What is CERNO 4.0?
Cerno is a radio frequency (RF) testing and data collection platform engineered to capture various RF data parameters essential for the operation of mobile devices such as handsets and tablets. Its uniquely compact and lightweight design ensures ease of use, allowing anyone to perform measurements on cellular and Wi-Fi networks without extensive training or cumbersome equipment.
The latest generation, CERNO 4.0, was created to further streamline, accelerate, and enhance the testing processes for 2G to 5G cellular technologies.
CERNO 4.0 comprises 2 primary components:
CERNO Controller: The central processing unit or ‘brain’ of the system, essential for every Cerno 4.0 setup. Includes device storage for maps, floorplans, and firmware.
CERNO Module: Contains six Handset Equivalent Modules (HEMs) equipped with radio transceivers, antennas, and processors. Each HEM accurately measures power (RSRP/RSCP/RSSI), noise (SINR/RSRQ/ECNO), as well as many other relevant RF metrics across various technologies and bands. A minimum of one CERNO Module is required, with the option to cascade multiple modules for expanded capabilities.
CERNO 4.0 can be used in 2 ways:
Walk Testing
Walk Testing
A Test Engineer carries the Cerno 4.0 and walks through a site, allowing the device to automatically measure RF signal strength and noise. All the engineer needs to do is upload a floorplan to the tablet provided and mark their location on it at regular intervals. The Cerno is best suited to be used in the Ranlytics backpack to ensure body loss is minimised and the kit is fastened securely.
Drive Testing
Drive Testing
A Test Engineer places the Cerno 4.0 in a vehicle and drives a test area. The device automatically plots a continuous location without user input using GPS. This method can also be used when walk testing if outdoors.
