Hello,
Today I got the result of the throughput test of rtl8723bs(the WiFi module of LeMaker Guitar).
The Test Environment:
  • Boards: LeMaker Guitar Coar Board v1.3 & LeMakerGuitar Base Board Rev.B
  • Router: TP-Link(300M): TP-WR842N
  • Test Location: The underground garage (There is no other WiFi wireless signal)
  • PC: DELL E550(Ubuntu15.04 in vmware workstation)
  • Tool: iperf

The Test Method:1. Connect the PC and the router through a ethemetcable, and let LeMaker Guitar connect to the router’s wireless network
2. Test the transmit speed:
Run the next cmd on PC:
  1. iperf -s
Copy the Code
Run the next cmd on LeMaker Guitar:
  1. iperf -c <PC's IP> -i 4 -t 360
Copy the Code
3. Test the receive speed:
Run the next cmd on LeMaker Guitar:
  1. iperf -s
Copy the Code
Run the next cmd on PC:
  1. iperf -c <LeMaker Guitar's IP> -i 4 -t 360
Copy the Code
Testing Result:

Hi,
According to my reading about: RTL8723BS it has one (1) antenna and supports maxium 150Mbps.
150 / 8 = 18.75MB/s  so I guess your table above needs some corrections.

PS: nice idea with the underground Garage

The RTL8723BS with 150Mb/s  is just the maximum physical rate of theoretical transmission with single stream in 802.11n draft.

Nice result for a miniPC WiFi. It would be more powerful If you guys implemented AP6330/AP6335 in guita. It is 2.4G+5G wifi module and bluetooth 4.0.

I see. So Ferrari's are faster than Volkswagen. What about the price?  Post time Oct 23, 2015 07:40

If the WiFi module support the 5G(802.11a, 802.11na), it will have a higher cost. Besides, not every one needs it. If you want to use the board to connect to the HostAP with 5G, and i think you can try to use the USB WIFI adapter (Eg: RT5572).
We have tested the USB wifi adapter which use the RT5572 Chip on the Guitar, and it can work well.

Thank you for the Tip. I ruled out the cost. It is a nice board for 25 bucks.

The result looks impressive, on par with TI WL18xx with mimo.

One more questions: Does rtl8723bs linux driver support wifi-direct?
