3g

Yesterday I was driving and radio was pretty boring. Next, I connected cell phone to car’s stereo (I use a PT-750 to wirelessly connected my devices to car’s audio system). Next I tuned into Gaana.com app and experience was overall good. The way whole setup was working itself is a wonder - wireless profiles keeping layer 3 link (IP address of device) consistent and handovers happening on layer 1. On top of that a while world of backbone routing across AS9498 backbone the hosting provider’s network of the app. Now an interesting thing in this setup was the IP allocations. I that IP allocated by Airtel was 100.92.215.253.

Today I read in news about Govt’s decision to finally end inter-circle roaming agreements between Airtel, Vodafone & IDEA. Well, the case is not new. It has been up with doT from over months and got highlights when CEO’s of all 3 firms wrote letter to Prime Minister of India for his intervention.  

Little background

In 3G auction held in 2010, none of the operators got pan India spectrum across 22 telecom circles. Most of them have license in around 10 circles (few in 9, few in 11 and so on) and thus no one can provide full Nationwide 3G coverage.

Today, I was reading New Telecom Policy from Dept. of Telecom. Must say I am disappointed. Everyday I hear a new story on 3G & LTE in India. About wireless we all know that due to super limited spectrum, it’s good only smartphones. Hard to call even LTE as an alternate even to DSL. LTE has yet to come, but still it will hardly compete with DSL in tier 3 cities and rural India. For tier 1 cities like Delhi, Chennai, Bangalore and tier 2 cities like Gurgaon, Jaipur - broadband still suffers badly and we all know but just not accepting that wireless broadband is not way out to that. I am not against wireless broadband. I totally agree to fact that for mass deployment wireless is way to go but I strongly feel that another serious effort is needed in wired broadband connectivity. I am happy to get 2Mbps connection via 3G on my Idea cellular phone, and I don’t really complain for it’s cost because of spectrum crunch and all but I feel super surprised on fact that I get 512Kbps capped broadband on DSL when technically it can go over 16Mbps easily. It’s hard to comment on how well fiber connections to Gram Panchayats will perform. All we can say it’s good and nice initiative given they don’t create parallel infrastructure. But why Govt. is missing out demand in big cities where wired infrastructure is “decent” or can be made decent (based on demand)? I don’t see any good efforts being made by Govt. for improving broadband speeds or connectivity by making maximum use of existing copper infrastructure. Working professionals in cities like Gurgaon/Chennai still suffer badly for “decent” broadband while most of them could have given broadband - demand & technology - both of things are there. Just missing willingness on side of Govt. What’s point in FTTH now which “can” give 1Gbps speed given one is ready to pay ~$1500 a month for that sort of speeds?  

Recently lucky mobile users in Haryana got MNP i.e Mobile Number Portability.

I too ported my number out from Airtel to Tata Docomo. Reason remains the super slow GPRS network (yup gprs, not even upgraded to EDGE in most of Haryana) and crazy service activation followed by irritating sms’es.

Here’s my experience with MNP:

It took around 20 days in porting of my number, and technically speaking - process is yet not (hundred percent) completed even after a month! One of the problems with system is that whenever one requests for a porting code, it is valid for 15days. If we request for porting code again (via sms) we get same code, with same validity. In my case, I request for code, but I submitted documents for porting after 13days of my initial request. On the day of submission, I requested for code again, and got same code which was expiring after 2days. I did informed retailer about it, but he had no clue. Eventually I submitted form. Next, documents reached company by 16th (or to the middle guy), and they triggered request for porting on 16th day with same old code. Result: Port out request failed, because porting code was expired! It took me over a week to realize that, and eventually I submitted documents again. I submitted documents on Monday, and on a fine thursday evening I realized that I didn’t got any call or sms that day! Later, I found I was even not able to send any sms. Outgoing calls were going fine via Airtel connection. I got clue, and tried using Tata Docomo sim card, and it worked! All was OK other then fact that I was not able to recieve calls from Airtel users on Tata’s sim. Callers were getting message - “The Airtel number you have dialed is switched off!” At this point of time I realized a big problem - due to some bugs in system, new carrier actually accepted my number, while Airtel has yet not ported out my number. Good was that I started getting calls even from Airtel users within a day. Logically speaking all was going OK, other then fact that my Airtel connection still works for outgoing, and even at the time of blogging (after a month of porting) it’s still up! Tata Docomo customer support has no clue about it while Airtel support always requests me to visit Airtel relationship center to get this fixed. (Why really? Can’t they do this ONLINE?!)

So, finally 3G is set to launch in India from Private operators. One of my friend came to me and asked:

“So what should we really expect from 3G? End of wired broadband?”

Very nice one!

Short answer - NO, NO yet!

It’s quite strange to see, how users are taking 3G. Actually it has been largely “overestimated” technology, specially from Indian media. Let’s first try to understand - What exactly is 3G? Without going into geeky definitions - 3G is simply upgrade from 2G. It uses higher frequency, and thus has more spectrum available for more bandwidth. That’s all. One important thing we need to understand is - 3G is more or less just a last mile technology i.e it connects telecom network’s exchange to consumer’s device. Mostly 3G, 2G, landline network, and broadband network - all share same core network backhaul. Western countries who did deployed 3G many years back are going into hybrid path of taking 3G to 4G apart form offloading peak data to (wired) broadband networks. They are promoting use of wifi, bringing new gadget FemtoCell. At this time, it doesn’t makes sense to say - 3G is everything! Latest capping on uncapped 3G plans by AT&T is a good example of that.
