An interesting thing happened in 1999. The unit price of a long-distance voice call to consumers, which had been falling since the early 1980s, finally crossed over the cost curve and long-distance voice became a loss leader. This eventually led to the acquisition of the long-distance giants by the regional Bells. It was certainly one of those pivotal events in telecom history, but another 1999 event might be even more important.

That also was the year when profit goals for the carriers shifted from wireline to mobile, and there’s evidence now that the mobile horse may not race much longer.

If something makes less money — or is likely to — producers are apt to invest less in it. The mobile players started to slow-roll their capital builds last year and that had an immediate impact on network equipment vendors with the most exposure in the mobile space. At least once in the last four quarters, Alcatel-Lucent and Ericsson blamed mobile market conditions for their disappointing quarterly numbers. They’re likely to cite the same problem in the next four quarters, too.

The core of the problem with mobile is that FCC data tends to show that communications spending is a zero-sum game; it makes up about the same percentage of household budgets as it did 20 years ago. All of the advances of networking are competing for a share of a static pie. When you add to that the impact of over-the-top services such as VoIP that create competition for incumbents without generating profit to build additional network capacity, you have the formula for some major challenges. The big issue for the industry today is how those challenges will be met.

Operators have really only two choices; cut costs or create new revenue-generating services. The latter of these is more attractive on the surface, but it still runs into the problem of static household budgets. The cost-cutting option is therefore more appealing, but three of every four cost dollars is operations and administration, and much of that is customer acquisition, retention and care. In the capital budget area, it’s hard to find spots to cut.

The operators may have an answer to their problem that straddles the cost/revenue fence: fixed-mobile convergence. FMC has been promoted as a benefit to customers, a way to create unified calling plans that roll calls between wireless and wireline. It’s been seen by operators as a way to establish a new generation of capital programs, including the ever-popular IP Multimedia Subsystem (IMS). That makes equipment vendors — particularly IMS supporters — smile. But none of this is the real driver; that honor goes to “picocells”.
