In peak conditions, the chipset can not only download at up to 7.2Mbps but upload much more quickly than older HSDPA hardware -- up to 2.9Mbps, Infineon claims.
Such improved upstream speed is often regarded as necessary for more advanced two-way Internet features on cellphones, including video calling and sending photos or videos directly to the web. Infineon also notes that the general application processing of the new chipset supports image processing for up to a 5-megapixel camera and the ability to encode or decode VGA (640x480) video in real time.
The chipset is also much more efficient than past models, the company says. The XMM 6180 platform reduces the number of chips needed from three to two and halves the number of components needed; this not only shrinks the size of the hardware by 40 percent but reduces the power draw. Power use in standby mode drops by as much as 30 percent, giving any phone using the technology more useful lifetime thanks to more of a charge kept between calls.
