New 3G features really can make your whole day so much better

Let’s take a look at some of our latest enhancements to 3G technology, used by around two billion people worldwide, which can make your entire day a lot more interesting.

We are launching some new software features as part of the Nokia Liquid Radio WCDMA Software Suite that will boost the efficiency of 3G networks and enable operators to better utilize their existing 3G resources.

To understand how it can impact the user experience, let’s imagine a day in the life of a typical subscriber, let’s call her Rose, and see what difference each of these new features makes to her mobile experience and mobile operator.

Dedicated Priority

We begin the day at work in the office. Rose uses her mobile throughout the morning to check road traffic updates and various other mobile broadband services, enjoying the fast services.

The Dedicated Priority feature means that the operator can set subscriber group specific priorities for 2G/3G/4G and frequency selection as required. More than that, operators can upgrade their existing user experience camping strategy with the effective priority process, covering both home and roaming users.

The feature also allows a user to camp or be prevented from camping on LTE, based on his or her subscription.

Interference Control in HetNets

It’s lunchtime and Rose leaves the office for an hour to go to a nearby shopping mall.

The Interference Control in HetNet feature minimizes the interference between small cells with low power base stations and large cells with high power base stations using the same carrier frequency in the same geographical area. This maximizes the combined capacity of all the cells.

So as Rose enters the shopping center, the excellent service quality she gets outside from the macro base stations is preserved as her smartphone moves into the small cell coverage area. And the great experience is maintained as she moves throughout the mall, which, being lunchtime, is packed with shoppers. Rose quickly snaps a few shots of sale items to share on WhatsApp with her friends. If the feature was not activated, interference would degrade the small cell capacity and with so many people accessing the network, throughput would fall off. So the operator is able to keep Rose happy even in the busiest indoor locations.

Enhanced Mass Event Handler and UL CoMP

It’s the end of the working day and Rose is looking forward to meeting up with her friends at this evening’s football match.

The new Enhanced Mass Event Handler feature automatically controls the traffic load in highly loaded networks. The technology tracks the rise in traffic load and cell performance as more and more users enter the stadium. It then predicts when the load will become excessive and triggers actions to control the situation.

The operator has also deployed another new feature, UL CoMP (Uplink Coordinated MultiPoint), which enables a base station to rapidly combine signals from different sectors to improve the uplink at the cell edge.

So despite the crowds, Rose and her friends can continue to make calls and upload videos and action photos of the game to their social media accounts. Rose’s operator is happy too as it is able to provide a good service at a high profile event, enhancing its brand image.

A great day

Together, all Nokia’s new 3G enhancements provide operators with the means to utilize their existing 3G infrastructure more efficiently to keep their customers happy – wherever they are and whatever they are doing.

And as Rose would surely testify – that all adds up to a great day from beginning to end. With the amazing experience that she enjoys on her smartphone 24/7, the thought of switching to any other operator never crosses her mind.

We love a happy ending!
