Managed services for Sudan's transmission network could provide operational expenditure (OPEX) savings through various approaches. Backbone optimization using high-capacity transmission technologies could reduce OPEX by up to 70% associated with 2G/3G backhaul. Bandwidth optimization techniques like silent call suppression and voice compression could save up to 50% of network bandwidth. Infrastructure sharing between operators through site rental, antenna sharing, and backhaul sharing could also lower costs while improving service quality.
