Today, we are discussing 5G deployment, particularly in developed countries. Can anyone tell me how high the 5G penetration rate is in some of these nations?
I think it can exceed 50% in certain areas, especially urban places.
Exactly! In fact, as of the mid-2020s, several regions in developed countries have surpassed this benchmark. One of the key drivers for this success is the strong economic incentive. Can anyone elaborate on what that means?
It means that mobile operators expect to make a lot of money from 5G because consumers want faster speeds and new applications.
Right, the potential for revenue is substantial due to demand for services like cloud gaming. This is summarized as the 'ECONOMICS' driver: Economic growth, Community demand, Existing infrastructure, Needs of consumers, Ownership of spectrum, Market competition, Government support, and Availability of devices! Letβs remember this acronym when talking about drivers.
What about the success stories? I heard South Korea is quite advanced with 5G.
Yes, great point! South Korea leads with swift deployment and a tech-savvy population. China also shows immense scale in 5G deployment due to significant infrastructure investments.
What about the U.S.?
The U.S. uses a mix of low, mid, and high-frequency bands, rapidly expanding coverage through competitive strategies. Remember, competition drives faster rollouts! To sum it up, developed nations leverage economic drivers for success in the deployment of 5G.

Now let's shift our focus to low-to-middle-income countries. What challenges do you think they face in deploying 5G?
I believe financing is a big issue, especially with high capital expenditures.
Correct. Deploying 5G networks requires substantial investments, and in LMICs, financing these can be extremely tough due to existing debts. Can anyone explain why affordability of spectrum is another barrier?
If spectrum auction prices are very high, it eats into the money that could be spent on building the infrastructure.
Absolutely, and lower average revenue per user (ARPU) compounds the situation because many people can't afford these services. This cycle makes investment risky. How does existing infrastructure impact deployment?
Without a dense fiber optic backhaul, operators can't support the traffic needs of 5G effectively.
Exactly! Many LMICs have limited infrastructure, which can hinder deployment. Letβs summarize that there are economic considerations and infrastructure gaps that dramatically affect 5G implementation in LMICs.
Bridging the Digital Divide

Finally, letβs discuss bridging the digital divide. Why is this significant when it comes to deploying 5G?
Since many people in LMICs still lack basic internet connectivity, efforts should first focus on 3G/4G before moving to 5G.
Exactly! Many LMICs prioritize basic connectivity, which makes sense when resources are limited. Can anyone think of a potential benefits to expanding broadband access?
If we boost basic connectivity, it would prepare populations for more advanced services in the future, like 5G.
Well said! Bridging this divide is key to ensure that when 5G networks are rolled out, they can serve a large number of users effectively. To conclude, itβs vital that we recognize the need for infrastructure investments alongside technological advances.

Deploying 5G, especially SA 5G, is inherently capital-intensive, requiring investments in new radio equipment (gNodeBs), upgrading or deploying dense fiber backhaul, and building out a new 5G Core Network (5GC). For operators in LMICs, financing such massive investments can be extremely difficult given existing debt burdens or limited access to capital.
Detailed Explanation
Deploying 5G technology involves significant costs known as capital expenditure (CapEx). This includes spending on new radio equipment, network upgrades, and the fiber backhaul necessary for 5G to function effectively. Many operators in low-to-middle-income countries (LMICs) struggle to afford these investments due to existing debt and limited financial resources. Therefore, the financial aspect poses a serious challenge when trying to implement 5G networks in these regions.
Examples & Analogies
Think of building a new restaurant. The owner needs to invest money into kitchen equipment, decor, and staff before opening. If they don't have the funds upfront, it becomes difficult to get started. Similarly, telecommunications operators need substantial investments to set up new 5G networks, and if they lack funds, they can't proceed.
Affordability of Spectrum

