Axiom Test Equipment, an
electronic test equipment rental and sales company, has published a new blog post
entitled "Spectrum Analyzers Check 5G Occupied Bandwidth" that informs
people on how the right spectrum analyzers can help locate the interference of additional
signal energy that can interfere with 5G service. With a suitable spectrum analyzer,
occupied bandwidth measurements reveal the total integrated all signal energy within
the bandwidths that concern 5G system designers, service providers, and users and
when any interfering signals are at high enough power levels to be a concern.
Selecting a spectrum analyzer for occupied bandwidth testing is a matter of matching
the equipment’s capabilities to the limits of the OBW measurements. An analyzer’s
frequency range and amplitude range are good starting points for 5G OBW measurements,
especially due to the needs for such wide measurement bandwidth for 5G testing,
basically from almost DC through 60 GHz and higher. A suitable analyzer should offer
an amplitude measurement range that can survive the higher-power (more than 1 W
or +30 dBm) signals close to a 5G base station along with the sensitivity to detect
the low-power signals at the edge of a 5G base station’s coverage area.

Spectrum Analyzer by reading the full blog post on Axiom's website.
Spectrum Analyzers Check 5G Occupied
Bandwidth
Mobile wireless communications were once considered a luxury but is now more
than likely a necessity for many users requiring voice and data service. Cellular
wireless technology has quickly evolved from analog Advanced Mobile Phone Service
(AMPS) networks to digitally modulated Fifth Generation (5G) cellular wireless with
signals extending from the RF/microwave spectrum well into the millimeter-wave (mmWave)
frequency range from 24 GHz to above 60 GHz. Around the world, frequency channels
are reserved for 5G use, with the assumption that 5G signals will have those frequency
channels for exclusive use. When the channels are not exclusive, the additional
signal energy can cause interference that degrades or obstructs 5G service, resulting
in dropped calls and slow data rates. Fortunately, a spectrum analyzer can help
locate the interference, even at mmWave frequencies, by performing occupied bandwidth
(OBW) measurements.
Cellular telephone antenna towers attempt to provide uniform signal distribution
to a growing number of global users, with 5G networks faced with the challenge compared
to older generations of two different spectral regions: below 6 GHz and at mmWave
frequencies. Signal energy from the towers is directed towards the horizon with
some downward scatter and signal absorption making uniform signal distribution around
the cell site difficult. The higher-frequency mmWave signals, with their short wavelengths,
have much shorter propagation distances than the longer-wavelength, lower-frequency
signals, requiring many additional smaller 5G base stations for effective mmWave
frequency coverage.
Advanced antenna technologies, such as the use of active phased-array antennas
like those used in military radar systems, generate directional signal beams that
can be actively steered to users but 5G networks, with their ever-increasing numbers
of users, require dense signal environments across wide signal spectrums. And interference
can prevent reliable signal reception from a 5G base station. With a suitable spectrum
analyzer, OBW measurements reveal the total integrated all signal energy within
the bandwidths that concern 5G system designers, service providers, and users and
when any interfering signals are at high enough power levels to be a concern.
