The brand name UMB (Ultra Mobile Broadband) was introduced in 2006 as a synonym for this standard. [13] UMB was intended to be a fourth-generation technology, which would make it compete with LTE and WiMAX. These technologies use a high bandwidth, low latency, underlying TCP/IP network with high level services such as voice built on top ...
Ultra Mobile Broadband (UMB) was the brand name for a discontinued 4G project within the 3GPP2 standardization group to improve the CDMA2000 mobile phone standard for next-generation applications and requirements. In November 2008, Qualcomm, UMB's lead sponsor, announced it was ending development of the technology, favoring LTE instead. [17]
In 2011, Argentina's Claro launched a pre-4G HSPA+ network in the country. In 2011, Thailand's Truemove-H launched a pre-4G HSPA+ network with nationwide availability. On March 17, 2011, the HTC Thunderbolt offered by Verizon in the U.S. was the second LTE smartphone to be sold commercially. [60] [61]
As of March 2013, 156 commercial 4G LTE networks existed, including 142 LTE-FDD networks and 14 LTE-TDD networks. [86] As of November 2013, the South Korean government planned to allow a fourth wireless carrier in 2014, which would provide LTE-TDD services, [ 77 ] and in December 2013, LTE-TDD licenses were granted to China's three mobile ...
LTE (Long Term Evolution) is commonly marketed as 4G LTE, but it did not initially meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. Given the competitive pressures of WiMAX and its evolution with Advanced new releases, it has become synonymous with 4G. It was first ...
Ultra Mobile Broadband (UMB) was a 3GPP2 project to develop a fourth-generation successor to CDMA2000. In November 2008, Qualcomm, UMB's lead sponsor, announced it was ending development of the technology, favoring LTE instead. [1]
Initially defined by 4G.IP (a set of companies belonging the telecommunications sector), it was 4G (3rd Generation Partnership Project) who definitively adopted the definition of IMS as a part of the standardization 4G system in networks UMTS (Universal Mobile Telecommunications System), specified in Release 5 and 6.
The following is a list of mobile telecommunications networks using third-generation Universal Mobile Telecommunications System (UMTS) technology. This list does not aim to cover all networks, but instead focuses on networks deployed on frequencies other than 2100 MHz which is commonly deployed around the globe and on Multiband deployments.
