SATIMO Innovates With MIMO Test Systems!

PARIS, May 10, 2010 - SATIMO launches new systems that offer laboratories effective
solutions to test the influence of Multiple Input/ Multiple Output (MIMO)
signals on the performance of wireless devices. MIMO device testing has
become necessary due to the increasing use of multiple antennas in single
pieces of equipment.

The Telecom sector has been rapidly evolving toward the "4G"
(WiMAX, LTE) which provides more functions and improved connectivity for
wireless network and devices. To secure the connection and ensure higher
rates, manufacturers in the Telecom sector now use MIMO technology. This
technology is based on the integration of several antennas in an emitter
(base station) or receiver (wireless communication device). Laboratory
testing of this technology raises complex challenges.

In a real environment, either indoor or outdoor, a signal
emitted by an antenna reflects off surrounding obstacles to form several
signals. To measure the performance of a MIMO antenna system, the various
environmental influences on a signal must be taken into account by modeling
the direct signals, reflected signals (multipath), and any interfering
signals (coming from competing emitters). A MIMO system must therefore
simulate different electromagnetic environments in order to evaluate and
optimize the performance of mobile devices in real operational conditions.

With over 10 years of experience in multi-probe technology,
SATIMO has developed a family of MIMO test systems that best answers these
technical requirements. The uniqueness of the systems is based on the use of
an arch that integrates many probes and an instantaneous calibration unit to
speed up the measurement time. Both easy to use and extremely fast, these
systems perfectly answer industrial expectations. With these new systems,
SATIMO, already a leader in the antenna measurement market, strengthens its
position in the Telecom sector.
