Showing a diagram of network coverage varying in urban hubs and suburban and rural areas (pictured), a spokesman said: "LTE complements existing 3G networks. Our solution is multimode - not a 4G only or 3G only chipset." Devices will automatically switch from one coverage area to another, he added.
Asked why Qualcomm is now concentrating its efforts on LTE - rather than rival long range connectivity tech WiMax - Salvatori said: "We do not believe WiMax is going to deliver performance you cannot achieve on LTE," adding it "will be difficult to compete with the ecosystem of the 3GPP world".
However he added Qualcomm is not closing the book on WiMax - and will be "open to whatever the market will ask".
