How Metaverse Drives Data Center, Connectivity Investments

As video content distribution has shaped global demand for inter-continental data transport and high-speed connections between major data centers, the metaverse will shape data center and connectivity network requirements. And the key words are “more” and “less.”


“Making the metaverse a reality will require significant advancements in network latency, symmetrical bandwidth and overall speed of networks,” says Dan Rabinovitsj, Meta VP for connectivity. 


The metaverse “will require innovations in fields like hybrid local and remote real-time rendering, video compression, edge computing, and cross-layer visibility, as well as spectrum advocacy, work on metaverse readiness of future connectivity and cellular standards, network optimizations, improved latency between devices and within radio access networks (RANs), and more,” he says. 


Already, experts predict Metaverse environments will require more data centers, more edge computing, more distributed computing, more collocation, more content distribution mechanisms, will require more power consumption and more cooling.


Eventually, fully-developed metaverses will require advances in chip technology as well. Beyond all that, blockchain will probably be necessary to support highly-decentralized value exchanges. And it is impossible to separate metaverse platforms and experiences from use of artificial intelligence, for business or consumer uses.

If metaverses are built on persistent and immersive computing and tightly-integrated software stacks, platforms will be necessary. New developments in chip manufacturing also will be needed. 


For connectivity providers--especially internet service providers--far lower latency will be key. Today’s latency-sensitive applications such as video calling and cloud-based games have to meet a round-trip time latency of 75 milliseconds to 150 ms. Multi-player, complex games might require 30 ms latency. 


“A head-mounted mixed reality display, where graphics will have to be rendered on screen in response to where someone is focusing their eyes, things will need to move an order of magnitude faster: from single to low double digit ms,” says Rabinovitsj. 


Image rendering will require edge computing. “We envision a future where remote rendering over edge cloud, or some form of hybrid between local and remote rendering, plays a greater role,” he adds. “Enabling remote rendering will require both fixed and mobile networks to be rearchitected to create compute resources at a continuum of distances to end users.”


Bandwidth could increase by orders of magnitude over what is required to view 720p video on a standard smartphone screen. That might work with just 1.3 Mbps to 1.6 Mbps of downlink throughput. 


But a head-mounted display sitting just centimeters from the eyes required to display images at retina grade resolution will need to be many orders of magnitude larger, he notes. 


To be sure, most of what happens that is part of metaverse experiences rests on things that happen up the stack from computing and communications.

But we already can see how metaverse support will require changes in computing architecture and network capabilities.

FTTH Network Element Deveolopments Change Cost, Architecture Possibilities

For a variety of reasons--higher government subsidies; higher consumer demand; higher interest by institutional investors in digital infrastructure assets; evolution of the network elements and a change in financial return assumptions--fiber to the home has an investment profile that is higher than it used to be. 


On the network cost front, some sort of subtle changes in network element features also play a role. 


Telco outside plant architectures were strict “star” designs in the copper era. Though network designed used multiplexing as much as possible, the basic design was a star.

But there are some changes that can affect fiber to home construction cost. Corning, for example, touts the use of its connectors that do not require splicing. Since labor--not materials--represent the biggest portion of FTTH network construction, total costs should be lower when less labor is required. 


Still, materials costs are different when an architecture that is more like a “bus” or “tree” and less like a “star” is possible. For terrestrial networks using cables, the advantage of the bus is less cabling bulk. 


Telco FTTH networks can use architectures that are partly bus and partly star. The advantage includes some savings on cable, as is true for bus designs.

In Corning’s case, connectors that eliminate splicing are not just a way to speed construction, they also allow more hybrid architectures that are more like buses in the trunking part of the network (which allows more sharing and multiplexing) while retaining the star for distribution to end points. .

The practical implications for FTTH network construction is that costs should be lower than they have been in the past. That, plus changes in consumer demand (higher) and government subsidies (also higher) plus higher demand on the part of institutional investors for digital infrastructure assets as a form of real estate, are propelling faster investment in FTTH in the U.S. market.

Cox Boosts Speed on its "Most Purchased" Tier to 250 Mbps

With attention on U.S. headline home broadband speeds of 2 Gbps to 5 Gbps, it is easy to overlook the fact that most consumers do not buy services operating at the headline speeds. 


In fact, at Cox Communications, a cable company with customers concentrated in metro areas, the most-popular service tier  had offered speeds up to 150 Mbps. But Cox now has boosted speeds on that tier by 67 percent to 250 Mbps at no extra charge.


That is part of the typical pattern, where speeds for the most-purchased tiers increase, while prices generally remain the same, with inflation increases being the main changes in posted retail prices. 


Cox has committed to boosting its top tier service to 10 Gbps over the next few years. As speeds at the top grow, so will speeds on the other tiers below. 


In the fourth quarter of 2021, for example, roughly 70 percent of U.S. home broadband customers purchased services operating between 100 Mbps and 400 Mbps, generally measured using Wi-Fi-connected devices. 


That of course means the internet service provider connection delivered to the home ran faster than those measured speeds. 


source: Openvault 


Those sorts of tests also are important because end user experience is dictated as much by in-home Wi-Fi performance as it is by what the ISP is actually delivering to the home. User experience also is shaped by the purchasing decisions consumers make.


It is one thing to describe the speeds consumers choose to purchase; it is another thing to describe what speeds they are able to get. The former is consumer behavior; the latter is network performance.

