WiFi BLE Combo Mini PCIe Card QCA AR9462 WB222 11an 2.4 5GHz

Description

WB222 is a WiFi BLE Combo Mini PCIe Module based on Qualcomm^R AR9462 which is a single chip with 2.4 / 5GHz dual bands 802.11 a/b/g/n and BT 4.0.

The AR9462 is a single-chip solution that combines dual-bands (2.4/5 GHz), 2-stream 802.11a/n and BT 4.0 for notebooks, netbooks and tablets. The highly integrated solution provides customers with greater design flexibility, and highly improves the wireless experience for consumers.
The AR9462 brings Qualcomm XSPAN’s industry-leading 2×2 802.11n performance to increasingly smaller computing and CE devices. The data rates is 300 Mbps in 2×2 mode. With unique set of advanced 11n technologies known as Signal-Sustain Technology™ (SST), which ensures stronger wireless connections across the entire WLAN link. SST features include Low Density Parity Checking (LDPC), Maximum Ratio Combining (MRC) and Maximum Likelihood Demodulation (MLD) – which together can increase rate-over-range performance by up to 100% at short range, 50% at mid-range and 25% at long range.

Qualcomm offers a robust platform that streamlines the design of wireless devices. AR9462 is upstream-compatible with Android and Chrome OS. Microsoft software is available for Windows 10/8/7, Vista, and XP. The chip offers a PCIe interface for WLAN, and Qualcomm’s DirectConnect™ technology offers Wi-Fi Direct CERTIFIED support for P2P applications. In its Fast Channel Switch (FCS) feature, the channel switching time is reduced to as little as 1 ms in single band and to 2ms in between the 2.4 GHz and 5 GHz bands.

AR9462 integrates several external components, including the 2.4 GHz and 5 GHz Low Noise Amplifiers and Power Amplifiers, switching regulators, and the WLAN and Bluetooth EEPROMs. This can dramatically reducte the RBOM of a standard PCIe Half Mini Card by up to 45%, relative to discrete 2×2 dual-band and Bluetooth combination solutions.
