Ericsson CTO Erik Ekudden’s view on a new backhaul option in 5G

Today millimeter wave (mmWave) spectrum is valued mainly because it can be used to achieve high speeds and capacities when combined with spectrum assets below 6GHz. But it can provide other benefits as well. For example, mmWave spectrum makes it possible to use a promising new wireless backhaul solution for 5G New Radio – integrated access and backhaul (IAB) – to densify networks with multi-band radio sites at street level.

The latest Ericsson Technology Review article explains the IAB concept at a high level, presenting its architecture and key characteristics, as well as examining its advantages and disadvantages compared with other backhaul technologies. It concludes with a presentation of the promising results of several simulations that tested IAB as a backhaul option for street sites in both urban and suburban areas.

Integrated access and backhaul – a new type of wireless backhaul in 5G

June 23, 2020

Integrated access and backhaul (IAB) is an advanced concept in 5G that shows significant promise in addressing the challenge of wireless backhaul of street sites. IAB has several advantages compared with other backhaul technologies, and if used properly, it could become an essential backhaul solution for 5G New Radio (NR) networks, especially in high bands (mmWave) where wide spectrum is available. Simulations at Ericsson show that IAB is an attractive complement to fiber, with the ability to provide backhaul for street sites in urban and suburban areas.

Critical IoT connectivity: Ideal for time-critical communications

June 2, 2020

Critical IoT connectivity is ideal for a wide range of Internet of Things use cases across most industry verticals. Mobile network operators (MNOs) are uniquely positioned to address time-critical use cases by leveraging their existing assets and new technologies in a systematic fashion. Critical IoT addresses the time-critical communication needs of individual users, enterprises and public institutions. It is intended for time-critical applications that demand data delivery within a specified time duration with required guarantee (reliability) levels, such as data delivery within 50ms with 99.9 percent likelihood (reliability).

The future of cloud computing: Highly distributed with heterogeneous hardware

May 12, 2020

The future of cloud computing is being shaped by the combination of the growing popularity of distributed solutions and increased reliance on heterogeneous hardware capabilities. As the role of distributed compute and storage capabilities in cloud computing continues to expand, network operators, who have large, distributed systems already in place, have a golden opportunity to become major cloud players. However, operators must overcome a few technical challenges – most notably in relation to heterogeneous compute and storage capabilities – to deliver best-in-class application performance.

Optimizing UICC modules for IoT applications

April 14, 2020

The ability to deliver low-cost Internet of Things (IoT) devices on a mass scale is at risk of being hampered by the high cost of the universal integrated circuit cards (UICC) currently required to provide connectivity. The work to develop a less sophisticated – and therefore less costly – alternative is underway, but in the meantime, the IoT requires workarounds that either lower device cost or justify the price of UICCs by leveraging more of their capabilities. Ericsson proposes a number of options that either reduce the complexity of using UICCs or leverage them to provide additional value.
