Ericsson XL QoS Project: A Smart Way to Manage Bandwidth

I am in Ericsson XL Quality of Service (QoS) project for Jabodetabek area. This project will help XL to utilized its 3G network more efficient, avoid cell congestion, thus make its service more reliable to their customers.

XL's network in Jabodetabek is powered by recent Native Ethernet technology by Ericsson ML TN. This equipment support TCP/IP over the air. VLAN, traffic queuing and classification,are supported.

What is QoS?
In simple words: any packet data in the network traffic will be classified, higher class packet data will be prioritized other than lower class. For example, signaling and voice will be treated as top priority, while email/web packet data is lower priority.

This project should finish at the end of June 2012. I hope XL could serve the customers better :).

What If Mobile Phone With Modular System

I have Nokia E63. This Old Skool has been accompanying me for about 3 years. And now these my needs: GPS and high resolution camera above 12MP. How to upgrade my Nokia E63? Its easy, buy a new brand cellular phone :).

I wonder if there is a cellular phone with modular system. I mean, I only need to replace the camera module and I get my Nokia E63 with high res 12MP. Or, I only need to replace analog audio amplifier with Yamaha one, and now my Nokia E63 has a better sound quality. Or, add GPS module easily to get GPS capabilty (GPS bluetooth plugin module is not good choice). And this is the main idea, I want upgrade my phone with lower price than buy a new one :). I think this is a good idea, imagine how many used cell phone polluted our Earth. And buyer will save their money too.

Dear reader, if you are a cellular phone engineer, please help me. I want a modular cell phone, I wish my dream come true.

Internet Mobile Broadband: Flash vs Tri

Looking for an alternative, I interested in Telkomsel Flash unlimited. View subscription price, well Rp. 100ribu for 14 days. Not be bought. I stick with Tri, even slow but not sure:).
Approximately mid-February yesterday, saw the web Telkomsel again for prime promo Flash 50ribu. It cost 50ribu for 300MB a month quota, through the quota restricted 64kbps speed. Pretty tight, because the 3G signal in the area of ??Bandar Lampung is quite extensive.

Telkomesl Flash speed statistic, bandwidth will be limited up to 64kB/s after fair usage quota

I ever use Super Tri form HCPT (Hutchison CP Telecom, a Hutchison branch in Indonesia) . Tariff is quite economical, Rp. 50k for a month with 1GB data quota (after reach limit, connection will be limited up to 64 kB/s). When I was in Lampung, sometimes received HSDPA. Pretty tight traffic in the can be. After use for a  month,  3G signal is not available anymore, just EDGE. So really slow browsing.
Actually, if Tri have 3G signal network is wide enough, I am more comfortable using Tri. Price is more economical. Options packages are quite varied and still fit a mediocre bag like me. You can surf with only Rp. 25k a month.

Overall, Telkomsel Flash is superior because it was supported better infrastructure. Telkomsel is the largest 3G/HSDPA network and with promo pricing formula for the Internet package broadband, Flash deserve a choice.

O yes, I work in the field of telecommunications, so a bit much to know "inner side" of system operator. Telkomsel I think is still a "giant" in terms of infrastructure compared to other operators.

Highly influenced by the availability of mobile Internet 3G/HSDPA, because 2G/EDGE idealy network for access from mobile phones only and is less satisfactory when used for browsing from the laptop. Mobile broadband internet market is still wide, the trend is also increasing. Friend at work has had an average GSM modem. Instead of the cafe ya mending laptop.Operator must plug the modem in improving the range and quality of 3G networks, customers would feel more at home use its mobile internet products.

Postpaid GSM Subscriber: The Forggoten One

I am kartuHALO of Telkomsel users, this is from the office facilities. In addition to also use a prepaid kartuHALO simPATI of operators, this is my number private.
Well, my appeals, which this simPATI more than kartuHALO promotional packages.

In my opinion ...
Mobile operators should encourage customers to prefer using prepaid than postpaid. Post-paid users are generally more loyal, and this advantage for the operator.
Why? Because the operator can reduce the cost of manufacture and hire simcard phone number.
I think for that phone number is not free, it only made ??free to users for the sale of "fertile".
As far as I know, there is the term "churn rate", rate of GSM number that being inactive.
This is certainly a waste for the operator because there are hidden costs to buy these numbers.
