HSPA+ modem halves power use

ST-Ericsson HSPA modem NV + has a two-chip it says is capable of transmitting data at 21Mbit / s, and "fifty percent lower power consumption than the competition HSPA + modems s 21Mbit / available on the market.
But the company is not the amount of energy consumed by the M5730 chipset, or is compared under what circumstances or modems that the M5730 was, or what method was used for comparison information. The company did not disclose the process technology of the chips are applied, or the chips can be produced. Also gave no information about the HSPA + functions distributed between the two chips.
The company said the M5730 uses 64 QAM modulation and supports 3GPP Release 7, GSM / EDGE in four groups and WCDMA / HSPA + in five groups. The chipset supports 5.76Mbit / s upstream.
After the global mobile Suppliers Association (GSA) 73 HSPA + networks are already with 127 operators and 59 countries have pledged to HSPA + network installations.
ST-Ericsson said it is sampling the M5730 to customers, and should appear in smart phones, USB flash drives and modules.
