WLAN Solutions: TNETW1130 Converged Single-ChipMAC and Baseband Processor for IEEE 802.11 a/b/g

The single-chip TNETW1130media access controller/basebandprocessor for wireless local areanetworks (WLAN) is a completeand converged solution supportingfull 54 megabits per second(Mbps) data transfer speeds andall 802.11 WLAN standards anddraft standards. The devicefeatures seamless operation in the2.4-GHz and 5.2-GHz bands and isfully compatible with the installedbase of client and access point(AP) WLAN equipment.

TI's TNETW1130 offerscompatibility with the WLANstandards for 802.11a, 802.11band 802.11g draft standards. Thedevice is software upgradeable tobe fully compliant with the802.11g standard once the draftspecification has been approvedas a full standard. In addition, theTNETW1130 supports the recentrefinements to the WLANstandard, addressing issues suchas security- supporting both Wi-FiProtected Access (WPA) as well

as the 802.11i draft standard;Quality of Service (QoS)supporting the 802.11e draftstandard; and global 802.11adeployment-supporting the802.11h draft standard.

The TNETW1130 is one of thefirst WLAN MAC/basebandprocessors to fulfill therequirements of the 802.11security and privacy draftstandard, 802.11i. TheTNETW1130 supports AdvancedEncryption Standard (AES) pluslegacy support for WEP (WiredEquivalency Protocol). As 802.11imandates, the TNETW1130 hashardware accelerators for WPAand the mandatory and optionalimplementations of AES. Furthersecurity enhancements includesupport for LEAP 802.1xauthentication type and additionalforthcoming enhancements for anadditional level of WLAN security.

The TNETW1130 also has aQoS engine for support ofenhanced distributed coordinationfunction (EDCF) and hybridcoordination function (HCF) asspecified in the 802.11e draftstandard. This allows a WLAN todedicate bandwidth for emergingreal-time applications like voice-over-WLAN, broadcast video,video conferencing and others.Additionally, the deviceincorporates transmit powercontrol (TPC), dynamic frequencyselection (DFS) and other

TNETW1130 offers an optional802.11g+ performance increase. Inthis mode, TNETW1130-baseddevices offer an increase inthroughput of up to 50%.

Reference designs based onthe TNETW1130 come in multiplemodes and form factors to meetthe needs of different markets,including 802.11g PC Cards andAPs for home/SOHO networkingkits, 802.11a/g PC Cards forenterprise applications, and802.11a/g mini-PCI cards for PCOEMs. The TNETW1130 can beimplemented in a diverse set ofclient and AP applicationsthrough a broad host of interfacesneeded for 802.11 station and APapplications. These includePCMCIA, Cardbus, PCI, Mini-PCI,USB, Compact Flash and 16-bitgeneric slave.

High-Performance RF andLow Power Consumption

For dual-band 2.4-GHz and 4.9to 5.9-GHz operations supporting802.11b, 802.11g and 802.11a, theTNETW1130 utilizes a high-performance single-chip radiofrequency (RF) solution thatincludes an external power

To facilitate transparentoperations, the TNETW1130 iscapable of seamless and dynamictransition between the establishedWLAN standards for 802.11a and802.11b and the newer, high-speed version of 802.11 in the2.4GHz band, the draft standard802.11g. Drawing on TIs market-proven experience with multi-modulation WLAN technology, theTNETW1130 and theaccompanying system referencedesigns will be able to auto-matically switch between thedifferent transmission modes andfrequency bands, seamlesslysupporting CCK, PBCC and nowOFDM.

Using Auto-Band technology,TNETW1130-based access points(APs) can simultaneously operate,and stations can automaticallyswitch between the differenttransmission modes andfrequency bands, seamlesslysupporting 802.11b, 802.11b+,802.11g, or 802.11a. TheTNETW1130 will enable TIcustomers to offer the first truemultimode products.

For high bandwidth multimediaservices such as video, sharedgaming, audio and voice, the

amplifier (PA). This RF solution iswell suited to low-cost, high-yieldmanufacturing applications.

Like TIs ACX100 andTNETW1100B, the TNETW1130offers higher throughput at longerdistances for 802.11b, 802.11b+(22Mbps), 802.11g, 802.11g+ and802.11a networks leveraging TIsmultipath and receiver technology.For battery-operated and mobileWLAN applications, theTNETW1130 has been optimizedfor low power consumption bytaking advantage of the numerousinnovations TI has pioneered in802.11 standby power modes.With these breakthrough powersaving features, TI providessubstantial power savingscompared to existing solutions.

The TNETW1130 is packagedin a space-saving 16 x 16 mm 257-pin ball grid array (BGA)package, which is pin-for-pincompatible with TIs previousgeneration WLAN MAC/basebandprocessor device.
