Ekahau Opportunity - WLAN

Due to rapidly falling prices and shrinking form factor, 802.11 chipsets will find their way to a vast number of different type of mobile devices!

"If any one technology has emerged in the past few years that will be explosive in its impact, it's 802.11" - Bill Gates

Intel believes that 90% of mobile PCs will have wireless functionality by 2004 – integrating 802.11 chipset in its new Banias processor platform.

Motorola & others release plans in 2003 to embed Wi-Fi in cell phones.
