Samsung's LTE technology for public safety

Samsung Electronics has demonstrated its public safety solution that uses LTE technology (PS-LTE) to support emergency services, based on the 3GPP Rel.12 standard.

The live demonstration, which was held last month at Samsung Electronics’ Digital City in South Korea, showed how the technology could be used during a real emergency situation by providing relevant parties with an optimal transmitting method, such as voice, multimedia push-to-talk (PTT) and videoconference services.

“The live demonstration of our PS-LTE solution is a significant achievement,” said Youngky Kim, president and head of networks business at Samsung Electronics.

“It takes us one step closer to successfully participating and building the world’s first nationwide public safety network with LTE technology, and we are confident in accomplishing this thanks to our leading product portfolio and constant innovation.”

Samsung’s eMBMS technology successfully connected more than 80 devices and simultaneously transmitted HD video during the demonstration.

eMBMS technology multicasts and broadcasts content to a large number of subscribers simultaneously without delays or disconnection. It can vastly improve the number of devices that can stream live video of the field.

With eMBMS there is also an opportunity to better utilise the available bandwidth, which is critical during massive disasters that require more than 1000 personnel for response, including firefighters, police and medical professionals.

As the leading contributor to the 3GPP PS-LTE standard, Samsung has supported the standardisation of the device-to-device (D2D) and Group Communication System Enabler for LTE (GCSE LTE) specifications in Release 12.

With the Release 13 specification, Samsung aims to further cement its leadership with public safety-related items such as mission-critical push-to-talk (MCPTT), Isolated E-UTRAN Operation for Public Safety (IOPS) and enhanced device-to-device (eD2D) standardisation.

Since February 2015, the company has also taken the role of vice chairman of SA6 (Service and System Aspect), which takes care of MCPTT standardisation.
