  7. Security complexity • Need location awareness • 802.11i 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 • Companies should regard wireless security on the air-interface as a stop-gap measure until inherently secure protocols are widely available • The use of 802.1x integration to corporate authentication mechanisms should be the out-of the box default for all Wi-Fi infrastructure • Companies should adopt an “any-IP address, anytime, anywhere” (what Europeans refer to as a “Martini-model”) approach to remote and wireless connectivity. • Provision of full roaming mobility solutions that allow seamless transition between connection providers
