HSPA+ modem halves power use

But the company did not state how much power the M5730 chipset consumes, nor did it report under what circumstances or which modems it has compared the M5730 against, or what method was used for the comparison. The company did not disclose the process technology the chips are implemented in, or where the chips are made. It also did not give any information about how the HSPA+ functions are distributed across the two chips.

The company did say that the M5730 uses 64-QAM modulation and supports 3GPP Release 7, GSM/EDGE across four bands and WCDMA/HSPA+ across five bands. The chipset supports 5.76Mbit/s in the uplink direction.

According to the Global mobile Suppliers Association (the GSA) 73 HSPA+ networks are already being run by 127 operators, and 59 countries have committed to HSPA+ network deployments.

ST-Ericsson said it is sampling the M5730 to customers and expects it to appear in smart phones, USB dongles and modules.
