The Intersil ISL3886 Wireless LAN Integrated Media Access Controller with Baseband Processor is part of the PRISM Duette™, Dual Band radio chipset. The ISL3886 directly interfaces with Intersil’s ISL3692 Dual Band Direct Conversion transceiver. Adding Intersil’s ISL3092 10GHz VCO and Intersil’s ISL3992 Dual Band Power Amp completes an end-to-end WLAN Chipset solution compliant with 802.11a/b/g/h/i/j standards. The 802.11 protocol is implemented in firmware supporting custom WLAN solutions. Software implements the full IEEE 802.11 Wireless LAN MAC protocol. It supports BSS and IBSS operation under DCF, and operation under the optional Point Coordination Function (PCF). Active scanning is performed autonomously once initiated by host command. Host interface command and status handshakes allow concurrent operations from multi-threaded I/O drivers. Orthogonal Frequency Division Multiplexing (OFDM) of 52 sub-carriers
