Design goals for wireless LANs

• global, seamless operation
• low power for battery use
• no special permissions or licenses needed to use the LAN
• robust transmission technology
• simplified spontaneous cooperation at meetings
• easy to use for everyone, simple management
• protection of investment in wired networks
• security (no one should be able to read my data), privacy (no one should be able to collect user profiles), safety (low radiation)
• transparency concerning applications and higher layer protocols, but also location awareness if necessary
