Where Liquid Radio was about supporting capacitygrowth and flexibility in the Radio Access Network (RAN),Liquid Net smartly carries the theme forward to transportand core networks promising an optimization of not only
Nokia Siemens Networks stands out among the majornetwork equipment providers for having a well-articulatedCustomer Experience Management strategy.
Over the last ear Nokia Siemens Networks has made
user traffic but CAPEX investments
significant strides in articulating its view of the intersectionpoint between policy control and adjacent areas (such as SDM,charging, and DPI, including common feature planning), a
common go-to-market strategy and generally positioning the
Base Station Vendor Matrix Company Rankings.
Nokia Siemens Networks has a leadership positionin security.
