Research and Markets: Signals Ahead: eMBMS / LTE Broadcast - Once Bitten, Twice Shy?
DUBLIN --(Business Wire)--
Research and Markets (http://www.researchandmarkets.com/research/dr8srm/signals_ahead)
has announced the addition of the "Signals
Ahead: eMBMS / LTE Broadcast - once bitten, twice shy?" report
to their offering.
In 2007 we identified a staggering seventeen different technologies that
enabled "mobile TV". Fast forward to 2014 and virtually all of these
technologies have fallen by the wayside, including two different
implementations of MBMS, FLO and DVB-H. In this context, it is no
surprise that the industry frequently uses the term LTE (News - Alert) Broadcast to
refer to an enhanced version of MBMS (eMBMS) that is a part of the LTE
standard. Release 8 introduced the MBSFN subframe but the real meat of
the feature gets introduced in subsequent releases.
For multiple reasons, we believe that things will be different the
second time around. First, eMBMS/ LTE Broadcast has universal support
throughout the industry. Multiple chipset companies are enabling the
middleware and making other necessary changes to their chipsets. All
infrastructure vendors support it, albeit with a couple of different
architectures. Major operators are also deploying the feature and/or
doing announced or unannounced trials. In 2014 we believe that 3
operators will launch commercial LTE Broadcast services and we are aware
of an additional 8 operators that have plans o trial or are currently
The "e" in eMBMS may be lower case, but it is large in stature. In
addition to riding on the coattails of a more spectral efficient air
interface, LTE Broadcast leverages a Single Frequency Network (SFN),
which turns what would otherwise be unwanted interference into a desired
signal. The net result is tremendous gains in spectral efficiency with
only modest areas where coverage holes could exist - something that
unicast could potentially fill. In fact, the network economics for LTE
Broadcast can be more favorable than unicast with as few as one or two
active mobile devices per sector (the exact answer is based on the cell
site density and other factors).
Specific topics include the following:
- What went wrong the first time? In 2007 there were 17 "mobile TV"
technologies and virtually all of them, including MBMS FDD and MBMS TDD,
failed to deliver. That was then, this is now.
- Technical Primer. We provide a tutorial on how eMBMS impacts the LTE
network architecture and how the MBSFN subframe is able to deliver the
same multicast content to all users with higher spectral efficiency and
coverage than good old LTE.
- Tracking the Release functionality. We discuss the features of LTE
Broadcast, including some futuristic features, and when they get
introduced into the standard.
- The Use Cases. The Use Cases for LTE Broadcast are fairly well
understood. We review them but focus on the Use Cases that we really
like as well as those Use Cases that are questionable. Bottom line, LTE
Broadcast rollouts will be very gradual and the Use Cases, including the
size of MBSFN areas, will expand very gradually over time.
- The Challenges. LTE Broadcast does come with its own set of
challenges, although many of the challenges can actually be viewed in a
positive manner. First and foremost, launching LTE Broadcast isn't
nearly as simple as upgrading the network and flipping a switch.
Further, it does very little to address the data tsunami, in particular
in the near term.
- Market Outlook. We provide our near-term outlook for LTE Broadcast and
the catalysts that could drive wider spread adoption - including more
operators larger / more frequent MBSFN Areas.
