Ericsson and Polkomtel said they were successful with a test of LTE broadcast technology in Poland.

The trial was conducted on August 30, when the Polish operator streamed the opening game of the 2014 World Volleyball Championship between Poland and Serbia to 300 selected guests and journalists at Warsaw's National Stadium.

The test group was provided with 300 LTE broadcast-enabled mobile devices loaded with an application designed for the purpose.

With video traffic expected to grow by about 60 percent annually until the end of 2018, operators are under increasing pressure to enable their subscribers to enjoy a high-quality video experience anytime, anywhere, while still managing network efficiency and costs, Ericsson said.

The trial plays to the strengths of LTE, while avoiding the pitfalls. Carriers have nowhere near the spectrum or capacity to broadcast video over large areas, but the approach could be effective in a small defined space, such as a stadium.

The approach provides an alternative to Wi-Fi coverage, and so has the potential to become an important adjunct service for carriers.

With LTE broadcast, unique content can be delivered simultaneously to a virtually unlimited number of subscribers; for example, multiple video feeds showing different angles, close-ups or replays during live events, Ericsson noted.

Tobias Solorz, president of the management board of Polkomtel, said, " We are very pleased with the outcome and look forward to a thorough evaluation of the results. This successful test opens up the possibility of providing high-quality streams of sporting events and other programming to our subscribers, and we hope to offer this kind of service all over Poland in due course."

Polkomtel, who provides its services under the Plus brand, is one of the biggest telecommunication operators in Poland. The company serves over 13.5 million subscribers.

At present Polkomtel focuses mainly on promoting the use of mobile internet, including access based on LTE technology.
