Mobile Backhaul Solution › Mobile backhaul is the process of connecting cell sites to core networks and data centers that host content accessed by mobile users. It requires extensive fiber deployment to support LTE speeds of 100+ Mbps. › BIT offers a fiber backhaul solution for faster deployment with a lease scheme. Their fiber core supports 1-100 Gbps for hub sites. Fiber capacity supports 100-1000 Mbps for last mile connections. › A cost analysis found leasing fiber backhaul reduces total cost of ownership by 46% compared to building fiber and 93% compared to using microwave backhaul. Leasing fiber is more cost effective than building or using microwave.

1. Mobile Backhaul Solution
› Mobile Backhaul (MBH) is the process of connecting cell site air interfaces to core networks, which are subsequently connected to data
centers that host the content and applications accessed by mobile users—both human and machine.
› New perspective on backhaul costs:
› Speed-up backhaul fiberization
› Pressure on CAPEX reduction
› Shifting the investment risk to Opex
› Better TCO
› LTE’s power-full air-interface, i.e., 100+ Mbps will require extensive backhaul fiber deployment (source: ITU’s IMT-Advanced
requirements)
› BIT offers the Fiber Backhaul solution with faster deployment time with lease scheme:
› Fiber Core - suites for HubSite to cater capacity 1 – 100 Gbps
› Fiber Capacity – suites for Lastmile with capacity 100 – 1,000 mbps

2. TCO Assumption for a µ-Wave backhaul for cap. 1Gbps:
› CAPEX for µ-Wave: ~ IDR 200 millions
› Estimate Annual O&M: ~15% of CAPEX
› Power Electricity: ~ IDR 2,5 millions /month
› Annual ISR Radio License ~ IDR 88 millions/year
Cons:
› Microwave has limited capacity
› No CAPEX required, with small setup fee
› FO core lease: 1 MIDR /month
› Unlimited Capacity
FO CAPEX for 1,000 m (based on best practice):
› Fiber core 1km : IDR 11,4 millions
› Supply/service/install: IDR 80K/m (Aerial), IDR 95K/m
(Subduct)
› Annual O&M Cost: 15% of CAPEX: IDR 13,8 Mn
› Leased Core: IDR 2 millions /month
