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
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.
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.
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.
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
BTS Hotel ConceptsMain components :• Remote Location Node• Hub
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
Need for BTS HotelsInsufficient Coverage• The 3G and 4G networks generally operate at higher frequencies (above 2GHz). In traditional macro networks, there are shadow areas where signals cant 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.
Need for BTS HotelsRising 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.
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.
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.
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 $9 billion in 2014• Mobile Experts Predicts 29% Growth in Outdoor DAS or BTS hotel Equipment Market – This market has grown from practically zero in 2005 to almost 20,000 nodes today, says Joe Madden, Principal Analyst at Mobile Experts. – This rapid growth comes as a result of the very quick deployment timeline that is possible with Outdoor DAS systems”.
BTS Hotel Market : Global• In-Stat has several key take-aways for the market: – In-Stat views DAS as an emerging technology. In-Stat believes that the total global revenue from DAS was US$ 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.
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
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.
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’
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
