Nokia Solutions and Networks has, together with Telecom Italia, recently proven the benefits of HSUPA 16QAM (High Speed Uplink Packet Access) technology. Telecom Italia tested NSN’s new solution in its lab environment in the northern Italian city of Turin, achieving uplink data speeds of up to 11 Mbps. In combination with unique NSN advanced receivers, the solution can double the peak data rate and significantly increase the network capacity.
NSN’s HSUPA solution with 16QAM modulation considerably increases the speed in the uplink, enabling mobile users to upload photos and videos to social media and cloud services more quickly. An important part of this 3GPP- compliant solution is the NSN compact and award-winning Flexi Multiradio Base Station. The devices supporting HSUPA 16QAM are already available on the market.
NSN’s advanced Interference Cancellation receivers are already implemented in Telecom Italia’s network. They reduce interferences caused by high bit rate users, raising uplink throughput by up to 50% and extending the device’s battery life. The Frequency Domain Equalizer achieves an average of 10% to 20% gain in uplink throughput, and when combined with the HSUPA 16QAM solution, increase the peak uplink rate two-fold.
“We successfully tested NSN’s HSUPA 16QAM solution and achieved uplink transmission rates of up to 11 Mbps,” said Sandro Dionisi, director of Telecom Italia’s Lab. “The results prove that this technology is effective in increasing uplink data speeds which results in a superior smartphone experience for our broadband customers, especially when they post materials and updates online.”
“As people use smartphones and social networking more and more, operators need to find new ways to raise capacity of their network uplink in order to deal with the increased traffic volumes and still offer the best mobile broadband service,” said Massimo Mazzocchini, head of CBT Telecom Italia Group at NSN. “We are excited to demonstrate our HSUPA capabilities together with Telecom Italia to help boost network performance and data transmission.”
