Spirent TestCenter: What would be behavior of WIFI Transmit clients and throughput rates with multiple Ethernet receivers?
Single WIFI client sending to multiple ethernet receivers.
Rates would naturally be dependent on the negotiated phy rates.
Although there are theoretical max rates for the different wifi types, the signal may not be good enough to have negotiated to give the max phy rate.
In either case what ever is negotiated, having a single wifi client sending to multiple receivers will naturally be split among the receivers.
Let's say there are two receivers.
Client sends 1.2 Gbps max due to negotiated phy rates.
Sending to a single 1G client may give 1 Gbps received.
Sending to two 1G clients may give 600 Mbps to each.
(Note that conversion from WIFI to Ethernet will have some over head so you may not really get matching data rates between total Tx and total Rx.)
This would even be more noticeable with Active TCP sessions since there will be additional overhead for that.
