UMTS B2 (1900 MHz PCS)
UMTS B2 (1900 MHz PCS) is a frequency band used by Universal Mobile Telecommunications System (UMTS) networks. Here is a summary of its key characteristics:
- Frequency Range: 1850 MHz to 1910 MHz for the uplink and 1930 MHz to 1990 MHz for the downlink.
- Duplex Spacing: 80 MHz.
- Common Name: PCS (Personal Communication Services).
- Channel Bandwidths: Commonly used bandwidths include 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, and 20 MHz.
- Deployment: This band is widely used in the Americas, particularly in the United States, for both 3G and 4G networks. It is also used for global roaming in ITU Regions 2 and 3.
- Technical Characteristics: The band is allocated for UMTS-FDD (Frequency Division Duplex) technology and is used for both uplink and downlink transmissions. It is a key band for T-Mobile in the United States, where it has been "refarmed" for LTE use in many markets.
