I just found out this interesting presentation by RailTel where it wants to use a PPP model for broadband using RailTel OFC and RoW infrastructure. It's at
http://www.railtelindia.com/pdf/PlanningCommpresentation.pdf
They've been wanting to do this for years, but the price at which they want to lease out infrastructure is magnitudes higher than it costs to build - they still want to charge out the same rates they could get 5 years ago, despite falls in prices everywhere else, including the cost of materials and everything else too.
One weird thing is that RailTel wants to provide Internet bandwidth themselves; I am not sure if it allows partners to use their own Internet bandwidth.
It does, and some providers do it already.
Another weird thing is that RailTel has 800 towers; RailTel doesn't have any wireless operations as far as I know. Maybe the towers are for the roll-out of GSM-R in Indian Railways. Or maybe the towers are being used in a sharing arrangement with cellular operators which use RailTel infrastructure.
They have their own wireless infrastructure for their own use - that's what most of Railtel's operations are for. They've built all this fiber, and now they're utilizing it in such a way that it's paying for itself, but not really making them any money, even though huge amounts of the available capacity is sitting idle (due to the aforementioned prices).
Will this plan/project for broadband be useful to Hayai?
It would, and I'd love to start using it. I've been to speak with the GM of Railtel's Western division on numerous occasions, without a great deal of success as yet - they're certainly interested, but it comes down to price: if only they didn't charge like wounded bulls for the capacity.
The way it is now, it's far cheaper for me to get say, VSNL to deliver me bandwidth in a multi-drop situation than to get everything delivered to 1 or 2 main spots and then distribute it myself; that is to say, if I order for example 100gbit/s from them, they deliver 25gbit/s to Mumbai, 25 to Delhi, and 10 each to Hyderabad, Pune, Kolkata, Chennai & Bangalore respectively... or whatever is needed, rather than the slightly more ideal situation of getting 100gbit/s to Mumbai and distributing it however I see fit.
Are BSNL and RailTel the only major providers of inter-city traffic? Do other telecom operators always lease bandwidth through these companies or do they also lay out their own fiber between cities?
BSNL and Railtel are among the largest in terms of route-kilometers, but VSNL,
Tata, Reliance and a number of other companies across various all have got fiber going all over the place - and weirdly, there's "still not enough" for everybody (which to me actually means there's not enough at reasonable prices).
