Currently, ALL IP is the development trend of mobile networks and mobile broadband has become the focus in the industry. Mobile content, basic networks, terminals and the like are gradually maturing. Yet, operators are facing a variety of challenges, one of which is from the transport network supporting the development of mobile services.

Mobile operators are banking on broadband services for continued revenue growth. Mobile broadband services in turn generate substantially more traffic than voice service and SMS. Since mobile backhaul is a major component of mobile OPEX, controlling its cost is the key to turning mobile broadband revenue into profit. Operators and wholesale backhaul providers are employing several network strategies for doing this, using an array of copper, fiber, and microwave technologies.

You can choose from various PTN technologies, including PBB-TE, IP/MPLS, and T-MPLS. Which one is the most effective for mobile backhaul?

Microwave communications systems transport a large amount of mobile services and are as important as optical communications systems for accessing services through base stations. Mobile operators throughout the world have diversified base station access resources. In Asia-Pacific, base stations are allocated relatively rich optical fiber resources. In Europe where costs are high in manpower and optical fiber laying, and in other areas with special environmental conditions, microwave-based systems are still major transport media.

The rapid development of mobile services has increased pressure on mobile backhaul bandwidth, especially in terms of 3G service provision. Abis optimization can to some extent ameliorate this situation by enhancing transport efficiency, but how great is the value generated?

Microwave communication describes a traditional transmission technology that benefits from an inherently robust lifecycle. Known for its rapid deployment capability, low cost and flexible application potential, it has been widely deployed in a range of communication contexts spanning fixed, mobile and private networks. The global scale of 3G/WiMAX construction has delivered with it the latest application scenario for microwave communication, the specific features of which have evolved in alignment with technological development and shifting market pattern

Mobile broadband triggers transport network transformation Mobile TV, mobile video ads, mobile search… In past decades, the potentiality of these functions never occurred even to the grandees who could afford a cell phone. They would neither have imagined that a cellphone could be so light and smart, nor could they picture themselves enjoying a range of amazing functions other than making phone calls on the move. Today, not only are mobile phones commonplace, but users are increasingly familiar with web surfing, cyber payments and online gaming through cell phones. On a global scale, mobile operators are striving to popularize mobile broadband services, the ARPU contributions from which are steadily rising. In Europe, for instance, the income derived from broadband mobile services forms over 20% of total revenue, while it exceeds 30% in Japan and Korea.
