Test wireless devices & emulate their networks in semi-anechoic box

May 30, 2016 // By Martin Rowe
Testing wireless devices requires that you either just put them into live situations and hope for the best or emulate their conditions and analyze their actions. octoPal from octoScope lets you emulate cellular base stations, routers, and access points.

The device is a supplemental product for the octoBox, letting you not only emulate wireless devices, but control antennas inside the box to emulate signal conditions, including MIMO. Wi-Fi emulation supports 802.11 a, b, g, n, and ac. octoBox itself is a small semi-anechoic chamber offering complete isolation from external interference thanks to its high-rejection filters for data and power connections. With metal surfaces covered by absorber foam, octoBox dampens reflections, making the small space inside function as a big room. A built-in plastic turn table enables rotation of the device during the test or precisely orients the device antennas to determine nulls and peaks in the antenna propagation pattern.

In addition to emulating network condition for performing functional tests, octoPal can monitor communications and test for throughput, packet loss, packet latency, packet jitter (RFC2544), data and channel-rate adaptation, coexistence, and other parameters. Used in conjunction with octoScope iGen, octoPal can emulate conditions that a wireless device might encounter in the field such as fading and multipath. When used with octoBox quadAtten, octoPal can change signal strength on up to four antennas.


octoPal connects to a remote computer through a browser, letting you collect test data and configure the device. It's also operable through an API (application programming interface) where you can automate tests through scripts. You can operate up to 32 octoPals in one test bed. Octopals can be operate in groups of 4, 8, 16, or 32 to add realism to the test bed's signals.
