Closed-loop SON is an attribute that the majority of mobile operators desire from a SON solution today. But is their expectation of closed-loop SON the same as what vendors truly offer, or is it missing a critical aspect?

The Mirage

A Closed-loop SON system would have the ability to automatically receive parameter network sets, run optimisations and then provision parameter set adjustments back onto the network – automatically and faultlessly. This loop part of a C-SON integration with vendor OSS, is the basic foundation of any C-SON solution ensuring the automation of coordinated SON activities.

But does this truly define what Closed-loop SON is?

In Reality

The true meaning of closed-loop SON is actually much broader. It isn’t just the configured connections that allow for the closed-loop data transfers, but rather a wider network-centric approach, which continuously seeks for anomalies in network performance. Closed-loop SON can only be completed when realising corrective C-SON techniques, which consider the current level of network performance degradation, while comparing normal traffic pattern behaviors.


Don’t let subscribers down because of LTE FallBack

LTE growth continues apace. Currently, there are over 300 LTE networks with around 250m subscribers globally. And it keeps increasing. As part of their deployment strategy, many mobile operators have adopted an LTE overlay approach. This involves deploying LTE on top of existing 2G and 3G networks. Overlay is regarded as the one of the fastest and arguably, the most cost effective approach to roll out LTE. There is no need to decommission an old network and replace it with a new network, with an overlay there’s only one network to operate, manage and monitor.


Interview: Technology consultant, Oi Brazil: “Oi considers small cells as important tools for improving customer experience by increasing coverage and capacity.”

Oi Brasil is the brand name of Telemar, one of the four large carriers operating in Brazil, with over 50 million subscribers as of December 2013, according to Informa’s WCIS statistics. LTE deployment and uptake is in its early stages, but Alberto Boaventura, technology consultant for Oi, describes how delivering capacity rather than speed is the focus for its network deployment.

Boaventura is speaking at the fifth annual LTE LATAM conference, taking place on the 28th-30th April 2014, at the Windsor Barra Hotel, Rio de Janeiro, Brazil, where you can catch him speaking on Day Two describing a case study focusing on how 4G is providing a new level of experience for customers.

How big an opportunity is the forthcoming World Cup for Oi Brasil?

Oi is as official sponsor of the 2014 World Cup in Brazil and our focus is to accomplish this important mission.

How important will LTE roaming be in time for the World Cup next year?

Currently, the infrastructure and interconnection agreements are on course to provide LTE Roaming in 2014.


Interview: VP Americas, Small Cell Forum: “The benefits of small cells is the ease of deployment”.

Andy Germano, VP Americas, Small Cell Forum is taking part in a panel discussion: “Small Cells and SON” in the Hetnets track on Day One of the LTE North America conference, taking place on the 21st-22nd November 2013, in Dallas, Texas, USA. Ahead of the show we speak to him about the latest in small cells and how he they will be deployed.

What do you think are the biggest challenges in dealing with the implementation of small cells into a network?

As small cells migrate into HetNets and open access to outdoor applications, frequency coordination with macro cellular networks becomes more important.  Another area of importance is backhaul.   One of the benefits of small cells is the ease of deployment. Selecting the right backhaul connection including scalability for future growth potential is also important.


Sizing up SON – Self-Organising Networks revealed

This post is by Avijit Ghosh, assistant vice president of technology, Aricent 

The ‘Self-organizing Networks’ (SON) concept is a ‘hot’ topic for today’s wireless networks, especially with the expected proliferation of small cells and heterogeneous networks.

The idea is that the network should, while minimising cost and staying within constraints that may be applicable, automatically and continually adjust itself to maximise its own key performance indicators: generally coverage, capacity & quality of experience.

It is also expected that such a system should generate information, analysis and visualisation to assist effective forward planning of the service provider’s business.
