900 MHz (E-GSM) GSM

A1 Croatia uses the GSM 900 MHz (E-GSM) frequency band. This band operates at 880.0–915.0 MHz for the uplink and 925.0–960.0 MHz for the downlink. The deployment of GSM 900 MHz (E-GSM) in Croatia began in 1991, when mobile services based on GSM were first launched in Finland and subsequently expanded to other European countries, including Croatia.

UMTS

Name Interface Description
B1 (2100 MHz) UMTS

A1 Croatia uses the UMTS frequency band B1 (2100 MHz). This band was deployed in Croatia.

LTE

Name Interface Description
B3 (1800 MHz +) LTE

A1 Croatia uses the LTE B3 (1800 MHz +) frequency band. The deployment date for this band is not specified.
B7 (2600 MHz) LTE

A1 Croatia uses LTE band B7 (2600 MHz). The deployment of this band is not specified.
B20 (800 MHz DD) LTE

A1 Croatia uses LTE B20 (800 MHz DD) for its LTE network deployments. This frequency band is particularly known for its wide area coverage and deep penetration, making it suitable for regional and rural environments, as well as in-building coverage. It supports carrier aggregation with other bands to enhance bandwidth and performance.

5G NR

Name Interface Description
N28 (700 MHz) 5G NR

A1 Croatia uses the 5G NR frequency band n28 (700 MHz) for its 5G network. The deployment of this frequency band is not specified in the provided information.
N77 (3700 MHz) 5G NR
