Telecom Italia to double peak data with HSUPA

Telecom Italia has found it can double its network’s peak data rate, and vastly increase network capacity using High Speed Uplink Packet Access (HSUPA) technology from infrastructure vendor NSN.

The operator tested NSN’s solution in a lab environment in the northern Italian city of Turin, and found that it could achieve uplink speeds of up to 11Mbps.

According to a major difference between HSUPA and HSDPA is that there is only one transmitter per cell for HSDPA while for HSUPA, there might be many transmitters.

NSN’s said that its HSUPA solution with 16QAM modulation uses its Flexi Multiradio Base Station and increases the uplink speed to enable mobile subscribers to upload photos and videos to social media and cloud services more quickly. Devices supporting HSUPA 16QAM are already available on the market.

The vendor added that its advanced Interference Cancellation receivers are already implemented in Telecom Italia’s network and they reduce interference caused by high bit rate users, thus raising uplink throughput by up to 50 per cent and extending a mobile device’s battery life.

“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.”
