Deutsche Telekom Faces Same Challenge as Many U.S. Service Providers

Most telecom executives, especially those facing growing competition from cable operators, have had to ask hard questions about their options for upgrading access networks. The simple fact is that a full replacement of the network to fiber to the home technology is expensive. 

Japan's Bank Nomura estimated the cost of a digital subscriber line upgrade, in areas where Deutsche Telekom needs more speed to counter cable operator high speed access offering, at around 4 billion euros ($5.1 billion), while a full upgrade to fiber to the home, across Germany, could cost around EUR80 billion, or perhaps $102 billion.

So Deutsche Telekom plans to selectively upgrade, using a faster form of digital subscriber line technology, in those areas where competition is most fierce. The vectoring approach provides a dramatic boost in speeds. 

Some would argue that Deutsche Telekom should simply rebuild its network using fiber to the home, essentially creating a "future proof" network. 

The problem, some would say, is that the financial return from doing so is questionable, at some level. Mobile substitution is one issue. The bigger problem is that the basic business case, overall, is much tougher. 

A shift of end user spending to mobile services means less potential revenue from a mix of services, ranging from voice to high speed access to video. Also, incumbent market share is far lower than it once was. In many cases, established operators have 30 percent to 40 percent market share, where they once had virtually 100-percent share. 

That means a complete upgrade is bound to "strand" a significant portion of those assets, which will not have revenue attached to the lines.
