3)
Wireless throughputs vary with the environment of the test setup –
distance, obstacles, type of obstacles, etc.
4)
The throughputs are also dependent on whether all the Wi-Fi
components in the test support 40MHz and 20MHz or only 20MHz
bandwidths.
To check Transmit throughputs, first run the command below on the 2
nd
PC/Laptop:
# iperf –s <-u> -i 1
This command starts an iperf Server which is listening for data. It prints
the received throughput at an interval of 1 second. The <-u> in the
above command is for UDP traffic. If it is not mentioned, then the traffic
is TCP.
Next, run the command below on the PC/Laptop connected to the EVB.
# iperf –c <IP address of 2
nd
PC> <-u> -i 1 –b 100m –t 120
This command starts an iperf Client which starts transmitting data to the
Server.
To check Receive throughputs, run the Server command first on the
PC/Laptop connected to the EVB, followed by the client command on the
2
nd
PC/Laptop.

OneBox-Mobile in Wi-Fi + Bluetooth Classic Coexistence
Mode
This section describes the installation of WiFi and BT Classic modes. Note
that to use the Coexistence mode, each protocol should be loaded
individually one after the other.
1)
Open the common_insert.sh file present in “/home/OneBox-
Mobile/<interface>” using the gvim editor.
2)
Ensure that the DRIVER_MODE and COEX_MODE as set as below
a.
DRIVER_MODE = 1
b.
COEX_MODE = 2
NOTE: For SDIO mode, ensure that the SDIO stack related modules are
already inserted in the kernel. Follow the steps below for this:
# cd /home/OneBox-Mobile/SDIO
# sh load_stack.sh
# lsmod
Verify that the output of the “lsmod” command lists the sdhci.ko,
sdhci_pci.ko, mmc_block.ko and mmc_core.ko modules. This is a one-
time process and need not be repeated unless the modules are explicitly
removed by the user.
3)
, to install the Wi-Fi Client
mode.
