Features of Radio trunking implemented for Features of Radio trunking implemented for Mundra Delhi Pipeline of HPCLMundra Delhi Pipeline of HPCL
A private call can be made i.e. one to one communication. Possible to make group call i.e. communication among a group. Telephone interconnect is available i.e. call between landline &
Radio. Emergency call i.e. override of any call in network for handling
operational emergency. Multigroup calling can be made i.e. addressing to many group at
any given point of time. Dynamic site assignment i.e. optimum resource allocation of
network for communication of Radio. Can be used while roaming anywhere in pipeline route i.e. any radio
can be used along the pipeline network. Ensure call continuity i.e. call doesn’t drop when moving from one
tower to another tower.
Benefits of Radio Trunking system for Benefits of Radio Trunking system for pipelinespipelines
It is a wireless dedicated private network throughout the length of the pipeline.
It provides round the clock seamless communication between security personnel at remote location along the entire route of pipeline to control room for enhanced pipeline security.
We can have customized wireless private network among security personnel & control room along the route as per operational requirement.
Being a dedicated private network, Hence no dependency on service providers.
Advantages of Radio Trunking over Advantages of Radio Trunking over conventional VHF communicationconventional VHF communication
• It is semi-duplex communication.• It provide encrypted communication i.e. highly
secured mean of communication.• Longer range of communication.• One to one call between Radio can be done.• Online monitoring / control on use of Radio. It
can be made defunct incase of theft / lost to avoid any unintended / malafide use.
• Call among group can be done.• Roaming network for uninterrupted
communication.
Steps for implementation of Radio trunking Steps for implementation of Radio trunking
To obtain pairs of frequencies from WPC as per site requirements.
To obtain SACFA clearance for towers height. Interfacing of OFC with VHF Radio’s. Construction of towers for installing the
antenna. Installation of base station / repeaters. Battery banks & chargers for back up.
Scope for Future integrationScope for Future integration
Migration to digital radio Trunking system.
Wireless data communication through VHF.
GPS enabled hand held radios for use in security position tracking system.
Wireless communication of PSP values from field.
