Singapore 5G frequency bands

[Kepller]

https://en.wikipedia.org/wiki/List_of_5G_NR_networks

Based on the above source, the 5G frequency bands in Singapore are:
N1
N78

Singtel Wiki Page:
https://en.wikipedia.org/wiki/Singtelhttps://en.wikipedia.org/wiki/StarHub
Seems like they are both primarily using N78 and nothing else, Singtel is the only one using an additional N257, but what does Commercial-non standalone mean?

If I were to purchase a phone which have the following bands would it face problems with 5G here?

5G: n1 / n3 / n28 / n41 / n77 / n78 / n79
Note: The actual network and frequency band usage depends on the deployment of local operators
4G: FDD-LTE: B1 / B2 / B3 / B4 / B5 / B7 / B8 / B12 / B17 / B18 / B19 / B20 / B26 / B28
TDD-LTE: B34 / B38 / B39 / B40 / B41 / B42
Note: LTE B41 (2496-2690 194MHz);
3G: WCDMA: B1 / B2 / B4 / B5 / B6 / B8 / B19; CDMA EVDO: BC0
2G: GSM: B2 / B3 / B5 / B8; CDMA 1x: BC0
Support 4×4 MIMO antenna technology | HPUE | HO RxD

Would this basically mean as long as our new 5G capable phones supports N78, we'll be all set for 5G in SG? Or will there be additional new bands showing up and being used by the Telcos in the future?

SingTel/M1/StarHub/TPG are all issued mmWave on 26GHz and 28GHz band. It's likely n257 and n258. Coverage for those signals is few and far between; superfast but can't even a few metres can lost the signal.

In the future, more bands might be refarmed for capacity and coverage. This is standard practice, as operators slowly wind down on legacy networks to make sure current gets faster.

But based on current spectrum availability for the four carriers, it should be fine.

Band 1 / n1 (FDD 2100 / IMT) is in use for Big Three's 3G and 5G now. (TPG's bet for 5G is now on this band)
Band 3 / n3 (FDD 1800 / DCS) is in use for Big Three's 4G now, but might refarm for 5G as well (using DSS).
Band 7 / n7 (FDD 2600 / IMT-E) is in use for Big Three's 4G now, less likely to use as 5G as it is the capacity band for 4G, at least for the foreseeable future.
Band 8 / n8 (FDD 900 / EGSM) is in use for 3G and 4G now, spectrum isn't enough for 5G anytime soon. This is the coverage band for all 4 carriers.
Band 28 / n28 (FDD 700 / APT) was supposed to be used for Big Three's 4G as coverage band, but is much more likely to be 5G for coverage band instead. Reason: Indonesia's timeframe for analogue TV shutdown has been delayed repeatedly, now slated for November 2022.
Band 38 / n38 (TDD 2600 / IMT-E) is currently owned by SingTel/StarHub/TPG, for use on 4G. Might be used for 5G as another mid-band alternative.
Band 40 / n40 (TDD 2300 / S-Band) is in use for TPG's 4G network. They might use this for 5G as well (using DSS).

Band n78 (TDD 3500 / C-Band) is in use for Big Three's for 5G. Might migrate to n77 (TDD 3700 / C-Band) when co-channel interference reduces in the region, adding more capacity for the operators and potentially issue some spectrum for TPG.
Band n257 and n258 are all used for mmWave, all 4 carriers won the spectrum almost for free. Coverage is very limited, so do expect most implementations to be inbuilding instead.

Interesting, does it mean that if B38 (4G) is in operation then N38 cannot exist until B38 is converted into N38 (5G)? Basically they both run on the same frequency but at different bandwidth so only one of them can exist? Or both N38 and B38 can exist at the same time, just that if the phone only supports B38 and not N38, in a location where there's both N38 and B38, the phone will only receive B38 (4G)?

If a 5G capable phone such as the Mi 11 Ultra (China) supports B38 (4G) but not N38 (5G), when B38 is converted to N38 in Singapore, the phone will not be able to receive N38 (5G)?

