In the modern era, wireless and mobile communications and the applications of information technology are increasingly preferred by both ordinary consumers and businesses.

Their utilization offers users significant mobility comfort while simultaneously providing access to almost any service available in wired network domains.

This book presents the theoretical foundation and develops the security technologies and specific vulnerabilities of four categories of wireless and mobile communication networks:

• personal wireless communication networks that adhere to the Bluetooth specifications (IEEE 802.15.1).
• local wireless communication networks that follow the IEEE 802.11 standard (Wi-Fi).
• metropolitan wireless communication networks that comply with the IEEE 802.16 standard (WiMax).
• UMTS networks, standardized by the 3GPP organization.
