6.5.2 Choosing a Radio Channel

Figure 2: Overview of channels operating around 2.4GHz; for ease of channel selection

Figure 2 provides an overview of the allowed channels for operating on IEEE 802.15.4, the

standard that Awinda is based on, around 2.4 GHz. The bottom row of the figure shows the

channels on the 2.4GHz, the top row shows how WiFi channels use the spectrum. This

should indicate to the user that the best channels to use when you know which channel WiFi

is on. When in an environment where WiFi is also expected to be in prevalent use, but you

are not sure which channels, try Channels 11, 15, 20 or 25.

Bluetooth uses all of the spectrum around 2.4 GHz, but will (try to) avoid channels in use by

other systems including Awinda channels.

6.5.3 Select Radio Channel for Wireless Connection

A number of wireless frequency channels are available to connect the Awinda Master with

the MTw’s. When the wireless configuration menu is open, create the wireless network by

first selecting the radio channel for communication between the Awinda Master and the

MTw’s.

To select the radio channel, double click on the value under the heading “Channel” and

select the radio channel from the drop down menu. This channel will be enabled on the

Awinda Master.

6.5.4 Turn Radio On

After selecting the radio channel for the wireless communication, click “Radio On”. The radio

transceiver of the Awinda Master will turn on and it which will search for MTw’s on this

channel.

For a wireless connection between the Awinda Master (either the Awinda Station or the

Awinda USB Dongle) and the MTw’s, the MTw’s should not be docked in the Awinda Station,

because while docked, the radio of the MTw is turned off. It is advised to remove the MTw’s

one by one instead of all at once.