If my above understanding is correct, than that means the Mi 11 Ultra (China) version might not be fully 5G ready in SG as the only bands it has that is 5G capable and which Singapore uses is N78 and N1, should B38 be upgraded to N38 there'll be a missing frequency range the phone would not receive, which will result in less 5G signal coverage.

Based off the spec sheet of the Samsung S21 Ultra (SG set), it does not indicate the N257 and N258 bands. This means it might also not be fully 5G ready. I'm not sure if there are any mobile device at present which supports mmWave, but if the flagship S21 Ultra lacks this, there might be no existing phones with these bands. If so, its a pretty tricky time to purchase a flagship device. If 5G implementation suddenly begins to ramp up, the current phones might get outclassed by newer ones with support for the mmWave bands though on a quick read, it seems to be pretty new high-end tech, it might not be widely adopted that rapidly.

As we see, implementations have to vary across different demographics due to other considerations - what's good for China/S. Korea may not be good for us due to the differences in frequency band deployment. And there will be differences due to various applications, military, civilian, commercial, governmental, etc... We cannot reasonably demand for those entities to switch out at whim just to deploy a new network band; even if they agree, they need a reasonable period of time and a capital expenditure to do so - perhaps a year or more to replace equipment.

If you recall 4G phones, no first-generation phones were fully 4G ready. In fact, there were regional chipsets as they had to make multiple variants of a phone for different markets based on their implementations. This is the early adopter's penalty, along with the power inefficiencies of the relatively new technology. It will get better over time, but if we base it on the general observed trend, it's probably the third or fourth generation of chipsets (ie, 3-4 years) before it becomes stabilised somewhat at more acceptable normals and more universal in band support, such that it has trickled down to low-midrange chipsets. This is when we expect the technology to be more mainstream - when your budget phones and devices have a more universal 5G support across various borders the way it is for 4G today.

In fact, I'm anticipating the deployment to take longer, largely due to the much higher capex for telcos to deploy 5G when compared to previous mobile technology. Right now, it becomes a chicken-and-egg issue, since you need more phones and you need a ready network, and both are interdependent factors in the deployment process. For me personally, 4G still suffices for now. Perhaps I'll only switch in future when more 4G bands are refarmed and coverage is greatly reduced to the point of being inefficient, or when 5G SIM-only plans start to approach similar price points to today's SIM-only. For now, I don't feel that it's worth it to pay the early adopter's penalty for speed gains that are not revolutionary or change anything I do.

The Telco can splice up their available spectrum lot for multi-generation implementation, as long as it meets the minimum requirements set by ITU.

Conventionally, legacy networks (GSM/3G) has to be carved a specific bandwidth to operate. For example, 900MHz spectrum for SingTel, they have 2x10MHz spectrum. 2x5MHz is used for 3G, another 2x5MHz is used for 4G.

However, with 4G/5G, as it's all IP implementation, DSS can be used. Basically, the spectrum lot that the Telco bid can be used to run 4G and 5G concurrently, no splicing is needed. However, it can cause some sort of speed degradation, depends on the timing that each generation is given.

So for your question for B38/Bn38 implementation, due to the fact that it's for LTE (4G) and later technologies only, it'll probably be using DSS instead to share bandwidth with 5G.



Honestly, mmWave implementation is really tricky and expensive, both to the device manufacturer and network operators. Battery life could be trash too since the device have to constantly boost signal to find the mmWave signal and to maintain that connection. It's a good to have technology, but only in places with a huge need for capacity, like stadiums and malls.
However, let's be honest, now with COVID-19, what's the chances where you'll go to those places anytime soon, even if the government allows?

