The AWT Global founded
by AceWavetech has launched a new Passive Inter-modulation (PIM) analyzer for Terrestrial
Trunked Radio (TETRA) and Ultra-High Frequency (UHF) tagged S1L TETRA MK2 Series, reports ITRealms.
TETRA, formerly known as
Trans-European Trunked Radio is a professional mobile radio and two-way
transceiver, popularly known as a walkie talkie.
ITRealms gathered that
TETRA was specifically designed for use by government agencies, emergency
services namely the police forces, fire departments, ambulance; for public
safety networks, rail transportation staff for train radios, transport services
and the military.
While the UHF is a designate of the International
Telecommunication Union (ITU) radio frequency range of electromagnetic waves between
300 Mega Hertz (MHz) and 3 Gega Hertz (GHz).
President, AWT, Mr.
Wolfgang Damm disclosed to ITRealms that the new PIM analyzers were designed
for measuring TETRA and UHF networks in the 400 MHz frequency range.
“They come with a wide
variety of test modes for different tasks including, field measurement mode,
analyzer, multi PIM display, Rx sweep, PIM vs. time and single carrier mode for
insertion loss (IL) and coverage measurements,” he said.
On the Distance-to-PIM
option, he said, it has been embedded in the system, reconnecting antennas is
not required, although lower frequencies have higher wavelengths, which demand
larger sized components.
According to him, AWT’s
engineers have managed to embed the complete system, including options into a
compact and convenient single-body enclosure.
“TETRA or Terrestrial
Trunked RAdio is used globally by many public safety organizations, such as
police, fire departments, border patrol, cost guard and many more. It is
mandatory that these networks work perfectly. The issue is here not just about
a nuisance with low data transfer or dropped calls. Problematic emergency
networks may cause people getting hurt and even lives are at stake,” Damm said,
stressing that TETRA utilizes
sophisticated modulation schemes, thereby increasing data transmission rates,
but this makes it unfortunately also more suceptibility to interferences.
Aa
said by him, TETRA channel frequency configuration may cause cross band
intermodulation problems, yet both issues make the PIM testing of networks
paramount.
