Now, no more call drops even inside Metro tunnels
Delhi Metro commuters will soon get the shared mobile (cellular) coverage (2G/3G/4G) in tunnels and underground stations of ITO-Kashmere Gate (Line-6 Extension), Netaji Subhash Place-Azadpur (Line-7) and Naraina Vihar.
In order to provide the shared mobile (cellular) coverage the telecom operator will use ‘In-Building Solutions’ (IBS) which is a concept that will be offered by a single telecom operator (selected by the Delhi Metro Rail Corporation) having a single common infrastructure with the help of which all existing and upcoming mobile operators can serve their customers in an easy and efficient manner.
The IBS will also offer shared in-building solutions for various types of telecom operators such as GSM/CDMA technologies.
The telecom operator will set up and manage the commonly shared IBS at the licenced premises and will provide the services of IBS to various telecom operators and other agencies and charge them appropriate licence fee.
The selected telecom operator in turn will pay a fixed amount of monthly licence fee and other charges along with applicable taxes, quarterly in advance, to DMRC.
The IBS coverage will be provided through distributed antenna system and it shall be left to the selected bidder to decide on the technology solution that fits best in meeting the coverage criteria while keeping in view the building profile and ground realities for mobile operators.
The telecom operator will also provide radio frequency signals for the use of the Delhi Police in the range of 800MHz frequency band (806-870 MHz) conforming to APCO P-25 standards. In addition to mobile signal, mobile service provider will also propagate this RF signal in the tunnels and station areas by using infrastructure meant for mobile coverage.
For this purpose mobile service provider will integrate and interface with the nominated agency of Delhi Police in order to have a reliable network and good voice quality throughout the tunnel and station area for the Delhi Police wireless system.
