Choosing Nepal’s 5G Spectrum: Balancing Coverage, Capacity, Cost and Device Compatibility
Nepal's 5G rollout hinges on getting spectrum sequencing right: launching NSA on 3500 MHz (anchored on existing 1800/800 MHz LTE) delivers the fastest, most device-compatible speed boost, while 2600 MHz serves as a proven fallback if 3500 MHz proves too costly. 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.
