Network planning very low data rates and throughputs

Recommended Posts

Hello everyone,

 

I notice that, for  802.11n 5GHz air interface, max data rates in DL and UL in 64 QAM High Transmission Mode (MCS) is 62.68 KBit/sec. This value seems very low. I understand from literature that 802.11n has a max theoretical data rate of 450 Mbps. I request forum members to please guide me which settings in MCS or anywhere in network planning tool which I need to change to increase this data rate to real world values.

Please advise.

 

Thanks

Balaji

When defining a network planning project in ProMan with the attached wst files for 802.11n 20 MHz bandwidth there is a datarate of 58.5 MBit/s for the 64QAM High transmission mode. This is for a single MIMO stream according to IEEE specs (see the figure below). This means when using four MIMO streams in parallel the max. datarate is 260 MBit/s.
