NSN makes breakthrough with Authorised Shared Access

Nokia Solutions and Networks (NSN) claims that a live TD-LTE network trial has demonstrated Authorised Shared Access (ASA) can offer operators extra capacity, through access to under-utilised spectrum frequencies.

The trial – which included a commercial operator and a spectrum-owning local agency – was said to show that operators can get up to 18% extra bandwidth for mobile broadband networks.

NSN went as far as to claim that ASA technology could pave the way for future 5G networks.

The move builds on a breakthrough earlier this year, which saw an NSN and CORE+ consortium claim to deliver the worlds’ first spectrum-sharing trial of ASA on a live 2.3GHz TD-LTE network.

“The benefit of ASA is that it provides both the technology and regulatory framework for sharing spectrum,” said Marc Rouanne, EVP of mobile broadband at NSN.

“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.”

The concept of ASA could eventually see mobile operators share frequency bands from other types of incumbent systems, such as government agencies or TV broadcast networks. The live trial took place in three Finnish cities.
