Went to Lowyat to fix my phone. Surprisingly the 5G speed is way slower than 4G+ despite repeating conducted the 5G speedtest
We really need another 5G network in cities to free up some of the DNB capacity
Theory A:
The area is getting congested which is happening because the lack of base station densification.
Theory B:
The device is only connected to DNB 700MHz low band which in theory can only receive 50Mbps - 100Mbps of speed which is what the Speedtest has shown.This is just my assumption and theory. What happen is CelcomDigi have a bit of densitification than DNB in that area.
If we see the map below, CelcomDigi have 2 base stations available while DNB have only 1 base station and it is a bit far and blocked by the building nearby which make the signal fading.
Also using lower frequency of 1.8Ghz, the device can do carrier aggregation using the band available in CelcomDigi.
There is a high chance that the device is also not even using DNB 3.5GHz but instead use 700Mhz only which have the typical speed of 50Mbps - 100Mbps in 20MHz bandwidth range. If my theory is true, you pretty much get almost peak b28 frequency capability.
The only way to confirm this theory is true is someone having rooted Android phone with Network Signal Guru installed and see the data itself or you/someone can move closer to the base station and see if you get higher speed that reach beyond 100Mbps. Using this method we can confirm if the problem is theory A or theory B.

Celcom base station

DNB base station
The solution in my opinion is for DNB to introduce more basetation closer to lowyat so atleast the n78 frequency can go through the building or maybe just build DAS inside lowyat building.

This is me just sharing brain dead oppinion. Since DNB is an MOCN. Getting 60Mbps speed in dense area is kinda impressive since it hold all of the telco capacity in 1 base station only.
Especially if we put in context that currently DNB is in "Phase 1" of just laying out the basic 5G coverage only and no densification is done yet.
Which in my opinion, already fill it roles greatly, now DNB just to put more base station and see how it goes.
