RF Survey

The ultimate goal of a RF site survey by Himtel is to acquire ample information to determine the number and placement of access points that allows optimal coverage throughout the facility.

RF site survey is carried out in the following steps:

  • Collect list of Nominals to be surveyed from the customer. In case of new town surveys where Nominals are not provided, Himtel will survey the town and provide a nominal for suitable site location
  • Use the survey report template forwarded by the customer
  • Identify physical location of the proposed nominal and locate 3 candidates (maximum) for each nominal, as per search ring size suggested by the customer
  • Survey the site for RF suitability
  • Record Latitude and Longitude, building height etc. of the proposed candidates
  • Estimate and provide required GSM Antenna heights and orientation, proposed tower/pole location (s) will also be marked on a rough sketch of the building (rooftop) or ground site (for each candidate)
  • Take site photographs (360 degrees panoramic view and building/site elevation) for each candidate as given in the survey template by you
  • Record physical addresses of the candidates and site owner/manager contact details (where available). Complete the Site Survey Candidate evaluation report

Line Of Site (LOS) Survey

The ultimate goal of LOS survey is to have MW connectivity between the two sites to ascertain the Line of Site clearance. The LOS survey is carried out physically checking the terrain between the hop and selecting the sites for acquisition. The survey is highly critical because any failure in LOS can lead to a delay in project and a subsequent loss of account.

LOS survey is carried out in the following steps:

  • Collect Nominal's of proposed site and those of the nearest locations to which customer proposes the LOS connectivity & verification
  • Record latitude, longitude, building data, obstruction data and surrounding terrain data on the LOS Survey Template
  • Generate LOS Path Profile for the proposed Link using Pathloss 4.0
  • Generate LOS report for the proposed Link using Pathloss 4.0. Conduct physical survey of the hop to identify any field obstructions and verify the LOS path profile
