RailTel-Google creates Information Super-highway – jointly establish Wi-Fi Hotspots at 400 Stations

RailTel-Google creates Information Super-highway – jointly establish Wi-Fi Hotspots at 400 Stations

 Wi-Fi Hotspots Project undertaken by RailTel in association with Google is almost complete at more than 18 Railway Stations across India, out of total 400, which are declared as Smart Railway Stations by Ministry of Railways

New Delhi: Indian Railways and Google has joined forces to create India’s largest network of free WiFi across 400 railway stations, pan India.

As per the details obtained, first 30 minutes of this service would enable high speed Internet, after which the speed will drop, but the connection remains active.

This special partnership has been named as ‘Project Nilgiri’; and aims to use Google Fiber technology to provide high speed Internet service.

But the masterstroke which Google has played this time is their partnership with RailTel, to access infrastructure and platform. Indian Railways had announced earlier that they are working on a plan to provide WiFi based Internet across 400 railway stations. But now, the plan looks concrete.

Indian Railways in association with RailTel has currently undertaken a pilot project in association with Google under the code name of ‘Project Nilgiri’ under which in phase 1 we will be setting up Wi-Fi hotspots at approximately 400 stations across India over a span of 4 months from now,” said a source requesting anonymity.

RailTel Corporation of India is a public sector unit, having massive access to connectivity and infrastructure. As of now, RailTel’s network passes through 5000 railway stations across India, connecting 63,500 kms of railway track!

RailTel’s optical fiber cable has already been laid across 32,500 kms pan-India; work is in progress for 29,500 kms. As per Wikipedia, RailTel has “state of the art multimedia telecom network using SDH/DWDM-based transmission systems and high end routers for MPLS-IP network.”

The Wi-Fi work has already been executed at Sealdah, Guwahati, Bhubaneswar, Patna Jn., Raipur, Ranchi, Jaipur, Lucknow (NR), Lucknow Jn. (NER), Hazrat Nizamuddin, Allahabad, Gorakhpur Jn., Ernakulam Jn., Kacheguda, Vijayawada, Mumbai Central (Main), Pune and Bhopal Railway Stations

And the best part is that, DoT has already allocated 2.7 GHz band to RailTel for launching broadband and other Internet based services.

Last year, we had reported that Google Fiber may enter in India, promising a dream-come-true speed of 1 GBPS, something which is unheard in India. Reports emerged that Telangana Govt. may roll out Google Fiber services in the state as well. But the biggest problem is licenses for becoming an ISP in India, and Google may not agree to pay billions of dollars for the same. However, after their association with RailTel, the licensing problem may be taken care of; and actual broadband along all the railway tracks and railway stations may now be provided.

Existing ISPs in India like Airtel, Tata DoCoMo and Reliance may find this news somewhat disturbing; as Google and RailTel can make some serious inroads with such a huge infrastructure coverage and technology. This is certainly one of those path-breaking moments for the Indian traveler and Internet user.

Execution Methodology of Wi-Fi Network at Railway Stations by RailTel and Google:

Fiber Switches of make D-Link DGS-3000-28SC were provided by RailTel for deploying at each Foot Over Bridge, Concourse areas and other strategic locations for Platform and Stations Coverage to provide Wi-Fi access.  All fiber switches are inducted into the master ring of fiber switches as per site topography/ requirement and in the Network, all fiber-switches are connected in a ring configuration pattern. The Fiber Switches have been aggregated on the Aggregator Switches (Juniper ACX 2200 Routers) which are supplied and installed by RailTel in its POP locations. RailTel have provisioned dual ACX 2200 Routers for every station which are dual homed with MPLS Routers.  Access switches are PoE enabled and connected to the Fiber switches using fiber and located broadly as detailed in the diagram above, in STAR configuration with the Fiber Switch.  For platform lengths of more than 700 mtrs, a total of 6 nos. of Access Switches were considered. For coverage in concourse areas near the station platforms, APs are connected to the Access Switch collocated with the Fiber switch.