Spectrum licenses often represent a significant portion of 5G deployment costs. High spectrum auction prices can strain operator finances and divert funds that could otherwise be used for infrastructure rollout.
Detailed Explanation
When telecommunication companies want to operate a 5G network, they need 'spectrum licenses,' which give them the right to use specific frequency bands. The cost of obtaining these licenses is often high, and winning them at auction can consume substantial resources. If companies spend too much on spectrum, they may not have enough money left to build the necessary infrastructure to support their new service, leading to deployment delays or limitations.
Examples & Analogies
Imagine planning a big concert. You need a venue and artists, but before that, you have to pay for the rights to use the space. If you spend all your money on securing the venue, you might not have enough left to hire performers, which would leave your concert incomplete. Similarly, operators must balance spending on spectrum licenses with building the infrastructure.
Low Average Revenue Per User (ARPU)
Unlock Audio Book

Users in LMICs generally have lower disposable incomes, leading to lower ARPU for mobile services. This makes it harder for operators to justify and recoup the substantial 5G investments through traditional consumer services.
Detailed Explanation
Average Revenue Per User (ARPU) is a crucial metric for telecom operators, especially when evaluating their service offerings. In LMICs, consumers tend to have lower incomes, which means they spend less on mobile services. Consequently, telecommunication companies may find it challenging to generate enough revenue to justify their large investments in 5G. This situation complicates financial planning because they need to ensure that their new services can be profitable over time.
Examples & Analogies
Consider a coffee shop selling high-end espresso. If most customers can only afford instant coffee, the cafΓ© will struggle to make a profit from its premium offerings. Similarly, telecom companies might find their expensive 5G services unnecessary for consumers in LMICs due to the lower ARPU, making it hard to recover their investments.
Device Affordability

The cost of 5G-enabled smartphones and other user devices can be prohibitively high for a large segment of the population, hindering adoption even where 5G networks exist.
Detailed Explanation
For individuals to access 5G services, they need devices such as smartphones that are capable of using this technology. However, the price of 5G-compatible devices can be high, which may prevent many potential users, particularly in less affluent regions, from adopting 5G. Even if 5G networks are available in their area, the lack of affordable devices can significantly slow down the growth of 5G adoption.
Examples & Analogies
Think about how some people may want to attend a concert but cannot afford a ticket. Even if the concert is happening nearby and they can hear the music, they can't enjoy the experience fully. In the same way, users cannot take advantage of 5G networks if they donβt have affordable, compatible devices.
Limited Viable Use Cases (Initial Stages)

While 5G promises transformative industrial applications, the immediate demand for such advanced services might not be as mature in LMICs as in developed economies. The primary need often remains basic mobile broadband or enhancing 4G coverage.
Detailed Explanation
5G technology introduces many advanced applications that can revolutionize industries. However, in many LMICs, the demand for these sophisticated services may not yet exist. Instead, people's immediate need often revolves around basic mobile connectivity or improving existing 4G networks. This disparity indicates that operators might struggle to find business cases to justify their 5G investments optimally.
Examples & Analogies
It's similar to introducing an expensive espresso machine to a cafΓ© where most customers only drink instant coffee. Without a customer base demanding high-end coffee experiences, the investment will not see returns. By the same token, in LMICs, the immediate focus is often on securing basic services rather than advanced applications made possible by 5G.
Lack of Dense Fiber Backhaul

A critical challenge. Many LMICs lack the extensive fiber optic infrastructure required to support the massive data volumes and low-latency demands of 5G base stations. Deploying new fiber is costly, time-consuming, and faces significant right-of-way issues.
Detailed Explanation
Fiber backhaul refers to the optical fiber connections that transmit data to and from 5G base stations. Unfortunately, in many LMICs, this fiber infrastructure is either underdeveloped or nonexistent. Without it, the demands of 5G, which requires rapid and large data transfers with minimal delays, cannot be met. Establishing new fiber systems poses both high costs and logistical challenges, such as gaining permission to lay cables on public or private land.
Examples & Analogies
Imagine trying to build a highway in an area where no roads exist. It would be costly and complicated due to land permissions, construction tasks, and materials needed. Similarly, building the necessary optical fiber backhaul infrastructure for 5G in LMICs faces similar challenges, slowing down deployment.
Insufficient Cell Site Density
Unlock Audio Book

