As a UMB user, I am happy with that.

mcmc already relocated the 700mhz for 5g after open for public inquiry mah...

https://mcmc.gov.my/en/spectrum/consultatio...quiry-responses

those frequency u mentioned memang dah allocated for mobile/broadcasting. for precise allocation, u can check mcmc punya spectrum chart and spectrum plan.

.
Yes, you are right.

More detailed news about this from year 2020, .......

https://soyacincau.com/2020/01/01/malaysia-...cmc-assignment/ - 2020/jan/01 - Malaysia 5G bands announced, 700MHz & 3.5GHz allocated to one entity (= DNB1)

AFAIK, DNB1 launched with 5G NSA which could not use the allocated 2X30MHz Low Band 700MHz, ie only 5G SA can also use it.

Has MCMC allocated another Low Band 700MHz to DNB2, ie to U Mobile's 5G SA.?

yes, they most probably awarded the 2x20mhz bandwidth of the 700mhz spectrum too.

https://soyacincau.com/2024/11/01/mcmc-awar...ond-5g-network/

Thanks for the info.

.
So, DNB2 or U Mobile will have 700MHz (2x 20MHz block) and 3.5GHz (100MHz block) spectrum for it's 5G SA network which AFAIK gives a bandwidth capacity of 400Mbps for Low Band 700MHz and 2Gbps for Mid Band 3.5GHz or 3500MHz - to be shared by all it's 5G subscribers and 5G MVNOs.

In comparison, if 5G SA, DNB1 has 2x30MHz of the 700MHz band and 100MHz for the 3.5GHz band, which is 600Mbps of Low Band and 2Gbps of Mid Band.

AFAIK, a 5G cell tower can service about 5,000 active subscribers at the same time in that coverage area. At peak traffic hours in urban areas, the average speed for DNB2 will be as slow as 2,400Mbps/5,000 = 0.5Mbps = 4G will be slightly faster (3Mbps) in such a situation because each 4G cell tower can only service about 500 active subscribers at the same time. This will happen when there are many more 5G subscribers.
.

if umobile awarded 2x20mhz block of 700mhz, then dnb only can have the remaining 2x20mhz block, where 1x20mhz block now are used for nsa b28.

i guess mcmc and dnb haven't conclude how the 700mhz will be shared among all entities.

Thought both DNB and UM get 2x20Mhz? The 2X20Hz for DL and UL, so 400Mbps abit exaggerated… i think barely 100Mbps DL.

Remaining on 700Mhz if not mistaken use for digital TV broadcasting by Altel.

.
400Mbps is referring to bandwidth capacity, not download speed.

Eg a TM Unifi Fibre-optic cable leading to linked homes has a bandwidth capacity of 10Gbps (= 10GPON or XGPON technology) to be shared by about 50 home subscribers. During peak traffic hours with 50 active subscribers, each subscriber will still get average 200Mbps download speed, ie 10,000Mbps/50 = Fibre Internet is not subjected to network congestion during peak traffic hours in urban areas, unlike 4G/5G Internet.
....... But if there is only 1 active subscriber, eg during off-peak hours, theoretically, he/she can get 10Gbps download speed.

Actually abit different with fibre. LTE Bandwidth Capacity is download speed for a single user at the best radio condition possible with supported device of all the possible capabilities. Quite dynamic.

Even if assume very optimum (standing in front of the antenna holding the top 4G phone in market) how 20Mhz LTE can give 400Mbps? Is that even possible theoretically?

.
Fyi, .......

.... Maximum 4G Speed With LTE, LTE Advanced And LTE Advanced Pro

The maximum speed of 4G LTE networks depends on the network configuration. There can be various combinations of channel bandwidth (e.g. 20 MHz), digital modulation (e.g. QAM = Quadrature Amplitude Modulation) and MIMO configurations. LTE is more efficient than 3G technologies, and it also offers lower latency than 3G UMTS and CDMA2000 networks. LTE networks have seen various enhancements over the years including major updates like LTE-Advanced and LTE-Advanced Pro.

Using a 20 MHz channel with a 64 QAM digital modulation, peak speeds of up to 300 Mbps can be achieved for downloads and up to 75 Mbps for uploads. LTE-Advanced can support peak download data rates of up to 1 Gbps and LTE-Advanced Pro can provide maximum data rates of up to 3 Gbps.

The average 4G data speed is what you normally get on your mobile device, whereas the peak speed is the maximum data rate the network can theoretically generate. So, the peak speed of a mobile connection is the maximum data rate that can be extracted from the radio signal when using the highest possible network configuration. For example, with LTE networks, we can combine multiple channels through carrier aggregation, configure different levels of QAM modulation in LTE/LTE-A/LTE-A-Pro, and employ various antenna settings to get the maximum possible bit rate. ...

https://www.nokia.com/about-us/newsroom/art...tion-explained/ - 5g-carrier-aggregation-explained

4G LTE-A can give peak (theoretical) download speed of 1Gbps and this is done through Carrier Aggregation, eg U Mobile 4G LTE-A has Bands 8, 3, 1 and 7 for CA. Similarly for Low-Band 5G SA if DNB2 or U Mobile has >1 Band of 700MHz.
....... Note that 1X20MHz Band in the 700MHz frequency range gives a bandwidth capacity of about 200Mbps. 2X20MHz = 400Mbps. Maximum theoretical d/l speed on a single 5G Low Band is 350Mbps. .......