Some updates (this post is highly ranked on Google so for those of you just coming in, this may be relevant):

Band 1 / n1 (FDD 2100 / IMT) is being used by all 4 telcos (including TPG) for 5G (and some 3G service)
Band 3 / n3 (FDD 1800 / DCS) now supports 5G (NSA) using DSS on the Big 3.
Band 7 / n7 (FDD 2600 / IMT-E) and Band 38 / n38 (TDD 2600 / IMT-E) might be combined into Band 41 / n41 (TDD 2600 / BRS), as IMDA has shown interest in doing so. There may be 5G service on n41.
Band 8 / n8 (FDD 900 / EGSM) now supports 5G (NSA) using DSS on StarHub only.
Band 40 / n40 (TDD 2300 / S-Band) is no longer used for TPG's 5G. They are instead deploying an SA network on n1.

5G NSA is operating on these bands now:
SingTel - n3 (DSS), n78 (fastest)
StarHub - n3 (DSS), n8 (DSS)
M1 - n3 (DSS), n8 (DSS)
TPG - N/A

5G SA is operating on these bands now:
SingTel - n1, n78
StarHub & M1 (Anita) - n1, n78
TPG - n1

I found that my Xiaomi 11 is on the 5G SA supported list for Singtel, but not supported for StarHub and M1.
But I check GSMArena all band 1, 3, 8, 78 are supported?
And same goes to iPhone 12 series don't support 5G SA in singapore, must have at least iPhone 13 series. And it's too bad that M1 has shut down their NSA network. But iPhone 12 i check also band 1, 3, 8, 78 are supported??

There are multiple variants of the iPhone with different hardware configurations to support different geographical locations - check the phone's model. Chances are you are looking at the US variant, as they had 5G enabled for them.

In addition to supporting the network bands, the telcos have to enable 5G support for each individual phone and model.

There is a workaround for Xiaomi devices on MIUI

sigh, meaning if the phone model is not on the telco's (i wd say) exhaustive list, then no point in checking the phone on hand has the necessary bands not, as the telco has not enabled support for that particular model

Yes, EXCEPT for Xiaomi phones, which can bypass the whitelist and enable 5G SA regardless of whether the telco has validated it, as long as the phone supports the band.

 

[potatohead]

Yes, EXCEPT for Xiaomi phones, which can bypass the whitelist and enable 5G SA regardless of whether the telco has validated it, as long as the phone supports the band.

Thanks for the info. I got a Redmi K30 Pro flashed to to Poco F2 Pro firmware (exact same hardware), it has band n78 SA support, which is the band used by M1/Starhub, and I have enabled SA using the info you provided a few posts back. I will be getting the M1 SA 5G SIM these few days, will post back here with the results

 

[potatohead]

Yes, EXCEPT for Xiaomi phones, which can bypass the whitelist and enable 5G SA regardless of whether the telco has validated it, as long as the phone supports the band.

unfortunately i couldn't get my redmi k30 pro flashed to poco f2 pro firmware to connect to m1 5G SA on band 78 even though the SA option has been activated and checked for use on my k30 pro.

i was in town today and when the same sim was inserted into a local oppo find x3 pro, it immediately detected m1's 5G network and connected to it (oppo find x3 pro is on m1's official list).

of course there is always this possibility that the above happened because my phone has cross-flashed firmware, though I have my reservations as both models share the exact same hardware and band 78 SA support was natively factory activated for both by Xiaomi / Qualcomm.

my guess is telcos' supported hardware lists are not exhaustive as there are simply too many 5G phone models on sale locally through official channels, however, for 5G to work on a phone, telcos still need to whitelist that model on their end. in other words, 'permission' was granted but not public announced / made known.

if one wishes one's next phone purchase has confirmed 5G support in SG, other than buying a so called local set, it will be prudent to only buy those models that are also sold by telcos; in the rare event that such phone cannot connect to the telco's 5G network, they will most willingly whitelist that model as it is an obvious mistake on their end, whether you have bought your phone from them is irrelevant.

Just wondering if the telcos here have an updated 5G phone support list or not.

