A technical background in wireless packet data telecommunications is required for this course. Additionally basic knowledge of voice roaming in CDMA networks is recommended.

Security in wireless networks is a concern for both operators and users.  Fraudulent network usage can result in loss of revenue to operators and unexpected charges and inconvenience to users.  When roaming is involved, these costs can increase significantly. CDMA networks support various security mechanisms to protect operators and users against such costs.  Among the most important of such mechanisms is authentication.  In this course, students learn why authentication is important and how it works in CDMA voice and packet data networks. While the course discusses various authentication mechanisms that apply to both roaming and non-roaming scenarios, it focuses on roaming scenarios to show how visited and home networks work together to enable authentication.

After completion of this course, the student will be able to:

• Explain how authentication works in voice and data roaming environments
