2. SOME DEFINITION

3. Definition
• BTS Hotels
– BTS Hotels is a unique concept that helps in providing connectivity at
locations where setting up of towers is not permitted due to various
regulatory/ security requirements.
• Fronthaul
– Fronthaul represents the need for antenna suppliers and carriers to be
able to increase the bandwidth from the cell site to the RRH (remote
radio head) dynamically from a remote location, thus reducing the
requirement for on-site manpower. This ‘smart network’ functionality
will be particularly important to carriers operating in Europe, the
Middle East and Africa, where infrastructure sharing is common –
either on the mast, or at the BTS.
– ODAS : Outdoor Distributed Antenna System
– FTTA : Fiber to the Antenna

6. ODAS : Outdoor Distributed Antenna System
• ODAS definition: A network of spatially separated
antenna nodes connected to a common source via
transport medium that provides wireless service within
a geographic area or structure.

7. ODAS
• Using macro cell sites to cover deep inside a building
with many walls and perhaps even with reflective
windows is not practical.
• The power required to do so would interfere with the
delicate frequency planning of a dense urban area.
• Additionally, to have a dedicated cell site for every
small coverage hole in a city would be cost prohibitive.
• Instead, the most common wireless network solution
today is ODAS.
• The DAS system is attached to a cell site and relays the
same signal to multiple antennas throughout a building
or region.

8. ODAS
• ODAS deployments were initially popular because
they could accurately apply coverage the hard to
reach places (large arenas, tunnels, skyscrapers)
but they have gained more popularity as a
deployment with less visual impact than a macro
site.
• Many townships push for ODAS as a solution in
place of a large macro tower inside the borders of
the town.
• ODAS nodes have been growing at a much faster
rate than regular cell sites.

10. BTS HOTEL CONCEPT

11. BTS Hotel Concept
• A BTS hotel is simply an aggregation of fixed wireless
traffic resources (BTS, Node B, iNode B) into a single
location called a hotel.
• This aggregation enables the individual BTSs to share :
– Power
– Shelter
– Security
– Heating
– Ventilating
– Air-conditioning (HVAC)
• BTS Hotel is Outdoor Distributed Antenna System

12. BTS Hotel Concepts
Main components :
• Remote Location
Node
• Hub

13. BTS Hotel Types
• A BTS hotel can be designed to accommodate:
– A single-carrier, single-technology (SCST)
configuration
– A single-carrier, multiple-technology (SCMT)
configuration
– A multiple-carrier, multiple-technology (MCMT)
configuration

17. NEED AND BENEFIT

18. Need for BTS Hotels
Insufficient Coverage
• The 3G and 4G networks generally operate at higher frequencies (above
2GHz). In traditional macro networks, there are 'shadow' areas where
signals can't reach - urban canyons where buildings block signals from the
nearest tower, the interiors of buildings where building materials block the
signals, and dense public facilities such as subways, airports, stadiums etc.
Relatively weak signals in these shadow areas, coupled with high
bandwidth required for new services, make it more important to find ways
to improve the coverage.
Shrinking Capacity
• Legacy cell is designed only to provide voice services at lower frequency
bands. It can only provide the present days data services within smaller
areas.
Expansion Difficulties
• Large BTS (base transceiver station)/cell site deployments are costly,
making the traditional network expansion process expensive. Even if the
operators are willing to invest in new macro cell sites, local regulatory
requirements make this process extremely cumbersome and practically
impossible.

19. Need for BTS Hotels
Rising OPEX
• High fuel prices and higher numbers of distributed cell sites make it
difficult for carriers to rein in the cost of maintaining their macro
BTS sites.
Poor flexibility
• It is difficult to retrofit the existing cell sites to deliver new protocols
and services, while at the same time it creates a challenge for
network planning and efficient radio utilization.
Insufficient and Expensive Backhaul Capacity
• To support higher bandwidth requirement and the launch of new
services, the carriers are required to continue adding new lines
often by leasing them from the competitors. The carriers, therefore,
must find new ways to reduce backhaul costs, which now typically
represent more than 30 per cent of the OPEX.

