T-Mobile - United States

T-Mobile United States uses the GSM 1900 MHz (PCS) frequency band for its 2G services. This band operates in the 1,850–1,910 MHz range for the uplink and the 1,930–1,990 MHz range for the downlink. The GSM 1900 MHz band is primarily used in the United States and was introduced in 1995 to support the growing demand for mobile services.

T-Mobile United States uses LTE band 2 (1900 MHz PCS) in its network. This band is primarily used in rural areas or where band 4 is not available, offering higher reach and providing 4G coverage to distant places, especially in the Northeast. It is also used for 2G and 3G services.

T-Mobile United States uses LTE Band 4 (1700/2100 MHz AWS 1) for its network. This band provides a good balance between coverage and capacity, offering decent speeds and reaching a wide area. It is commonly used in urban and suburban areas to support growing data needs and is part of T-Mobile's strategy to deliver reliable coverage and high-speed connectivity to its customers.

T-Mobile United States uses LTE band 12 (700 MHz) for its network. This band is known as "extended range LTE" and is used to provide coverage in rural and suburban areas. It is supported on most phones and offers a reliable connection, especially in remote locations. The deployment of this band began in 2015, with T-Mobile rolling out 700 MHz spectrum in major metro areas to enhance coverage and improve in-building signal strength.

T-Mobile United States uses LTE Band 66 (1700/2100 MHz) to provide a balance between coverage and capacity. This band is part of the mid-frequency spectrum and offers decent speeds, reaching a wide area. It is widely used in urban and suburban environments to support growing data needs.

T-Mobile United States uses frequency band LTE B71, also known as 600 MHz, to enhance its geographic coverage and improve network capacity. This band was deployed in July 2019, following T-Mobile's acquisition of the 600 MHz spectrum. The deployment aimed to increase coverage, especially in rural areas, by leveraging the low-frequency band's ability to travel far and penetrate buildings effectively. The band is used for both 4G LTE and 5G connectivity, with T-Mobile reserving about 50% of the capacity for 5G deployment. The use of Band 71 has significantly improved coverage in various states, such as Wisconsin, Wyoming, and North Dakota, and is expected to continue benefiting users as more devices become compatible with the spectrum.

T-Mobile United States uses LTE Band 5 (850 MHz) for its network. This band operates on the frequency range of 824-849 MHz for the uplink and 869-894 MHz for the downlink. It is primarily used for providing cellular services and supports both 2G and 3G technologies.

T-Mobile United States uses the 5G NR frequency band n41, which operates on a frequency range of 2496-2690 MHz. This band is utilized for both uplink and downlink transmissions and supports Time Division Duplexing (TDD) mode. The n41 band is considered a mid-band frequency, offering a balance between range and capacity. It is particularly used in rural areas to provide better coverage and support more users compared to lower-band frequencies. The higher bandwidth of n41 allows for more efficient use of the spectrum, enabling faster speeds and greater capacity for home internet services in rural locations.

T-Mobile United States uses frequency band 5G NR N71 (600 MHz) for its 5G network. This band is deployed to provide extended range 4G LTE and 5G cellular data, with T-Mobile setting aside about 50% of the total capacity to build out their 5G network. The 600 MHz frequency is known for its ability to travel far from cell towers, making it particularly useful for expanding coverage in remote areas. T-Mobile has been rapidly deploying this band across the United States, including in areas such as Puerto Rico, to enhance network coverage and capacity.

T-Mobile United States uses the 5G NR N260 frequency band, which operates at 39 GHz. This band is part of the mmWave spectrum and is intended for high-speed, short-range transmissions. It offers high capacity and dense frequency reuse, making it suitable for densely populated urban areas and busy venues. The signal, however, does not travel well through obstacles and has limited range, requiring base stations to be placed every few hundred meters to maintain coverage.

T-Mobile United States uses the 5G NR band n261, which operates at 28 GHz. This frequency band is part of the mmWave spectrum and is used for high-speed data transmission. The band spans from 27.5 GHz to 28.35 GHz. T-Mobile has implemented this band to provide fast data speeds, although it is less ideal for mobile phone users who are not stationary due to its limited range and difficulty in penetrating solid objects.

T-Mobile United States uses frequency band 5G NR N258 (mmWave 26 GHz) for its 5G network. This band operates in the 24.25 to 27.5 GHz range and is intended for short-range transmission at high data rates. It is part of the mmWave spectrum, which is known for delivering incredibly fast speeds but having limited range and difficulty penetrating solid objects. T-Mobile has implemented a multi-band spectrum strategy, using low-band to provide wide coverage and mid-band and high-band (Ultra Capacity) to deliver fast speeds, while also testing 5G mmWave on 5G Standalone (5G SA) for crowded areas and potential fixed wireless service applications.
