To ensure the coexistence of 5G and 4G Devices, enabling the use of the new 5G Core Network, operators need to manage a transition period in which both 5G deployment architectures are present.

Taking a devices perspective, this white paper looks specifically at how Mobile Network Operators (MNOs) who currently operate 4G and 5G Non Standalone (NSA) networks can evolve to support 5G Standalone (SA) networks.

This paper presents a way to handle and optimize this transition. The goal is not only to guarantee an effective usage of the most valuable FDD and TDD Sub-6 bands (< 6GHz) but also effective usage of all frequency assets.

The re-farming strategies that can be implemented by Operators will inevitably be influenced by the speed of penetration of 5G Devices and the frequency bands that they support. Accordingly, a potential migration timeline has been defined.

This White Paper addresses the performance criteria of base station antennas, by making recommendations on standards for electrical and mechanical parameters, by providing guidance on measurement and calculation practices in performance validation and production, and by recommending methods for electronic data exchange. It also addresses recommendations on applying existing environmental and reliability standards to base station antennas.
Highlights in version 12 are updates on wind load measurement and alignment with the NGMN BASTA Active Antennas White Paper.