20. BTS Hotel Value Proposition

21. Benefits
• Increased level of physical network security and
decreased costs.
– Only a single location needs to be hardened, rather than
multiple locations.
• Decreased costs for site leases.
– A single, larger location replaces numerous single BTS
sites.
• Decreased cost for power and uninterruptible power
supply (UPS).
– A single power and UPS system can serve multiple
BTSs, whereas each typical conventional site must have its
own power and UPS system.

22. Benefits
• Decreased cost for BTS maintenance.
– All BTSs can be maintained in a single visit, rather than the
multiple visits needed to service discrete conventional
sites.
• Decreased cost for backhaul.
– Only a single, high-capacity backhaul transmission facility
from a BTS hotel to the core is required, rather than
numerous low-capacity backhaul facilities from each cell
site to the core.
• Pooled traffic resources.
– Configuring resources in this manner positions the
network for the future by making these resources readily
available for reallocation as needed.

35. BTS HOTEL MARKET

36. BTS Hotel Market : Global
• According to ABI Research :
– Growth of DAS networks is expected to expand annually at
about 25% over the next 5 years
– world market for active DAS goes from $2.5 billion in 2009 to
more than $9 billion in 2014
• Mobile Experts Predicts 29% Growth in Outdoor DAS or BTS
hotel Equipment Market
– This market has grown from practically zero in 2005 to almost
20,000 nodes today,' says Joe Madden, Principal Analyst at
Mobile Experts.
– This rapid growth comes as a result of the very quick
deployment timeline that is possible with Outdoor DAS
systems”.

37. BTS Hotel Market : Global
• In-Stat has several key take-aways for the market:
– In-Stat views DAS as an emerging technology. In-Stat believes that the
total global revenue from DAS was US$ 6.55 billion in 2010. This is
likely to more than double to US$ 13.26 billion in 2015.
– In 2010, North America is the leading DAS market. By 2014, Asia
Pacific will catch and over-take North America in terms of new DAS
revenues.
– Hospitals are the vertical market that represents the best opportunity
in DAS.
– In 2010, In-Stat estimates that 15,000 new nodes were deployed in
metro-area outdoor DAS. Globally, this number will reach 32,580 new
nodes in 2015.
– DAS deployments will not be as common in regions without significant
3G subscription penetration. By 2015, neither the Middle East & Africa
nor CALA reach $1 billion in new revenues.

38. BTS Hotel Market : Indonesia
• Big 3 operators : Rp 700 billion (2011)
– Telkomsel allocates Rp 300 billion per year for
property agents / building developers for providing in-
building coverage
– XL dan Indosat allocates about Rp 200 billion
respectively per year for property agents / building
developers for providing in-building coverage
– These costs exclude : the backhaul link leased
• Annualy 25%
– 2012 potential market will be : Rp 900 billion, excludes
backhaul link costs

39. BTS Hotel Lease Pricing
• For example, the cost of leasing an outdoor
neutral host DAS node varies between $5,000
and $12,000 a year.

40. WHY VENDOR INVOLVED?

41. Why Vendor involved?

42. Why vendor involved ?
• Right now, BS equipment costs is cheap
compare to other components of base station
expenses
– Only 40 % from CAPEX
– Or 16 % from total base station TCO
• Equipment vendors see the opportunity to
acquire other 84 % expenses per BTS
• So, vendors start to involve on managed
services by leasing ‘their network’

43. RECOMMENDATIONS

44. Recommendations
• Develop BTS hotel solution as managed service
product and combine with metro-e backhaul
business
• Implement the Neutral host of BTS hotel for
providing multioperators solution
• Sinergizing the BTS hotel solution with Public Wifi
products to obtain :
– Collocation BTS hotel equipment with Wifi Public
hotspot
– Sharing backhaul infrastructure to increase business
margin
