Story “5G will be a major component of the ‘bandwidth mix’ of the future.” – Juliet Walker, Globecast on average, we will see more UHD content and the HD content will be streamed even at large scale like in stadiums.” “Building up 5G will help the networks to cope,” says Omdia’s Wallis-Jones, who suggests that the benefits offered by millimetre wave spectrum are “immense” with further spectrum auctions set to further help. “Access networks will be massively strengthened.” With an eye on the current Covid-19-enforced lockdowns, PP Foresight’s Pescatore says that networks are coping well today given the increasing demands of working at home, educating kids and entertaining the entire household. “The move to a more software- driven architecture underpinned by AI, cloud with more services served from the edge, makes attacks more likely. Security and privacy represent key requisites to support the rollout of next generation networks.” EFFICIENCY. “With 5G we will for sure see better spectrum efficiency in terms of bits/ Hz when higher bandwidth will be considered which would necessarily mean higher data rates,” says Rohde & Schwartz’s Aziz Taga. “Nevertheless, 5G in unicast mode would not necessarily mean better QoS and higher user experience. Why? Because this has been already promised by 3G, HSPA, LTE and 4G but the problem is still the same: limited resources. Although there will be more potential spectrum resources, we need also to consider that the number of connected devices is expected to be much higher than the case in 4G. Therefore, the consideration of Broadcast and Multicast is a must. 5G multicast creates opportunities for broadcast network operators to make their infrastructure more dynamic and allow them to discover new distribution features. Also, this technology helps mobile network operators to offload their heavy streaming and data loads so that they avoid infrastructure over-provisioning and therefore serve their consumers with higher Quality of Service while reducing Capex and Opex.” “The growth in 5G mobile video viewing is expected to place unprecedented scaling 10 EUROMEDIA demands on wireless network operators,” and what will drive such take up, Everson warns Velocix’s Brickmeier. “To avoid network reports that South Korea, the US, China and congestion impacting the video quality Japan are leading the way in 5G consumer experienced by consumers, operators need adoption as they are online now. “Enterprise to scale-out their content delivery systems, implementation will begin primarily with using technology that more efficiently routes proof-of-concepts in late 2020 and increase and delivers video traffic over IP and wireless in 2021 with live deployments. In addition to networks. For instance, by using mobile- the countries mentioned, we also see some optimised CDN technology with multi-tier western European countries rapidly preparing delivery and inter-cache communications, for this – especially Germany.” demands over mobile backhaul networks “As of January 2020, commercial 5G can be reduced by as much as 30 per cent. networks have been deployed in 378 cities Another key development is multi-access edge across 34 countries,” notes Forrest. “EMEA computing (MEC), which allows elastically leads the way, counting 168 cities with scalable caches to be deployed closer to commercial 5G services, while Asia follows consumers at the periphery of 5G radio with 156 cities, and the Americas with 54 access networks. Used together, these newer cities. But, of course, all are considered as technologies can provide a reliable and cost- fledgling networks, available in select parts effective alternative to expensive backhaul of cities, as operators secure more mobile network upgrades.” spectrum and begin to extend their coverage “It’s the famous Jevons paradox,” observes and capacity.” V-Nova’s Meardi. “The efficiency with which According to Forrest, there have been a resource is used tends to increase (rather differing strategies for 5G deployment across than decrease) the rate of consumption of that countries. “For example, whilst mobile resource. 5G should certainly enable greater operators in the USA are battling it out to mobile video consumption of all media types, improve coverage and gain subscribers, but demand is likely to continue rocketing to initially using the promise of high bandwidth quickly occupy the additional over mmWave spectrum, bandwidth that becomes in South Korea all three available, especially with major operators instead the ‘new normal’ of digital collaborated to build the collaboration.
