In a live TD-LTE 4G network trial with a commercial operator and a spectrum-owning local agency, Nokia Solutions and Networks (NSN) demonstrated that authorized shared access (ASA) is a technology that paves the way for future 5G networks.
With dynamic access to underutilized spectrum frequencies, operators will be able to harvest extra capacity to offer unmatched coverage and customer experience for mobile broadband users.
Increasing subscriber demand for faster networks requires an innovative approach to spectrum sharing and reducing network congestion. Earlier this year, the NSN and CORE+ consortium took a giant leap forward with the worlds’ first spectrum sharing trial of ASA on a live 2.3GHz TD-LTE network.
The ASA concept allows mobile operators’ networks to share frequency bands from other types of incumbent systems, such as government agencies or TV broadcast networks, while guaranteeing quality of service for both. Increasing spectrum is one of the core pillars of NSN’s Technology Vision 2020, and the company has again demonstrated it has the technology and expertise to drive the vision forward.
“The benefit of ASA is that it provides both the technology and regulatory framework for sharing spectrum,” said Marc Rouanne, executive vice president, Mobile Broadband at NSN. “Our trial showed that operators can get up to 18% extra bandwidth for mobile broadband networks cost effectively. This technology works with existing LTE and TD-LTE networks and does not require specific software for the end-user devices, making it easy to deploy and transfer the benefit directly to the mobile customers.”
For the live trial, NSN deployed its network elements in three Finnish cities: commercial Single RAN Flexi MultiRadio 10 base stations in Ylivieska, commercial core network in Oulu and commercial NetAct network management system in Tampere.
