Wireless has evolved fairly dramatically over the past 12 years. Initially customer deployments were characterized as best effort and casual. Deployments tended to be confined to conference rooms or small office environments. The products required to enable this type of coverage could be seen as first generation – operating very much in a hotspot mode. As enterprises looked to move into more pervasive wireless deployments, the need to manage the network centrally became increasingly apparent. The introduction of the controller-based architecture allowed IT to manage the wireless network as a system and made it easier to cover the entire enterprise with a wireless signal. From here, the introduction of n allowed the wireless network to respond to the demand for more capacity being driven by media-rich applications n provided the throughput that many leading adopters of wireless were looking for. Yet, while n solved the capacity problem, many companies still struggled with how to make the network more reliable and easier to operate. The need to deliver a truly mission-critical wireless network has evolved network features to deliver systems that have the intelligence to be self-healing and self optimizing. Essentially, organizations want to know that the investment they make in n is going to be worth it. New network intelligence is providing performance protection for n networks.

9. Why is the market transitioning to WiFi
Why is the market transitioning to WiFi? Increased demand and improved customer experience
Over 80% of all mobile internet and video usage in the US takes place in a fixed location
Many smartphone applications are nomadic, not mobile, allowing WiFi to provide the necessary access
Almost half of all smartphone and tablet device traffic is already connected via WiFi
US households are moving aggressively towards broadband untethering; by 2015 nearly a quarter of broadband households will purchase a mobile/cellular element
The number of WiFi connected portable devices will double between 2010 and 2015
Technology improvements are delivering a more cellular-like experience, which will accelerate WiFi use
By 2014 US public WiFi hotspot usage will have grown 200%

“The use of small cells, including femtocells and carrier Wi-Fi solutions, directly reduces the need for busy hour capacity in the macro network, and as a result they directly reduce the carrier’s CapEx and OpEx requirements for that network.”

11. Why is the Market Transitioning to WiFi
The Smartphone and Tablet revolution continues
The number of WiFi connected portable devices will double between 2010 and 2015 to more than 2 billion devices worldwide
Almost half of all smartphone and tablet device traffic is already connected via WiFi
Compelling video and social networking apps are clogging mobile networks
Global mobile data traffic will increase 26x from 2010 to 2015
Users expectations have morphed from nice to have  must have, anywhere, anytime
Many smartphone applications are nomadic, not mobile, allowing WiFi to provide the necessary access
By 2014 US public WiFi hotspot usage will have grown 200%
Technology improvements are delivering a more cellular-like experience, which will accelerate WiFi use
