The Wi-Fi 6E Multipath Emulator from Spectrum Control is an Integrated Programmable Subsystem to test the functionality of Wi-Fi devices in a true multipath environment. It is ideal for MU-MIMO conductive testing, which is cost-effective and offers a controlled and highly repeatable test environment. The emulator aims to ensure that wireless devices and networks work first time, every time, and our customers' products are launched on-time and on-budget.
The multipath emulator is designed to create the conditions described by the TGn-B channel model, as detailed in IEEE 802.11-03/940r1. Two clusters are produced, spaced from one another by 20 ns of delay, each cluster produces a series of taps, which decay exponentially. The system includes 4 individual channels with a bypass switch in each one, allowing the user to bypass the multipath simulator, creating the conditions described in the TGn-A channel model. Additionally, the system includes a programmable phase shifter, allowing the user to precisely tune the frequency response.
The USB-LAN attenuator provides four channels of attenuation controllable via either USB 2.0 or 10/100Base-T Ethernet interfaces. The attenuation channels can be operated independently or in a synchronized fashion where all attenuators change simultaneously.
The Ethernet port supports 10/100BaseT operation, with auto-negotiation of the interface speed and duplex mode. TELNET server is provided for a command-line interface that implements many of the functions of the serial console CLI, and an HTTP server that allows control via a browser or JQUERY.
The Wi-Fi 6E Multipath Emulator is available in a rack-mount enclosure that measures 19 x 12 x 3.5 inches with SMA-female connectors. This USB powered emulator is ideal for MIMO conductive testing, Wi-Fi 6E/WiMAX/4G LTE/5G multipath fading simulators, and engineering/production test lab environments.
