Motorola Demonstrates World's First WiMAX 802.16e Mobile Handoffs in Downtown Chicago


Achieves milestone demonstrating live, contiguous service between WiMAX cells; shows voice, data and multimedia applications on pre-commercial Sprint Xohm(TM) network

CHICAGO, Sept. 26 / / -- WiMAX World USA -- Motorola
(NYSE: MOT) presented a mobile WiMAX experience last night that included live
handoffs during an exclusive cruise along the Chicago River for media and
industry analysts in town to attend WiMAX World USA. Attendees experienced
uninterrupted mobile applications including web browsing, Voice over IP (VoIP)
calls, video streaming and MobiTV while moving past access point sites along
the route of the cruise.

In addition to the cruise, Motorola has successfully demonstrated several
of these applications on streets along the Chicago River while driving at
speeds beyond 50 mph and while riding Chicago's famed elevated train. These
demonstrations are another step in achieving an all IP wireless mobile network
that is capable of supporting VoIP, data and video.

"Motorola has reached a significant milestone in the industry by proving
through these demonstrations that mobile WiMAX is real and ready for
commercial deployment," said Fred Wright, Motorola senior vice president, Home
& Networks Mobility. "We tackled one of the most challenging environments --
a river lined with tall buildings, 30 feet below street level, and crossed by
numerous steel bridges -- to bring this WiMAX experience to life."

"Motorola has made tremendous progress in the deployment of our Xohm WiMAX
network in Chicago. This live demonstration provided just a glimpse of what
WiMAX technology can deliver," said Barry West, Sprint Nextel CTO and
president, Xohm Business Unit. "We are on schedule to begin Xohm
pre-commercial service in Chicago by the end of 2007, with commercial service
planned in that and other markets beginning April 2008."

Motorola, a market-leading provider of end-to-end WiMAX solutions with
40 WiMAX trial deployments with customers around the world and contracts with
12 of them for commercial WiMAX systems, showcased its latest high mobility
software on Sprint's pre-commercial Xohm network. The array of devices used
during the outing included Motorola's trial WiMAX mobile handset developed for
high speed video telephony and laptops enabled with Motorola's WiMAX PC cards.
The network infrastructure used for this demonstration was standard Motorola
WAP 25400 access points with backhaul provided by Motorola's wireless IP
backhaul equipment to its Innovation Center in Schaumburg, Ill., where a
Motorola IMS provided connection to the public switched telephone network.

"Motorola continues to drive market acceptance of WiMAX technology by
delivering products and deploying networks that meet the diverse needs of many
types of operators worldwide," said Phil Marshall, vice president of Yankee
Group's Enabling Technology and Asia-Pacific Research and Consulting
practices, who was also on the cruise. "From the nationwide 802-16e network
it deployed in Pakistan to connect the previously unconnected, to the network
it is building for Sprint to deliver a whole new mobile internet experience,
Motorola has proven itself to be a leading supplier of end-to-end WiMAX
solutions."

The Chicago market is one of six in the U.S. that Sprint (NYSE: S) has
awarded to Motorola to build WiMAX network infrastructure to support its
recently announced Xohm mobile Internet services.

With Xohm mobile Internet, customers will be able to experience a new form
of interactive communications, high-speed Internet browsing, local and
location-centric services, and multimedia services including music, video, TV
and on-demand products. Sprint also plans to bring Xohm WiMAX mobile Internet
customers search, interactive communications and social networking tools
through a new mobile portal in a deal announced with Google.

WiMAX technology is changing the way the telecommunications industry is
looking to connect people to people, and to the information and entertainment
they want on-the-go. WiMAX technology will allow consumers, businesses and
government to experience a data network that offers faster speeds, greater
convenience and enhanced multimedia quality. WiMAX also makes broadband
accessible in all regions of the world for fixed, portable and mobile users
with the most cost-effective, fastest and easiest-to-deploy option in the
market today, often providing an economical way to provide telecom service
where previously there was none.

The WAP 25400 is part of Motorola's WAP 400 series which features
diversity antenna techniques and provides Non-Line-of-Sight, fixed and mobile
wireless broadband connections. These access points are based on the IEEE
802.16e-2005 technology standard and include spectrally efficient S-OFDMA
interface, low latency performance, and IP based architecture.

Enhanced system gain, supported by diversity MIMO antenna capabilities,
allows strong indoor penetration as well as support for cellular-like mobility
applications. Additionally, QoS capabilities, security features, and
redundancy options make the WAP 400 series platform a true carrier-class
solution. The WAP 400 series access points, paired with a common IP core,
will support seamless inter-technology handovers.
