Main issues to be addressed
Broadband backbone Inter province backbone in Sumatra-Java-Kalimantan-Bali-South
Sulawesi exists East Indonesia is missing (Palapa Ring East) Extension to many Kabupaten still to be implemented
Mobile/wireless Broadband 3G deployed on part of the network in 2100/1900 MHz band, focused
on cities WiMAX auctioned Requires cost-effective mobile broadband everywhere
Fixed Broadband Monopoly on copper infrastructure ADSL (up to 1 Mb/s, Speedy, PT
Telkom) Monopoly on cable TV network Very limited Fiber To The Home Requires large scale fiber optic deployment
Backbone investments required
Palapa Ring East: $ 186 million Completing Palapa Ring East with Sorong-Manokwari-
Biak-Jayapura and Sorong-Fak-Fak- Timika-Merauke. Estimated at $ 145 million
Extension to remaining Kabupaten Sumatra-Kalimantan- South Sulawesi, 9.820 km, $ 113 million of which $ 31 million is expected to be not feasible commercially
Extension to Kabupaten in Eastern Indonesia. If possible $ 225 million. However most non-coastal Kabupaten in Papua lack any infrastructure to lay fiber optic cable along (no roads, pipelines, etc.). Some intermediate use of microwave might be required.
Total: $ 444 million + (part of) $ 225 million Kabupaten
extensions in Eastern Indonesia
Mobile/Wireless broadband access investments required Passive infrastructure (towers and facilities) already
established Upgrade of active radio network required (3G
everywhere, future upgrade to LTE) Backhaul from towers to backbone On the largest network about 5.000 out of 32.000
basestations are 3G. Current 3G spectrum is not cost effective for rural roll-out (would require many more towers). However if 850/900 MHz is used a simple overlay can be deployed. Estimated costs: $ 500 – 1000 million
Backhaul is crucial. Could cost around the same amount as the active infrastructure
Note: Short-term, activate EDGE feature everywhere instead of only GPRS
CAPEX/OPEX impact

Fixed broadband access investments required
Future requirement is 100 Mb/s+, many countries are deploying FTTH (like Singapore, Australia, etc.)
Main investment (50-80%) is passive infrastructure The largest investment in the future telecom
infrastructure will be in the migration to fiber optic access networks
Assuming $ 800/home then the replacement of current copper network (8 million lines) would be in the order of magnitude of $ 6400 million. Connecting up to 40 million homes would increase this to $ 32000 million
Smart and opportunistic deployment required to reduce investment level
Note: Short-term, deploy ADSL on all copper networks,increase speed to technology limit (20 Mb/s) wherepossible
Analysis
The mobile (broadband) market is highly competitive. Operators have made, and continue to make, multi-billion $ investments each year
The number of mobile operators/networks is quite high and consolidation should be anticipated. Fewer mobile networks & more MVNO’s are a likely scenario.
Use of lower frequency bands (850/900 MHz) is critical for cost-effective mobile broadband everywhere
Fixed broadband (ADSL) over copper wires, has been more or less a monopoly business although cable Internet is a competitor. Investments have been limited
A more competitive fixed broadband market is required. This implies a transition from “monopoly” on copper to “competition” on fiber.

