Nokia Siemens Networks confirmed that it has participated in the upgrade of portions of T-Mobile USA's 4G (HSPA+) network.
"T-Mobile's 4G network is now faster than ever before and continues to deliver a faster, more reliable broadband experience in more places than any other carrier," said Neville Ray, chief technology officer, T-Mobile USA. "Nokia Siemens Networks' Single RAN has helped us to enhance our existing network through a software upgrade with minimal impact to the existing network hardware."
NSN noted that it has been working with the carrier for more than a year to drive the standardization of Long Term HSPA Evolution – the evolution of HSPA in 3GPP beyond Release 10.
The high-speed HSPA+ 42 Mbps delivered in the T-Mobile USA network is made using a more efficient 64QAM modulation rate and two 5 MHz ‘carriers' simultaneously for one data connection, based on a technically advanced Dual Cell HSDPA solution. The Dual Cell HSDPA solution runs on the existing Flexi Multiradio Base Station with a simple software upgrade with minimal impact on existing network hardware.
