Anytime you use "over-the-air" transmission, your data is subject to capture and thus should be encrypted if you are concerned about the confidentiality of that data. The Cisco router you refer to, in conjunction with the supported wireless interfaces, can support encryption. You will need to refer to the "radio privacy" set of commands for this router in order to enable and configure this feature. Please consult with a Cisco expert for correct setup.
