Band 2 (PCS 1900MHz)UEs
The LTE band 2 is officially called the PCS (Personal Communication Service) band, and is often referred to as 1900MHz. The PCS band at FDD LTE 60 MHz(1850-1910 and 1930-1990 MHz) is subdivided into six sub-bands, each of which can be used by a different company in each area.
The main advantage of running a mobile phone system in the PCS band is that there is more available spectrum there, so the licenses are easier and cheaper to obtain. The introduction of the PCS band also helped relieve some of the congestion that the 800MHz Cellular systems were experiencing.
