It would be better if i could understand you :/
What’s wrong with speaking english?
I thought this course would be taught mathematically like an engineering course..??
My question is on Handoff:
If user switch from base station(B1) operating at frequency(f1) to base station (B2) operating at frequency(f2) this means user earlier transmitting signal at frequency f1 is now transmitting at frequency f2 how does this not effect the communication at other side (which earlier operating at f1 and still at f1)
Now there is a wireless solution to stream video content from PC to TV.
At 7.46 is it microwave or medium wave ?

Nokia manufactures phones in India, don’t they? Maybe more mobile phone design and manufacturing should be done in India.
after seeing wireless market prediction done by Dr Rajan bose came to reality now, I do not know why Indian companies not venturing into mobile phone design and manufacturing. Why are we buying imported mobiles, rather buying mobiles “Designed by Indians”
i have a doubt mm waves attenuate so quickly versus other waves,then why we use microwave for long transmission

now we got even more !

Good lecture.
Well could you give some information regarding Underwater Wireless Communication?
Existing technology, challenges and future developments, etc.etc.
because of the skin effect. high frequency, conductors attenuate signal rapidly.
why do mm waves attenuate so quickly versus other waves?
you guys rock!!! Thank You for sharing the knowledge.