1) Singtel's list seems to be quite outdated (the date is 06-Jan-2022).
https://www.singtel.com/content/dam...vices/mobile/5g/Singtel 5G FAQ_060122 v40.pdf
Their 5G prepaid list is slightly different.
https://www.singtel.com/content/dam...es/mobile/prepaid-plans/5g/prepaid-5G-FAQ.pdf
For example, we have Realme X50 5G and Realme 7 5G at home. Realme X50 5G is only listed in the prepaid 5G list. Realme 7 5G is listed in the main 5G FAQ PDF. Both of them are listed in the Starhub 5G phone list.

2. Starhub list is also not really up to date.

Which 5G devices are compatible with StarHub’s 5G?
Below is the list of 5G devices that you can enjoy StarHub’s 5G service. You can look forward to more handset manufacturers coming on board. Do stay tuned to this page for updates.

2. Starhub list is also not really up to date.

Which 5G devices are compatible with StarHub’s 5G?
Below is the list of 5G devices that you can enjoy StarHub’s 5G service. You can look forward to more handset manufacturers coming on board. Do stay tuned to this page for updates.

3. M1 information is not very clear
https://www.m1.com.sg/support/faq/5g-sa-faq (only iPhone 14 and Galaxy S22 mentioned)
https://www.m1.com.sg/blog/personal/why-and-how-5g-will-change-everything (very outdated list).

looking at the dates, I doubt any of them are updated.

for M1 and (maybe Starhub; as they shared the same 5G infrastructure), the change is even more drastic as between now and early this / last year they have moved totally to SA network, completely shutting down the NSA facilities, 'official' phones that work on M1's 5G then may not work now if they don;t support 5G SA.

i m not network engineering trained, i just hope this 'telco-need-to-whitelist-phone-model' trait of 5G networks is just due to the fact that telcos are still rigorously testing their new networks, they want to minimize uncertainties, thus only certain phone models are allowed to connect, once the networks are certified to be matured, situation will be like 4G whereby any phone that supports the telco's bands can connect, of course, VoNR may be another story altogether like VoLTE

the above scenario should be very likely if there are no absolute engineering reason why it cannot happen, as more than 90% of phones released by any and every brand now supports 5G and new ones are popping out every other day, for the telcos to keep track of new model releases and whitelist even half of them will take tremendous amount of effort, not forgetting SG is also an international hub with substantial number of foreigners, both visiting and working here, carrying their 'non SG' 5G handsets.

as above, for now if one wishes to ensure one's new purchase will definitely work on the telco's 5G network, just buy the model which the telco is selling, not necessarily from them directly due to pricing but must be a so called local set with local manufacturer or distributor warranty (in other words, exact model as what the telco is selling)

for budget android users, pity it will mean very limited to no realme, redmi or poco 5G handsets, models by these brands often offer lotsa bang for buck.

for iphone users, to get 5G SA on M1, you will need a phone 13 and above, 12 only supports NSA; Singtel claims its network on band 78 is a hybrid SA (presumingly with NSA), not sure if officially supported non SA 5G handsets are able to connect not

SingTel n78 is hybrid SA/NSA, although speeds can be VERY SLOW if you're using NSA only.

VoNR actually works by compatibility and not whitelist - I got 5G SA + VoNR working on my Xiaomi 11 Lite 5G NE despite M1 officially only supporting Samsung for VoNR.

how does one check for VoNR? on Oppo phones, the connected voice network type does not show in Settings About Phone

i guess as you have said, VoNR is not supported on Oppo phones by M1 atm, even on 5G, the VoLTE icon is on and when making calls, the network switched to 4G+, a clear indication

btw, how is the power consumption of your xiaomi 11 lite 5g ne (SD778G / X53) like when connected to m1's sa 5g? on my oppo find x3 pro (SD888 / X60), i can literally see the battery level falling 1% every few mins even when the phone is in standby or under light usage, and that is in town, just by being connected to 5g, pretty ridiculous ...

also wondering about the real life power consumption of the SD8G1 / X65 combi and Mediatek's Dimensity 9000 and 8100 SoC with their R16 5G modem on local 5G if you have any idea, MediaTek claimed to have UltraSave power saving mode on these SoCs

My Poco F4 GT works on M1 NR SA network but not VoNR....
