If you haven't heard about the all-wireless enterprise, then you've missed an important networking paradigm shift. Wi-Fi networks offer secure mobility and a tremendous ROI. In the early days of Wi-Fi, significant challenges included management, security, mobility, deployment, reliability, and radio resource management. Yes, basically everything was a challenge. Those were certainly interesting times for the Wi-Fi market. Now, Wi-Fi vendors regularly tout utility-like reliability, stating that their infrastructure platforms can support mission-critical applications and be deployed and managed with minimal expertise.
That brings me to the point of this whitepaper: Wireless 2.0. First, let's define what Wireless 2.0 is. Perhaps an easy way to do that is to give you a list of characteristics of what we think Wireless 2.0 is:
- The pervasive, flexible, and self-healing primary access layer
- As deterministic as Ethernet, but with higher reliability and ROI
- As resilient and scalable as the Internet
- Secure and seamless mobility that is invisible to the user
- Integration with and leverage of the existing Ethernet infrastructure (as opposed to an overlay)
- Powerful, easy-to-use, and virtualized platform management that is available in a variety of delivery modes and cost models, including cloud-based.
To summarize Wireless 2.0 in a single statement, you could say it's, "Wi-Fi that works, so you don't have to."

This is a great paper that's both extremely informative and "fun" - an adjective that I reserve for materials that are presented in an entertaining fashion.
I really like the way that this paper digs rather deeply into both the history and the evolution of wireless nets. In particular, the various sections address key issues that must be addressed as your WLAN grows. Additionally, the issue of whether and how cloud computing fits in the wireless environment is covered.
One of the aspects that makes the paper "fun," btw, is the inclusion of a number of rhetorical questions that make for excellent food for thought.
