Can MNOs deploy 5G using existing spectrum?

Question

Accepted Answer

MNOs May Be Permitted to Deploy 5G on Existing Spectrum

Mobile network operators (MNOs) may be granted permission to deploy 5G technology utilizing their current spectrum holdings through a method known as dynamic spectrum sharing (DSS). This approach allows for the simultaneous operation of both long-term evolution (LTE) and 5G services within the same frequency band. The DSS technology dynamically adjusts resource allocation in real-time based on the prevailing demand for either 5G or LTE.
Dynamic Spectrum Sharing Capabilities

Dynamic spectrum sharing (DSS) is a technology that enables the coexistence of LTE and 5G within a single frequency band. It is designed to intelligently manage spectrum resources by assessing the real-time demand for both technologies. This dynamic allocation ensures that spectrum is utilized efficiently based on immediate network needs.
Impact on 5G Coverage and Speed

While the implementation of DSS is not expected to deliver significantly faster speeds compared to current 4G networks, its primary benefit lies in its capacity to rapidly expand 5G coverage. This capability allows for a quicker widespread adoption of 5G services across broader geographical areas. Furthermore, DSS offers the potential for future carrier aggregation with newly available sub-6GHz spectrum, enhancing overall network capacity.
Government Review of 5G Rollout Strategy

The Malaysian government is currently undertaking a review of the existing 5G Single Wholesale Network (SWN) rollout strategy. A final decision on the future direction is anticipated by the end of March. Communications and Digital Minister Fahmi Fadzil has engaged in discussions with various telecommunications companies, reaffirming the national objective to expedite 5G coverage to 80 per cent by the close of 2023, a revision from the initial target of end-2024.
Potential Dual Wholesale Network Model

An alternative scenario under consideration involves transitioning to a 5G dual wholesale network (DWN) model, which would permit the use of 5G DSS. This model presents greater complexity, as it would necessitate a reallocation of 5G spectrum to both the established wholesale network and a potential second network. This second network could be established by MNOs that have not yet acquired stakes in the current wholesale entity, such as Maxis and U Mobile.
