Quad band is a device feature that supports four different frequency bands used in communication: 850 MHz, 900 MHz, 1,800 MHz and 1,900 MHz . In the context of mobile phones, a quad band feature gives the user wider roaming capabilities.

Read moreWhat frequency is UMTS?
Networks in this region are commonly deployed on 850 MHz (Band 5) and/or 1900 MHz (Band 2) unless denoted otherwise.
Read moreWhat does ARFCN stand for?
In GSM cellular networks, an absolute radio-frequency channel number (ARFCN) is a code that specifies a pair of physical radio carriers used for transmission and reception in a land mobile radio system, one for the uplink signal and one for the downlink signal.
Read moreWhat is uplink and downlink frequency?
Uplink frequency is the frequency at which, the first earth station is communicating with satellite . The satellite transponder converts this signal into another frequency and sends it down to the second earth station. This frequency is called as Downlink frequency.
Read moreWhat is DL and UL frequency?
In case of FDD (Frequency Division Duplex) LTE downlink channel (DL, eNB transmits UEs receive) and uplink channel (UL, UEs transmit eNB receives) are transmitted simultaneously on different frequencies . Also each band is marked by LTE release number where it was defined.
Read moreWhy uplink and downlink frequency are not same in satellite?
It’s because lower frequencies get reflected by atmospheric bands and cannot penetrate to get through to the satellite . … Therefore, mobile-to-base station (uplink) frequencies are lower than base station-to-mobile(downlink) frequencies.
