SON speeds up small and macro cell roll-out in LTE

With the challenging LTE rollout schedules and cost pressure, service providers are looking for ways to increase efficiency, streamline processes, and speed up time-to-market. It comes down to the survival of the fittest. Who has the most efficient and smart network deployment tools, will be the first one to cross the finish line.

Self-Organizing Networks (SON) in mobile backhaul can help service providers to lower OpEx and shorten network and service rollouts from days to minutes. With automated SON tools, the service provider can eliminate human errors and extra site visits, and enable efficient resource utilization.

SON is ready to rise in mobile backhaul networks

According to Infonetics, the primary reasons to deploy SON (self-organizing networks) are OpEx reduction, improvement in capacity, quality, network performance, and small cell usage. I have been hearing exactly the same message in my discussions with service providers all over the world. The fundamental goal of SON is to minimize the network lifecycle-related cost.


Layered mobile backhaul architecture supports network scalability and easy management

Mobile backhaul architecture should be designed according to the needs of the carried services. One way to do this is for operators to look to the traffic volume distribution among the cell sites. Feedback that we’ve received from operators suggests that, typically, well over 50% of traffic volumes originate from cell sites in urban regions.


Smart tools enable cost-efficient small cell rollouts

Last month, I had the honor to present at the Small Cells Global Congress event in Berlin. I discussed whether public small cell backhaul solutions should be an evolution to the existing network architecture—or a revolution.

The predictions on small cells vary slightly, but the majority of analysts agree that growth will start in 2013 and rapidly continue that trend moving forward. Analysts expect that costs will settle at approximately 20% of the macro cell site total cost of ownership.
