Anechoic Chambers
The anechoic and semi-anechoic chambers constitute the epicenter of wireless performance evaluations. These evaluations includes testing wireless equipment, such as gateways and Wi-Fi access points to capture performance characteristics in a controlled environment. This lab can also pinpoint underperformance issues throughout the equipment development cycle, potentially leading to cost savings. We can provide a comparison of products for various deployment scenarios or purchasing decisions. Partner with us to design custom test cases to address unique performance issues.

This capability supports over-the-air testing of Wi-Fi and mobile networks. It has been used to test and validate mobile virtual network operator (MVNO) offload strategies. These strategies include dual-SIM device and home routing/local break-out roaming, low-latency Wi-Fi and interconnection with DOCSIS® testing, dual-SIM/dual-standby testing of phones, development of dual-channel Wi-Fi and more. Like an RF chamber, it’s built to reduce RF ingress and egress, creating conditions that allow our experts to validate proofs of concept for new technologies.
Lab Equipment and Capabilities

Two RF isolation tents

Access to HFC network and 4G network

Conductive sub-floor, conductive ceiling tiles and conductive paint that contribute to the overall RF isolation of over 120 dB
