Mobile Broadband

Mobile broadband refers to any wireless technology that enables high-speed Internet access in a public environment, via laptop, PDA, smartphone or other device. Today, mobile broadband technologies include Wi-Fi (used at hotspots and in most municipal networks), WiMAX (in its early stages), and 3G (used by many cell phones and some PCs for Internet access). Regardless of the specific technologies being deployed, consumers and enterprise customers now expect faster and more convenient Internet access, no matter when and where they want to connect.
