All About Bandwidth - Broadband In India
The recent bandwidth upgrades announcement by BSNL has everyone excited. Hari mentioned that this was the ‘hot topic’ in forums, but he linked to a silly discussion on the Digit forums with stupid Indians posting in broken English. Completely useless to us.
I poked around in the VinuThomas and found lots of interesting this that I shall quote here:
What Airtel Says
From: http://www.airtelenterprise.com/networks_alliances.html
,em>Submarine cable: We have partnered with SingTel to create the world’s largest submarine cable system- Network i2i with 8.4 Tbps capacity. This 3200 km undersea cable structure stretches from Chennai to Singapore and thereon to Tier-1 carriers on SingTel’s capacity on 175,000 km of cables. The huge capacity on network i2i is distributed locally in India through our 25,000 km of advanced fibre-optic domestic long distance backbone, providing unprecedented capacity, speed & reliability.
SE-ME-WE-4: Se-Me-We-4 (South East Asia, Middle East and Western Europe 4) is the new undersea cable connecting the Pacific to the Atlantic, and has been built with 4th generation Terabit DWDM technology. On its 20,000 km journey from Singapore to France, it lands in each of the 13 countries along the way.
In India, the cable lands at our landing station in Chennai. The new addition will complement our existing undersea cable – the Chennai-Singapore i2i – and our nationwide network in bringing you higly reliable, robust and seamless connectivity to Europe and the US East Coast. The other big benefit of SeMeWe4 is that besides benefiting the IT & ITES, it will be a boon for the BFSI (banking, financial services and insurance) segment, offering you connectivity solutions from 2 Mpbs (E1) to 155 Mbps (STM1) on SeMeWe 4. Full circuits in India will are available too.
From a blog comment Hari linked to here
Apart from a number of Indian and Foreign owned satellites that provide international bandwidth of about 54 Mbps per transponder (they usually have a few transponders each, which are also used by broadcasters), India has international connectivity on the following undersea cables:
1. SEA-ME-WE-3 (VSNL) – total capacity available to VSNL is a few Gbps. Much of this is already used up. This cable connects India to Western Europe, Middle East and East Asia (inc Japan). This used to be the old workhorse.
2. FLAG - Intercontinental, but smaller footprint than SMW3. Owned by Reliance, but by a quirk of history, VSNL owns the access points out of India. Needs the two to tango, which they often don’t. Capacity available on this one.
3. i2i – Whopping 8400 Gbps design capacity. Over 1400 Gbps immediately available. It connects to Singapore, which is a hub for many international cables. This one cable alone debunks any complaints of bandwidth ‘scarcity’. The catch, it is wholly owned by Bharti and SingTel, its partner.
4.SAFE-SAT-3 – VSNL’s alternate route to Europe via Africa, and East Asia (via Malaysia). Lots of capacity Available.
5. Tata Indicom – VSNL, connects to Singapore (like i2i), and has 5400 Gbps capacity. Launched, but awaiting security clearances from Govt of India
6. Coming Soon – SEA-ME-WE-4; VSNL & Bharti – next generation in the SEA-ME-WE family.
As you can see, all three of India’s telecom giants (Tata, Reliance and Bharti) own independent access to international capacity. There is a humongous amount of capacity available, waiting to be used, under the sea.
This kind of capacity is not matched by the quality of the “last-mileâ€, the stretch from the exchange to homes and offices. In many cities, the legacy BSNL/MTNL lines are poor quality and incapable of supporting more than a few Mbps speeds. Older Cable TV networks similarly suffer from quality problems.
New lines laid by Bharti, Tata, BSNL and others do allow higher speed access, but service offerings are tailored for the mass market which suffers from legacy issues.
In my mind, there are two reasons why higher speed broadband services are not offered in India:
a) Operators have found a ‘comfort spot’ on pricing international bandwidth; with no one ready to fight each other in this space.
b) Last-mile bottleneck creates reluctance on the part of operators to offer higher-speed services
c) India’s internet penetration is miserably low. Looking at market growth rates, operators may be taking a very conservative world view. Hence high prices for low bandwidth. For this change, PC penetration must take off sharply.
Contrast India and China, Mobiles and Internet. India has taken off on a similar path as China in terms of mobile telephony, hence the mobile boom. India’s internet penetration is nowhere near China’s, hence the broadband bore.
Another comment from the same blog post
[The following comment is from Vikram Asrani. He mailed it to me because the system was probably misbehaving. So I am posting this on his behalf.—Atanu]
What is the cost structure of the connectivity business – I think there are several aspects to this. Let us split this up into its components – connectivity from the user to the service provider, operations at the service provider, connectivity from the service provider to the internet and the speed component. Let us examine each component separately.
Connectivity from the consumer to the provider is piggybacked on phone or cable lines (when talking about DSL or cable modem). In the US at least, there is a redundant and robust networking infrastructure to provide telephone and cable lines to every end consumer. In India, while there is a telephone infrastructure, it isn’t comparably robust
(with cables hanging all around, roads being dug so frequently, improper drainage, lines are easily susceptible to picking up noise and disruption). When a network service is piggybacked on the existing
infrastructure, it adds some cost. I suspect that the incremental cost with a robust infrastructure is almost zero, while the incremental cost in India is non-zero.
The second aspect of connectivity is operational costs at the service provider (essentially efficient routing and rate limiting). This is purely a function of technology and efficiency of operation. Its hard for me to compare these two between India and the US.
The third aspect of connectivity cost is pipes and peering. The cost of available pipes is a function of whether there exists physical pipes, and is essentially about supply/demand. The more points of presence you have on the network (ie the more you peer with other service providers), the better your connectivity. I think someone has listed the pipes out of India though has not spoken about peering. My knowledge is limited to VSNL which has one fat pipe to New York (through Europe but with no peering in Europe). Its expensive to peer
with providers in developed countries. Costs are a function of 95% percentile of peak traffic as opposed to average traffic. I’m not exactly sure of why it is hard to have good pipes connecting India to the ROW and to increase peering with US network providers. I suspect there are more aspects to it than simply supply/demand.
The term speed, I think is misrepresented. There are two aspects to it. The download speed (ie the speed between the last hop and your machine) which is what is advertised by providers, and perceived speed which is also dependant on how good the service providers connectivity is to the ROW. This aspect of it is never discussed when advertising about network connectivity. The latter is what determines user experienced speeds while the former is what is discussed everywhere. I think one would require to do a detailed technical analysis to understand requirements to improve connectivity speed from India to
the ROW.
All that said, I don’t think network connectivity is expensive based on the example you gave. Your comparison is of the Bay Area vs Pune. I think the average cost of a 384 kbps connection in the Bay Area is
around $50 a month (as also pointed out by a couple of others). I myself was paying Comcast around $45 pm on a discounted scheme. The $20 and $30 schemes are essentially all promotional schemes which last anywhere from 3 months to a year. The cost of network connectivity in Pune, for a 256 kbps line, BSNL’s current charges are Rs 250 a month (was Rs 500 a month upto last month). I think Iqara has similar
charges (somewhere around Rs 300 a month). While the download speeds can be compared (256 to 384) perceived speed, uptime of the service, value added services as well as restrictions are different in both cases (like service providers in India impose download limits on a monthly basis), making the complete user experience in both cases very different. (and this is probably what matters more)
If you do want to compare costs, the way I look at it is that I could buy around 4 decent meals for the price I used to pay for broadband in the Bay Area on a monthly basis. I can buy only 1 or 2 decent meals
for the price of monthly broadband in Pune. This makes the broadband in Pune cheaper than the broadband in the Bay Area.
Conclusion
To conclude, it looks like BSNL Dataone is actually a minor player in the DSL field, which is actually dominated by Airtel since it owns most of the available bandwidth. Also it turns out that BSNL buys bandwidth from Airtel! I predict that Airtel with match BSNL’s offer and provide better plans as usual.
It’s a long read I know but if you’re really interested in the current broadband scenario (and don’t just use the net for Orkut, email and instant messenger) you will find most of the above text interesting.

