45-智能机项目2射频简介1频段

什么是6模？六模就是支持TD-LTE、FDD-LTE、TD-SCDMA、EVDO&CDMA、WCDMA、GSM六种不同的通信模式，六模和七模的区别CDMA同时包括了CDMA2000（3G）和CDMA 1x（2G）,七模是把CDMA2000（3G）和CDMA 1x（2G）拆分开。常用频段:十三频:TD-LTE Band38/39/40，LTE FDD Band7/3，TD-SCDMA Band34/39，WCDMA Band1/2/5，GSM Band2/3/8。十七频:TDD-LTE Band38/39/40/41，LTE FDD Band1/3/7，TD-SCDMA Band34/39，WCDMA Band1/2/5/8，GSM Band 2/3/5/8。6M - FDD LTE + TDD LTE + WCDMA + TDSCDMA + EVDO + GSM5M -FDD LTE + TDD LTE + WCDMA + EVDO + GSM4M - FDD LTE + TDD LTE + EVDO + GSM全球频段划分及主要运营商对应表3GPP1Generic NameTX_L（MHz）Tx_H（MHz）Rx_L（MHz）Rx_H（MHz）Major OperatorRegionSystemB1WWCore1920198021102170CU,SKT,LGU+,KT,Vodafone，Orange，MTS，CT,KDDI,Docomo，Softbank，worldwideexcept N.America，CanadaUMTS CDMA FDD-LTERev.BB2PCS1850191019301990AT&T,VzW,SprintChina，N.AmericaGSM UMTS CDMAB3DCS1710178518051880CMCC,CU,SKT,LGU+,KT,T-Mobile，Vodafone，Orange，MTSChina，Europe，Korea，S.America,RussiaGSM UMTS FDD-LTEB4AWS-11710175521102155T-Mobile，AT&TN.AmericaUMTSCDMA LTEB5cell824849869894CT,SKT,LGU+,KDDI,Docomo，AT&T,VzWN.America,Australia，Korea，Japan，S.America，ChinaGSM UMTS CDMA Rev.BB6Japancell830840875885rebandedto B19JapanUMTSCDMA Rev.BB72.5GHz2500257026202690TeliaSonera，T-Mobile，Vodafone,CMCCEurope，Russia，HK，SingaporeFDD-LTEB8EGSM880915925960CMCC,CU,Softbank，T-Mobile，Vodafone，Orange，MTSChina，Japan，Korea，Europe，Russia，S.AmericaGSM UMTSB9JapanDCS1750178518451880Docomo，SoftbankJapanUMTS FDD-LTEB10LatAm AWS1710177021102170S.AmericaB11JDCreband1427.91452.91475.91500.9Softbank，KDDIJapanUMTS FDD-LTEB12700lower ABC blocks699716728746USCellularN.AmericaFDD-LTEB13700upper，C block777787746757VzWN.AmericaFDD-LTEB14700upper，D block788798758768USPublic SafetyN.AmericaFDD-LTEB17700lower,BC blocks704716734746AT&T,N.AmericaFDD-LTEB18JapanExtended 850MHz815830860875KDDIJapanFDD-LTEB19Japan850MHz830845875890DocomoJapanUMTS CDMAFDD-LTEB20EuropeanDigital Dividend832862791821T-Mobile，VodafoneEurope，FDD-LTEB21Japan1.5GHz LTE1447.91462.91459.91510.9DocomoJapanFDD-LTEB22Japan3410349035103590DcomoJapanFDD-LTEB23formerlysatellite2000202021802200DishNetworksUSAFDD-LTEB24formerlysatellite1625.51660.515251529LightSquared（declined by FCC)USAonholdB25PCSExtension(G Block）1850191519301995SprintN.AmericaCDMA FDD-LTEB26B5Extension814849859894Sprint，KT,KDDIN.America,Korea，JapanCDMA FDD-LTEB27807824852869NextelB28APAC-700703748758803AsiaFDD-LTEB29700lower DE blocks716728AT&TUSAFDD-LTERxB33EuropeTDD1900192019001920T-mobile，Vodafone，OrangeEuropefallowB34ChinaTD-SCDMA2010202520102025CMCC,MTSChina,RussiaTD-SCDMAB35N.AmericaTDD-LTE1850191018501910N.America（notused）B36N.AmericaTDD-LTE1930199019301990N.America（notused）B37N.AmericaTDD-LTE1910193019101930N.America（notused）B38EuropeHK TDD2570262025702620E2,T-Mobile，VodafoneEuropeTDD-LTEB39ChinaTD-SCDMA1880192018801920CMCCChinaTD-SCDMA,TDD-LTEB40TDWBA2300240023002400CMCC,BhartiChina，Korea，India，AsiaTDD-LTE,WiMAXB412.5GHzTD-LTE2496269024962690CMCC,Softbank，Clearwire（Sprint）China，N.America,JapanTDD-LTEB42TBD3400360034003600various（ex-WiMAX)BritishTelecomTDD-LTEB43TBD3600380036003800various（ex-WiMAX)5M12BFDD_LTE : B1/2/3/4/5/7/17/20 国内用到的1,3,7 ，香港用的B7 B2/4/7/17美国再用， B1/3/7/20欧洲在用, 5M12B很多国家可以用，还要印度，新加坡等。TDD_LTE :B38/39/40/41WCDMA: B1/2/5/8GSM: B2/3/5/8TD-SCDMA:B34/39如果销往国外：那么可以选GSM/WCDMA/FDD_LTE ,那么这就是3M了，TDD_LTE主要是国内用，B39移动的3G和4G，B40也是移动的，B41很多运营商在用，电信，联通，移动也用B41，B41全频道有140M的频点很高频段越高覆盖率越低，移动4G的基站没多远就得有一个。国外（美国）B17，B20低频，覆盖面积很广，就跟FM调频类似，100多M。TDD Bypass机制可以应用在B38/40/41，原理是LTE B38/40/41其中之一工作时，如果同时有2G打开（双通的情况）或WiFi/BT/GPS打开，为降低B38/40/41 TX对它们的干扰，B38/41 TX会走自己的FBAR filter，B40 TX走自己的BAW filter；如果只有LTE B38/40/41其中之一工作，B38/40/41 TX都会走
