WIFI Technology Training

Duration: 2 days

Introduction

Driven by the use of unlicensed spectrum, WiFi has become a pervasive technology used in both business and home environments. With average selling prices of access points dropping along with WiFi enabled laptops and other devices, WiFi technology will continue to be a dominant technology in both information technology as well as telecommunications networks.
