AUSTIN, TX--(Marketwire - Jan 24, 2012) - As the demands of the end users have increased, with more bandwidth needed in specific locations, mobile operators have started to deploy an increasing number of small cells and a wider variety of base stations. As more LTE cells are deployed, so the mobile operators will also deploy Self-Organizing Network (SON) solutions, as defined by Releases 8, 9, 10 and 11 of the 3GPP.

SON is at the core of launching new cost-effective 4G devices and applications via a new evolutionary network concept. SONs greatly simplify legacy standard operational tasks via automated triggers for self-configuration, self-optimization, and self-management functions. The legacy centralized approach to network management is soon to be replaced by a hybrid configuration (partially centralized and/or partly decentralized) option that will enhance robustness, scalability, and integration integrity with 2G, 3G, and 4G network elements across multiple carrier networks, as the transition to 4G begins to evolve in 2012.

iGR's latest research study, Impact of Self Optimizing Networks on U.S. LTE Infrastructure, 2011 - 2016, provides a fundamental understanding of SONs, the current state of the Service Architecture Evolution that provide the transition alternatives to 4G and the potential financial benefits of SON.

"SON is an important set of concepts that will radically change the way 4G mobile networks are design, built and operated," said Iain Gillott, president and founder of iGR. "As the industry moves toward small cell architectures, with vastly more cells deployed in a given area, the industry must adopt new network management techniques to control capital and operational expenses. If SON is not successfully utilized, increased operational costs could slow the deployment of small cells."

SON is expected to significantly reduce CapEx and OpEx via automation of operational and network management costs associated with deployment, installation, operations, maintenance, training and support. SON automated functions will reduce costs associated with daily operations, including power utilization costs. Most importantly, the customer experience will be greatly enhanced as a result of greatly improved network stability and integrity.

iGR expects that LTE CapEx savings resulting from full SON implementation between 2011 and 2016 will be $2.34 billion and LTE OpEx will be $4.5 billion.
