Many estimates about future conditions and traffic and other forecasts can also be considered to be ‘soft’ starting points, as they can only represent a view (a consensus view or an expert view) about the future.

10.2.1 Hard Starting Points

For a new MBH network or for a MBH extension, the most obvious starting points are the mobile operator's existing networks (existing mobile, MBH and other transport networks) which are usually well known and documented. Also the present mobile customer base (type of customers and their present network usage) and present measured traffic in the existing network(s) are important starting points.

But also the other operators' networks in the same area (especially their MBH and other transport networks) may have a significant influence on what kinds of MBH solutions are feasible. These other networks are usually significant from a competition point of view – they are competitors' starting points for their network expansions – but often they can also mean good opportunities ...
