3UK, Orange, o2 owned by Telefonica, and Vodafone today announce the launch of a technical trial of TDtv, the UMTS TD-CDMA-3GPP Multimedia Broadcast and Multicast Services (MBMS) standard-based solution.
The trial is expected to provide valuable insights for mobile operators into the potential of using their existing spectrum and infrastructure to deliver mobile television and other multimedia services.
The TDtv trial, which is scheduled to run to the end of the year, will test key performance and deployment aspects of the mobile TV technology.
TDtv base stations provided by IPWireless have been deployed on 12 cell sites covering parts of Bristol in the UK to provide broadcast services to TDtv enabled smart phones.
MobiTV, Inc., the international mobile and broadband television services company, will provide the client application, as well as facilitate the mobile content and operational components of the trial.
TDtv 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 utilize their existing spectrum and network infrastructure to offer subscribers attractive mobile TV and multimedia packages without impacting other voice and data 3G services.
TDtv enables mobile operators to deliver multiple TV channels to an unlimited number of 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.
As 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 will allow the operators to assess the coexistence of TDtv channels with neighbouring TD-CDMA and WCDMA networks.
