Hope dream comes true!

I just can't wait for LTE launch by local telco

batery quite an issue, even hspa+ signal also baterry drain like no tomorrow..

counting down.. few more days to go.. can't wait to see how are they going to market and sell it

well it will be just like 3g plan but price will be double I am assuming

Any selected Maxis users here who are doing the LTE trial run? How's the experience so far?

To me, with the launch of LTE, telcos will need to launch new packages which are much more expensive. Can't use the current packages (etc: 500MB, 1GB, 3GB) as it will be gone in no time since speed too fast liao

I got 4 LTE modem all capable of detecting LTE

But I am not selected to be in the trial run

The add on of LTE means more competition which is good to push our current fiber operator to reach at least 50Mbps

I don't think there will be a direct competition as one (fixed line) offers unlimited and the other (wireless) will always have a quota to it. Quota has always been an issue between consumers and telco players, and will always continue to be, not just here in Malaysia but world wide. AT&T and Verizon Wireless have launched their LTE network back in the states, with AT&T's max data plan at 5GB and Verizon at 10GB.

Need to be at least Maxis One Club member to be selected kua....and also Elite (means spending more than RM500/month.) Trial run has been going on for months already.

You got the point. I think Sprint offered unlimited quota buy for Mobile Internet only.
At least this can stop fiber from advertising as fastest, which they will work more harder to use back their fastest term.
Currently only selling point of fiber is their fastest in Malaysia slogan.

My family line got almost 10 number and spend more than 3K per month yet I am not selected.
Are you one of them

Is it under a single account? If yes, then should be selected. Well, you need to be staying nearby a LTE enabled site too for a start.... :-)
No, I'm not one of them, sad to say....neither do I have a LTE enabled device.

True that LTE and fiber are not direct competition.. But it all depends on how they advertise it.. Remember P1 'potong' marketing campaign..

What the trial users are experiencing now may be different when it's commercial, because once commercial, there will be more users and users will get less speed

You did not read the latest Wall Street Journal on applying tenders in Malaysia and how many felt that without bribes, they could never secure contracts? Never heard fo the Alcatel-Lucent case with TM before? How many are confident enough of securing tenders in Malaysia fairly without going undertable?

That diagram shows that with FDD-LTE using duplex channelling for separate channels on dn/ul, there can only be 6 simultaneous users, while TD-LTE can handle 12 users which is twice the amount of users effectively with the same frequency block width.

Now do you understand clearly what spectrum efficiency is all about?

I haven't come close to explaining the more advanced promising features of TD-LTE that FD-LTE can do.
TD-LTE can do MIMO Beamforming with channel reciprocity(single channel for both traffics) which FDD-LTE is still years behind in research due to its complexity of duplex channels.MIMO beamforming can easily give operators a boost in speed with TD-LTE in the near future that FDD-LTE will see trouble getting into.

and NO.They DO NOT have the same spectral effiency if competed against each other on the same spectrum blocks of equal width.
One gets to use the whole road for itself for both traffics of different direction while the other has to split it into 1/2 for different traffics.

At 2600 mhz , how far LTE signal will go from tower ?
P1 have trouble with wimax 2300 mhz coverage, YTL YES using gov school as base station.

There are 1800Mhz together i think

Yes is smart, very smart. Free internet for schools but get free base station site.

this is singtel 4G plan


n singtel blives 2GB is not s little s we used 2 think

This is by far the stupidest statement I ever read/heard from a person who claimed to be an RF engineer... Are you sure you're an RF engineer?

Like I said before, yes you are correct saying that TD can dedicate the whole spectrum for either download or upload.. But they will need to divide the time, e.g. Half of the time is allocated for DL and another half for UL.. (this is just an example, if course there are many TDD modes which provide different DL-UL ratios in a time interval.

Whereas in FDD.. Only half spectrum is used for DL and the other half for UL.. But they are dedicated 100% of the time..

Do you understand how resources work in LTE now?

Since i now doubt that you're an RF engineer.. I will explain in easier-to-understand form.. Imagine you have a 2-lanes highway in both direction, say Melaka to Johor PLUS highway.. So in total you have 4 lanes, which 2 going south and 2 going north..

1. If you divide the traffic by time, all 4 lanes are going south in 1 hour and the you change the direction all traffics are going north in the next 1 hour... This is how TDD works.

2. On the other hand, FDD is just like the normal traffic where 2 lanes always going north and 2 lanes always going south all the time..

