Motorola Participating In 25 WiMAX Trials, Nine WiMAX Network Deployments Worldwide


Latest trial with TVA in Brazil to test mobile WiMAX technology in Rio de
Janeiro

ORLANDO, Fla., March 27 // -- CTIA Wireless 2007 --
Motorola (NYSE: MOT) announced today it has nine contracts for the
installation of 802.16e WiMAX networks and is taking part in 25 trials with
the technology worldwide, confirming the growth of WiMAX especially in
emerging markets. Motorola now has WiMAX trials and deployments underway in
six continents.

The newest Motorola WiMAX trial agreement is with TVA, a multi-services
operator in Brazil, which will conduct a trial for the use of mobile WiMAX
technology (802.16e) in Rio de Janeiro. The solution will cover central Rio
and part of the south of the city, providing wireless broadband services with
voice, data and multimedia capacity for a select group of users.

The WiMAX platform, including use of the 2.5 GHz spectrum in line with
Anatel regulations, enables rapid digital inclusion, as well as an opportunity
to provide multimedia (voice, data and image) services. By digitalizing its
MMDS (Multipoint Multichannel Distribution System) network, TVA is able to
expand its service offering, creating a new model for competition.

In the agreement, Motorola will supply its wi4 WiMAX access points and end
user equipment. WiMAX 802.16e permits indoor installation of customer
premises equipment without line of sight to the radio base stations, ensuring
high user service capacity. The technology also permits high data rates and a
wider range of coverage than other currently available technologies.

The trial period will enable TVA to assess the performance of the
technology in the differentiated demographic topology of the city of Rio de
Janeiro, as well as the mobile TV, video, VoIP, and media streaming services
and data applications.

"The digitalization of our MMDS network maximizes spectrum use, enabling
us to offer our subscribers more services and products," said Virgilio Amaral,
director of strategy and technology of TVA. "Additionally, we intend to
extend our TVA at School social project, one of the targets of which is to
provide broadband access, cable TV and content for public schools."

"We are very pleased to announce this WiMAX trial in Latin America,
particularly because it is being executed in conjunction with a company
recognized for innovation in providing broadband services in Brazil," said
Eduardo Stefano, vice president, sales and service, Motorola Networks &
Enterprise. "Motorola is a leader in mobile WiMAX solutions worldwide and is
committed to delivering state-of-the-art technological services and solutions
to its customers."

"Our solution is flexible, easy to install, scalable and very competitive
compared with the fixed offerings currently available on the market, such as
ADSL and cable," Stefano added.

Motorola's WiMAX solutions support long-range, personal broadband through
fixed, portable, nomadic and mobile applications. The company's MOTOwi4(TM)
portfolio of WiMAX solutions consists of access points (radio base stations);
customer premises equipment (CPE); PC WiMAX cards; and, mobile WiMAX chipsets,
which are currently under development and will be used in Motorola devices to
complete broadband wireless networks. To get more information about Motorola
