T-Mobile Czechia

The company provides 2G GSM services over the 900 and 1800 MHz bands, and launched 3G UMTS3G UMTS: UMTS is an umbrella term for the third generation radio technologies developed by the 3GPP. UMTS specifies a complete network system, for which the radio access component, known as UTRAN, uses WCDMA technology to offer greater spectral efficiency and bandwidth to mobile network… over B1 (2100 MHz) in January 2008 which it upgraded to HSPA+ in November 2008, and later to DC-HSPA+ in April 2012. The network has since been refarmed to 4G LTE4G LTE: 4G LTE (Long Term Evolution) or the E-UTRAN (Evolved Universal Terrestrial Access Network), introduced in 3GPP Rel. 8, is the radio access component of the Evolved Packet System (EPS) - a purely IP based mobile network standard. As an evolution to 3G UMTS, 4G LTE shares many similarities, such as….

In July 2014 T-Mobile launched the first Czech LTE-A services, combining 20 MHz of B3 (1800 MHz) with 10 MHz of B20 (800 MHz) to achieve peak downlink data rates of 225 Mbps. B1 (2100 MHz) was added to the LTE-A mix in December 2015, using 3C aggregation to increase peak data rates to 375 Mbps. February 2016 saw the introduction of B7 (2600 MHz) with a 20 MHz channel.

In March 2017 T-Mobile announced the introduction of fixed LTE to provide up to 100 Mbps connections to previously unreachable locations. The company is working with HuaweiHuawei: Huawei stands as a premier global provider of information and communications technology (ICT) solutions. The overarching goal is to enhance life and boost efficiency via a more interconnected world, whilst embodying a responsible corporate citizen, an innovative catalyst for the information society… to implement 4X4 MIMO on its FWA network, as well as testing Massive MIMOMassive MIMO: A wireless communication architecture that uses a large number of antennas (often denoted as 'massive' due to the scale, typically in the order of tens or even hundreds) at the transmitter and receiver to facilitate multiple simultaneous data streams. Massive MIMO uses techniques like beamforming,… on its mobile network.

As part of its IoT strategy, in September 2015 T-Mobile announced a partnership with SimpleCell Networks to deploy a nationwide Sigfox IoT network, however this was later abandoned. In December 2017 the company announced the launch of its NB-IoTNB-IoT: Narrowband IoT (NB-IoT) is a 3GPP Release 13 feature that reuses various principles and building blocks of the LTE physical layer and higher protocol layers and defines a new Cat-NB1 UE. The standard leverages a mobile operator's existing LTE base stations permitting rapid time-to… network in Prague, and to be progressively expanded outwards.

The company launched its 5G network in November 2020, initially using n1 and n3 as DSS bands, but later adding a dedicated n28 (700 MHz) band in September 2021.