.... That said, with 4G and low-band 5G increasing steadily, the Cradlepoint 5G Strategy team estimates that peak speeds in the coverage layer could go as high as 350 Mbps, with maximum upload speeds of 60 Mbps, and latency in the 30 ms range. ...

There you go, DL 200Mbps as per the explaination in article for 1x20Mhz. If is not 700Mhz, it can go higher, low band has some have limitations.

The 2x20Mhz is for DL 20Mhz and UL 20MHz cause is operating in FDD. It is written that way for a reason (2x20Mhz instead 40Mhz)
So, is not 2x20Mhz= 40Mhz for DL only. So cannot multiply by 2 (this in the article is incorrect).

Or maybe the article add the up and down speed to get 350-400Mbps, which usually people dont say that … DL and UL usually mention separately not cumulatively. Quota GB usually will mention together but not the speed.

In the beginning all the 2x40Mhz given to DNB but gotta vomit back for UM in this case. Both DNB and UM shall receive 2x20Mhz each eventually.

.
No lah. Afaik, DNB1 got 2X30MHz block 700MHz in 2020 whereas DNB2/U-Mobile got 2X20MHz block 700MHz in 2024, from MCMC = if so, DNB1 will have a slight competitive edge over DNB2 wrt bandwidth capacity, ie 2.6Gbps vs 2.4Gbps
.

as far as 700MHz assignment could go, both DNB and U Mobile now own 2x20MHz. Even the DSS n28 on DNB now reusing the same chunk of B28, which is why SA 5G is not that important in Malaysia.

.
Maybe DNB1 is keeping a 2X10MHz block 700MHz in reserve for later deployment.
.
Why is 5G SA not that important in Malaysia.? Note that later, MCMC can refarm to DNB1 & 2 some of the Low-Band 4G 800MHz and 900MHz for 5G SA, thus increasing their Low-Band bandwidth capacity to about 1Gbps through Carrier Aggregation. 5G SA Low-Band has much better range and object penetration that Mid-Band/3.5GHz.
.

You should know there's almost no UE in the market can do low band CA right, not even iPhone

I think if telco was allowed to build own 5G they would have CA their own LTE bands + 5G to deliver much higher speed and much stable network. And over time refarm their LTE to make 5G more powerful. That was the original technology evolution of 5G … until some Malaysia ministers come up with SWN idea and cause havoc in Msia mobile industry. Consistently DNB 5G will have data stalling that need to turn of 5G to use mobile data - such troublesome experience.

Hope UM can bring Msia 5G back on track with the right 5G implementation. Sorry to say but i think Maxis and CDB will sink together with DNB.

.
AFAIK, Apple is a newcomer in producing their own 5G modems, ie the C1 and C2 modems, for their latest iPhones. That may be why the latest iPhone 16 does not support Low-Band 5G SA Carrier Aggregation.

For our info, .......

.... The first test used a commercially available Samsung Galaxy S25 with the Snapdragon® X80 5G Modem-RF System running test software, leveraging T-Mobile’s industry-leading 5G network to reach downlink speeds of 4.3 Gbps in real-world conditions. In a second test, offering a glimpse into the next evolution of 5G Advanced, T-Mobile pushed the boundaries even further by leveraging the brand-new Qualcomm X85 5G Modem-RF on a mobile test device, achieving peak speeds of 6.3 Gbps.

Both tests combined low-band and mid-band spectrum on the Un-carrier’s 5G Standalone (5G SA) production network, delivering blazing-fast performance. To put these mind-blowing speeds into perspective, you could stream every Super Bowl ever played in 8K resolution—simultaneously. Once again, the Un-carrier sets the standard in 5G innovation.

“With 6-Carrier Aggregation, we’re not just adding another feather to our cap—we’re accelerating the future of 5G Advanced,” said Ulf Ewaldsson, President of Technology, T-Mobile. ...

= CA can even be done by combining Low-Band and Mid-Band in 5G-Advanced by using Qualcomm X80 and X85 modems. I believe CA can also be done by only combining 2 or more Low-Band 5G SA. Eg USA's T-Mobile has Low-Band 5G SA at n71/600MHz and n25/1900MHz.

I think he meant Low Band and Low Band CA not supported. Thats why 700,800 and 900 CA are challenging.

Maxis and CDB would not want to be controlled by a smaller company called U Mobile. At most, they could enter into agreement to rent the second network in places where DNB do not perform well.

true, throwing bunch of text does not mean they are correct. So far only Sony can do low band with 4T4R, I'm not too sure about CA. But as far as I know, no commercial device support low band CA yet.

Which is why most telco in another country will only have 2 low band at max. One deploy 4G, another deploy 5G.
