The Challenge
In the process of rolling out 4G service, a Tier 1 Mobile
Operator needed to study situations where 4G
devices were being served by the existing 3G network
layer. They also sought guidance regarding the
priorities for future site deployment to maximise ROI,
so they turned to ariesoGEO to provide detailed
intelligence on the performance of the new 4G service
and the location of 4G‐on‐3G hotspots within their
network.
4G and 3G Interractions
4G‐capable devices are generally also capable of
utilising 3G and even 2G network services. The
intention is that such devices should use the 4G layer
as far as possible, deferring to lower specification
layers only when the higher layer cannot sustain the
service required. Whilst on lower layers, devices
should endeavour to return to the 4G layer as soon as
conditions permit. ariesoGEO was used to generate
maps showing the density of usage that 4G devices
were making of the 3G layer. The representation in
Figure 1 was achieved by tracking 3G activity and
filtering to include usage only from 4G‐capable
devices. In this figure, dots identify the operators’
sites, while sector symbols identify those with
operational 4G. It is clear that some 4G‐on‐3G usage
occurs in areas where the operator has yet to roll out
4G service as expected, but also in other less obvious
areas.
There are three reasons why devices may pass from
4G down to other technologies:
1. Where users request services such as voice
that are not offered by the 4G network
2. Where devices that have roamed from
elsewhere cannot access the 4G network
3. Where 4G services are unavailable or 4G
connectivity cannot be sustained
The first two reasons are considered normal, and so
are removed from the maps through additional
filtering by service type and by device capability.
Figure 2 shows only the data usage that could be
handled by a 4G network.
