# Size of a transmission packet

1. ## Size of a transmission packet

Hi all

I am designing a wireless communication system (based on Aloha like algorithm) for node discovery for vehicular communication with frequencies in the range of 2.4 GHz or 5 GHz (not decided yet).
The transmission rate is $\lambda_o$. The transmission time for discovery packet is $\tau = 1ms$(or 10 ms or 100ms).

My question is, how can I find the packet size.

What? Your question is like "I'm driving 2 hours, or maybe 5 hours, how fast am I driving?" Unless I'm missing something. And I have no idea what $\lambda_o$ or $\tau mean. MAYBE your answer is packet size= ($ \tau) * ($\lambda_o$) , i.e. data rate (data/sec)*transmission time(sec)=data.

You REALLY need to clarify your question.
