B28n Tt Youtube Band 28 is an lte operating frequency band. lte is designed to work across a number of frequency bands – e utra operating bands currently ranging from 450 mhz up to 3.8ghz. the available bandwidths are also flexible starting with 1.4 mhz up to 20 mhz with carrier aggregation allowing use of wider multiples. 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。 6模13频: 1、2g网络. gsm:850 900 1800 1900. 2、3g网络 (wcdma td) wcdma:2100mhz 1900mhz 850mhz(中国联通3g) td scdma:1880 1920mhz 2010 2025mhz(中国移动3g) cdma2000:1920 1935mhz 2110 2125mhz(中国电信3g) 3、4g网络. B28 band is an lte frequency division duplexing (fdd) band split into 703 to 748 mhz 758 to 803 mhz. in some applications the b28 band is implemented as b28a (703 to 733 mhz 758 to 788 mhz) and b28b (718 to 748 mhz 773 803 mhz). Lte has been developed to operate on paired spectrum for frequency division duplex (fdd), and unpaired spectrum for time division duplex (tdd). for an lte radio system to facilitate bidirectional communication, it is necessary to implement a duplex scheme so that a device may transmit and receive without collision.

Before you buy a sim card, check the supported operators and gsm wcdma frequency in the following table. note: 2g gsm network has been shut down in some countries and more and more operators plan to phase out gsm network. it's wise to check with your local operator for gsm support and sunset plan. 台湾地区有五家运营商:中华电信,台湾大哥大,远传电信,台湾之星,亚太电信,4g频段包括b1,b3,b7,b8,b28,b38……除中华和台星以外的三家都用b28做4g主力和volte,所以去台湾玩,买中华电信的卡吧。 欧洲主要频段比国内多了b20,亚太地区是b28。 水货手机基本不支持电信cdma和移动td scdma,也很少支持b39,通常只能完美支持联通,比如 htc 10的骁龙820国际版。 最后切记买水货手机不要买卡贴机或者有锁机。 1.目前国内4g全频全网通手机通常支持: fdd lte:b1、b3、b5、b7、b8; td lte:b34、b38、b39、b40、b41 (2555~2655mhz);. 有4个lte频段,分别为: band 1、 band 3、 band 7、 band 28。 澳大利亚共有3个主要运营商(不含虚拟运营商),分别为: optus、 telstra、 vodafone。 有2个gsm频段,分别为: dcs1800、 egsm900。.
