Our earlier uncovered story defined the misconceptions or false narratives surrounding the 700 MHz band. We concluded within the story that different facets could be mentioned in a special report, so let’s look into yet one more side now. One other false impression or false narrative that’s broadly in circulation is about 5G NSA and 5G SA. So on this story, we tried to clarify the identical in Layman’s phrases utilizing examples that anybody can perceive.

Excessive-level Structure of 5G NSA and SA Deployment
The picture above offers a high-level overview of the 5G Non-Standalone and 5G Standalone Deployments.
The high-level deployment setup includes of
- Core – EPC, 5GC
- Radio – LTE, NR
- UE – Consumer Gear
Let’s talk about Radio, UE and Core on this order.
1. Radio
Radios are communication tools that hyperlinks the customers’ gadgets to the Mobile Community wirelessly. The above deployment architectures use LTE for 4G and NR for 5G. If you happen to observe in each NSA and SA, Radios should be deployed. A section which typically takes time for the telcos to rollout the companies. So, Airtel must deploy 5G NR Radios identical to within the case of 5G SA. Airtel already has LTE Radios deployed for its 4G Community and is at the moment deploying NR Radio, identical to within the case of SA, to ship 5G companies. Therefore, this side is similar for NSA and SA.
Bear in mind the profit Airtel has to deploy fewer Radios as a result of Spectrum Technique adopted by the telco.
2. Consumer Gear (UE)
Smartphones, Dongles, and Gadgets related to the respective Community (4G, 5G) are represented by Consumer Gear (UE). Merely put, UE is any smartphone or gadget that connects to the Community. As a variety of handsets helps NSA, Airtel can ship 5G expertise to hundreds of thousands of its customers with out leaving the bulk to attend for an replace or purchase a supported handset. Contemplating its current consumer base and market situation, Airtel should take each of its buyer alongside whereas safeguarding the traders’ pursuits and future-proofing Networks for the CAPEX concerned.

If we think about SA, the handset ecosystem must evolve, which is why fewer supported gadgets exist— not speaking about gadgets that already help SA. So, the (Consumer Gear) UE part of the structure has nothing to do with a telco. A Core purpose why Jio is taking time to make sure help for a spread of handsets.
Now, the one factor left from the Structure is the Core. So, if we’re speaking about 4G Networks, it’s EPC (Advanced Packet Core), and if we’re speaking about 5G, it’s 5G Core (5GC).
3. What’s 5G Core (5GC)?
The 5G Core is like the guts and mind of the 5G Networks. The 5GC acts as an enabler for next-generation networks. The Core consists of a Knowledge layer, Management airplane and Consumer airplane. The Core is a Service Based mostly Structure (SBA) that drives, and implements the standard of service, enforces coverage, Authentication, Signalling, Analytics, Gateway features and so on., and every little thing associated to the networks and functionalities for 5G.
In 5G, the core community has developed as cloud-native and may run as a scalable setup in virtualized environments. 5GCore includes a number of features that run as particular person microservices which might scale as per wants. These features additionally ship 5G SA functionalities like Community Slicing, Extremely Excessive Speeds, low latency, Enhanced Safety, Community Publicity features and so on.
The complete 5G system contains eMBB (enhanced Cell Broadband), mMTC (large Machine Kind Communications), URLLC (Extremely Dependable Low Latency Communications) and so on. 5G Core has benefits in comparison with superior EPC to be used instances that aren’t so broadly used from a client perspective, corresponding to VR, AR, IoT, Community Slicing and others. 5GC is able to delivering excessive capacities as a result of improved functionalities within the system. So, when a telco sees demand for a selected function 5GC affords, it could actually change to 5GC at any time limit nonetheless they need, as every little thing is already prepared.
Merely put, the 5GCore can run within the Cloud, corresponding to personal Cloud, Google Cloud, AWS or any cloud of selection by the telco. You’ll be able to learn one such a narrative from the under hyperlink.

