Most cable based ISP's have the disadvantage of being able to work with just ONE ISP at a time, thereby limiting the choice of service available to subscribers. Likewise, even for DSL based services, the entire infrastructure - i.e. from the DSLAM to the copper pair coming to your home, is owned just by ONE company - BSNL, MTNL, Airtel or Tata. Bottomline: if Tata does not have its own line going to your home, then you are not a 'feasible' subscriber.
Strangely, in the West, as well as in Pakistan, DSL providers have the option to piggyback on the telephone provider available locally - and such that the same exchange can hook up to multiple DSLAMS from multiple ISP's. So, in effect, a certain house in Karachi could use CyberNet's DSL service, while its neighbouring house could use MultiNet's DSL service - both on the copper pair owned by the public carrier - PTCL. Okay, tariffs are considerably high - but these take time to rationalise - as the subscriber base increases. But then, bottomline remains that in a situation like this - the subscriber's choice is NOT limited to what the carrier chooses for him/ her.
Therefore, what remains to be asked is this: Can a mechanism be evolved that allows a choice of multiple services over one carrier network? All said and done, phone companies can do this straightaway - by unbundling the last mile of copper pair services - and leasing out part of the spectrum to piggybacking DSL providers at a flat, regular license fee - as is done in the West. With cable, this may be a little more difficult (cost intensive) and may not be viable for cable service resellers. But then, there is no harm in experimenting.
I look forward to your views on this and how greater choice can be offered to subscribers, thereby giving more reasons to expand the broadband base.
