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.
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 ...
The Universal Mobile Telecommunications System (UMTS) is a 3G mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology.
In 3G, the most prevalent technology was UMTS with CDMA-2000 in close contention. All radio access technologies have to solve the same problems: to divide the finite RF spectrum among multiple users as efficiently as possible. GSM uses TDMA and FDMA for user and cell separation. UMTS, IS-95 and CDMA-2000 use CDMA. WiMAX and LTE use OFDM.
A point-to-point dedicated channel for transmitting user traffic information between a UE and the network. UL/DL 5.3.1.1.1 [4] 3_LOGICAL PCCH: paging control channel Transfers paging information. Used when the network does not know the location cell of the UE or the UE is in sleep mode. DL 5.3.1.1.1 [4] 2_TRANSPORT BCH: broadcast channel
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 ...
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.
