LTE B2 (1900 MHz PCS)
The LTE B2 (1900 MHz PCS) frequency band is a key component of 4G LTE networks, particularly in the United States. Here is a summary of its characteristics and usage:
Technical Characteristics
- Duplex Spacing: 80 MHz
- Uplink Start: 1850 MHz
- Uplink Stop: 1910 MHz
- UL ARFCN Low: 18600
- UL ARFCN High: 19199
- Downlink Start: 1930 MHz
- Downlink Stop: 1990 MHz
- DL ARFCN Low: 600
- DL ARFCN High: 1199
Geographical Band Usage
- Global Deployment: Limited due to overlap with Band 1 (2100 MHz), representing fewer than 4% of all commercial LTE networks globally.
- US Deployment:
- AT&T: Core band used in most markets, often deployed in 20x20 MHz blocks.
- Verizon: Used in rural areas or where Band 4 is not available, with higher reach and significant deployment in the Northeast.
- T-Mobile: Owned since Voicestream years, refarmed for LTE use, with common bandwidths of 5, 10, 15, and 20 MHz.
Notes
- The band is often used in rural areas due to its higher reach and ability to travel through walls better than other bands.
- It is also used in urban areas as a supplement to other bands for improved capacity.
Overall, LTE B2 (1900 MHz PCS) is a critical band for 4G LTE networks, particularly in the United States, offering a balance between coverage and capacity in both rural and urban settings.