Central Government role
Timely issuance of permits and rights of way Facilitate coordination between entities responsible
for different infrastructures for example ensuring that construction of new roads, railways, power lines and pipelines provides for co-location of fibre-optic cables. Such practice is widespread around the world for new infrastructure development
Financial incentives like a minimum subsidy for a backbone extension to a marginal Kabupaten in return for Open Access and early deployment (ICT fund)
Demand aggregation
Regulatory measures required (1)
Infrastructure sharing. For towers this has already been done. This should be
extended to include other passive infrastructure like ducts, poles, dark fibers, etc.
Open access requirements: Passive infrastructure for essential and not easily replicated
infrastructure Active layer/service layer. IP level is open and net neutrality
should be maintained The transition from “monopoly” on copper to
“competition” on fiber implies that a fully “unified” license is provided: Licensed operators can deliver all services (local, SLJJ, SLI,
Mobile, Internet, IPTV, etc.), typically over the broadband access. Current legacy regulation focused on individual services should be phased out
This is a prerequisite for a competitive fixed broadband market.
Regulatory measures required (2)
Equal access to buildings Remove all monopoly practices related to access to the
building and the in-building cable system. Allow non-Telco entities (construction companies, real
estate developers, local Government) to construct and provide passive infrastructure. However mandate open access
Number portability (mobile & fixed) for consumer protection and additional competition
Mobile/wireless broadband Allow in-band migration to 3G/4G technologies Release more spectrum for the long-term (700 MHz, 2500
MHz). 700 MHz requires an accelerated migration from analogue to
digital TV to free-up the Digital Dividend 2500 MHz is currently mostly used for satellite TV
Regional/local Government role What can be done to accelerate deployment? Timely issuance of permits and rights of way Provide and prepare passive infrastructure whenever
constructing other infrastructure like roads. Example:
Kabupaten without extension to the backbone and without
fiber infrastructure Invest in the passive infrastructure to lower the barrier
for entry. Stand-alone or as co-investor. Aggregate initial demand (schools, puskesmas,
Government offices) and tender this demand in return for early service and deployment of open access backbone and local fiber optic network
Public Works role
By default Public works should incorporate the need for ducts whenever constructing roads, etc.
Arrange a general agreement between Telco’s and the Government with respect to the use of passive infrastructure.
PLN role
PLN is operating a very large passive infrastructure of power lines and electricity access network on poles.
Fair and equal access to this passive infrastructure is important to deploy cost-effectively.
Arrange a general agreement between Telco’s and PLN with respect to the use of this passive infrastructure.
Conclusions (1)
The future of telecom is Broadband (10+ Mb/s today and 100+ Mb/s tomorrow). Fixed broadband is essential to provide real high capacity
cost-effectively Mobile broadband can be deployed fast to provide initial
connectivity Main backbone (West+ East) and extension to all
Kabupaten in West Indonesia + South Sulawesi requires a remaining investment of $ 444 million. Remaining (in particular non-coastal) Kabupaten in East
Indonesia Eastern Indonesia might require intermediate solutions like microwave
Transition from “monopoly” on copper to “competition” on fiber through regulatory steps: Fully “Unified License” for all services and phase out of legacy
service by service regulation. Infratructure sharing Open access
Conclusions (2)
Mobile broadband in the lower frequency bands (850/900 MHz) is critical for cost-effective rural deployment
Short-term fixes based on existing infrastructure: Deploy ADSL at all local PSTN switches. Where there is copper
there should be ADSL Activate the EDGE feature on the GSM network everywhere to
provide, almost instantly, better mobile internet all over Indonesia
Use demand aggregation and investments in passive infrastructure to accelerate fiber optic roll-out of backbone and access.
Consider use of the USO/ICT fund for those areas which are commercially not feasible.
Local/regional Governments can play an important role to realise broadband in their area. However it is important that the Central Government arranges the regulatory prerequisites to create a “competitive” fixed broadband market.

Why are lower frequency bands so important?
850 and 900 MHz bands offer a much better coverage than 2100 MHz
Many countries do have very extensive rural areas which could benefit from 3G (mobile as well as in “fixed” deployment) to deliver telephony and broadband service
Typically spectrum use in rural areas is less intensive making it easier to allow in-band migration to 3G at much lower cost
Examples:� Telstra Next G network (850 MHz). Covers > 2.000.000 km2
� Elisa Finland/Estonia (900 MHz)� Vodafone New Zealand (900 MHz), Australia under
construction� Optus in Australia (900 MHz)� AIS Thailand (900 MHz)� Europe is anticipated to accept UMTS 900 widely, many
trials/plans on-going
No of UMTS basestations required

A lower frequency band results in a much more cost efficient roll-out in rural areas. UMTS 900 is already standardised.
