ST-Ericsson has developed a two-chip modem that it claims offers mobile internet speeds of up to 21Mbit/s, while requiring only half the power of traditional modem technologies and improving network efficiency for mobile operators.
The M5730 modem runs an HSPA+ connection to be used in network equipment and end-user devices that the firm claims marks a breakthrough in mobile computing and could benefit smartphones, USB dongles and embedded modules in PCs.
"The M5730 reduces power consumption by 50 per cent while improving the delivery of data for applications such as video or gaming to mobile devices," said the head of ST-Ericsson's LTE and 3G modem solutions division, Magnus Hansson.
"This technology has been available for some time but previously was only really used in embedded connections due to its power consumption levels, but we have managed to halve that and I don't think any other company will come close to that."
Hanson explained that by using a 64-quadrature amplitude modulation (QAM) advanced modulation technique, the M5730 could not only provide higher speeds but also improve the efficiency of spectrum.
"As the technology is based on industry standards other firms will integrate it in their systems over time to improve network efficiency and there is a lot of pressure on mobile manufacturers from mobile operators to do this," he said.
The company said that it had carried out field tests with mobile operators of the modem, and the 64-QAM technology had provided an average 30 per cent increase in spectrum efficiency.
Overall, Hansson said he expects the technology to form a reasonable step in the evolution of HSPA+ and would generate revenue for the company for some two or three years, especially with the rise of connected devices.
"We expect to see this technology go into high-end smartphones at first before working down into mid and lower tier devices as well as being used in new connected devices such as gaming consoles or cameras," he added.
