ETRI machine-learning-based frequency forecasting method set as international standard

A machine-learning-based methodology developed by South Korean researchers to assess and predict frequency availability has been adopted as a new reference approach in international radio spectrum management. The Electronics and Telecommunications Research Institute said an ITU-R Study Group 1 meeting in Geneva approved a new report on spectrum availability assessment and forecasting. The methodology draws on ETRI research using mobile network data and will be issued as an official ITU-R report after final editing.

Industry officials cite intensifying handset purchase support and marketing competition, and say unified 5G-LTE plans and added benefits in low-priced tiers are weakening MVNOs\' traditional price appeal.
