Collection: DCS 1805-1880MHz Cell Communication Signal
The basic system of DCS1800 MHZ is exactly the same as that of the existing GSM900 system, but it works in the 1800 MHz frequency band and requires a GSM 1800 mobile phone. If you use a dual-band mobile phone, you can also roam and switch automatically in the G network. In many cities, the DCS1800 system and the GSM900 system cover an area at the same time, which is called the GSM dual-frequency system, which doubles the capacity of the GSM mobile communication system.
DCS 1800MHZ is mostly used for radio signal transmission, and many radio enthusiasts will use this frequency band.
