The following table shows the standardized UMTS bands and their regional use. The main UMTS bands are in bold print. Networks on UMTS-bands 1 and 8 are suitable for global roaming in ITU Regions 1, 2 (some countries) and 3. Networks on UMTS bands 2 and 4 are suitable for roaming in ITU Region 2 (Americas) only. Networks on UMTS band 5 are ...
For technical details on UMTS and a list of its designated operating frequencies, bands, and their common names, see UMTS frequency bands. Networks on the global UMTS-bands 1 and 8 are suitable for global roaming in ITU Regions 1, 2 (some countries) and 3. Networks on UMTS-bands 2 and 4 allow roaming in ITU Region 2 (Americas) only.
However, it appears as though UMTS is not suffering as much from handset band compatibility issues as GSM did, as many UMTS handsets are multi-band in both UMTS and GSM modes. Penta-band (850, 900, 1700, 2100, and 1900 MHz bands), quad-band GSM (850, 900, 1800, and 1900 MHz bands) and tri-band UMTS (850, 1900, and 2100 MHz bands) handsets are ...
This is a list of commercial Long-Term Evolution (LTE) networks in Asia, grouped by their frequency bands. Some operators use multiple bands and are therefore listed multiple times in respective sections.
UMTS Terrestrial Radio Access Network (UTRAN) is a collective term for the network and equipment that connects mobile handsets to the public telephone network or the Internet. It contains the base stations, which are called Node B 's and Radio Network Controllers (RNCs) [ 1 ] which make up the Universal Mobile Telecommunications System (UMTS ...
It is an acronym for Evolved UMTS Terrestrial Radio Access, [1] also known as the Evolved Universal Terrestrial Radio Access in early drafts of the 3GPP LTE specification. [1] E-UTRAN is the combination of E-UTRA, user equipment (UE), and a Node B (E-UTRAN Node B or Evolved Node B, eNodeB ).
Roaming is one of the fundamental mobility management procedures of all cellular networks.Roaming is defined [2] as the ability for a cellular customer to automatically make and receive voice calls, send and receive data, or access other services, including home data services, when travelling outside the geographical coverage area of the home network, by means of using a visited network.
For technical details on LTE and a list of its designated operating frequencies, bands, and roaming possibilities, see LTE frequency bands. Bands 33 to 44 are assigned to TDD-LTE. Note: This list of network deployments does not imply any widespread deployment or national coverage.
