A Service-Based Architecture for enabling UAV enhanced Network Services

A recent paper, accepted in IEEE Network Magazine, explores the role of UAVs in facilitating core NFs with radio and backhaul capabilities. It analyses the required advancements in SBA, considering air traffic management, weather conditions and network connectivity and introduces new resource control and management functions to efficiently deal with topology and service assurance.
The use of UAVs for enhancing 5G network services is then evaluated and shown to be useful considering a range of V2X applications. The first part analyses the use of UAVs to enable network services across the RAN, core network and backhaul for supporting various vehicular-to-everything (V2X) applications considering a high mobility environment that brings challenges in service continuity, latency and reliability. Meanwhile, the experimentation analysis, presented in the second part, provides insightful results related to the use of UAVs as edge cloud, evaluating the potential of hosting an ACS function or any other core NF.

The paper is available here.

We have made introductory tutorials on V2X and NTN (see related posts at bottom), in addition to various blog posts on the this topic. 5G lays foundation to these kinds of solutions becoming a reality. With unlicensed and lightly licensed spectrum being available in many different parts of the world, we will soon be seeing these kinds of networks in operation.

IEEE 802.11bn Ultra High Reliability (UHR), a.k.a. Wi-Fi 8

Back in 2020 we looked at the introductory post of Wi-Fi 7 which was followed up by a more detailed post in Feb 2022. We are now following on with an introductory post on the next generation Wi-Fi.  A new paper on arXiv explores the journey towards IEEE 802.11bn Ultra High Reliability (UHR), the amendment that will form the basis of Wi-Fi 8. Quoting selected items from the paper  below: After providing an overview of the nearly completed Wi-Fi 7 standard, we present new use cases calling for further Wi-Fi evolution. We also outline current standardization, certification, and spectrum allocation activities, sharing updates from the newly formed UHR Study Group. We then introduce the disruptive new features envisioned for Wi-Fi 8 and discuss the associated research challenges. Among those, we focus on access point coordination and demonstrate that it could build upon 802.11be multi-link operation to make Ultra High Reliability a reality in Wi-Fi 8. The IEEE 802.11bn UHR: Whose ...

Laser Inter-Satellite Links (LISLs) in a Starlink Constellation

When we first talked about Starlink back in 2019 , we saw in the video that the concept involved laser communication to communicate between the satellites. While the initially launched satellites did not have the laser communication mechanism built in, it looks like they are being added to the newer ones.  A report from Fast Company in late 2021 said: One of the next big upgrades in telecom will involve satellites firing lasers at each other—to beam data, not blow stuff up. The upside of replacing traditional radio-frequency communication with lasers, that encode data as pulses of light, can be much like that of deploying fiber-optic cable for terrestrial broadband: much faster speeds and much lower latency. “Laser links in orbit can reduce long-distance latency by as much as 50%, due to higher speed of light in vacuum & shorter path than undersea fiber,” SpaceX founder Elon Musk tweeted in July about the upgrade now beginning for that firm’s Starlink satellite constellation. ...

NTT Docomo's Disaster Countermeasures to Keep People Connected

Recently I blogged about Disaster Roaming in 3GPP Release-17. While this will take time to be implemented worldwide, it is already available in Japan, maybe not in the 3GPP standardised way. Similarly, back in 2011, I blogged about Earthquake and Tsunami Warning service (ETWS) from NTT Docomo's Journal, it was two days before the  2011 Tōhoku earthquake and tsunami hit. Japan is no stranger to earthquakes, typhoons, and other natural disasters, which can have a devastating effect on infrastructure. To ensure that the mobile networks keep functioning, operators work extremely hard to ensure people remain connected one way or another. NTT Docomo has released a video detailing the countermeasures to keep everyone connected in case of emergencies. The following detail is provided with the video: DOCOMO's network is no exception, and our services could get cut off by a base station power outage, disconnected fiber-optic cable, or other malfunctions. DOCOMO established the three p...
