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.

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.
