LTE Broadcast Mobilizes at MWC

Posted by Sam Churchill on

Telstra and Verizon are preparing to test LTE Broadcast, which sends broadcast television signals over LTE networks. The Evolved Multimedia Broadcast Multicast Service is an LTE standard that uses existing cellular infrastructure, and radio frequencies, but broadcasts the same signal to any number of people.

LTE Broadcast allows the operator to shape its broadcast coverage area, covering either its entire footprint, or isolating a specific town, neighborhood, or even a specific venue – a stadium, for example.

Australia’s leading telecoms operator, Telstra, signed a deal that includes three trials to begin during 2013, with the two firms testing LTE-Advanced carrier aggregation, LTE het-net and an LTE broadcast solution.

Ericsson and Qualcomm are demonstrating an LTE Broadcast solution at MWC that relies on a set of new technology standards, starting with eMBMS, as well as new compression chips.

HEVC (High Efficiency Video Coding) promises to halve the bandwidth required to transport video content using H.265 compression. MPEG DASH (Dynamic Adaptive Streaming over HTTP (DASH), meanwhile, simplifies and standardizes the adaptive delivery of video to consumer devices, ensuring a better quality of service and greater efficiency.

Ericsson said TV and video traffic is set to dominate networks and grow from 40 percent to 90 percent of mobile traffic within the next four years.

Meanwhile, competitor Huawei, along with China Mobile and other partners demonstrated similar LTE Broadcast technology at Mobile World Congress. The companies displayed a range of LTE TDD terminals, including smartphones such as Huawei’s Ascend P2, data cards, MiFi, CPE and tablets, using HEVC (High Efficiency Video Coding), DASH (Dynamic Adaptive Streaming over HTTP) and eMBMS (Evolved Multimedia Broadcast/Multicast Service) technologies to support HD video.

Huawei and China Mobile’s joint demonstration of HEVC and eMBMS video services was the first time they’ve shown the LTE TDD video solution to the world.

HEVC using H.265 chips will make it possible to transfer 720p (1280×720 resolution) HD video at 1-2 Mbps, greatly improving the efficiency of multi-casting mobile data transmissions.

The BBC, the UK’s public-sector broadcaster, is working with Huawei on LTE Broadcast. The BBC wants to use LTE to repeat in permanent form the service it offered during the 2012 London Olympics, when it carried 24 simultaneous channels of competitions, according to Matthew Postgate, the broadcaster’s controller of research and development. LTE would be part of “a hybrid future” where the BBC expands the range of technologies that it uses to deliver programs to the public.

The BBC has experimented with mobile television before. In 2005 it worked with mobile operator O2 and transmitter operator Arqiva on a trial of mobile TV, delivering five public and private channels, using DVB-H, which transmitted mobile television broadcast TV frequencies. Like most other mobile TV trials, notably MediaFlo in the United States, it stumbled then fell flat on its face.

Dyle, which will deliver mobile television over broadcast television channels, uses the brain-dead ATSC-M/H standard in the United States. Like the defunct MediaFLO, it requires a special phone with a tv tuner. Resolution is low and range is limited. In contrast, LTE Broadcast works with smartphones on cellular channels. No tuner required.

Expway announced its eMBMS solution has been selected and is powering several trials in the US, Europe and Asia. Their solution is composed of Device Middleware, a DASH Video Player and a BM-SC Server. The solution integrates with operators existing OTT services as it relies on DASH video protocol.

Nokia Siemens Networks (NSN) introduced Liquid Applications, which turns the base station into an intelligent server to deliver local content to subscribers. NS wants to take advantage of knowing where and why people are using their smartphones and tablets. For example, augmented reality applications, or news and video content can be placed at the base station for instant local access to connected devices. SK Telecom will evaluate their Radio Applications Cloud Server.

NSN’s LTE Advanced network for Docomo will use remote radio heads, with baseband processing virtualized in the cloud, delivering 300Mbps.

Alcatel-Lucent’s TDD Metro Radio houses two of ALU’s lightRadio ‘cubes’ integrated with a directional antenna. China Mobile is deploying the 2.6 GHz TD-LTE Metro Radio in Shanghai, Nanjing and Qingdao with a variety of TD-LTE handsets providing access.

Clearwire’s LTE-Advanced network will leverage carrier aggregation to bond two 20 MHz channels into a fat 40 MHz pipe. That should deliver 500-600 Mbps, double the speed of a 20 MHz channel, when using 4×4 MIMO. No trenching. Not as dumb as TV.

Deliver 50 subs per sector with 10 Mbps each — or use LTE Broadcast to deliver 500 subs with 6 TV channels sharing one 10 Mbps stream. With behavioral targeting.
