please confirm about the exact equipment along with their technical specifications for the following activities.
1. CW Measurement
2. Spectrum Measurement.

• Receiver with fast scanner ( The receiver scanner rate should conform to the Lee Criteria of 36 to 50 sample per 40 wavelength)
• CW Transmitter
• Base Station test antenna ( Omni-directional )
• Accessories ( Including flexible coaxial cable/jumper, Power meter, extended power cord, GPS, compass, altimeter etc ).

BAND – All the CW equipments (2.3 GHz).
Both the testing will be for LTE

Scope of Work for CW measurement

Identifying at least 30-35 sites per city for CW test to cover all clutter types and morphologies adequately for model tuning purpose.
Before conducting CW tests, a site survey will have to be carried out for each site and Survey Form to be filled (as per Annexure A) to verify the locations of site, space/power availability, reassess the site feasibility, pole locations etc.
All the CW equipments (2.3 GHz) and accessories to be arranged by Vendors. It is mandatory to use the calibrated transmitter and receiver equipments. Calibration should not be older than 1 year.
Snapshots of installation of CW test equipments (2.3 GHz) and power measurement should be taken before and after the drive test, Survey Form should be updated with relevant information including actual transmitter antenna height. Carrying out a detailed drive test as per the route provided. Special care to be taken, not to leave out any of the routes and collect maximum of data.
Indoor penetration loss measurements should be taken for at least 10 samples for each clutter category (Skyscrapers, dense urban, and medium dense urban, low- dense urban, industrial, rural) in the city. The sample should be taken approximately 2 meters from the wall with average taken over period of 1 minute.

Scope of work for Spectrum Measurement
Carrying out a drive test with RF scanner as per the route provided. Approximately 2000 Km per city . The scanner shall be configured to scan 25 MHz bandwidth in 2.3 GHz band. The centre frequency for the scanner in any given service area (telecom circle) shall be communicated at the time of award of contract. Thus 2.5 MHz of guard band on either side of the 20 MHz BWA channel will be covered in spectrum scanning.
