BROWSING: FDD

Use of advanced modulation is a first for FDD, partners say Samsung Networks and Qualcomm have used advanced modulation as defined in 3GPP Release 17 to boost downlink speeds by about 20% compared to the use of 256 QAM. The lab test, conducts at Samsung's research...

Deploying massive MIMO for mid-band 5G presents the opportunity to massively reduce per site power consumption and system-level energy efficiency While there isn’t anything magical that happens when a new year starts, it does represent the opportunity to renew focus, refresh ambition and revisit priorities....

Dish recorded 200 Mbps uplink peak speeds with 35 MHz of 5G spectrum and 1.3 Gbps downlink peak speeds with 75 MHz of 5G spectrum Dish Wireless this week announced the successful completion of simultaneous 5G 2x uplink and 4x downlink carrier aggregation (CA) for Frequency...

Ericsson said the downlink peak rate of nearly 4.4 Gbps was reached by combining 20 megahertz of AWS, 80 megahertz of CBRS and 200 megahertz of C-band Ericsson and MediaTek said they have successfully merged four channels – one FDD and three TDD – to...

The carrier aggregation trial was supported by Nokia and MediaTek At O2 Telefónica's Innovation Cluster near Berlin, the carrier has successfully aggregated sub-6 GHz spectrum frequencies in a two-component carrier uplink Carrier Aggregation (CA) trial on 5G Standalone. The trial, which was supported by Nokia and MediaTek,...

Huawei said that a total of 230 carriers around the world have already launched commercial 5G services BANGKOK, THAILAND- Huawei rotating chairman Ken Hu called for a cross-industry effort with the aim of pushing so-called "5.5G" technology, which will enable advanced services and applications for...

The 4CC data trial combined Optus’ low-band spectrum and 2,100MHz FDD bands with 2,300MHz and 3,500MHz TDD bands Australian operator Optus has completed what it claims to be the first four component carrier aggregation 5G standalone data call in the country. To achieve this milestone, Optus...

Zain Bahrain exec: 'Carrier Aggregation is the foundation for deploying high-performing 4G and 5G networks' As part of its ongoing 4G/5G partnership with Ericsson, Zain Bahrain has implemented the vendor’s 5G Time Division Duplex (TDD/TDD) Carrier Aggregation (CA) on a commercial device to use on...

The trial combined three component carriers across 5G FDD spectrum (30MHz of 700MHz/n28) and 5G TDD spectrum (100+60MHz of 2.6GHz/n41) China Mobile, with partners Nokia and MediaTek, has claimed verification of the world's first 3 Components (3CC) Carrier Aggregation (CA) technology in a test...

LOS ANGELES – This week, at Mobile World Congress Los Angeles (MWC LA), Samsung Electronics unveiled two new Massive MIMO radios, both of which are dual-band. The first is the C-Band/CBRS Dual-band 16T16R Massive MIMO Radio that integrates with the company’s virtualized Radio Access...

China Unicom first tested Huawei's 5G Super Uplink on its commercial networks in 2020 China Unicom and Huawei announced last week that they have deployed Huawei's 5G Super Uplink at more than 1,000 5G commercial sites in Beijing. The deployment, which was carried out over...

Ericsson said it is launching a three-sector dual-band radio to help communications service providers (CSPs) increase their Frequency Division Duplex (FDD) 5G frequency capacity. In a release, the Swedish vendor said that the launch of Radio 6626 will benefit carriers even as their site towers...

In general, FDD is considered better for coverage and TDD better for capacity Mobile operators are looking to carrier aggregation (CA), which allows them to use multiple sub-6 GHz spectrum channels simultaneously, as a method of increasing the bandwidth and speeds of their 5G networks....

The physics of time-division duplexing in radio communications means 5G could, in certain frequency bands, struggle to achieve the ultra low latencies it promises. Worse, in some markets, regulatory forces have compounded the challenge with backwards rules about 5G radio operations. As a consequence, radio...

  Sunwave CrossFire Digital DAS Platform Takes on the Challenging Malaysian Deployment Transit infrastructure, particularly rail systems, are notoriously difficult to connect to cellular networks given the varying mobility conditions, need for underground penetration, as well as the fluctuating capacity demands of both the transport authority...

  Although much of the dialogue on 5G spectrum in the US has focused on millimeter (mmWave) spectrum, it is not clear whether the mmWave spectrum is suitable for mobile network deployment in the near to mid-term future. This is exactly why Verizon is concentrating on...

T-Mobile US will test FDD with Ericsson 5G equipment The network infrastructure community remains laser-focused on facilitating the customer transition from LTE to 5G with pre-standard equipment that can be upgraded to the next-generation standards once it's agreed to by 3GPP. Ahead of Mobile World...

EJL Wireless Research estimates that macrocell digital baseband unit (BBU) shipments increased by 13% in 2016 as compared with shipment levels in 2015. While Huawei Technologies maintained its market leadership position in 2016, we note that Nokia outperformed the overall market and increased market...
