Data rate (Therotical vs Actual)

Hi,

This is a general question , Theortically 802.11n offer upto 450 or 600 Mbps ,Why the actual data rate  is  below this rate ?

How the  value  600 or 450 Mbps theorotically calculated ? 

When we Say 600 ,does it mean RX is 300 and TXis 300 ?

What would be the actual value approximately ?

Thanks

Re: Data rate (Therotical vs Actual)

Hi!

 

 

There´s a difference between Data rate and Throughput (or TCP throughput or Goodput) It all depends on what you want to measure.

 

To answer your question in short, if your "Data rate" to the accesspoint is 600Mbps you can expect the actual throughput to be approximately half of that. Asuming the rest of the network can handle that speed of course. The reason for this is that there´s a lot of data going back and forth to make the wireless protocol work which will all be overhead on the data you wish to send over the network.

 

Please let me know if you need any more details :)
