DO Advanced - Enhanced Performance When and Where it Matters

EV-DO is a widely deployed mobile broadband technology. There are about 240 million subscribers as of Q1 2012 and that is projected to exceed 300 million subscribers by the end of 2013 . EV-DO Advanced is an evolution that provides higher network capacity and improved user experience under various deployment topologies. Operators can deploy EV-DO Advanced through cost-effective software upgrade, thus maximizing return on their investment.


Details

The increasing popularity of data services is stressing many wireless networks. Much of the growing data demand originates from smartphones, or always-on devices, which connect to the network frequently even without any action by the user. EV-DO Advanced optimizes allocation and use of resources in existing wireless data networks by taking into account uneven loading in networks, leverages increasing penetration of always-on devices and improves user data rate, especially for those at cell edge.

EV-DO Advanced consists of 3 major features: Smart Networks, Enhanced Connection Management and Device Enhancements. Smart Networks adapt network resources and deliver required performance to high demand areas when needed. Enhanced Connection Management utilize network resources more efficiently so that more always-on devices can be supported in the network. Device enhancements can improve cell-edge user data rates without any dependence on infrastructure upgrade or standard changes.
Most features in EV-DO Advanced can be supported by existing EV-DO standard with the rest supported by EV-DO Revision C, published by 3GPP2 in June 2010. Some Enhanced Connection Management techniques have been deployed in existing EV-DO networks. Qualcomm Corporate Research & Development demonstrated Smart Networks techniques in 2010. Smart Networks was first launched by KDDI in April 2012.

As smartphones gain popularity, users are paying more attention to their battery life. Qualcomm developed a number of features, such as data-driven receive diversity, Discontinuous Transmission (DTX), Quick Paging Channel (QPCH) and Multi-AT Page, which reduce battery consumption when a DO device is in active or idle state.

Operators are often concerned with the capital expenditure as they increase the capacity of their networks. Qualcomm is therefore developing a reference design for a next-generation channel card based on CSM6850 chipset. It enables the use of state-of-the-art multi-core CPUs and multi-core DSPs and provide approximately 30% BOM reduction for infrastructure vendors and 30% lower power consumption.
