2G is still the most common deployed mobile access technology. It is hard to believe but as per my discussions with probably more than twenty Mobile Operators, 2G , especially GSM is the most common mobile access technology.
4 Main, Key Design Principles of Mobile Networks – I will explain the 4 key design principles of cellular networks in plain English. Read more
There are many broadband services Service Providers offer to their customers today. As a network engineer you need to know the most common services and their advantages, disadvantages, design characteristics and so on.
In this post, I will introduce these services and if I can see interest from the readers, I will explain the design aspects and deployment models of each one of them.
So if you are reading this post right now and interested to know more, put your comments in the comment box below.
Note : I am going to explain broadband services in this post, not baseband, we are in 2017 right !
Access network infrastructure link the backbone network to the customers.
There are two groups of broadband access technologies. Fixed broadband technologies and Mobile Broadband technologies.
You can find many Mobile Broadband articles on the website.

You are invited to attend the one hour Technical Webinar “Introduction to Mobile Broadband Technologies”.
The essential Mobile Broadband Concepts and principles are illustrated with the below Agenda Read more
For me and for most of Mobile broadband professionals, we are used to meeting the Telco Vendors such as Ericsson, Huawei, Cisco, Nokia, etc. It was a mind-shift for me personally when I started to meet RedHat, Mirantis, & Vmware as a part of the NFV talks and I was really surprised that a company like RedHat is a member of the European Telecommunications Standards Institute (ETSI) with more focus on the Mobile Broadband Evolution participating in Mobile Edge Computing (MEC) Work Group.
It is obvious nowadays that the borders between different technology domains are fading in the sense that Networks are shifting into software-defined Networks with new abstraction layers realizing network convergence.
With this post being the last one, I chose to talk a little bit about some trending and future Mobile Broadband technologies with the goal of having an overview of the Technology Roadmap.
NFV (Network Functions Virtualization)
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
Most of the educational documents related to PS Core Network start with Call Flows. Attach Call Flow, PDP Context, Paging, etc. Basically that was my problem when I started working in PS Core because the Call Flows include a lot of messages which in turn include a lot of parameters and Information Elements so starting with the Call Flows without knowing at least the Identifiers included in these messages is not the best approach to understand PS Core principles.
This is why this article will be all about the MBB terms that are commonly presented in all Call flows and in most of the MBB talks in general. Once one is comfortable with that, the Call flows will be easy to interpret.
I am bringing some for clarification.
Core Network Architecture in 3G Mobile Networks – Most of the Mobile Broadband Networks worldwide are currently delivering Data Services based on 3G & 4G Technologies. Although 4G/LTE is widely deployed globally but still there are countries and operators running 2G/3G with relatively convenient Data rates to the market demands.
In this article, I am focusing on the Packet Switched Network Architecture in 3G, the corresponding interfaces, & the relevant protocols relying on the terms and principles explained in the first article.
The Basic Core Network Architecture in 3G mobile network is shown in the below figure :
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“!
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.
