Motorola has implemented numerous security management practices and capabilities in the operations and architecture of its network. Figure 1 shows an overview of the layered security approach typically deployed in Mobility Enabled Access (MEA) networks that utilize the Quadrature Division Multiple Access (QDMA™) Radio protocol.

Implemented Security Features

• Quadrature Division Multiple Access (QDMA™) air interface based on state-of-the-art military technology.
• All MEA transceivers are hardware authenticated and registered with the network to minimize insertion of unauthorized devices.
• All 802.11 station card  transceivers are software authenticated by a AAA server to minimize use of cloned or stolen devices .
• All MEA transceivers are software authenticated through the use of MEAP, a Motorola proprietary authentication  scheme.  
• Motorola’ architecture minimizes the impact of RF jamming, denial-of-service, and physical attacks to the network.
• End-to-end IP-based infrastructure supports VPN and other standards-based encryption schemes.
• Ad hoc architecture keeps data secure when hopping through intermediate terminals.  
• Group authentication and personal firewalls protect MEA subscriber devices from peer-to-peer attacks.

As a result of this layered approach to wireless security, MEA-based networks typically offer the following benefits:

• Motorola solutions meet federal and local government standards for data privacy.
• MEA based networks are resilient to interference, attacks, and failures.
• Motorola’ s technology is flexible, and can incorporate new security approaches for the future.