Hybrid Work Might be a Necessary Enteprrise Compromise

A study conducted by Incisiv for AT&T suggests permanent changes in work venues, though fully-remote work might be less common than many project, as work moves “back into the office” by 2024. 


Such changes matter for all larger enterprises, but also will affect internet access provider, mobility and fixed network capital investment and other priorities. If there are fewer workers at large company sites, on average, demand for bandwidth and other connectivity support will diminish, from expected prior levels. 


Conversely, network support in suburban areas during daytime hours should remain higher than originally foreseen. Growth in demand for mobile internet access also could be affected, if fewer workers, on average, are traveling back and forth from office sites and out and about less often. 


source: AT&T 


Much will depend on whether employees or employers get their way, as there is a huge difference of opinion about the desirability of in-office work. 


Employees prefer remote work over office work, while employers prefer in-office modes.About 86 percent of employees want a distributed model while 64 percent of employers do not want a distributed model. 


source: AT&T 


So much hinges on which view prevails. In fact, it might be fair to note that executives hold inherently contradictory views about the future of remote work. On one hand, 91 percent believe remote work will decrease by 2024. That makes sense if even some workers return to the office, in hybrid deployments. 


And while 70 percent of executives believe hybrid will be the default, 58 percent also believe employees “have not been innovative” in distributed work modes. Also, about 40 percent of executives say their ability to maintain company culture, using distributed basing, has been diminished.


More than half of non-executive workers believe company culture has been negatively affected by enforced remote work. 


source: AT&T 


Of non-executive personnel, about 42 percent say maintaining company culture will be harder in a hybrid environment. 


Given the conflicting views, it might be safe to say that we presently have imperfect knowledge of how work venues might change in coming years. If enforced remote work is no longer necessary, there should be some movement back to office basing, at least part of the time. 


But employees will resist. And CxOs are likely to continue insisting they lack oversight of employee performance when workers are remote. “Hybrid increasingly will be the compromise.

Do Office Vacancies Suggest Dispersed Work is Here to Stay?

With the caveat that the situation could change, office vacancies in major U.S. cities appear to be rising. Should that pattern continue, it would tend to confirm the notion that permanent work from home and hybrid work modes could become a permanent reality.

That, in turn, could mean fewer workers in the office at any given time; fewer workers eating in local restaurants or taking public transportation; shopping downtown or parking. 


Lower office utilization also implies fewer people using communications and gear at the office; less use of mobile communications downtown and more distributed usage of internet access and applications across metro areas. 


Aside from financial pressure on owners of office real estate; restaurant and retail shop owners; transit systems and parking lots, suppliers of business software and connectivity services will see changes. 


If network usage flattens in urban cores and increases in suburban areas, capital investment requirements could shift as well. There could well be less urgency for upgrades of downtown cell sites and more diffuse demand for upgrades across broader suburban areas, with fixed network broadband becoming an even more important mobile capacity offloading platform. 


Both mobile and fixed network demand peaks for “work” reasons could flatten a bit. App security will be a bigger issue as more workers work remotely, routinely. People might move away from urban cores to outlying areas, again changing the geographies where additional capacity has to be added.  


BT Pauses Digital Voice Changeover: Customers Were Confused, Disappointed

BT says it botched the transition of voice services on its fixed network from analog to voice over IP, and is “pausing all further Digital Voice switch-overs for customers who don’t want to move to the new technology straight away,” says Marc Allera, BT CEO, consumer division.


As it happened, BT underestimated both the customer confusion and the disruption power outages would cause for a service that formerly was network powered and often required new equipment to support broadband connections for those who did not have such service. 


The pause will allow BT time to create resiliency solutions including hybrid phones that switch to mobile in case of local power outages; battery backup units; mobile-only replacements for landline service and better mobile service to support those alternatives. 


“We underestimated the disruptive impact this upgrade would have on some of our customers,” says Allera. “With hindsight we went too early, before many customers, particularly those who rely more heavily on landlines, understood why this change was necessary and what they needed to do.”


SOURCE: itu 


The customer expectations issues are likely enhanced by the huge switch in use of voice services. Use of fixed network voice peaked globally about 2004. Since then, people have increasingly preferred mobile as the device and network for voice calls. In the United Kingdom, mobile voice usage has displaced fixed network voice, for example. Mobile call volume is an order of magnitude higher than fixed network voice volume. 


Twenty years ago, as service providers began the transition to IP voice, great concern was expressed about the end of network power, as the vaunted “five nines” (availability at 99.999 percent of the time) levels of service would be ended. 


Executives in most cases seemed not to factor in the abandonment of fixed network voice services and the replacement by mobility services. Customers quickly understood that mobile phones do not work if battery power is exhausted. 


That was never the case for fixed-line services, where customers expected their phones would continue to work in cases where local power was lost. 


In truth, powering issues had effectively grown for decades, even before the replacement of analog voice with VoIP. As consumers switched from corded phones to cordless, they already had begun to experience “loss of dial tone” whenever local power was lost. 


The issue BT might have faced was that most younger consumers had moved off the landline voice network or never had such service. 


That means a growing percentage of landline voice users are older and presumably less used to new technology, which exacerbates the technology transition. BT in this case appears not to have thought through the cultural issues it would face.
