7 Security complexity Need location awareness i if corporate wireless link VPN if not corporate Still not perfect security, insecure connections needed to set up café/home connections Security on direct connections too

10 Challenges to the industry 1. Companies should regard wireless security on the air- interface as a stop-gap measure until inherently secure protocols are widely available 2. The use of 802.1x integration to corporate authentication mechanisms should be the out-of the box default for all Wi- Fi infrastructure 3. Companies should adopt an any-IP address, anytime, anywhere (what Europeans refer to as a Martini-model) approach to remote and wireless connectivity. 4. Provision of full roaming mobility solutions that allow seamless transition between connection providers
