  14. 14. STEPS IN IBS SURVEY1. Study the building architecture, with the help of floor plans & guidance fromBuilding authorities2. Understand the requirements need in terms of Coverage, Capacity, futureSubscriber 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 thefloor 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 notand availability of cable tray.9. Identify if any future planning is required or not in case of underconstruction buildings.
  15. 15. LOS SURVEYTAKE LAT – LONG BY GPSASK FOR FAR END TO SURVEY CO ORDINATORDECIDE TOWER HEIGHT( e. g POLE,RTT, GBT )REQUIREMENT( ALSO CONSIDER CUSTOMER SPECIFICATION , NOT MENDATORY )CHECK POSSIBILITY OF CABLE ROUTING UPTO BTS LOCATIONIF 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 )MAKE TERRACE LAY OUT
  16. 16. INDOOR PROPOGATION Indoor channels are different from traditional mobile radio channels intwo different ways• The distances covered are much smaller• The variability of the environment is much greater for a muchsmaller 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.
  17. 17.  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
  18. 18. 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 theceiling• The path loss depends on the type of the partitionsPARTITION 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
  19. 19. ANTENNA SYSTEM USED IN IBSAntennas Distributed Via Coax Feeder NetworkThis is the most simplified method used in IBS. It has some advantage likelow cost, flexibility in theDesign when shaping the coverage area, robust and well proven techniqueLeaky CableThis type is mainly used in Train tunnels, where it is tough to install with Coaxfeeder network. It also has flexible design but it is costly

GENERAL IMPLEMENTATION ISSUE IN IBS OPEN CONNECTIONAntenna, splitter, coupler port is open COUPLERCouple port/through port is reversedInput port/through port is reversed LABELINGAll the splitters and couplers should be labeled for easy identification ANTENNA PLACEMENT OR ORIENTATIONS IS NOT AS PER PLANShift in antennas if any due to route / customer problem. 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
  55. 55. VENDOR HANDLING1. Handover site to vendor with all details like work permission, materialstoragespace, 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 Formforthe site after reconciling the material
  56. 56. 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 toaesthetic,permission, cable routing etc..)
  57. 57. IBS IMPLEMENTATION QUALITY STANDARDS.1. No Extra Cable is left rolled near the BTS Equipment.2. Feeder Cable and components have to be independently & properlyclamped(saddling) to the wall or laid over the cable tray .3. Combiner is clamped and the various cables to and from thecombiner aresecured properly on the Cable tray or Wall mount.4. Feeder Installation for all the sectors should have appropriatebending radiusfor both 1/2” & 7/8”.5. Connector have to be weather proofed6. Feeders & components should be anchored at fixed intervals bysaddling/cable tie7. Aesthetic rectification should be completed with cleanliness