Sure, it’s the similar, and a telco with NSA can do that at any time limit each time it thinks the use instances and Market are appropriate for Enterprise. So why not now? It is determined by how a telco sees the Market Dynamics, International headwinds, and Return on Investments and has nothing to do with its Community Capabilities.
Instance:
As 5GCore is complicated for a basic consumer, the under layman’s instance will assist you to perceive, however not a precise technical as is comparability.
- To illustrate your Newest Laptop {Hardware} as New Radio (NR).
- Notepad 2022 is EPC.
- Notepad 2023 is 5GC.
There are options that the 2023 model delivers, corresponding to quicker entry, safety and so on. So, everytime you see a necessity for such options, you’ll improve to Notepad 2023 by way of Cloud, and there you may have it. Equally with 5GC.
NSA vs SA
In each instances, the numerous distinction you’ll be able to discover from an architectural perspective is 5GC (5G Core), and the remaining stays the identical apart from some upgrades which are vendor particular. Now that issues are apparent, it’s as much as the logical reasoning of a person on how they take a look at NSA or SA.
Benefits of NSA in contrast with SA
The benefits of NSA are telco-dependent primarily based on the present spectrum holdings, which is completely different with each telco. That is the place Airtel has a singular benefit relating to its spectrum holdings within the context.
1. As seen from the Structure above, in SA mode, 5G comes on prime of the 4G Layer, and each act independently, which has two disadvantages within the present situation.
Gadgets: Lack of a well-developed gadget ecosystem for SA gadgets.
Spectrum and Propagation: The 3300 MHz band, the workhorse layer that delivers 5G Speeds, has much less propagation than the 2300 MHz band, impacting protection in city areas. Because of this, 5G SA wants a Sub GHz layer (700 MHz) to work in tandem with the 3300 MHz band, but it surely ought to be famous that 700 MHz is for protection and never a capability band. At finest, the 700 MHz band can ship 4G like speeds round 8-10 Mbps, present protection indoors and in far-flung areas, and nothing extra, which isn’t what a buyer expects from 5G.
However NSA deployed by Airtel has this benefit the place the 3300 MHz band acts as a Downlink, delivering 5G throughputs and the mid-bands (1800/2100) – the 4G layer caring for the uplinks, extending protection in City areas.
2. Airtel can leverage current 4G infrastructure at no additional price because the setup is prepared and already out there. Regardless of buyer handset compatibility, customers can take pleasure in 4G or 5G.
3. Airtel’s robust Mid-band spectrum holdings are a purpose for this distinctive benefit of 5G NSA. Because the competitors doesn’t have sufficient mid-band spectrum, there isn’t any selection other than the 700 MHz band. So this leads to a requirement for large-scale SA deployments and Radios, which require heavy CAPEX. A core purpose why Jio’s Radios are extra in quantity in comparison with Airtel’s as just lately reported by Ministry of Communications.
Airtel is at the moment putting in a mean of two radio transceivers on each tower to broaden 5G protection, whereas Reliance Jio is putting in as much as six as per a Enterprise Customary Report.
4. The NSA benefit is round expertise, the place Airtel customers can take pleasure in a quicker name join time on Voice. As well as, it permits a quicker uplink than anybody else, as Airtel holds a large mid-band spectrum.

Deployment Choices
There are a number of deployment choices for Communication Service Suppliers (CSPs), as not everybody begins from the identical level. For instance, a brand new telco might begin from scratch, some desire a hybrid mannequin (using current infrastructure), and a few telcos look ahead to Market Dynamics and ROI. So, all of it is determined by the optimum utilization of assets whereas getting funding returns and future-proofing networks.
So, 5G NSA and SA coexist for sure years, and 5G SA alone (case 3 from picture) can not exist as each telco has obligations to help roaming, a variety of handsets and so on. Furthermore, numerous Community Distributors have a number of choices and modules for deployment primarily based on the proprietary tech they’ve developed as per 3GPP specs. So, the above-discussed situations might have slight variations primarily based on vendor or telco.
Conclusion:
Nowhere on this planet can we see such a state of affairs as in India. 3GPP consortium developed 5G NSA and SA specs to make sure a easy transition to Subsequent Technology Networks. They should have by no means anticipated this might create circumstances for driving false narratives of unique advantages or capabilities for any particular telco. Finally, it is determined by a selected telco, enterprise selections, market of operation and the way a telco needs to evolve. Now that you recognize the distinction between 5G NSA and SA, we’ll talk about different facets in a special story.