So assuming the traffic is constant for the 2 hours... And if you do the basic maths, you will get the same number of cars reaching south and north for both scenarios.. And this is similar like spectral efficiency...

Can u understand now why I'm saying in term of resources, FDD and TD are very similar..

I agree with you there maybe bribes in our telco.. But you were saying in your previous posts that there were bribes on why FDD is more commonly adopted than TD worldwide... And this of course has something to do with ITU at international level, thats why I thought you worked with FBI

Added on December 29, 2012, 10:09 pmIt depends on the tower height.. The higher the larger the coverage...

But i'd assume all operators will reuse their existing sites, so you can expect more or less same coverage with existing service..

2600 MHz will have slightly poorer coverage than 3G 2100.. But LTE doesnt suffer cell breathing like 3G (3G coverage gets smaller as number of users increases).. Also LTE manages interference between cells better than 3G.. So I guess it would be more or less the same as 3G 2100MHz

As for 1800MHz.. This will of course give better coverage.. Lower frequency means lower penetration loss

We're u able to detect digi LTE network?

You are still not getting the point there.

If a spectrum block width is to be imagined as that of a highway with 4 lanes wide, then time will be the determinant of its efficiency for its usage.
Traffic was never meant to be symmetrical in both directions where in real world usage, people do downloading more than uploading most of the time.

Take for instance you have a PLUS Highway with one going southbound and the other northbound,

In the case of FDD-LTE, the since the establishment of 2 lanes each way, the north bound traffic may be idle at times but the southbound traffic might get congested during certain hours. Don't you think it's a waste of resources when the northbound lanes are empty at most times of the day while nothing can be done about it?

As for TD-LTE, where each direction is allowed each time, all 4 lanes can be used either way and if northbound traffic is low, longer time slots can be dynamically be granted for southbound traffic to ease the congestion. Most importantly, the main argument POINT here is that the "lanes(spectrum use)" are not put to waste during in idle/low traffic utilization.Thus, spectrum efficiency is brought up.

Technology superiority was never an issue in the silent trade war among nations even during the 2G Cellular war when GSM and CDMA competed years back. The CDMA technology was more efficient compared to GSM yet the latter prevailed because of the higher adoption rates and eventually used in most parts of the world. How good the technology itself is not enough to determine the success of a particular product.

Today, the FDD-LTE and TD-LTE war is also a result behind the clash of the East and the West. One will not try to support the other because of the patent royalties incurred and trade inbalances as a resultant. The Europeans do not want to buy the TD-LTE products because they fear ending up to pay the Asian while the Asians do not want to give the same royalty fees to the Europeans which inturn affect their telecom equipment sales revenues.

Added on December 30, 2012, 9:42 pmActually if TD-LTE and lower frequencies were adopted, the chances of ISPs offering flat rate unlimited quotas would have been higher due to much lower initial costs for investments.

TM and Jaring managed to do it last time with their Wireless Streamyx and Jaring Wireless last time with 450MHz proprietary CDMA tech from SOMA Networks. Very good coverage too with fewer base stations needed.

Australia NBN(on 700MHz) is using this strategy as well as Sweden by Net1 using CDMA EV-DO RevB on 450MHz to serve subscribers in the jungle/rural markets. Those areas will never be served with fibre since they are too remote for implementations.
Their governments felt that even rural fols should not be deprived of high speed internet even if they'll never be served by fibre so they plan to use LTE 700MHz to give them 100mbps internet.

back to the post where you asked about 20Mhz TD-LTE is as good as 2x20Mhz FD-LTE?
Nope, definitely 2x20Mhz FD-LTE is better than 20Mhz TD-LTE.
but, 20Mhz TD-LTE is of course better than 2x10Mhz FD-LTE in term of downlink only, but who knows we have many cloud apps and UL could be important as well.

In term of quality:
FD-LTE is better since it ensure a single user have enough fixed resource, this is better in maintain a stable and smooth connection especially voice/video call.
In term of capacity:
TD-LTE can flexible allocate resource depend on users demand that connected to same sector. The more users using traffic concurrently, the lesser speed for each users, since resource is divided evenly. It is like P1, more users using = lesser speed

In term of overall spectral efficiency, both almost the same, TD-LTE have TTG and RTG but not forget FD-LTE have guard-band as well.

So, my conclusion is about quality vs capacity. A operator can have both system as well depend on demographic and scenario, as long as chipset support both technology.

Tomorrow is the big day. Digi said they will make sure they are the first to roll out LTE. Lets wait and see. Only few hours left when the clock strikes 12
