What is IBS/DAS ?

1.In-building Solution (IBS) / Distributed Antenna System (DAS)

2.Small Cell Coverage within building premises

3.Signal is restricted inside the building

4.Antenna installed inside the building

5.Low Transmit Power of Antenna

6.Smaller Antenna size

Page 4: IBS Training Module

ADAADA CellwCellwoorksrks

What drives the need for IBS ?

1. Demand of Continuous coverage

2. Indoor Activities generating high traffic

3. Poor indoor coverage of outdoor sites

4. Offloading outdoor cells with high utilization

5. Improvement of Network Performance.

STEPS IN IBS SURVEY1. Study the building architecture, with the help of floor plans & guidance from Building authorities2. Understand the requirements need in terms of Coverage, Capacity, future Subscriber growth etc.3. Identify the duct for the cable routing & component location.4. Survey on each floor using net monitor and floor plan.5. Mark the present signal level and the antenna location to be installed in the floor plan.6. Note down all the present serving cell information like CELL ID, BCCH, Rx. Level, etc.7. Identify the BTS location, antenna locations and mark on the floor plan.8. Also not down the type of ceiling, whether pop cutting is required or not and availability of cable tray.9. Identify if any future planning is required or not in case of under construction buildings.

LOS SURVEY

TAKE LAT – LONG BY GPS

ASK FOR FAR END TO SURVEY CO ORDINATOR

DECIDE TOWER HEIGHT( e. g POLE,RTT, GBT )REQUIREMENT( ALSO CONSIDER CUSTOMER SPECIFICATION , NOT MENDATORY )

CHECK POSSIBILITY OF CABLE ROUTING UPTO BTS LOCATION

IF PCM CABLE OR A-BTS IS REQUIRED FOR TX ,THEN MAKE NOTE THAT PCM CABLE LENGTHIS NOT EXCEEDING BY THAT OF GIVEN SPECIFICATION( UPTO 250 M).( DO NOT COMPROMISE WITH BTS LOCATION IT AFFECTS POWER CALCUTAION )

INDOOR PROPOGATION Indoor channels are different from traditional mobile radio channels in two different ways

• The distances covered are much smaller • The variability of the environment is much greater for a

much smaller range of Tx-Rx separation distances.

The propagation inside a building is influenced by• Layout of the building • Construction materials

Typical building type• Sports arena, residential home, factory,...

Indoor propagation is dominated by the same mechanisms as outdoor

• reflection, scattering, diffraction.

Page 17: IBS Training Module

ADAADA CellwCellwoorksrks

However, conditions are much more variable • Doors/windows open or not

The mounting place of antenna• On the wall, ceiling, etc. • The level of floors

In building path loss factors • Partition losses (same floor) • Partition losses between floors

Page 18: IBS Training Module

ADAADA CellwCellwoorksrks

PARTITION LOSSES There are two kind of partition at the same floor:

• Hard partitions: the walls of the rooms • Soft partitions: moveable partitions that does not

span to the ceiling • The path loss depends on the type of the partitions

PARTITION LOSSES BETWEEN FLOORS The losses between floors of a building are determined by

• External dimensions and materials of the building • Type of construction used to create floors • External surroundings • Number of windows • Presence of tinting on windows

o Antenna System used in IBS Integrated Antenna System

An Indoor area covered by one location e.g., open premises like sports

arena, railway station where BTS is mounted on the wall connected to the Integrated antenna system

Antennas Distributed Via Coax Feeder NetworkThis is the most simplified method used in IBS. It has some

advantage like low cost, flexibility in theDesign when shaping the coverage area, robust and well proven

technique Leaky Cable

This type is mainly used in Train tunnels, where it is tough to install with Coax feeder network. It also has flexible design but it is costly

Antennas Distributed Via Fibre Optic NetworkLow attenuation is the key factor for the deploying IBS thro fibre optic network. Even though it has some advantages like low attenuation, easy installation, it has disadvantages like very expensive, poor design flexibility and power supply needed for antenna units

REPEATER :

Generally used where capacity required is low.

It amplifies and converts weak signal into stronger signal by adding some gain to it.

There are 2 types of repeaters.

1) BAND SELECTIVE:

It amplifies and boost frequency of particular BAND

2) FREQUENCY SELECTIVE:

It amplifies and boost particular frequencies only (Generally 2 / 3 frequency.

THERE IS NO PROPER SADDLING, TYING OF CABLESNo Saddling/tying done on site, typical requirement is as followsi.e., every 1mtr or 1.5mtr cable is to be tied

REQUIREMENT OF EXTRA MATERIALClamps FOR Antennas/cable

Page 55: IBS Training Module

ADAADA CellwCellwoorksrks

VENDOR HANDLING1. Handover site to vendor with all details like work permission,

material storage space, proper cable routing. 2. Generate MRF for delivery of material to this site.3. Ask vendor for daily update.4. Must visit site 2-3 day in week.5. Ask all details after completion of full site.6. Get the material details from the vendor7. Get the BOM (Bill of Material) from the vendor and generate cam

Form for the site after reconciling the material

IMPLIMENTATION AUDITVisit site daily if possible otherwise 2-3 day in weekCheck installation is as par plan or changeDecide any changes in antenna location (if require according to

aesthetic, permission, cable routing etc..)

Page 57: IBS Training Module

ADAADA CellwCellwoorksrks

IBS IMPLEMENTATION QUALITY STANDARDS.1. No Extra Cable is left rolled near the BTS Equipment.2. Feeder Cable and components have to be independently & properly

clamped (saddling) to the wall or laid over the cable tray .

3. Combiner is clamped and the various cables to and from the combiner are secured properly on the Cable tray or Wall mount.

4. Feeder Installation for all the sectors should have appropriate bending radius for both 1/2” & 7/8”.

5. Connector have to be weather proofed6. Feeders & components should be anchored at fixed intervals by

saddling/cable tie7. Aesthetic rectification should be completed with cleanliness
