SA theoretically should have better coverage and faster speed compared to NSA because NSA runs on 4G Core Network
But here’s the thing, DNB is built on a brand new core network and then connected to telco core network
Nowadays if you noticed many telco 4G ping on a fiber-ed tower is quite low (16-18ms), means telco 4GC is actually quite good already
Thus it doesn’t really make big difference for SA vs NSA at least for DNB, the only thing I noticed is SA will provide better coverage on N28 because when in fully SA the 700MHz is running on NR, which provides beam capability and thus the network coverage is more wider.
Since all the underlaying bandwidth are the same, it shouldn’t make any huge difference like additional 200Mbps+ speed unless the telco do network slicing on the SA network which makes your device the priority one (refer to Yes 5G Network Slicing Test), where this means others user on the same network will be deprioritised as they share the same spectrum
Correct me if I’m wrong and no the signature photos is from a public area
the 4G core network aka EPC is what ultimately decide the speedtest result. as all RAN converged to EPC and processed there. so the
RAN---Transmission---EPC, the entire bandwidth from RAN to EPC is deciding factor.
as you know, the current setup, B28 LTE anchor to 5G NSA is because reuse of LTE RAN (eNodeB) to connect to DNB core network (aka Ericcson's 5GC) this is the most economical ways of 5G implementation.
I think it will be long road before we can have 5G SA, as LTE eNodeB is still making up most of the RAN equipment with years of deployment.
Those who wanted 5G SA, the bestest way is jump on the bandwagon of UM ultra5G. single vendor, Huawei for West Msia, ZTE for E.Msia.
I don't know much about YES, UM and YES are consider smaller players, hence their own LTE deployment is not as wide and big compare to big Three. so it make sense for them to jump straight to 5G full deployment without the 4G deployment cost baggage.
the advantage of 5G SA are uMBB , mMTC , URLLC and Network slicing,
in simple term
uMBB = speed + capacity.
mMTC = connect millions of small IoT devices efficiently
URLLC = real-time + ultra-stable connection.
