Ethernet exchange operator CENX is to provide a 4G LTE wireless backhaul platform to support LightSquared’s deployment of a 4G LTE wireless broadband network across the US.
CENX hopes its OSS
platform will support LightSquareds bandwidth
requirements helping to drive the lowest cost per bit and
leading to higher profitability.
Ethernet backhaul can
integrate multiple access providers across a region, offer a
path to a multi-class of service and support systems for
monitoring backhaul and SLAs that are Ethernet ready. As well
as offering operational simplicity, CENX claims 4G LTE backhaul
will deliver savings of up to 30%.
CENX president Nan Chen
described this as a very significant move for the
company: Ethernet expertise is paramount to delivering
efficient backhaul and integrating all the access providers
together, he said.
This really builds
on the exchange platform we already have. As a nationwide
operator, LightSquared will be a big proving point for us to
really deliver our values to the wireless
CENX has been engaged in
discussions with LightSquared for a year and is now in the
process of executing the move.
The agreement with CENX is
likely to help Lightsquared with its ambitious plans to
construct a 4G LTE network that will provide coverage to 92% of
the US by 2015. The network hopes to combine satellite
technology and a ground-based wireless communications network,
both using the same 1.5 to 1.6GHz L-band radio spectrum, with
the aim of providing terrestrial wireless coverage to at least
100 million people by the end of 2012, to 145 million people by
the end of 2013, and to 260 million people by the end of
Our decision to work
with CENX was based on their unparalleled expertise in Carrier
Ethernet and its exchange services, said LightSquared
chief network officer Doug Smith.
A regulatory battle
between LightSquared and the Global Positioning System (GPS)
industry is, however, ongoing. The L-band spectrum it proposes
to use for LTE is immediately adjacent to the 1559-1610MHz
spectrum band used for the signals between GPS satellites and
GPS receivers, which include aviation, cellular, general
location and navigation, high precision, networks, space-based
receivers and GPS timing receivers. There was concern that
high-powered signals from LightSquareds ground-based
transmitters would overpower the comparatively weak GPS signal
from space. For a full depth analysis click
