Telecom is an ever evolving field where new protocols/technologies are researched, introduced, and updated after regular intervals based on technological advances, market situations, and field/conformance test experiences. Working in telecom protocol field for ~10 years, I came across number of standards in the field of SS7, VoIP, GSM, GPRS, EDGE, UMTS, and WiMAX. Though grasped basic concepts of these standards, I always felt the need of putting down important points/learnings to be able to recall (and so to retain) the knowledge gained.

This blog is a step in that direction. The articles contain my own understanding of standards - coming out of project experience, reading of various books on the subjects and standards themselves.

I have tried to emphasise on "why" as much as possible. But I know it is difficult to answer each why and also difficult to come out with reasoning behind each protocol procedure, message, and parameter. What I have tried is to note down as many important points as possible in terms of diagrams, message charts, and descriptions. As always, time is limited; some of the images may not be really good , some of the articles may not be adequate or perfect. So I urge the reader to use the content only after verifying it against standards and/or consulting it with experts in the field. Having said that, I update the articles as I go along.

In addition to telecom, I have also put articles on other topics that readers may find useful.
