Barcelona, Spain - 15 February
2010 - At Mobile World Congress in Barcelona this week Deltenna
CEO, Andrew Fox, discussed how the company's Frequency Re-bander
products were an essential component of main operators' LTE trials.
Most LTE test mobiles use the popular UMTS Band 1, but operators in
different countries have spectrum allocations in a large variety of
different bands. For example, US operators are deploying in the 700
MHz bands (Bands 13 and 14), and there is very limited availability
of mobiles and other test equipment at these
frequencies.
The Deltenna Frequency Re-bander
enables the testing of base station equipment operating in bands
other than UMTS Band I by re-banding the 1920-1980MHz uplink (UL)
and 2110-2170MHz downlink (DL) to another operating band.
A fully duplexed UL/DL path allows
interfacing directly to the primary antenna port of a widely
available Band I test mobile or TEMS™. A second DL path allows
testing of DL MIMO.
"We originally identified this
market need two years ago", said Deltenna CEO Andrew Fox, "and we
developed our flexible Re-bander products to address this". The
Re-banders have a low noise figure and are very linear, which
together with their high stability crystal references means that
they can be used reliably in many test applications, as well as for
field trials. "Sales or the Re-banders have really taken off over
the last few months", said Fox. "We're shipping them as fast as we
can make them".
Deltenna Frequency Re-banders are
available with uplink outputs in bands 2 to 14 and at 8.3" x 8.0" x
1.75" (1U) are a conveniently portable size.
