Two-chip modem consumes half the power of existing HSPA+ 21 Mbps solutions

ST-Ericsson has launched a power-efficient and compact HSPA+ modem capable of transmitting data at speeds of up to 21 Mbps. With up to fifty per cent lower power consumption than competing HSPA+ 21 Mbps modems available on the market, the highly-integrated M5730 will enable engineers to produce small, affordable and power-efficient HSPA+ smartphones, USB-dongles and embedded modules.

Mobile devices equipped with the M5730 modem, which is already being sampled by customers, will be able to offer up to double the high-speed Internet browsing time of mobile devices using other HSPA+ 21Mbps modems.

According to Magnus Hansson, Senior Vice President and head of the LTE and 3G Modem Solutions division at ST-Ericsson, "We anticipate seeing smartphones and other connected devices based on our new HSPA+ modem shipping in early 2011, enabling consumers and business people to spend more time surfing the Internet at high-speeds and less time worrying about power adaptors and sockets."

ST-Ericsson's M5730 claims to be the first two-chip 21 Mbps modem and the smallest HSPA+ 21 Mbps solution to date. Using just two chips makes the M5730 very compact, reducing the bill of materials for device manufacturers. It also has exceptionally low-levels of heat dissipation enabling it to be embedded in a very wide range of devices.

The M5730 makes use of the 64-QAM advanced modulation technique, providing end-users with higher average throughput speeds and enabling mobile operators to make more efficient use of their spectrum. ST-Ericsson's field tests with mobile operators found the use of 64-QAM technology results in an average 30 percent increase in spectral efficiency.

Recently, the Global mobile Suppliers Association (the GSA) reported that 73 HSPA+ networks are currently up and running and 127 operators in 59 countries have committed to HSPA+ network deployments. Devices based on the M5730 can be rolled out quickly, as it uses the same modem protocol software as the M570 HSPA+ 21Mbps platform which has passed several major American, Asian and European mobile operator IOT tests.
