AT&T has provided an update of its live 5G trials, with the carrier saying it is planning to offer 5G devices to its customers by the end of 2018. According to a blog post by president of Technology and Operations Melissa Arnoldi, AT&T is using its current 5G trials to gather "mountains of data and insights" on what is working, what needs to be changed, why certain results are occurring, whether millimetre-wave (mmWave) spectrum is working for 5G, and how it can hit high speeds. "We had a lot of questions when we started, and we're confident we have all the answers we need to deploy a mobile 5G network that works for people all over the country," Arnoldi wrote. Through the trial in Waco, Texas, Arnoldi said AT&T was able to attain 1.2Gbps speeds over an mmWave 5G service to locations more than 150 metres away from the cell site, with latency of between 9 and 12 milliseconds. Small and medium-sized businesses participated in the Waco trial, with AT&T saying it was … [Read more...] about AT&T clocks gigabit 5G connections in first three cities
5g network architecture
January 29, 2018 - Written By Dominik Bosnjak Nokia on Monday detailed its 5G architecture called Future X and explained the scope of the solution that’s meant to serve as the foundation for its reference silicon design, as well as the key to enabling its upcoming products and services relying on the next generation of mobile networks. Besides massive performance increases that are promised across all relevant metrics, the Finnish telecom giant claims its solution is perfectly scalable, being able to support any kind of deployment scenarios. Most industry watchers agree that scalability will be an important factor in the 5G revolution, with the networks themselves being expected to allow for entirely new technologies that are likely to lead to constantly growing infrastructural requirements. Nokia is planning to cater to such frequently shifting needs by relying on network slicing, i.e. virtualizing its network architecture so as to dedicate specific portions of it to … [Read more...] about Nokia Details Its 5G Network Architecture ‘Future X’
Network slicing is a specific form of virtualization that allows multiple logical networks to run on top of a shared physical network infrastructure. The key benefit of the network slicing concept is that it provides an end-to-end virtual network encompassing not just networking but compute and storage functions too. The objective is to allow a physical mobile network operator to partition its network resources to allow for very different users, so-called tenants, to multiplex over a single physical infrastructure. The most commonly cited example in 5G discussions is sharing of a given physical network to simultaneously run Internet of Things (IoT), Mobile Broadband (MBB), and very low-latency (e.g. vehicular communications) applications. These applications obviously have very different transmission characteristics. For example, IoT will typically have a very large number of devices, but each device may have very low throughput. MBB has nearly the opposite properties since it will have … [Read more...] about What is the difference between network slicing and Quality of Service?
By AppleInsider Staff Tuesday, February 20, 2018, 09:31 pm PT (12:31 am ET) After teasing an initial rollout phase for its next-generation 5G network in January, AT&T on Wednesday got a little more specific by naming the first three cities that will gain access to the speedy mobile technology by the end of 2018. In a press release posted to its official website, AT&T said Atlanta, Dallas and Waco will be among a batch of 12 U.S. cities to benefit from standards-based mobile 5G later this year. The carrier will announce the remaining 9 cities in the coming months. "After significantly contributing to the first phase of 5G standards, conducting multi-city trials, and literally transforming our network for the future, we're planning to be the first carrier to deliver standards-based mobile 5G - and do it much sooner than most people thought possible," said Igal Elbaz, SVP of Wireless Network Architecture and Design at AT&T. AT&T initially announced plans to launch 5G … [Read more...] about AT&T to launch mobile 5G in Atlanta, Dallas and Waco in 2018
In early January, AT&T announced plans for launching a legit 5G network in twelve different markets by the end of 2018. The carrier remained tight-lipped at the time about which markets would be graced with this early access, but now we have the names of three of those twelve. According to a post on AT&T's newsroom, "parts of" Dallas, Atlanta, and Waco, Texas will be among the first cities to be serviced with true 5G speeds. Other supported cities will be announced over the next few months, and following these early tests, AT&T will expand its lineup of 5G-capable smartphones in 2019. Commenting on this announcement, AT&T's Senior Vice President of Wireless Network Architecture and Design, Igal Elbaz, said: After significantly contributing to the first phase of 5G standards, conducting multi-city trials, and literally transforming our network for the future, we're planning to be the first carrier to deliver standards-based mobile 5G – and do it much sooner … [Read more...] about These are three of the cities where AT&T’s 5G network will launch in 2018
