T-Mobile - Germany

T-Mobile Germany uses the GSM 900 MHz (E-GSM) frequency band. This band was deployed in 1992 as part of Germany's first GSM 900 MHz frequency cellular network, referred to as D-Netz.

T-Mobile Germany uses the GSM 1800 MHz (DCS) frequency band for its mobile communications. This band is used for both mobile transmit and base station transmit frequencies. The GSM 1800 band is allocated between 1710 – 1785 MHz for mobile transmit and between 1805 – 1880 MHz for base station transmit. This band is widely used in Europe and other parts of the world, including Africa and Asia, for GSM services.

T-Mobile Germany uses LTE Band 3 (1800 MHz +) for its LTE deployments. This frequency band is widely utilized globally, particularly in Europe, APAC, MEA, and selected countries in South America, facilitating international roaming for mobile broadband services. It supports both FDD (Frequency Division Duplex) and TDD (Time Division Duplex) configurations, offering a balance between network coverage and data capacity, making it suitable for dense urban areas.

T-Mobile Germany uses the LTE frequency band around 2600 MHz. This frequency band was deployed in Germany since the end of 2010.

T-Mobile Germany 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 is also popular for IoT applications like eMTC (LTE Cat M1) and NB-IoT (LTE Cat NB1) due to its wide coverage characteristics. The 800 MHz band does not easily support Massive MIMO and beamforming technologies due to its large wavelength. It can be used as a single band or as part of a multi-band network, and it supports carrier aggregation with other bands to enhance bandwidth and performance.

T-Mobile Germany does not use LTE band B1 (2100 MHz).

T-Mobile Germany uses the LTE B8 (900 MHz) frequency band for both 2G GSM and 4G LTE mobile communications. This band was initially used for GSM 900 MHz frequency cellular networks, which began operating in 1992. The LTE B8 band was later adopted for 4G LTE services.

T-Mobile Germany uses LTE Band 28, also known as the 700 MHz APT band, for its 4G LTE network. This frequency band operates between 703 MHz and 803 MHz, with a duplex mode of Full-Duplex Frequency Division Duplex (FDD). The uplink frequency range is 703–748 MHz, and the downlink frequency range is 758–803 MHz. The band supports channel bandwidths of 5, 10, 15, and 20 MHz. It is widely used by public mobile operators for LTE network deployments due to its excellent propagation characteristics, which allow signals to penetrate buildings and cover larger geographic areas with less infrastructure.

T-Mobile Germany uses LTE band B32, which operates at 1500 MHz. This band is part of the L-band frequency range.

T-Mobile Germany uses the 5G NR frequency band n1, which operates at 2100 MHz. This band is commonly referred to as the 2.1 GHz band. The deployment of this frequency band is part of T-Mobile's broader strategy to provide 5G services across Germany, leveraging the existing infrastructure and spectrum allocation. The use of the 2.1 GHz band allows for good coverage and penetration in various environments, making it suitable for both rural and urban areas.

T-Mobile Germany uses the 5G NR N3 frequency band, which covers the 1710 to 1880 MHz range. This band is commonly referred to as the 1.8 GHz 5G band. The n3 band is popular due to its widespread availability and use in 3G and 4G networks. Operators may "re-farm" existing 3G networks on these frequencies to repurpose them for 5G networks. The n3 band offers excellent range and building penetration due to its propagation characteristics and improved by advanced processing techniques.

T-Mobile Germany uses the 5G NR frequency band N77, which operates at 3700 MHz. This band is part of the C-band 5G spectrum. The deployment of this band is expected to occur in 2024, as announced by T-Mobile. The use of this band is intended to enhance network capacity and speed, particularly in densely populated regions where the shorter wavelength of the 3.6 GHz frequency offers advantages in terms of data throughput and coverage.

T-Mobile Germany uses the 5G NR N78 (3500 MHz) frequency band for its 5G deployments. This band operates in the 3300 to 3800 MHz range and is particularly popular for its ability to support large channel widths, making it suitable for delivering high-capacity 5G services. The band is designated for Time Division Duplexing (TDD) and is widely used for 5G due to its relatively common availability and potential for high capacity throughput. Advanced technologies like massive MIMO, beam-forming, and beam-tracking help mitigate the limited range and building penetration issues associated with higher frequencies. The most popular channel width for fully deployed n78 5G networks is the maximum 100 MHz.
