Evolved Packet Core – Welcome to Long Term Evolution!

As an end user, I am always welcoming the “4G” Signal indicator on my mobile because basically for me this maps to a better Download Speed, good quality VoIP calls (skype, Hangout, Whatsapp, etc) , better Streaming, and HD Videos.

This article is all about the “4G” indicator. I am discussing the Evolved Packet Core together with the EUTRAN, Evolved Universal Terrestrial Radio Access Network Technologies that are realizing the 4G Service offered to end users.

 

 

With Data rates above 100 Mbps and latency of milliseconds that enables the best video streaming and online gaming experience; One may think of 4G networks as a replacement for 2G/3G Network which is valid in some cases. However, we see that the decision to “dismantle” 2G/3G is still in the operators roadmaps.

Before we go through the  LTE/EPC Network Setup, Let’s list three main definitions and abbreviations that are closely related to 4G. Read more

Mobile Broadband Ecosystem

Mobile Broadband… You might have heard this term before, possibly in an ISP environment. The term has always represented a name of a department within a mobile operator or a vendor organization. It is always there in profile description for telecom professionals. It is everywhere actually when it comes to a certain ecosystem or framework that delivers Internet Service using Mobile Network.

Let me bring the Wikipedia definition followed with a small note …

Mobile broadband is the marketing term for wireless Internet access through a portable modem, mobile phone, USB wireless modem, tablet or other mobile devices.

Definition is true but the note here is that you can’t rely solely on google to understand the MBB related technologies (EDGE, UMTS, 4G/LTE, etc.) because what is in google is mainly the marketing articles and the vendor specific publications which is fine but as a lesson learned, one need always to understand the technology concept decoupled from vendors influence.

The good thing is that the whole knowledge, principles, & Service descriptions for Mobile Broadband is there in the standards. Mainly the 3GPP which is freely accessible. So I’d clearly say that the “debate” that it is hard to get the knowledge of the MBB is “debatable“!

3GPP_TM_RD

One just need to know how to get the information? Which 3GPP standard Specifications? Which 3GPP Release? Throughout this article, I am going to talk about the Mobile broadband evolution and the related standardization specifications which will enable the audience to see the big picture of the MBB and the plan is that by the end of the Five articles series, readers will be on the Mobile Broadband Track.
