Throughput VS RSSI

Question

When I conducted tests using P300, the results showed below.
RSSI is high yet Throughput is low
RSSI is low(not high) yet Throughput is high

I sometimes got these results.
In my understanding, RSSI relates to Throughput.

Why does this happen? What is the relationship between RSSI and Throughput?

Thank you

Hi Kat,There are several methods to send data from AP to client in 802.11 standard,such asDSSS and OFDMthe data throughput also depend on the SNR level, AP calculate the RSSI and SNR to select a modulation method to send data RSSI is high yet Throughput is lowthere could be high RSSI but if there are low SNR the AP will select less complex modulation method that could effect the through put.RSSI is low(not high) yet Throughput is highThere could be high SNR, so may the AP select the bit high complex modulation resulting high throughput.For more details please feel free to drop a mail.Thanks and regards,Harekrishna MondalEmail- harekrishnamondal99@gmail.com
