Ask A Question


Questions related to Satellite Communications and Networking for Internet, Broadcasting and other Satellite Applications as well as Space Segment qualification procedures , regulatory as well as commercial, can be answered. Questions or clarifications on Cellular Mobiles as well as Wireless Networking can also be answered, as I have taken up Teaching the Graduate Students in Engineering College! Software questions in these areas may not be in my flavor.

What do you like about this subject?

I love Satellite Communications and Applications. As a career Engineer, designed many a netwrok and as Consultant, planned and implemented Satellite Applications.

What do you still hope to achieve/learn in this field?

Make satellite communications retain their charm and utility in face of tough competetion from competing technologies. Also to make it clear to all that Technology is not complicated but is very, very simple: if only explained with good understanding!!!

Something interesting about this subject that others may not know:

Just believe in this field for Communications and Networking for all times to come!!

Something controversial or provocative about this subject

Present days feeling that Satellite Communications is going to be obselete vis-a-vis other newer Technologies is a wrong one. Such a sophisticated Technology like Satellite Communications and Networking is unachievable thru other means because almost all latest ones are point-to-point systems. Geographical independence is the forte of Satcom.
