Hardball 11/20/09/13:00 GMT: NSN Likely for NT’s Optical Assets– Infinera Entry?

November 20, 2009

One at a time, please: Nortel delays one auction because of another | localtechwire.com

Nokia Siemens Networks desperately needs to establish a sizable public network presence in North America. Even if Ericsson places a bid, NSN appears to be the favorite to get Nortel’s optical assets. There has been speculation about Infinera entering the fray.

Hardball 11/19/09: Kiss of Death for Clearwire?

November 19, 2009

Clearwire: 'Google Believes in Us' | www.unstrung.com

Google’s lack of investment in the last round speaks volumes. As we have said in the past, no company does as much agonizing cost analysis as the search engine provider. We still believe that if Clearwire does survive, it will be with a far less ambitious, targeted metro approach.

Hardball 11/18/09: One Last Kick in Pants from WV to VZ Before Parting

November 18, 2009

West Virginia protests Frontier's Verizon acquisition | www.fiercetelecom.com

The gloves are coming off one final time between Verizon and West Virginia.  The state is probably going to be so relieved to get Verizon out that it will likely play ball with Frontier.  It would hardly be an exaggeration to say that the relationship over the years between the two parties has been acrimonious. 

Hardball 11/17/09: AT&T's Version of Keystone Cops

November 17, 2009

AT&T Rebuts Verizon Ads, Again | blogs.wsj.com

Nothing illustrates more the state of disarray at AT&T than this bungled attempt to dispute Verizon Wireless’ claims. AT&T apparently even has trouble settling on a unified public relations/marketing response. The service provider just did not want the world to know about the disparity in 3G coverage between the two carriers.

Hardball 11/16/09: Infinera Lobs Up Some More Softballs

November 16, 2009

Infinera Named Second Fastest-Growing Tech Company in North America | money.cnn.com

Infinera’s statements continue to make it very easy to hit them out of the park. It would be much better off if it was really forthcoming about its business. While there are some executives that have appeared to have been truly kept in the dark on the company’s execution, it is the high-level people that know better that have been the most disappointing in their responses.
