of its highest performance 802.11n solution to date. The AR5008AP-3NX2 chipset’s concurrent operation in the 2.4 GHz and 5 GHz wireless LAN (WLAN) frequency bands delivers up to 600 megabits-per-second (Mbps) aggregate physical data rates and the flexibility to segregate application content into the channels that provide the best user experience…With up to 27 non-overlapping channels, end users can run numerous WLAN applications simultaneously while avoiding interference which often plagues networks operating solely in the 2.4 GHz frequency band. The combined 2.4 and 5 GHz channel capacity supports uninterrupted, jitter-free transmission of multimedia applications.

“Home networks can maximize bandwidth capacity and avoid interference by segregating applications across the two frequency bands. With only three [non-overlapping] channels, the 2.4 GHz band is subject to high levels of congestion from legacy 802.11b/g products and interference from microwave ovens, cordless phones and Bluetooth devices. As such, the 2.4 GHz band is well-suited for applications less sensitive to bandwidth limitations and interference: Internet data traffic, streaming MP3s and wireless printing. The 5 GHz band with 24 channels, fewer legacy devices and virtually no interferers, is ideal for high-bandwidth, latency-sensitive applications that require uninterrupted throughput: HD video streaming, VoIP calls and multi-player online gaming.

“The Microsoft Windows Vista® operating system advocates use of dual-concurrent networks and the allocation of applications onto separate frequency bands based on throughput requirement, latency-sensitivity and interference in the network. In order for retail network routers to earn the Windows Vista Premium Certification logo, they must offer dual-concurrent operation…”
