Week 8 reading reflection

Since 2005, I have tried to switch all of my phone calls to Skype. Now that　I use Skype, it has drastically reduced my phone bill, from hundreds of　dollars a month  to under one hundred.
Also, most of my phone calls are made on my cellular phone. My phone calls　ratio of the 　landline to Skype to my cellular phone, is briefly 1 to 3 to 6. In other words, my usage ratio of voice to data is 1 to 9. I think this ratio almost reflect the future of telecommunication. As Christensen
mentioned, established wired services are expected to face a hard time when competing with data services. I basically agree with Christensen’s conclusion that the telecommunication industry will be shrinking. I think those telecommunication giants such as AT&T and SBC will survive and dominate the industry.

The infrastructure telecommunication possesses is a huge resource such as the existing infrastructure that mobile technology largely relies on.  As long as this extensive infrastructure stretches across the whole country and is under the possession of telecommunication companies, mobile companies must stay dependent on telecommunications companies..

2,What do telecom companies need to do in order to compete with entrants in
the Voip technologies?
