NPC MOBILE COVERAGE SOLUTION

RECENT TOUGH  PROJECT BEING DONE BY NPC

LOCATION:  TAPOVAN , LATA VILLAGE UTTRAKHAND , L & T  HEC  PROJECT 57X3 Mw 

 PRECISE LOCATION OF AREA


Mobile boosters  are device which  are  used to  Boost  very weak signals  inside building, basements, metal  cabins etc .  These solutions are  easy  &  nowdays often sold as kits  on indian online portals .
                                                        But what to do in  situation  where  one need mobile coverage in a big area as 4 sq kms , & there is no  mobile signal at all &  people in such area often go to places 3-4 kms away on high poing to get one  BAR on his phone .. NPC  engineers  has made this possible for  Larson & Tubro construction company , where their  employees are constructing a  Hydel power project for NTPC  near   Tapovan , Joshimath. The 250  employees of L & T   were  without  any phone connectivity since last 2 years . 

                                               Before NPC 12 companies  tried to  provide  the solution  but most of the company failed . These  types  of solutions requires  intense studies like  area geography study, Intense knowledge of heigher & lower  frequency behaviour  related to harsh weather conditions , intense Radio parameters  calculation abilities , &  extra ordinary   mental ability   to work in most  harsh environments.  NPC engineers  & technicians  have proved  that  they can bring  wireless network   of any kind  even in Globe's  most remote area  Like  wild Himalayas .

 THIS AREA  WAS SURROUNNDED BY HIGH RISE LOWER HIMALYAS  FROM ALL SIDES

 WEATHER CONDTION IS SO HARSH WITH HEAVY  CLOUDY ENVIRONMENT

 LARSON & TUBRO   HAS  CONSTRUCTED  MINI COLONY WITH ALL FACILITIES  LIKE WEATHERPROOF HOUSE, FOOD COURT, TV  etc   FOR THEIR EMPLOYEES 

 SATELLITE PHONES WERE ONLY ONE SOURCE OF COMMUNICATION   IN THAT AREA , BUT EVERY ONE CANT  GET ACCESS TO THE SAME  ALL THE  TIME

 ANTENNA INSTALLATION  IN PROCESS

 ACHIVING SIGNAL STRENGTH OF  -108 dbm 

 ADJUSTING DIRECTIONAL ANTENNA , AFTER DOWLINKING RECEIVED 

 UPLINK WAS  FAILED ... & COMMUNICATION WAS  SIMPLEX ... ONE WAY 

  

WITH THIS CUSTOMISED ANTENNA  FOR  LOWER FREQUENCY  , NPC GUYS ACHIVED FAIR UPLINK LEVEL  SEPARATELY &  later COMBINED BOTH THE  PARAMETERS USING  Up-Dn COMBINER

 ANTENNA  INSTALLATION AT POSSIBLE  HEIGHEST POINT

 ANTENNA INSTALLATION AT POSSIBLE HEIGHEST POINT 

 ANTENNA INSTALLATION AT POSSIBLE HIGH  POINT

 MOUNTAINS OBSTRUCTED  MAJORITY OF   RADIO SIGNALS 

 USED  CAMERAS  &  LOCAL PHYSICAL MAP    TO CALCULATE  ANGLE   OF RADIATION FROM NEARBY TOWER 

 MOBILE  PHONE  WORKED !!!!!!!!!!!!!!!!!!!!

STILL NEEDED  LARGE AREA   OF  COVERAGE &  NPC  DID   THAT IN 24  Hrs , TOOK 48 Hrs  FOR AREA SURVEY  & PICKING RIGHT PRECISE POINT RADIO SIGNAL STRENGTH , IT WAS LIKE  FINDING  A PEN  ON FOOTBAL GROUND  FROM  HELICOPTER

LARSON  &  TUBRO AWARDED CERTIFICATE OF  WORK ACCOMPLISHMENT TO NPC  WIRELESS SOLUTIONS ..

 RAJAT MATTA   & SACHIN KUMAR ( BELOW)  HAS PLAYED  IMPORTANT  ROLE IN MAKING THIS   CLOSE TO IMPOSSIBLE TASK POSSIBLE ..
