 Wide bandwidth, multiple packets
 Not susceptible to eavesdropping, 64
  bit key used for encryption and
  authentication
 Recently used with Smart Card
  technology
General Packet Radio Service
 Subscriber Identity Module Card, PINs
  provide equipment security
 Authentication and encryption
 Firewall to protect from outside
  connections
Virtual Private Network
 Data is encrypted on VPN client and
