Why DiGi Signal is Terrible Weak when You Are Indoors ?

DiGi subscribers, have you ever experienced terrible weak signal especially when you are indoors? It’s even worst during raining. Have you ever think WHY?

Before I explain it to you, let me tell you some introduction and basics.

Malaysia is having 4 telcos, they are Celcom, DiGi, Maxis and U Mobile, and 3 frequency range are available – GSM 900, GSM 1800 and UMTS 2100. UMTS 2100 is 3G. Out of these 4 telcos, only DiGi is using GSM 1800 while other telcos are using GSM 900. But of course all of them are using UMTS 2100 for 3G services.

So, DiGi is the only 1 telco in Malaysia using GSM-1800, and DiGi is also the most complaints about poor or even terrible weak indoors signal. Now, can you related this problem with it’s GSM 1800 ?

What is GSM 1800 ?

According to wikipedia, GSM-1800 uses 1710–1785 MHz to send information from the mobile station to the base transceiver station (uplink) and 1805–1880 MHz for the other direction (downlink), providing 374 channels (channel numbers 512 to 885). Duplex spacing is 95 MHz. GSM-1800 is also called DCS (Digital Cellular Service) in the United Kingdom, while being called PCS in Hong Kong (not to mix up with GSM-1900 which is commonly called PCS in the rest of the world).

Another article from wikipedia — Generally speaking, lower frequencies allow carriers to provide coverage over a larger area, while higher frequencies allow carriers to provide service to more customers in a smaller area.

Another not wikipedia articles we found — As the frequency increase its penetration power decreases.The signal travels a lesser distance.Hence for a perticular area more no of towers need to be erected in 1800/1900 than in 900MHZ for full coverage…Hence vodafone( 1800MHZ) has more towers per unit area than Idea Cellular ( 1800+900) …..

Band of 900 is from 890-915( uplink) 935-960Mhz( downlink)….
Band of 1800 is from 1710-1785(uplink) and 1805-1880MHZ(Downlink)….

Same property is followed here…..The uplink is lower ( MOBILE -BTS) than the downlink frequency (BTS-MOBILE)…so that this may help the uplink signal to travel futher without consuming much power…BTS due to its increased power ,has higher frequency to tavel the same distance…

A long conversation with DiGi 2nd level support team, he told me that, because DiGi is using GSM 1800, so the coverage is wider than GSM 900, that’s why we can see DiGi slogan said they are having the widest coverage, although we all know that DiGi coverage is not as wide as another 2 telcos – Celcom and Maxis.

He also said that, the only disadvantage of it is the GSM 1800 penetration is poor, so signal become weaks when indoors.

After the conversation, I did a lot of search, all mentioned that GSM 1800 coverage ain’t wider than GSM 900, and also does not tend to propagate better through buildings due to the wavelength is close to the atomic seperation of the atoms making up the brick.

So many disadvantages of GSM 1800, why DiGi loves GSM 1800 ?

No idea, may be due to GSM 1800 is capable of faster data speeds, and also able to provide service to more customers in a smaller area.

Conclusion

Now, do you have any idea why DiGi signal is terrible poor indoors ?

Recommendation

  • If you care about every minute few cents cheaper than other telcos
  • If you ain’t encounter this issue
  • If you’re happy with DiGi services
  • If you’re enjoying unlimited free voice call + sms among supplementary lines
  • If you don’t mind this signal issue
Then we recommend you stay back with DiGi. But if you’re businessman, every single call drop could probably make you lost money, then you should start considering…

  • On the day of your birthday and the next 6 days you can enjoy Free SMS & Call to Celcom favorite numbers.

Strongly recommend for colleague or university students from age 18-25 years.


Exec 20

Generally we don’t recommend Exec 20 to our RMvalues supporters. If your monthly usage is less than RM 50, then prepaid is your choice, if you use over RM 50, then just go for postpaid commitment plan. Nothing is cheap with this Exec.

Monthly you have to pay RM 20 only for access fee under this plan. Call, SMS, MMS & other services will be charge accordingly. So your monthly bill will be :

[ RM 20 (Access fee) + Usage ( Call, SMS, MMS, IDD, Roaming, Data charges ) ] x 5% government tax + RM 3 (itemized bill) = Minimum RM 23.

Not worth for you to have this Exec 20.

Exec 50

The more you use, the more you save. You will enjoy usage discount if you use over RM 60 per month.

If monthly you make around 2000 minutes voice call without or very rarely sms/mms and do not use Data services, then Exec 50 is your best choice.

2000 minutes voice call x RM 0.15 = RM 300

RM 300 – 30% disount = RM 210

If you make call over 2380 minutes monthly and send over 50 SMS monthly, then you should go to the next plan Exec 250.

Exec 250

If you are frequent internet user and make around 2000, then Exec 250 is your choice.

If you use Exec 50 + Advance Data Plan and monthly call around 2000 minutes, then you will have to pay RM 308 per month. Why ? Look here:

RM 210 (after 30% discount for 2000 minutes call in Exec 50) + RM 98 (Advance Data Plan) = RM 308.


Phone Plan

If your monthly bill is over RM 148 for Exec 50 or you are using Exec 250, and would like to buy a cheap phone, then Celcom phone plan is your right choice. Otherwise you should not go for phone plan as their commitment is quite high and not worth to go if your monthly usage is low.


Data Plan

If you don’t care about the speed, then Weekly Unlimited plan is the best choice for Prepaid subscribers.

Entry plan is the choice for postpaid subscribers who are not really care about the extreme low speed but wants to enjoy low rate.

Basic plan is the choice for postpaid subscribers who are moderately care about the speed but don’t want to spend too much for it.

Advance plan is the choice for postpaid subscribers who want high speed and don’t care about the price.

Pay-Per-Use is the choice for prepaid and postpaid subscribers who want to enjoy the high speed but rarely use it or who want to enjoy the high speed and unlimited usage. Because Basic & Advance plan only limit to 5GB monthly usage. Speed will be throttle to 128 Kbps or 64Kbps is over limit.


I think we shall stop here and tomorrow we will continue to talk to you about another MNO (Mobile Network Operator).
