May 06, 2017

According to the communication standard, the base station antenna can be divided into 2G standard GSM, CDMA antenna, 3G standard WCDMA, CDMA2000, TD-SCDMA antenna, 4G standard FDD-LTE, TDD-LTE antenna and the above multi- Port antenna. In general, only work in a standard antenna for the narrow band antenna, work in two standard for the wideband antenna, work in the three standard above known as ultra wideband antenna. Under normal circumstances, a variety of standard antenna operating frequency band is different, each country assigned the standard work frequency band is generally not the same. China's base station antenna frequency band specific allocation as follows: 2G antenna: GSM, 900 / 1800MHz; CDMA, 800MHz. 3G antenna: CDMA2000 & WCDMA, 2100MHz; TD-SCDMA, 1880-1920,2010-2025,2320-2370MHz; 4G antenna: TDD-LTE, 2320-2370,2570-2620MHz; FDD-LTE, band planning has not yet clear.
