The first products based on M700 will be data devices such as laptop modems, Expresscards and USB modems for notebooks, as well other small-form modems suitable for consumer electronic devices. Commercial release was set for 2009, with products based on the platform expected in 2010. * In November 2008 Motorola demonstrated industry first over-the-air LTE session in 700 MHz spectrum. * Researchers at Nokia Siemens Networks and Heinrich Hertz Institut have demonstrated LTE with 100 Mbit/s Uplink transfer speeds.〔(Researchers demo 100 Mbit/s MIMO with SDMA / virtual MIMO technology )〕 * In December 2008 the "Rel-8" specification was frozen for new features, meaning only essential clarifications and corrections were permitted. * In January 2009 The ASN.1 code was frozen. The Rel-8 standard was complete enough that hardware designers had been designing chipsets, test equipment, and base stations for some time. LTE standards development continues with 3GPP Release 9, which was frozen in December 2009. Updates to all 3GPP specifications are made every quarter and can be found at the 3GPP web site. * At the February 2009 Mobile World Congress: * * Huawei demonstrated the world's first unified frequency-division duplex and time-division duplex (FDD/TDD) LTE solution. * * Aricent gave a demonstration of LTE eNodeB layer2 stacks. * * Setcom streaming a Video 〔(Mr. Markku Niiranen, Setcom Managing Director, Malta )〕 * * Infineon demonstrated a single-chip 65 nm CMOS RF transceiver providing 2G/3G/LTE functionality * * Launch of ng Connect program, a multi-industry consortium founded by Alcatel-Lucent to identify and develop wireless broadband applications. * * Motorola provided LTE drive tour on the streets of Barcelona to demonstrate LTE system performance in a real-life metropolitan RF environment * In July 2009 Nujira demonstrated efficiencies of more than 60% for an 880 MHz LTE Power Amplifier * In August 2009, Nortel and LG Electronics demonstrated the first successful handoff between CDMA and LTE networks in a standards-compliant manner * In August 2009, Alcatel-Lucent receives FCC certification for LTE base stations for the 700 MHz spectrum band. * In September 2009, Nokia Siemens Networks demonstrated world's first LTE call on standards-compliant commercial software. * In October 2009, Ericsson and Samsung demonstrated interoperability between the first ever commercial LTE device and the live network in Stockholm, Sweden. * In October 2009, Alcatel-Lucent's Bell Labs, Deutsche Telekom Laboratories, the Fraunhofer Heinrich-Hertz Institut and antenna supplier Kathrein conducted live field tests of a technology called Coordinated Multipoint Transmission (CoMP) aimed at increasing the data transmission speeds of Long Term Evolution (LTE) and 3G networks. * In November 2009, Alcatel-Lucent completed first live LTE call using 800 MHz spectrum band set aside as part of the European Digital Dividend (EDD). * In November 2009, Nokia Siemens Networks and LG completed first end-to-end interoperability testing of LTE. * On December 14, 2009, the first commercial LTE deployment was in the Scandinavian capitals Stockholm and Oslo by the Swedish-Finnish network operator TeliaSonera and its Norwegian brandname NetCom (Norway). TeliaSonera incorrectly branded the network "4G". The modem devices on offer were manufactured by Samsung (dongle GT-B3710), and the network infrastructure with SingleRAN technology created by Huawei (in Oslo) and Ericsson (in Stockholm). TeliaSonera plans to roll out nationwide LTE across Sweden, Norway and Finland.〔(NetCom.no ) – NetCom 4G (in English)〕 TeliaSonera used spectral bandwidth of 10 MHz (out of the maximum 20 MHz), and Single-Input and Single-Output transmission. The deployment should have provided a physical layer net bitrates of up to 50 Mbit/s downlink and 25 Mbit/s in the uplink. Introductory tests showed a TCP goodput of 42.8 Mbit/s downlink and 5.3 Mbit/s uplink in Stockholm.〔(Daily Mobile Blog )〕 * In December 2009, ST-Ericsson and Ericsson first to achieve LTE and HSPA mobility with a multimode device. * In January 2010, Alcatel-Lucent and LG complete a live handoff of an end-to-end data call between Long Term Evolution (LTE) and CDMA networks. * In February 2010, Nokia Siemens Networks and Vodafone Italy complete the first LTE call in Italy. The test was undertaken with commercial hardware and software. During the call a throughput of about 70 Mbit/s downlink and 19 Mbit/s uplink have been reached. * In February 2010, Nokia Siemens Networks and Movistar test the LTE in Mobile World Congress 2010 in Barcelona, Spain, with both indoor and outdoor demonstrations. * In May 2010, Mobile TeleSystems (MTS) and Huawei showed an indoor LTE network at "Sviaz-Expocomm 2010" in Moscow, Russia. MTS expects to start a trial LTE service in Moscow by the beginning of 2011. Earlier, MTS has received a license to build an LTE network in Uzbekistan, and intends to commence a test LTE network in Ukraine in partnership with Alcatel-Lucent. * At the Shanghai Expo 2010 in May 2010, Motorola demonstrated a live LTE in conjunction with China Mobile. This included video streams and a drive test system using TD-LTE. * In August 2010, Alcatel-Lucent and Texas Energy Network, LLC (TEN), a new startup founded by Gregory M. Casey, former Executive Vice President at Qwest Communications, successfully tested an LTE base station working over a range of 12 km by simulating energy industry video and field operation activity. The tests were conducted within the Permian Basin, in the Artesian area of southeastern New Mexico. * As of 12/10/2010 DirecTV has teamed up with Verizon Wireless for a test of high-speed Long Term Evolution (LTE) wireless technology in a few homes in Pennsylvania, designed to deliver an integrated Internet and TV bundle. Verizon Wireless said it launched LTE wireless services (for data, no voice) in 38 markets where more than 110 million Americans live on Sunday, Dec. 5. * In March 2011, Release 10 specifying LTE Advanced was frozen. * On May 6, 2011, Sri Lanka Telecom Mobitel successfully demonstrated 4G LTE for the first time in South Asia, achieving a data rate of 96 Mbit/s in Sri Lanka.〔 * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「LTE timeline」の詳細全文を読む スポンサード リンク
