• It’s a first step of deployment project in which we check all parameters those are required for eNB installation like measuring lengths of cables, checking the grounding, power, space availability for network element.
• Cable Lengths: – Short cable can delay the installation or if too long can affect the project cost &
quality.
• Site Infra: – Site Infra should be as per site requirement, if not, it affects the project timeline.
• To reconfirm the RF planning’s requirement and the data in TSSR

(Technical Site Survey Report).
• Note– P1 sites are the sites built and owned by RJIL, also called as ‘own’ sites. – RP1 sites are the sites that will be built by Rcom and also called as ‘Shared or Co-
Lo’.
