What Is Tri-Band Technology?
"Tri-band" includes three operating frequencies. These three operating frequencies are GSM900Mhz, DCS1800Mhz, and PCS1900Mhz, and so on. The so-called "tri-band mobile phone" means that the mobile phone can receive three frequency bands: GSM900Mhz, DCS1800Mhz, and PCS1900Mhz. Choose a signal from that. If the signal in that frequency band is strong, then select the signal in that base station. If one party cannot connect, you can freely switch to the signal in the other frequency band.

- "Tri-band" includes three operating frequencies. These three operating frequencies are GSM900Mhz, DCS1800Mhz, and PCS1900Mhz, and so on. The so-called "tri-band mobile phone" means that the mobile phone can simultaneously receive the three frequency bands of GSM900Mhz, DCS1800Mhz, and PCS1900Mhz. Choose a signal from that. If the signal in that frequency band is strong, then select the signal in that base station. If one party cannot connect, you can freely switch to the signal in the other frequency band.
- It actually expands the connection rate of mobile phones. In some regions where mobile phone users are concentrated, it is particularly suitable to use tri-band mobile phones, because tri-band mobile phones can flexibly switch between GSM900, DCS1800, and PCS1900 in order to maintain constant call quality and call quality. PCS1900 trillion network, is a network segment commonly used in North America (United States, Canada) and European countries in the field of communication networks.
- Since tri-band mobile phones can work in three different frequency network segments at the same time, tri-band mobile phones undoubtedly have the characteristics of these three networks. From a technical point of view, GSM1800's high frequency band makes signal penetration strong, so it can bring good call quality and communication coverage in a complex environment with high buildings. The PCS1900 channel is used in North America (United States, Canada) and The European region has good communication capabilities, which undoubtedly provides those who frequently travel between intercontinentals with the services they need.
- For operators, the construction of a tri-band network has completely alleviated the problems of the frequency band and capacity of the GSM900, further optimized the network, effectively alleviated the peak traffic volume in hot areas, and achieved a higher connection rate. Greatly increase business volume.
