IPwireless explained that TDtv operates in the universal unpaired 3G spectrum bands that are available across Europe and Asia. According to the company, it allows UMTS operators to fully utilize their existing spectrum and base stations to offer subscribers attractive mobile TV and multimedia packages without impacting other voice and data 3G services.
A significant advantage of this new technology is its multicasting capability, meaning that any number of subscribers can watch a broadcast without any more bandwidth being used.
Alastair Brydon, CEO of Sound Partners, an analyst firm specializing in emerging technologies said, Most discussion of mobile broadcasting technology has revolved around broadcast networks, such as DVB-H, DMB and MediaFLO. However, these have a number of disadvantages for mobile operators, including lack of licensed spectrum, the massive cost of building a new network and a potential loss of control of mobile TV services to broadcasters. A 3G MBMS standards-based technology, such as TDtv, could provide the most attractive broadcasting solution for mobile operators.
IPWireless says operators globally have already committed to pilot the TDtv solution in the first half of 2006.
