In our last post, we looked at the importance of regular independent automated mobile network audits and delved into a use case in which over $1 million worth of “hidden” equipment was discovered in an operator’s network. This post looks at a use case that is all too common in networks around the world.
Is this thing on?
“Mobile Network Operator rolls out 5000 new LTE sites in record time” – does this sound like a familiar headline? Every year, operators worldwide roll out new sites at a rapid rate. This is generally great for subscribers in terms of coverage and capacity, but sometimes subscribers read the headline and wonder why they still have to stand in the corner of their garden to successfully make a call, or why calls are always dropping on their frequently-travelled route home.
With regular network audits, operators can ensure that new sites being deployed are configured with the correct parameter values. More importantly, operators can ensure, after the new sites have been optimised, that they are indeed activated and generating revenue.
At several mobile network operators where Digitata Networks’ products were used to perform network audits, it was discovered that numerous cells in the network were in fact deactivated. A deactivated cell does not carry any traffic, which means it does not generate revenue for the operator.
Some of these deactivations are the result of rapid rollouts, but not all. A cell must be deactivated to change certain parameters. An overworked engineer could easily forget to reactivate a cell after changing the relevant parameter. Without regular automated network audits, this would only be picked up after monitoring KPIs or receiving customer complaints.
Could you be losing over $1.5 million a month due to deactivated cells?
When auditing the network of a single vendor at a Tier 1 operator, 5239 deactivated cells were detected. Of these, 3900 should have been deleted in the OSS after cutovers. 986 cells were flagged for further investigation and action. However, 353 of these cells had been deactivated in error…
Using the results of the audit, the operator was able to reactivate these cells, where required, leading to an immediate increase in voice and data traffic in those areas, which in turn resulted in an increase in revenue. This increase in revenue from the affected cells was estimated as follows:
|Voice Traffic (ERL)||Data Traffic (UL+DL) MB|
|Average traffic uptake per cell @ Busy Hour||3 ERL||50 MB|
|Average traffic uptake per cell @ Day||15 ERL||600 MB|
|USD per min/MB||$0.10||$0.05|
|USD generated per day/cell||$90||$60|
|Cells that were Activated||353|
|Revenue USD due to activation||$31,770||$21,180|
|Estimated TOTAL Additional Revenue USD||$52,950 per day|
As per the above calculations, the operator had been losing about $52,950 per day of revenue due to the 353 cells deactivated in error. That equates to approximately $1.5 million dollars a month.
