Intersil is sampling its new PRISM WorldRadio (WR) with key customers and leading original design manufacturers (ODMs). The newest member of the PRISM WLAN portfolio is a two-chip, dual-band (2,4 and 5 GHz) solution designed to provide global wireless connectivity. PRISM WR is Intersil's second-generation dual-band WLAN solution (the first being the PRISM Duette chipset).
The PRISM WR enables users to establish a WLAN network connection throughout the world with any standards-compliant wireless 802.11 infrastructure they encounter, including existing and proposed standards - 802.11a, b, d, g, h, i or j. It is capable of tuning frequency ranges that cover the entire worldwide wireless LAN spectrum. PRISM WorldRadio self-configures to the appropriate frequency and operating parameters specific to any region. For instance, in the 5 GHz band, European regions have different and separated WLAN spectrums. PRISM WR fully supports the 2,40-2,50 and 4,9-5,85 GHz frequency ranges with certified dynamic frequency selection (DFS) and transmit power control (TPC) capabilities to ensure non-interference with specified radar operations. PRISM WR also complies with the proposed 802.11j admendment for operation within the 4,9-5,1 GHz band in Japan.
The two-chip solution employ's Intersil's PRISM Nitro technology, a firmware upgrade that is part of Intersil's SingleSource Driver suite. Intersil says that Nitro technology delivers up to a 3x improvement in throughput for 802.11g clients operating in mixed-mode wireless networks and up to 50% greater throughput performance in 802.11a and 802.11g only networks.
Intersil say this second-generation solution also consumes up to 75% less power than competitive designs, allowing users to spend more time connected on battery power.
