Vodafone, Telefonica, Orange, and 3UK Report Successful Results from TDtv Trial with IPWireless and MobiTV

Vodafone, Telefonica, Orange, and 3UK today announced the results
of their successful joint technical trial of TDtv. TDtv is the UMTS
TD-CDMA-3GPP Multimedia Broadcast and Multicast Services (MBMS)
standard for mobile television solutions. The trial provided valuable
insights into the technology's capability and successfully
demonstrated how existing spectrum can be used to deliver mobile
television and other multimedia services.

The participants are now discussing next steps and exploring how
the findings from the trial could be used to develop commercial
models.

Key Trial Results

-- Reliable delivery of mobile TV services using TDtv technically
viable

-- Up to 11 to 14 high quality channels can be delivered in 5MHz
of TDD spectrum

-- Coverage comparable to WCDMA but using fewer cell sites

-- Performance consistent when moving at speed

-- Dual mode handset viable

The TDtv trial, announced in October 2006, aspired to test key
performance and deployment aspects of the mobile TV technology.
Covering a large area of Bristol in the UK using only 12 macro-cell
sites, the trial proved that the technology has the ability to offer
reliable television delivery at the data rates that are needed to
provide high quality mobile TV services.

The trial showed that eleven high quality channels could be
delivered across the service area, with the potential to deliver up to
fourteen channels with planned future technology developments.
Significant coverage gains were demonstrated when using key TDtv
performance enhancement technologies including macro site combining
and receive diversity in the user device. The gains from these
technologies demonstrated in the trial indicate that TDtv may be able
to provide the same coverage as WCDMA when deployed on 35% of the
WCDMA sites.

TDtv also proved its ability to perform at motorway speeds during
the trial, allowing it to address a wide range of use cases such as
when travelling on a train.

Initial coexistence testing to explore the simultaneous operation
of 3G FDD and TDD also proved the theoretical viability of a dual mode
WCDMA/TDtv handset.

Finally, the TDtv network also proved very reliable with 99.999%
availability during the trial.

Professor Michael Walker, Director of Research and Development at
Vodafone said: "Trials are an extremely important part of our
strategic product development and help us build a comprehensive
understanding of how the technologies work and the customer experience
they will offer. The outcome of this trial will help us evaluate the
commercial potential of TDtv as part of the MBMS assessments we are
undertaking."

"The TDtv trial in Bristol has proven the ability to effectively
use our unused TDD spectrum for a wide variety of Mobile Broadcast
Services and the potential of a SFN deployment to support impressive
coverage gains," said Cayetano Lluch Mesquida, Managing Director,
Technology and Services, Telefonica Moviles Espana. " Nevertheless, we
would like to see the next steps taken to ensure a wide variety of
terminals and interoperable services are available for the platform."

Vivek Badrinath, Executive Vice President, IT Networks and Product
Support, Orange said: "We are committed to fuelling the growth of
mobile TV by ensuring our customers are offered the best quality and
content now and in the future. The TDtv trial forms an important part
of our research into potential technology solutions for the future,
equally important is the collaboration of other industry players, who
are now working together to learn and build from our shared
experiences."

David Cooper, 3UK CTO said: "3 is pleased to support this
initiative. The results of this first trial demonstrate TDtv has the
potential to deliver a mass market Mobile TV solution. As the first
network to launch 3G services in Europe, we're always looking at ways
to develop the service we offer customers."

About TDTV

TDtv is the 3GPP MBMS solution that operates in the universal
unpaired 3G spectrum bands that are available across Europe and Asia
at 1900MHz and 2010MHz. It allows UMTS operators to further utilise
their existing spectrum to offer subscribers attractive mobile TV and
multimedia packages without impacting other voice and data 3G
services, which use the universal paired 3G spectrum. The technology
also allows mobile operators to use network sharing to significantly
reduce Capex and further improve the business case for mobile TV.

TDtv enables mobile operators to deliver multiple TV channels to
an unlimited number of concurrent customers. Mobile operators
deploying TDtv would also be able to deliver digital audio, multicast,
or other IP data cast services to enhance their service offerings to
customers.

About the trial

TDtv base stations provided by IPWireless were deployed to deliver
broadcast services to TDtv enabled smart phones. MobiTV, Inc., the
international mobile and broadband television services company,
provided the client application, as well as facilitated the mobile
content and media delivery components of the trial. Roke Manor
Research, a trusted and capable independent technology assessor for
the mobile industry developed and implemented the test plan and
published results for the trial.

Because TDtv is based on the 3GPP family of standards, integration
of TDtv with WCDMA on both the network and device side is simplified.
Jointly testing TDtv allowed the operators to assess the coexistence
of TDtv channels with neighbouring TD-CDMA and WCDMA networks.

About IPWireless
