Getting the most out of LTE networks is all about understanding the
contribution of every component, and ensuring that they work together in a
synchronized and consistent way to optimize performance.
A case in point is the Automatic Neighbor Relations (ANR) feature – which for
many operators is the first step in the implementation of SON solutions.
Managing neighbor cell relations to ensure optimal traffic handling for user
devices is one of the most labor-intensive activities mobile operators must
undertake, and the introduction of LTE multiplies the effort needed.
By automatically setting up necessary neighbor relationships based on actual
network conditions, ANR prevents failed hand-overs caused by -missing’
neighbors. It continuously secures and improves network performance, and
reduces the need for manual planning and establishment of neighbor relations.
Ericsson’s ability to drive developments both in the radio network and in the
LTE device ecosystem has been instrumental in ensuring the availability and
success of ANR in live 4G networks. ANR has been shown to deliver a 90 percent
reduction in overall network planning effort, by eliminating initial planning
and optimization, along with 100 percent hand-over success thanks to accurate
and timely addition of neighboring cells.
What does this ability to address the entire ecosystem mean in the real world
of actual LTE user experience? Independent analysts are providing some of the
answers. In its September 2011 report, -Mother of all Network Benchmark Tests’,
Signals Research Group found that in one major US city, Ericsson’s LTE network
was found to outperform another vendor’s significantly in both downlink and
uplink throughput performance. Extensive drive tests showed that the
Ericsson-delivered LTE network offered more than 20 percent faster median
download rates and three times faster median upload rates than the
competitor’s.
So when it comes to delivering an enhanced mobile broadband user experience, it
seems overall LTE performance really is more than the sum of its parts.
