The real payoff comes later by layering in 700 MHz once SA is deployed to provide the wide-area coverage and uplink strength that mountainous, low-density terrain demands. - [5G Deployment Strategy for Telecom Operators: NSA vs SA](https://www.sunilkarna.com/blog/5g-deployment-strategy-for-telecom-operators-nsa-vs-sa) (19 Sept 2026): How an operator running 2G/3G/4G today should think through the NSA-vs-SA decision, multi-vendor interworking and 4G/5G vendor alignment. - [Why 5G's Spectral Efficiency Beats 4G: A Technical Deep Dive](https://www.sunilkarna.com/blog/why-5gs-spectral-efficiency-beats-4g-a-technical-deep-dive) (13 Sept 2026): Let's uncover why 5G delivers significantly more speed and capacity than 4G, even with similar bandwidth. This technical deep dive explains how Massive MIMO, beamforming, advanced modulation, and smarter network design dramatically improve spectral efficiency. ## Facts - Full name: Sunil Kumar Karna - Also written: Sunil Kr Karna - Current role: Deputy Manager, Nepal Telecom, Wireless Service Directorate, Babarmahal, Kathmandu - Experience: 27+ years in telecommunications and IT, from December 1999 - Registration: Nepal Engineering Council registered Class “A” Electronics Engineer, No. 76 - Education: M.Sc.
