Agere Systems has announced it is making breakthrough receiver technology available that significantly improves data connectivity and call quality for mobile handsets operating over HSDPA-capable 3G/W-CDMA networks. Cell phones equipped with Agere's new enhanced receiver will experience fewer dropped calls, improve transmission range in poor call conditions by as much as 25%, and provide network operators with the advantage of extended cell capacities. In addition, Agere's technology enables a reduction in cell phone bill of material costs of more than US$6 for mass market handsets in comparison to other receiver technologies.

The continued growth in mobile phone usage worldwide is challenging operators to ensure that networks are optimised for a more pleasing user experience as the world moves to higher capacity 3G networks. To combat the signal degradation that is often experienced as users travel further away from cell towers or when vast numbers of users are connected to a network, Agere has developed its receiver solutions to enable stronger performance under these strained conditions. Agere's enhanced receiver technology boosts 3G mobile handset range by up to 25% without adding to the cost and size of the phone. Agere's enhanced receiver technology provides an up to 3dB improvement in signal-to-noise ratio performance by filtering out background noise and reducing transmission power. Agere's solution employs receiver signal processing techniques that exceed the industry specification for 3GPP R5 receivers to offer performance that is nearly parallel to R6 receivers in most network conditions.

Alternatively, other solution providers are turning to receiver diversity methods or multiple receivers that sacrifice power consumption and add costly antennas and radio frequency (RF) chips for higher throughput performance in handsets. Agere's solution is an adaptive multi-path receiver that filters out background interference and reduces transmission power requirements for clearer voice calls without adding costly additional components.
