Chinese comms equipment maker ZTE says it is testing ways to boost the performance of LTE by exploring the limits of duplexing technologies.
Swedish networking giant Ericsson has announced the first commercial implementation of FDD/TDD carrier aggregation (CA) on Vodafone’s network in Portugal.
South Korean operator SK Telecom is demonstrating In Band Full Duplex (IBFD), which is being positioned as a potentially key 5G technology, at a tech show in Korea.
The time division flavour of LTE, known as LTE TDD or TD-LTE, once thought to be of primary interest to the Chinese mobile market, is seeing increasingly strong adoption worldwide. Now more than 100 operators are investing in the technology, according to the most recent research from the Global mobile Suppliers Association (GSA).
China’s Ministry of Industry and Information Technology (MIIT) has finally awarded FDD-based 4G licences to smaller carriers China Telecom and China Unicom. The pair, which trail China Mobile, have both received FDD-LTE licences, giving them the opportunity to deploy more universally compatible FDD-LTE technology.
There are now 45 per cent more operators investing in LTE than a year ago, according to the latest report from the Global Mobile Suppliers Association (GSA). The GSA report highlights the continued growth in the technology and the surrounding eco-system since its inception in late 2009. A total of 113 operators have now launched LTE across 51 countries, 77 of which were launched in the past 12 months. Some 195 further networks are in the development stages and 209 networks are forecast to have launched by the end of 2013.
The time division flavour of LTE, LTE-TDD, has gained wide ecosystem acceptance and backing from leading infrastructure and device vendors, leading analyst house Ovum to predict that 25 per cent of all LTE connections will be on LTE TDD by 2016.
The Global TD-LTE Initiative (GTI) was launched at MWC 2011. Founding members were China Mobile, Bharti Airtel, Softbank Mobile, Vodafone, Clearwire, Aero2 and E-Plus.
Altair Semiconductor, a developer of LTE chipsets, has shown off its TD-LTE chipset running at up to 50Mbps on the downlink, and 18Mbps on the uplink. The demonstration was made to China Mobile executives at a Next Generation Mobile Network (NGMN) Alliance board meeting using an AsiaTelco manufactured USB dongle.
The wireless operator community is taking another crack at mobile TV, with a technology that also holds promise for the little used TDD spectrum, which most operators have left gathering spectral dust.
