How get more data rate : Change the number of bits, the bandwidth or the packet duration

Question

I found definition say that, the rate of packet is define by

R=N/BD [b/Hz/s]

where N is the number of bits , B is the bandwidth and D is the packet duration. So suppose that R'=N/BD.

If I would like that my data rate of packet is equal to R''=2R', which variable can I change to get R''? is it N,B or D.

Answer 1

If you want to double the packet rate you could change any of the things it depends on

• Halve the packet size, or
• Double the bit rate, or
• Halve the packet time

Or change two things appropriately, or all three.
