OFDM NLOS to Dominate LTE Backhaul by 2018, According to ABI Research
AUSTIN, Texas --(Business Wire)--
Of all the available backhaul choices for LTE (News - Alert) macrocells and small cells
by 2018 sub 6GHz OFDM NLOS technology will become the most popular for
"last mile" backhaul. Fiber-based backhaul will be the second most
popular choice, where it is available, followed by millimeter wave and
the traditional LOS microwave links.
"The large change in backhaul type we see from 2013 to 2018 is due to
the very strong ramp of LTE small cells with the number of LTE small
cells deployed exceeding that of LTE macro eNodeB's in 2016 and reaching
more than 2X (News - Alert) the number of LTE macrocells by 2018," says Nick Marshall
principal analyst at ABI Research.
ABI Research's new report entitled "LTE Backhaul, Fronthaul, and
Flexihaul Considerations" discusses the impact on backhaul from LTE
networks and includes LTE evolution to LTE-A and LTE-B, SON,
synchronization, the X2 interface, and many other topics.
The influence of HetNets on backhaul is also discussed and thanks to the
increased scale of a small cell network with dozens or even hundreds of
sall cells deployed backhaul becomes essential to avoid or minimize
inter-cell interference and to avoid overburdening the macro network
with signaling or data traffic.
"We found that SON is a key enabler for a successful LTE deployment,
particularly when a small cell underlay is present, and that the
increasing sophistication of SON in the upcoming 3GPP releases places
strict latency and synchronization demands on backhaul," continues
The report also discusses fronthaul and describes the connections
transporting data from the base station at a cell site to an RRH in CRAN
