--  Memorandum of Understanding Lays Foundation for TD-LTE Roaming Between
      China and U.S.

  --  Companies Continue to Build on Strong TD-LTE Working Relationship 




HONG KONG and BELLEVUE, Wash., July 18, 2012 (GLOBE NEWSWIRE) -- China
Mobile International Limited, a subsidiary of China Mobile, the world's
largest mobile telecommunications company in terms of subscribers, and
Clearwire (Nasdaq:CLWR), a leading provider of wireless broadband
services, today announced that the two companies have signed a
non-binding memorandum of understanding (MOU) that lays the foundation
for international roaming between China and the United States using
TD-LTE.

Under the MOU, China Mobile International Limited and Clearwire plan to
collaborate on business and technical aspects of their respective
operations to define and institute the process necessary to support
international roaming and to ensure the operators' systems and devices
are able to support roaming. The companies also expect this agreement
to serve as a blueprint for future roaming agreements with other
members of the Global TD-LTE Initiative (GTI) of which China Mobile and
Clearwire are founding members.

"We recently demonstrated the roaming capability between Hong Kong FDD
LTE and Hang Zhou TD-LTE. With the commercial launches of TD-LTE
networks in major markets, these networks shall enable international
roaming to create a ubiquitous user experience and a unified market,"
said Dr. Tiger Lin, Chairman of China Mobile International. "Our goal
is to make a converged LTE TDD/FDD market in which our subscribers roam
between a TD-LTE network and a LTE FDD network at affordable cost and
enjoy the benefit of LTE service globally."

"Today's new agreement with China Mobile will add substantial momentum
to our own LTE network deployment and to the development of the TD-LTE
ecosystem around the world," said Dr. John Saw, Senior Vice President
and Chief Technology Officer for Clearwire. "The global nature of the
TD-LTE ecosystem and interoperability will be an important achievement
for both companies. We are pleased that our position as a leading 4G
operator has allowed us to develop a strong working relationship with a
key global counterpart like China Mobile."

China Mobile and Clearwire are developing TD-LTE networks in their
respective domestic markets. Through mutual collaboration, the
companies will provide their customers with 4G roaming capability and
help 4G services to follow the same global pattern towards
international accessibility as other wireless technology. The companies
expect the spectrum in the 2.3GHz to 2.7GHz range which will be used in
their TD-LTE network deployment will make up one of the most widely
deployed 4G configurations in the world.

Forward-Looking Statements

This release, and other written and oral statements made by Clearwire
from time to time, contain forward-looking statements which are based
on management's current expectations and beliefs, as well as on a
number of assumptions concerning future events made with information
that is currently available. Forward-looking statements may include,
without limitation, management's expectations regarding future
financial and operating performance and financial condition; proposed
transactions; network development and market launch plans; strategic
plans and objectives; industry conditions; the strength of the balance
sheet; and liquidity and financing needs. The words "will," "would,"
"may," "should," "estimate," "project," "forecast," "intend," "expect,"
"believe," "target," "designed," "plan" and similar expressions are
intended to identify forward-looking statements. Readers are cautioned
not to put undue reliance on such forward-looking statements, which are
not a guarantee of performance and are subject to a number of
uncertainties and other factors, many of which are outside of
Clearwire's control, which could cause actual results to differ
materially and adversely from such statements. Some factors that could
cause actual results to differ are:


  --  We have a history of operating losses and we expect to continue to
      realize significant net losses for the foreseeable future.
  --  If our business fails to perform as we expect or if we incur unforeseen
      expenses in the near term, we will require additional capital to fund
      our current business. Also, we will need substantial additional capital
      over the long-term. Such additional capital may not be available on
      acceptable terms or at all. If we fail to obtain additional capital, our
      business prospects, financial condition and results of operations will
      likely be materially and adversely affected, and we will be forced to
      consider all available alternatives.
  --  Our current plans and projections are based on a number of assumptions
      about our future performance, which may prove to be inaccurate, such as
      our ability to substantially expand our wholesale business and implement
      various cost savings initiatives.
  --  Our business has become increasingly dependent on our wholesale
      partners, and Sprint in particular. If we do not receive the amount of
      revenues we expect from existing wholesale partners or if we are unable
      to enter into new agreements with additional wholesale partners for new
      wholesale commitments, our business prospects, results of operations and
      financial condition could be adversely affected, or we could be forced
      to consider all available alternatives.
  --  We regularly evaluate our plans, and we may elect to pursue new or
      alternative strategies which we believe would be beneficial to our
      business, including among other things, expanding our network coverage
      to new markets, augmenting our network coverage in existing markets,
      changing our sales and marketing strategy and/or acquiring additional
      spectrum. Such modifications to our plans could significantly change our
      capital requirements.
  --  We plan to deploy LTE on our wireless broadband network, alongside
      mobile WiMAX and we will incur significant costs to deploy such
      technology. Additionally, LTE technology, or other alternative
      technologies that we may consider, may not perform as we expect on our
      network and deploying such technologies would result in additional risks
      to the company, including uncertainty regarding our ability to
      successfully add a new technology to our current network and to operate
      dual technology networks without disruptions to customer service, as
      well as our ability to generate new wholesale customers for the new
      network.
  --  We currently depend on our commercial partners to develop and deliver
      the equipment for our legacy and mobile WiMAX networks, and will be
      dependent on commercial partners to deliver equipment and devices for
      our planned LTE network as well.
  --  Many of our competitors for our retail business are better established
      and have significantly greater resources, and may subsidize their
      competitive offerings with other products and services.
  --  Our substantial indebtedness and restrictive debt covenants could limit
      our financing options and liquidity position and may limit our ability
      to grow our business.
  --  Sprint owns just less than a majority of our common shares, is our
      largest shareholder, and may have, or may develop in the future,
      interests that may diverge from other stockholders.
  --  Future sales of large blocks of our common stock may adversely impact
      our stock price.
