Spectrum Refarming

Step 1:
Defining a Problem
Bandwidth issue for new RAT

  • Do you think about new RAT deployment on your existing 2G spectrum to maximise its profitability?
  • Do you think about the most cost effective way to accommodate increasing traffic demand?
  • Are you concerned about possible 2G QoE degradation associated with Spectrum Refarming?

Step 2:
Challenges
Maintain the best QoE to the end users

  • 30-50% of the voice traffic is carried on 2G layer, therefore 2G is still treated with high importance
  • The critical part of spectrum refarming lies in 2G quality of experience retention. Why? Because 2G traffic has to be carried with less spectrum
  • Optimisation of 2G frequency allocation minimises collisions therefore provides better service quality to the end subscribers

Step 3:
Solution
Spectrum refarming with DATAX

  • Trouble free co-existence of different radio access technologies on the same „radio highway”
  • Maximum profitablity from operator’s radio assets
  • Delivery of the best possible QoE on 2G technology layer

Issues with RAT introduction

The biggest concern of operators is degradation of 2G service caused by dependency of quality on traffic load, resulting from capacity vs. quality trade-off principle. When taking some of the 2G spectrum off to be used for new technology, the 2G traffic density in the spectrum is higher as the spectrum gets smaller.

Spectrum Refarming is still the most cost efficient way to introduce new radio access technology, i.e. LTE or UMTS 900MHz. And one needs to remember that still 40-60% of the voice traffic is carried on 2G layer, therefore still 2G should be treated with high importance by mobile operators.

How does DATAX solve these issues?

DATAX has the know-how and experience to take the biggest concerns away. Combination of advanced methodology to calculate traffic load per 2G spectrum unit together with DATAX toolset equipped with the best-of-breed art allocation algorithms will increase capacity and maintain QoS at the same time.

We will also take care about network parametrisation related to intra- and inter-technology traffic management in a manner consistent with Operator’s strategy and available system features.  Necessary amount of traffic will be migrated to appropriate layer, avoiding congestion and blocking.
