LTE bandwidth optimizationFor delivering more comprehensive user experience, we offer you a LTE broadcasting or Evolved Multimedia Broadcast Multicast Service (eMBMS) service
Nowadays LTE got widespread among mobile operators as it delivers higher bandwidth with the lowest amount of spectral resources, delivers better user experience and allows to offer services to end users with lower costs. Evolved Multimedia Broadcast Multicast Service (eMBMS) or LTE broadcasting provides LTE service providers with an opportunity to cut costs per bit and deliver content to multiple users in just once.
What is multicast? Multicast vs unicast
Multicast is a group communication where content is delivered simultaneously to a group of users. Multicast provides an alternative for distributing content to meet “clustered” demand, for example, distributing local regional live events. Therefore, the multicast deployment decision can be assessed by market and by region. This “one-to-many” distribution mode is a valuable alternative to unicast (one sender, one receiver) when a large number of users are interested in the same content. One of the advantages of multicast is that LTE resources, reserved for eMBMS, are only used when needed, thus, creating absolutely no impact on LTE unicast capacity at other times.
When is multicast used?
The most common uses for multicast include distributing video, music, software, news, weather, ads and other data to a mass audience. The content can be live or preloaded for later usage, which has the potential for additional cost savings. Many mobile service providers are applying eMBMS solutions for live streaming, as eMBMS sessions can be set up dynamically and resources can be shared efficiently with unicast sessions.
Example of multicast employment.
Let’s take an example. During live streaming of major sports or news events, unicast must send the same video to every user individually. But multicast takes advantage of the inherent broadcast qualities of wireless networks to send the video only once to reach an equal number of end users. Thus, by using eMBMS the cost per Mb could be significantly reduced. Besides, less equipment will be required to operate the network for the same number of megabits delivered.
