B7 (2600 MHz) LTE

O2 Czech Republic uses LTE band B7 (2600 MHz). This frequency band is used for both uplink and downlink operations. The uplink range is from 2500 to 2570 MHz, and the downlink range is from 2620 to 2690 MHz.

Supported LTE Protocols

Name Generation
LTE 4G
LTE-A 4G

5G NR

Name Interface Description
N1 (2100 MHz) 5G NR

O2 Czech Republic uses the 5G NR N1 frequency band, which spans from 1920 to 2170 MHz. This band is commonly referred to as the 2.1 GHz 5G band. The n1 band is known for its excellent range and building penetration due to its propagation characteristics and improved by advanced processing techniques. O2 Czech Republic has deployed this frequency band as part of its 5G network.
N3 (1800 MHz) 5G NR

O2 Czech Republic uses the 5G NR frequency band n3, which covers the 1710 to 1880 MHz range. This band is commonly referred to as the 1.8 GHz band. The n3 band offers excellent coverage and building penetration due to its propagation characteristics. It is also supported by advanced processing techniques. The deployment of this band is part of the broader 5G network rollout in the Czech Republic, which aims to provide high-capacity throughput and support various use cases.
N77 (3700 MHz) 5G NR

O2 Czech Republic uses the 5G NR frequency band n77, which operates around 3700 MHz. This band is known for its relatively common availability and has been historically used in small, adhoc WiMAX and WTTx multipoint networks. The n77 band is popular for its ability to support large channel widths, which are essential for the performance objectives of the 5G standard. Advanced processing techniques such as massive MIMO, beam-forming, and beam-tracking help mitigate the natural limitations of higher frequency propagation. Early n77 networks have used smaller channel widths, but the most popular channel width for fully deployed n77 5G networks is the maximum 100 MHz.
