Performance

2200mW NextG USB-Yagi TurboTenna

Test result of the antenna performance at 96% of the up/down speed at source.

  • The antenna was setup pointing towards a dual band wireless router at a distance of 50 meters.
  • The wireless router was rated at 20dBm with its WAN port connected the ISP's fibre optic broadband modem.
  • The ISP provides a broadband service of 100Mbps upload and 100Mbps download.
  • There was no obstruction getting in the way.

Test result of the antenna visibility and signal strength improvement compared with the notebook internal WiFi card

  • WiFi = the netebook internal WiFi card
  • WiFi2 = the 2200mW NextG USB-Yagi TurboTenna
  • Initially WiFi scanned 12 networks with the sighal strength of 4 bars, 3 bars, ... , 1 bar to be 1, 4, 4, 3 respectively.
  • Then WiFi was switched off before WiFi2 was turned on.
  • WiFi2 scanned 15 networks with the sighal strength of 4 bars, 3 bars, ... , 1 bar to be 8, 7, 0, 0 respectively.
  • There were 15 networks in the test area with furtherest signal soruce being at 1 km away.

CnSR Extender

Test result of throughput of the CnSR

  • CnSR was the SSID of the computer running iperf3 server app developed by the BERKELEY LAB.
  • The Android phone was running the iperf3 client app also by the BERKELEY LAB.
  • CnSRi was the SSID of the CnSR Extender, which we wanted to know whether bandwidth loss was incurred when it was sitting in betweeen the WiFi data path of the CnSR server and the Android phone client.
  • As you can see in the screenshots, the bandwidth was virtually preserved by the CnSR Extender indicating a superior performance of data throughtput.
