Obama Pushes Expanding High - Speed Wireless
Service
President Barack Obama on Tuesday called for expanding highspeed wireless services to meet the voracious appetite of
consumers and businesses, a task that could be tough because
airwaves are a finite resource and demand is almost limitless.
"Within the next five years, we will make it possible for business to
deploy the next generation of high-speed wireless coverage to
98% of all Americans," Obama said during his annual State of the
Union speech to the U.S. Congress.

Google awards $100 million to Eric Schmidt
Google Inc. has awarded $100 million worth of equity to Eric
Schmidt, who is stepping aside as CEO but will stay with the
company as executive chairman.
Google said in a regulatory filing on Monday the stock and stock
options will be granted on Feb. 2 and will vest over four years.
The magnitude of the award is "unusual" for an executive who is
transitioning out of the CEO role

Google plans biggest hiring year in company
history
Google is about to go on a hiring binge.
The company said Tuesday that it plans to recruit a record number
of new employees in 2011, as it pushes forward with an
increasingly diverse product portfolio.
Google said in a blog post that it expects to exceed its 2007 hiring
record, when the company added more than 6,000 people to its
ranks. Last year, Google (GOOG, Fortune 500) grew by about
4,500 employees, which was its second-largest year for
headcount growth.

Google makes waves and may have solved
the data center conundrum
Google is pondering a floating data center that could
be powered and cooled by the ocean. These offshore
data centers could sit 3 to 7 miles offshore and reside
in about 50 to 70 meters of water.