5G, particularly when utilizing higher frequency bands (mid-band and mmWave), requires a denser network of base stations compared to 4G for equivalent coverage. Many LMICs still have sparse 4G networks, meaning operators would need to build significantly more new sites, which is expensive and complex.
Detailed Explanation
5G technology operates more effectively with a higher density of base stations, especially when using certain frequency bands that do not travel far or penetrate obstacles well. Compared to 4G, this means telecom operators need to build a lot more cell sites to achieve similar coverage. In many LMICs, the existing 4G infrastructure is already sparse, meaning creating an adequate 5G network will involve substantial investments, which can be a significant barrier to deployment.
Examples & Analogies
Consider trying to organize a large event in a big field but using only a few small tents for shelter. If there are not enough tents, many people will be left out in the elements. Just like that, without enough 5G cell sites, the technology's benefits wonβt reach many users in LMICs, posing challenges for operators.
Unreliable Power Supply

Many rural and even some urban areas in LMICs suffer from unreliable electricity grids. 5G equipment, especially with Massive MIMO, can be more power-intensive, exacerbating challenges related to backup power and operational costs.
Detailed Explanation
5G technology, especially advancements like Massive MIMO, is often power-hungry. In many LMICs, local electricity supply may be inconsistent or even lacking, which can put strain on the operation and reliability of 5G networks. This power unreliability can lead to increased operational costs for telecommunications operators as they may need to invest in backup solutions, making deployment even more expensive.
Examples & Analogies
Think about how a restaurant needs stable power to keep cooking. If the power goes out frequently, the food might spoil, and customers get frustrated. Similarly, if 5G towers can't rely on stable electricity, they risk malfunctioning or being temporary, frustrating users and hurting profits.
Logistical Challenges

Remote or geographically challenging terrains, combined with less developed transportation networks, can make equipment transport, installation, and ongoing maintenance extremely difficult and expensive.
Detailed Explanation
In LMICs, there are often challenges related to geography, such as mountains, rivers, or densely populated urban areas, which complicate the transportation of equipment needed for 5G networks. Furthermore, if the existing transportation infrastructure (like roads and railways) is underdeveloped, it makes the whole process of installing and maintaining equipment more complex and costly for operators.
Examples & Analogies
Itβs like trying to deliver supplies to an island with no proper docks. Even if you have the supplies, getting them to the island is a major logistical challenge if the transport options are limited. Similarly, without effective routes and systems, supporting 5G infrastructure becomes a daunting task in LMICs.
Regulatory and Permitting Hurdles
Unlock Audio Book

Bureaucratic processes, inconsistent regulatory frameworks, and lengthy permitting approvals for new cell sites can significantly delay and increase the cost of network deployment.
Detailed Explanation
Telecommunications operators must navigate complex regulatory processes to establish new 5G networks, including obtaining permits to place new cell sites. These bureaucratic hurdles can vary widely by region and can be time-consuming and costly, which can lead to increased deployment costs and delays. Inconsistent rules can make it difficult for operators to plan their investments efficiently.
Examples & Analogies
Think about trying to get a building permit to construct a new school. If the process is long, confusing, and changes often, you could spend months waiting before you can even start building. In similar fashion, the time it takes to receive regulatory approvals delays 5G network rollout.
Digital Divide and Basic Connectivity Focus
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
In many LMICs, the priority remains expanding basic 3G/4G coverage and connectivity to underserved populations, rather than immediately jumping to 5G. Investing in universal basic access often takes precedence over deploying advanced 5G networks that might initially only serve a small, affluent urban segment.
Detailed Explanation
In LMICs, efforts typically focus on expanding access to basic mobile connectivity rather than implementing advanced technologies like 5G. The immediate goal is to ensure that underserved populations have access to basic internet services. This often means that resource allocation favors expanding existing 3G and 4G networks to reach more users, delaying more advanced networks like 5G which may not yet be a priority for the majority of the population.
Examples & Analogies
Imagine a community where many families lack electricity. Before building a fancy community center, the priority would be to get electricity to those homes so people can live comfortably. Similarly, in LMICs, making basic connectivity available is more crucial than introducing advanced technologies like 5G that cater mainly to a small portion of the population.
