World´s first microwave connection between LTE main and remote radio units

* Ericsson performs demonstration of microwave connection between LTE main and
remote radio units for the first time
* Alternative for situations in which use of optical fiber is not ideal, can
be used to add small cells to existing networks, thereby creating
heterogeneous networks (hetnet)
* Innovative solution provided microwave capacity of 2.5Gbps

Until now, operators have been restricted to using optical fiber to connect main
and remote radio units (RRUs) in their networks. However, there are situations -
such as in dense urban environments - when using fiber for this purpose can be
difficult, costly and limiting. Ericsson (NASDAQ: ERIC) has now successfully
demonstrated that it is possible to connect the main and remote radio units with
a microwave link, thereby offering operators greater flexibility.

In the tests, conducted at the Ericsson premises in China, the microwave
connection between the main unit and the remote unit was provided by a MINI-LINK
PT, working in the E-band (70-80GHz). The microwave link provided capacity of
2.5Gbps, which is sufficient for a wireless main-remote system in compliance
with Common Public Radio Interface (CPRI) standards. This is one example of new
applications with high-capacity packet microwave products.

Since the MINI-LINK PT is compact and easy to install outdoors, this solution
will allow for rapid connection of RRUs - including small RRUs that can be used
to add small cells to existing networks, thereby transforming them into
heterogeneous networks (hetnets) and boosting overall capacity.

Ola Gustavsson, Head of Product Line Microwave and Mobile Backhaul at Ericsson,
says: "In situations where optical fiber isn´t the best option due to cost or
time to market, it is great that we now have an alternative - in the form of
microwave - that will allow operators to connect the main and remote radio units
in their networks. Making it easier for operators to do business is our primary
business.
