Optimize your 4G/5G network with Multicast

Elevating Connectivity: Unleashing the Power of Multicast in 4G/5G Networks for Critical Communications

In the dynamic realm of critical communications, the ability to disseminate information swiftly and efficiently is non-negotiable. Multicast technology, with its ability to transmit data simultaneously to multiple recipients, offers a paradigm shift in network optimization. This approach not only conserves bandwidth but also ensures that vital information reaches its intended audience with minimal latency, a crucial factor in mission-critical scenarios.

What is eMBMS ?

eMBMS stands for evolved Multimedia Broadcast and Multicast Services. It provides multimedia services over LTE network in Broadcast mode. It is also referenced as LTE-B or LTE-Broadcast.
This technology is notably standardized by 3GPP and has been introduced firstly in Release 6 with MBMS, to enable multicast (or broadcasting) of multimedia content over 3G UMTS Radio Access Network.
It is then in release 9 that the eMBMS has been introduced, to improve coverage and efficiency notably with flexible allocation of resources in LTE.

eMBMS is a powerful technology for efficient delivery of broadcast & multicast services where data is sent only once to all devices. It is notably relevant when the same content is consumed by several receivers in the same area (> 1.5 devices per cell). eMBMS can notably be used for various use cases:

• Mission Critical and Public Safety
• Infotainment, Live TV Entertainement
• HD Map Updates, Firmware Updates, Traffic Information
• Amber alerts, Emergency Alerts, Industry 4.0

eMBMS relies on Multicast, which offers a substantial gain in radio capacity when compared to Unicast. When several users require the same content, at the same time, in the same cell. Network resources are used more efficiently and network capacity is freed up.
