CellWireless: New Generation Scanner and Spectrum Analyzer
With Celplan's powerful CellWireless™ solution you get three functions in one device: Technology Scanner, Spectrum Analyzer and I/Q Digitizer.
CellWireless™ is comprised of the CellDigitizer™ hardware and the CellScanner™ and CellSpectrum™ software.
Need 5G NR drive test measurements? We've got you covered!
The hardware: CellDigitizer
Celplan’s CellDigitizer is a versatile Software-Defined Radio Receiver that samples and digitizes up to 125 MHz of spectrum at a time, from 9 kHz to 40 GHz.
The same device can be configured as a GSM, UMTS, LTE and 5G NR signal scanner, as a spectrum analyzer or an I/Q Digitizer.
The software: CellScanner and CellSpectrum
With CellScanner, RF engineers can easily perform drive tests to collect and analyze signal measurements from 5G NR, LTE, UMTS and GSM cells on air, which is a key part of the RF optimization process.
Cellspectrum, on the other hand, allows operators to observe the radio environment. Extremely useful to perform spectrum clearance or to find nasty external interference.
Celplan’s software allows to collect data in multiple formats, compatible with today’s postprocessing tools: TEMS Discovery, Nemo Analyze, Windcatcher, Gladiator and others!
Do we really need a scanner?
If test UEs allow to perform drive test measurements of signal strength and signal-to-noise ratio, then why should we use a scanner?
The answer is that commercial mobile terminals have limitations in assessing RF conditions.
On the other hand, scanners such as CellDigitizer are designed specifically for RF measurements, providing information that exceeds the capabilities of commercial mobiles
Measures all selected channels (frequencies)
Measures the channel where the mobile is camped or connected. It only measures different frequencies under certain conditions and does not do so continuously.
High dynamic range. Presence of dominant cells does not affect the ability to detect weak cells.
Lower dynamic range.
Typical precision of ± 1 dB
Typical precision of ± 4.5 dB (± 9dB in “extreme conditions”)
High measurement speed (> 40 channels/second).
Lower measurement speed.
Measurements are network independent.
Measurements depend on network configuration. Logical parameters not configured correctly can prevent measuring cells that are actually on service.
