1 GHz to 8 GHz 4×4 Full Fan-out Handover Test system supports 5G and WiFi 6E
In order to remain competitive and offer the latest in high-speed services, cellular hardware and Internet-of-Things (IoT) device manufacturers and system operators are moving to higher frequencies now available with Wi-Fi 6E (5.925 GHz to 7.125 GHz) and mid-band 5G (sub-6 GHz).
Moreover, these latest devices now operate in a wider variety of network topologies and modes than legacy systems, including mesh and heterogeneous cellular systems. This means that developing hardware/software and testing the latest wireless systems/devices require specifically designed test systems that have the frequency range, flexibility, and port count necessary to emulate a complex environment with a greater mix of device types.
Often with IoT, 5G, and Wi-Fi handover test systems, there isn’t a one-size-fits-all solution. In many cases, specific system requirements may need higher performance features, where other features are less critical. An example of this is a particular system needing higher levels of attenuation, but the step size may be lower resolution. Having customizable configuration options with a handover test system can be an enabling factor in the development of wireless network technology.
An Example of a 1000 to 8000 MHz 4×4 Full Fan-out Handover Test System
To accommodate the needs of 5G and Wi-Fi 6e wireless network hardware and system developers, JFW has recently released a 1 GHz to 8 GHz 4×4 Full Fan-out Handover Test system. This system is specifically designed to meet the performance requirements of the latest 5G sub-6 GHz and Wi-Fi 6e standards in a compact and standard 19 in rack mount unit. Once integrated into a lab, the handover system can be used to connect up to four mobile devices to as many as four network sources. Then, by manipulating the programmable attenuators between each point of connectivity, users can emulate real-world scenarios where radios are forced to choose between sources of varying RF signal strength. This unit can be controlled manually via the integrated front-panel control interface, with Ethernet, or using RS-232 serial communication. This unit allows users to write and execute complicated, scripted test routines to replicate specific RF environments encountered in the field and it makes for easy integration into API level test management software. Additional built-in functions like JFW’s Fade command simplify programming even more (Fade command automatically raises and/or lowers attenuation in regular intervals). The maximum attenuation per line is 95 dB with programmable attenuator step size of 1 dB. The connector types for this unit can be configured as either N-type or SMA female (50 Ohm).
