Moldova’s national telecommunications operator Moldtelecom has completed a joint network optimisation project with intelligent operations provider Kenmei focused on improving 4G LTE performance and initial optimisation of Moldtelecom's 5G NSA C-band network.

The two companies have worked together previously on an optimisation engagement. This new project covered LTE multi-band and carrier aggregation performance, mobility and load balancing, the interaction between the 4G and 5G layers, initial VoLTE tuning, and the identification of the cells holding performance back.

Using Moldtelecom's network data, Kenmei could analyse configuration and performance to find where the network was not yet delivering what its spectrum allows. Recommendations were reviewed with Moldtelecom's engineering team before implementation, then measured against network data afterwards to confirm what each change had produced.

The project identified and corrected individual cells that were underperforming on handovers (the moment a call or data session passes from one site to the next). The weakest improved from 14% to 91% success, and handover success between sites and frequencies now holds at a stable 99.9%.

Analysis of downlink throughput showed how much capacity the radio network can deliver beyond what is used by current service plans, giving Moldtelecom quantified input for its prepaid and postpaid service strategy. The project also provides the operator with a measurement baseline for the continued rollout and growing use of its 5G network.

Victor Moldovanu, Head of Mobile Network Development at Moldtelecom, said: “Our engineers and the Kenmei team worked as one team throughout the project, and a lot of technical knowledge moved between them along the way. That knowledge stays with us as we keep developing and optimizing our 4G and 5G networks.”

Javier Grau Cavanillas, COO at Kenmei, added: “Our part was to read what its data was saying and turn that into changes their engineers could weigh, apply and verify themselves. Working that way is what makes an optimisation hold after the project ends.”