Google have supplied and installed Access Points (Radio) of Cisco Make (IWE 3702) which were PoE enabled and connected to Access Switches using Cat 6 cables (maximum distance should not be more than 90m).  Google supplied 2 nos. of Access Points connected to a Access Switch and depending on the necessity, Google have supplied additional POE Switch in the same rack, alongwith the UPS supplied and installed by Google for uninterrupted Power Supply at each of the Platform/Concourse. Platform UPS are collocated with the Fiber Switch on the Platforms / Foot over Bridges. Overall, Google have supplied Racks for Fiber Switches, Access Switches, Cat-6 Cable for wiring of Access Points from Access Switches and UPS for Fiber Switch and Access Switch, and the POE enabled Access Points and then installed Access Switch racks, APs, laying and connecting of Cat-6 Cables between Access Switches and APs.

RailTel have supplied Fiber Switches and Access Switches and have installed the Fiber Racks supplied by Google and bifurcated the work into two phases – viz. in Phase-I, RailTel have installed the Fiber Racks, UPS, commissioning of Fiber switch ring and connecting UPS Supply to power up Fiber Switches.  In the Phase-II, as per the cable route plan drawings, installed Access Switches in POE racks, which were supplied and installed by Google and provided Optical Fiber connectivity between Fiber and Access switches using BiDi SFPs.  Every Access switch is dual homed with two fiber switches.  The UPS supply is extended to Access Switches.

RailTel bags prestigious MPLS-VPN Order from State Bank of India

Mumbai: Western Region of RailTel Corporation of India Ltd (RailTel) have bagged the prestigious order from India’s largest banking organisation – State Bank of India (SBI) for connecting 3000 SBI branches (including the associate banks) spread across the country.

SBI has placed the Letter of Intent on RailTel on nomination basis. The total value of the deal could be more than INR 60 Crore per annum, said a source from SBI/Belapur on the condition of anonymity.

As part of the deal, RailTel will offer a premium class of services to SBI in 3000 branch locations on the MPLS-VPN.  The delivery at branch sites will be envisaged through OFC/RF whichever is feasible, on RailTel’s networki, however in RF connectivities, RailTel will be using its existing Digital/Analog Microwave towers as well as by constructing new GBTs with the help of the empaneled System Integrator with whom the Rate Contract was signed.

RailTel’s MPLS VPN will support any to any connectivity of the SBI and will be a closed user group for Bank and will not have any physical and logical interference with other customers of the TSP or Internet route/traffic. The architecture used for the complete solution will be end to end enabled with layer-3 routing domain (end to end transparent layer-3 routing using static and dynamic routing) with Latency not more than 120 ms (End to End) for a 1500 byte packet size measured for a minimum of 1000 packets.

SBI also sought special approval from the Strategic Executive Board to empanel RailTel in lines with BSNL to directly place order for Primary 2 Mbps MPLS to branch without tender.  For secondary / alternative links, SBI has already floated a RFP and online reverse auction was conducted on 15th July 15.

State Bank of India has a Wide Area Network (WAN) known as State Bank Connect (SB Connect), connects its branches/offices and that of Associate Banks predominantly on BSNL MPLS which connects around 20000 branches/offices, and additionally around 3500 branches connected through VSATs. The Managed Services for this entire existing network is with Dimension Data India Ltd. (an NTT Group Co.,).  SBI sought to provide alternate connectivity to about 22000 domestic branches/offices of the State Bank Group by June 2016, and for this purpose it is proposed to use Wireless solutions from Telecom Service Providers, except BSNL/MTNL.  State Bank Group (SBG) for the limited purpose of this RFP means State Bank of India, and it‟s Associate Banks.

As part of the deal, RailTel shall submit the details of the technology used related to end to end connectivity from the branch to SBI data center in the following domains:

  • Devices used for end to end connectivity
  • Different type of authentication used at different points of connectivity
  • Level of security and authentication process for providing the connectivity
  • Details of the features available/integrated for Guaranteed availability of service for providing end to end connectivity even during failures at multiple points between branch to Data Center.

The Bank will arrange for UAT & SAT for each type of technology offered by RailTel and clearance will be given only if the Bank finds the technology to be acceptable from a functional, performance and security point of view.  The links at the data center shall terminate on a layer 3 device which will be provided by the Bank. The responsibility of the RailTel for managing the connectivity shall be from the Branch/Office site up to the layer 3 devices, provided by the Bank at the Bank’s data centers. Laying of cables up to the device shall be the responsibility of the RailTel.

The duration of the contract is valid for five years from the date of first Purchase Order yet to issued by SBI. RailTel shall have the option to agree for the extensions of the solution (from the date of expiry of the contract) for any period not less than one year at a time and for any number of times at the request of SBI and at mutually agreed commercials.
