AWTG recommends an upgrade path for an incumbent 2G/3G operator’s mobile wireless network based on keeping an overlay macro layer capable of delivering broadband data speeds matching the 2G current level of coverage by a combination of HSPA+ and 3G rollout, with the support of UMTS900. Later, LTE networks and core network evolutions are suggested to maximise the ability of the operator to deliver new services on the fixed and mobile network in a consistent, transparent and efficient way.
