What is IBS/DAS ?
1.In-building Solution (IBS) / Distributed Antenna System (DAS) 1.Small Cell Coverage within building premises 2.Signal is restricted inside the building 3.Antenna installed inside the building 4.Low Transmit Power of Antenna 5.Smaller Antenna size

ADA Cellworks

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.

• The level of floors  In building path loss factors • Partition losses (same floor) • Partition losses between floors . conditions are much more variable • Doors/windows open or not  The mounting place of antenna • On the wall. etc. ceiling.ADA Cellworks  However.

ADA Cellworks 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 .

robust and well proven technique  Leaky Cable This type is mainly used in Train tunnels. railway station where BTS is mounted on the wall connected to the Integrated antenna system  Antennas Distributed Via Coax Feeder Network This is the most simplified method used in IBS.g. It also has flexible design but it is costly  Antennas Distributed Via Fibre Optic Network Low attenuation is the key factor for the deploying IBS thro fibre . flexibility in the Design when shaping the coverage area. open premises like sports arena.ADA Cellworks o Antenna System used in IBS  Integrated Antenna System An Indoor area covered by one location e. where it is tough to install with Coax feeder network.. It has some advantage like low cost.

5. Handover site to vendor with all details like work permission. 2. Generate MRF for delivery of material to this site. Get the material details from the vendor 7. proper cable routing. 3. 4. Must visit site 2-3 day in week. Ask vendor for daily update. Get the BOM (Bill of Material) from the vendor and generate cam Form for the site after reconciling the material . material storage space. 6.ADA Cellworks VENDOR HANDLING 1. Ask all details after completion of full site.

permission..ADA Cellworks IMPLIMENTATION AUDIT Visit site daily if possible otherwise 2-3 day in week Check installation is as par plan or change Decide any changes in antenna location (if require according to aesthetic. cable routing etc.) .

3. Feeder Cable and components have to be independently & properly clamped (saddling) to the wall or laid over the cable tray . 2. 4. Feeders & components should be anchored at fixed intervals by saddling/cable tie 7. Combiner is clamped and the various cables to and from the combiner are secured properly on the Cable tray or Wall mount. 1.ADA Cellworks IBS IMPLEMENTATION QUALITY STANDARDS. Connector have to be weather proofed 6. 5. Aesthetic rectification should be completed with cleanliness . No Extra Cable is left rolled near the BTS Equipment. Feeder Installation for all the sectors should have appropriate bending radius for both 1/2” & 7/8”.
