ESCRIPTION
UGWDR82NUH50A USB dongle
The UGWDR82NUH50A USB dongle features the Realtek RTL8191SU which integrates IEEE 802.11
b/g/n RF transceiver, baseband and MAC layer. The USB dongle supports the 1TX/2RX MIMO
antenna technology to support 300Mbps downstream and 150Mbps upstream PHY rates. The USB
dongle is a self powered USB device utilizing the 5V power source supplied by VBUS. A host controller
is required to support the full 802.11 protocol and driver. Embedded Linux and WinCE driver support
is available.
Realtek RTL8191SU IC
The Realtek RTL8191SU-GR is a highly integrated MIMO (Multiple In, Multiple Out) Wireless LAN
(WLAN) USB 2.0 network interface controller complying with the IEEE 802.11n Draft specification 2.0
and IEEE 802.11n Final specification 1.0. It combines a MAC, 1T2R capable baseband and RF in a
single chip, the RTL8191SU-GR provides a complete solution for a high-performance wireless client.
The RTL8191SU-GR baseband implements MIMO Orthogonal Frequency Division Multiplexing (OFDM)
with one transmit and two receive paths (1T2R). Features include one spatial stream transmissions,
short Guard Interval (GI) of 400ns, spatial spreading, and support for both 20MHz and 40MHz
channel bandwidth. The RTL8191SU-GR provides spatial stream Space-Time Block Code (STBC) to
extend transmission range. As a receiver, extended range and good minimum sensitivity is achieved
by having receiver diversity via 2 antennas.
For legacy compatibility, Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying
(CCK) and OFDM baseband processing are included to support all IEEE 802.11b, and 802.11g data
rates. Differential phase shift keying modulation schemes, DBPSK and DQPSK with data scrambling
capability are available, and CCK provides support for legacy data rates, with long or short preamble.
The high speed FFT/IFFT paths, combined with BPSK, QPSK, 16QAM, and 64QAM modulation of the
individual subcarriers, and rate compatible punctured convolutional coding with coding rate of 1/2,
2/3, 3/4, and 5/6, provide the higher data rates of 54Mbps and 300Mbps for IEEE 802.11g and
802.11n MIMO OFDM respectively.
