This HetNet module covers deployments and trends forecasts by Caroline Gabriel. Forecasts were based on a combination of data from:

• Detailed surveys, interviews and operator-by-operator modeling of the IMG-40 groups.
• Studies of the deployments and strategies of the top 100 4G operators, as tracked by Rethink Technology Research’s quarterly surveys, interviews and desk research. 
• Deeper interviews with senior executives at 25 tier one operators about their detailed plans for RAN deployments to 2021.
• Input from ecosystem vendors on shipments, technology strategies and competitive landscape, also updated quarterly.

Based on the surveys of operators and vendors, it was then calculated how those cell sites would be equipped – by base station type, technology, frequency band etc, leading to a detailed unit and market size measurement.

All modules contain between 6 and 15 data tables plus regional breakdown, with accompanying commentary consisting of graphs and concise commentary on the assumptions underlying the forecasts, and the key factors driving them.
