802.11a/b/g/n USB Stick Adapter
Qualcomm 65-VF438-P2 (MC423D_H) - 802.11a/b/g/n USB Stick Adapter
- FCC ID: J9C-65VF438P2 (FCC Doc) • (http://www.cdmatech.com/)
"701-00232-00" is silkscreened on the board in the FCC photos.
- The shell used by the device would seem to indictate Askey manufacture..
A MAC label w/ a 00:0A:F5 (Airgo) OUI is affixed to the device in the FCC photos.
- It has been assigned to this entry for no reason.
Chipset
- • WFB4130 Single Chip integrated Baseband and MAC
- • WFR4031 Single Chip 2.4/5 GHz 2Tx/3Rx transceiver
M device (alternate model US422D_H) uses Qualcomms WFB400 chipset
- (the successor to Airgos AGN300 chipset). It was likely never publicly released.
Product Description
- Qualcomm 65-VF438-P2 USB stick Adapter design is based on Qualcomm's advanced
- multi-radio WFB4130 Baseband/MAC IC and WFR4031 RF IC, an 802.11a/b/g/n wireless
- LAN solution that sends and receives data at up to 300 Mbps.
- Using Qualcomm’s advanced chipset with patented True MIMO smart antenna technology,
- Qualcomm WFB400-based products provide unprecedented levels of 802.11a/b/g/n range
- and throughput, previously unachievable speed and spectral-efficiency, full Wi-Fi product
- interoperability for 802.11a/b/g/n global regulatory compliance.
Key Features and Benefits
- The fourth generation, Qualcomm’s 802.11n True MIMO chipset, provides the implementer
- of access points, home gateways, WLAN clients, consumer electronics and multimedia
- entertainment, embedded wireless laptop/desktop with the following key features:
- • 802.11a, 802.11b, 802.11g, 802.11n Network Standards
- • MIMO link rates up to 300Mbps
- • 2.4GHz/5GHz Frequency Band Operation
- • Receive Combining and Transmit Diversity
- • Dynamically adjusts between 20/40MHz operation on a frame by frame basis
- • Interoperability with 802.11b/g, 802.11a/b/g , 802.11a/b/g/n
- and 802.11n Draft 1.0 and 2.0 products, 802.11d support
- • 802.11b Long/Short Preamble support on a frame-by-frame basis
- • Transmit rate based power control
