A growing number of operators are studying and trialling the LTE Broadcast standard for mobile video delivery.

The latest market status report from the GSA confirms that at least 19 mobile network operators in Australia, China, France, Germany, India, Italy, the Netherlands, the Philippines, Poland, Portugal, Singapore, South Korea, UAE, the UK and the US, working with LTE systems providers and broadcast content owners, are deploying, trialling or studying LTE Broadcast technology.

LTE Broadcast is one of the key new features of 3GPP LTE Release 9 specifications known as evolved Multimedia Broadcast Multicast Service (eMBMS), which supports all specified bandwidths and formats of LTE, including FDD and TDD modes and LTE-Advanced carrier aggregation.

“GSA expects eMBMS support will be embedded in all smartphones in the coming years, and in any device containing LTE chipsets and modems such as connected cars, digital signage/billboards, etc.,” said Alan Hadden, president of the GSA.

Owing to the popularity of smartphones and tablets, mobile data traffic on networks is rapidly growing, driven mainly by video. In 2013 video accounted for about 40% of mobile data traffic, and various forecasts suggest a rise to 66-70% by 2017. By using LTE Broadcast enabled by eMBMS technology, operators can manage network assets more efficiently by multicasting popular content sought by multiple subscribers, e.g. live TV broadcasts, or tailored content for sporting events in stadiums or other venues. Operators can use off-peak capacity to deliver new service offerings, which could include rich media caching, or managed software updates including applications updates.

The first LTE Broadcast service was commercially launched by KT in South Korea in January 2014. inShare0
