什么是6模?
六模就是支持TD-LTE、FDD-LTE、TD-SCDMA、EVDO&CDMA、WCDMA、GSM六種不同的通信模式, 六模和七模的區(qū)別
CDMA同時包括了CDMA2000(3G)和CDMA 1x(2G),七模是把CDMA2000(3G)和CDMA 1x(2G)拆分開。
6模13頻:
1、2G網(wǎng)絡(luò) GSM:850/900/1800/1900
2、3G網(wǎng)絡(luò)(WCDMA /TD) WCDMA:2100MHz/1900MHz/850MHz(中國聯(lián)通3G) TD-SCDMA:1880-1920MHz/2010-2025MHz(中國移動3G) CDMA2000:1920-1935MHz/2110-2125MHz(中國電信3G)
3、4G網(wǎng)絡(luò) TDD-LTE:1900MHz/2300MHz/2600MHz(中國移動4G) FDD-LTE:1800MHz/2600MHz(中國電信和中國聯(lián)通的4G)
常用頻段: 十三頻:TTD-LTE Band38/39/40,LTE FDD Band7/3,TD-SCDMA Band34/39,WCDMA Band1/2/5,GSM Band2/3/8。
十七頻: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。
