REVISION HISTORY
Revision Release Date Summary 0.4 2008/11/26 Preliminary release.
Wireless LAN Network Interface Controller 4 Rev.0.4 1. General Description The Realtek RTL8191SE is a highly integrated single-chip MIMO wireless LAN (WLAN) solution for the wireless high throughput 802.11n draft specification. It co mbines a MAC, a 1T2R capable baseband, and RF in a single chip. The RTL8191SE provides comp lete solution for a high throughput performance wireless client. The RTL8191SE baseband implements multiple input , multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) with 1 transmit and 2 receive paths and is compatible with 802.11n Draft specification 2.0. Other features include one spatia l streams transmission, up to two spatial streams reception, short guard interval (GI) of 400ns, spatial spreading, and transmission over 20 MHz and 40 MHz bandwidth. At the receiver, extended range and good minimum sensitivity is achieved by having receiver diversity up to 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 along with complementary code keying to provide the data rates of 1, 2, 5.5 and 11Mbps 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, provides the ma ximum data rate of 54 Mbps and 300 Mbps for IEEE 802.11g and 802.11n MIMO OFDM respectively. The RTL8191SE builds in an enhanced signal detect or, an adaptive frequency domain equalizer, and a soft-decision Viterbi decoder to alleviate the severe multi-path effects and mutual interference in the reception of multiple streams. For better detection qua lity, receive diversity with maximal-ratio-combine (MRC) applying up to 2 receive paths are implemented. Robust interference detection and suppression are provided to protect against bluetooth, cordless phone, and microwave oven. Receive vector diversity for multi-stream application is implemented for efficient utilization of MIMO channel. Efficient IQ-imbalance, DC offset, phase noise, frequency offset and timing offset compensations are provided for the radio frequency front-end impairments. Selectable digital transmit and receiver FIR filters are provided to meet the requirement of transmit spectrum mask and to reject the adjacent channel interference, respectively. The RTL8191SE supports fast receiver automatic gain control (AGC) with synchronous and asynchronous control loops among antennas, antenna diversity functions, and adaptive transmit power control function to obtain the better performance in the analog portions of the transceiver. The RTL8191SE MAC supports 802.11e for multimedia applications, 802.11i for security, and 802.11n for enhanced MAC protocol efficiency. Using packet aggregation techniques such as A-MPDU with BA and A-MSDU, protocol efficiency is significantly im proved. Power saving mechanisms such as U-APSD, APSD, and MIMO power saving reduces the power wasted during idle time, and compensates for the extra power required to transmit MIMO OFDM. The RTL 8191SE provides simple legacy and 20Mhz/40Mhz co-existence mechanisms to ensure backward and network compatibility.

Wireless LAN Network Interface Controller 15 Rev.0.4 FCC Statement Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. For product available in the USA/Canada market, only channel 1~11 can be operated. Selection of other channels is not possible. This device and its antenna(s) must not be co-located or operation in conjunction with any other antenna or transmitter. FCC NOTICE: To comply with FCC part 15 rules in the United States, the system must be professionally installed to ensure compliance with the Part 15 certification. It is the responsibility of the operator and professional installer to ensure that only certified systems are deployed in the United States. The use of the system in any other combination (such as co-located antennas transmitting the same information) is expressly forbidden. IMPORTANT NOTE: FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. USERS MANUAL OF THE END PRODUCT: In the users manual of the end product, the end user has to be informed to keep at least 20cm separation with the antenna while this end product is installed and operated. The end user has to be informed that the FCC radio-frequency exposure guidelines for an uncontrolled environment can be satisfied. The end user has to also be informed that any changes or modifica tions not expressly approved by the m anufacturer could void the user's authority to operate this equipment. The FCC part 15.19 statement below has to also be available in the manual: This device complies with Part 15 of FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation.
Wireless LAN Network Interface Controller 16 Rev.0.4 LABEL OF THE END PRODUCT: The final end product must be labeled in a visible area with the following " Contains TX FCC ID: TX2-RTL8191SE ". IC Statement Country Code Statement For product available in the USA/Canada market, only channel 1~11 can be operated. Selection of other channels is not possible. This device and its antenna(s) must not be co-located or operation in conjunction with any other antenna or transmitter. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p) is not more than that permitted for successful communication. IMPORTANT NOTE: IC Radiation Exposure Statement: This equipment complies with IC RSS-102 radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. LABEL OF THE END PRODUCT: The final end product must be labeled in a visible area with the following " Contains TX IC: 6317A-RTL8191SE ". This module is intended for OEM integrator. The OEM integrator is still responsible for the IC compliance requirement of the end product, which integrates this module. 20cm minimum distance has to be able to be maintained between the antenna and the users for the host this module is integrated into. Under such configuration, the IC RSS-102 radiation exposure limits set forth for an population/uncontrolled environment can be satisfied. Any changes or modifications not expressly approved by the manufacturer could void the user's authority to operate this equipment. This Class B digital apparatus complies with Canadian ICES-003. Cet appareil numérique de la classe B conforme á la norme NMB-003 du Canada.