It’s more worth than being on Orkut anyway. How can they offer 2 mbps if ‘Last-mile bottleneck’ is so prevalent? BSNL or any other line are dug out all the time.

Ok it was interesting.. And you have proved your point - Airtel is better.. but what a boring read. I dont know how you people read posts on my blog. Or do you?

Arun, them offering speeds has nothing to do with you getting that speed where last-mile bottlenecks are concerned. Will narrow roads cause automobile manufacturers to close down?
Sundar, it’s not hard to read your blog since you never update.
December 26th, 2006 at 7:05 pm
sorry for the irrelevant comment!
I have been reading ur blog for quite some time now
There is a chennai bloggers meet happening this weekend at Besant nagar beach….do check out about the previous meet and drop in if u are interested…..
December 26th, 2006 at 7:45 pm
I’ll think about it.
December 27th, 2006 at 9:31 am
Yeah right.
December 27th, 2006 at 2:50 pm
It’s what your post says dude. Last-mile bottlenecks causing reluctance on the part of the service providers to offer speeds, the cable lines not being able to carry more than a few mbps. You quote them and you contradict them.
December 27th, 2006 at 8:50 pm
I quote someone else and let readers derive their conclusions. I can’t quote them and contradict them? Is that a rule now? :-\
December 28th, 2006 at 8:38 am
But your conclusion didn’t include that contradiction, did it? I was just pointing it out.
December 28th, 2006 at 10:12 am
My conclusion didn’t mention it.
You can get upto 8 mbps with ADSL before you start getting errors, I read somewhere. This also depends upon the quality of the phone wires to your house. If you live in an old flat with old rusty phone wiring, you’ll get some errors.
Last-mile bottleneck refers to the fact that the final length of wire connecting you to the internet is made of copper which is not the best medium for conducting data.
