12:40 PM -- Some commentators are arguing that Google (Nasdaq: GOOG) should take a step beyond Android and the Open Handset Alliance in 2008 and build its own 4G network in the U.S. (See Analysts: Google Plans Lack Substance .)

I remain to be convinced, however, that Google would be able to do a better job at running a nationwide network than the incumbents. This isn't child's play, folks!

Consider the teething troubles many users reported when Google launched its municipal WiFi network in Mountain View, Calif. People complained about slow speeds and poor connectivity from the new technology. That's just one city, and there are plenty of similar issues that will crop up in deploying 4G technology in the 700MHz band. (See WiFi Outlook Cloudy in Mountain View.)

That is not to say that Google won't make a play -- likely as part of a consortium -- for the "open access" C band of the analog TV spectrum when it goes up for auction in January 2008. The search giant has already said as much in public comments. I imagine, however, that the firm would be better off striking a mobile virtual network operator agreement with a carrier partner rather than trying to go it alone. Sprint Wireless (NYSE: PCS) and T-Mobile US Inc. are already onboard as part of the Open Handset Alliance, after all. (See Google Makes Mobile Move.)
