Leveraging Existing Towers: The Smart Path to 5G Expansion
Telecom operators across Indonesia are choosing to upgrade existing tower assets rather than constructing new sites. This approach slashes capital expenditure, accelerates rollout, and maximizes the return on the tower infrastructure already owned by providers like Mitratel.
Upgrade Over New Build – What It Means for Operators
By retrofitting current masts with 5G radios, operators add new spectrum capacity without the lengthy permitting process required for fresh constructions. In Bali‑Nusra, Telkomsel upgraded roughly 220 sites in the past year, turning each tower into a multi‑band hub that supports both 4G and 5G traffic.
Technical Adjustments Required
5G equipment is heavier and draws more power than its 4G predecessor. Mitratel’s engineers have reinforced foundations on high‑traffic towers in Denpasar and Badung, while also installing solar panels to offset the increased electricity demand. A recent IEA report notes that telecom sites can consume up to 30% more power when supporting full‑band 5G.
Future Trends Shaping Tower Infrastructure in Indonesia
1. Network Densification and Small Cells
As the demand for ultra‑high‑speed broadband grows, especially in tourism hot‑spots like Bali, operators will complement macro towers with dense small‑cell deployments. GSMA research predicts that Indonesia will need an additional 15,000 small‑cell nodes by 2030 to meet 5G capacity goals.
2. Shared Tower Models and Neutral Host Platforms
Shared‑infrastructure agreements enable multiple carriers to rent space on the same mast, spreading costs and speeding up coverage. Mitratel’s portfolio already hosts tenants such as Telkomsel, XL Axiata, and Indosat Ooredoo Hutchison, positioning it as a natural “neutral host” for emerging 5G services.
3. Green Energy Integration
Beyond solar panels, the next wave will see towers equipped with battery storage and even wind turbines where feasible. This aligns with Indonesia’s national renewable energy roadmap targeting 23% renewable electricity in the telecom sector by 2025.
4. Edge Computing at the Tower Level
Embedding edge servers inside tower cabinets reduces latency for applications like AR tourism guides and real‑time traffic analytics. Early pilots in Bali have demonstrated sub‑10 ms response times for location‑based services when processing occurs at the tower rather than in distant data centers.
Real‑World Example: Bali’s Tourist‑Driven 5G Boost
During the 2023 holiday season, data traffic in Badung surged by 45 %, prompting Telkomsel to temporarily boost 5G capacity on existing masts. The upgrade not only maintained service quality for thousands of visitors but also showcased how agile tower upgrades can respond to seasonal spikes without new construction.
FAQs – Quick Answers to Common Queries
- Will 5G require a completely new network of towers?
- No. Most 5G rollout leverages existing macro towers, supplemented by small cells where higher density is needed.
- How does tower sharing reduce costs?
- By allowing multiple operators to colocate equipment on a single mast, the capital and operational expenses are split, leading to lower lease fees and faster deployment.
- Is renewable energy viable for telecom towers in Indonesia?
- Yes. Solar and hybrid solutions are already powering towers in Bali and Nusa Tenggara, cutting both OPEX and carbon footprints.
- What is edge computing and why is it important for 5G?
- Edge computing processes data close to the end‑user (e.g., at the tower), reducing latency and enabling real‑time applications such as AR, IoT, and autonomous vehicles.
Pro Tip for Telecom Professionals
When planning a 5G upgrade, conduct a structural load analysis on each tower to determine reinforcement needs before hardware installation. This proactive step prevents costly retrofits after deployment.
