Wireless personal testbeds



octoBox 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 model reflections of a typical room. A built-in plastic turn table inside the octoBox enables rotation of the device during the test or precisely orients the device antennas to determine nulls and peaks in the antenna propagation pattern.

octoBox is the main building block of the octoBox stackable wireless testbeds. It provides excellent MIMO environment for maximum over the air (OTA) throughput. It supports a variety of filters for high speed data, video and power that enable you to control the devices inside without breaching the isolation of the octoBox.

Filters are key for a small chamber testbed. When testing in a traditional walk-in chamber, all the equipment comprising the testbed is in the same physical space as the DUT, so cabling such as Ethernet, USB, HDMI, etc. can be directly connected. When testing in a small chamber such as the octoBox, these cables have to get to the DUT through the walls of the chamber. How to get these cables through without breaching the isolation of the octoBox? Filters are the answer.

octoBox high speed data filters pass the high speed data signals while rejecting the frequencies of wireless transmission. Rejection band starts at 700 MHz and extends to over 6 GHz. octoBox filters include gigabit Ethernet with POE (power over Ethernet), USB, HDMI, 3.5mm phono and DC power.

octoBox also features a waveguide filter for feeding fiber optic or other non-conductive cables through to the devices inside.

Antenna kits, shelves and other options shown below make octoBox easily adaptable for a variety of test configurations.

octoBox model BOX-38-TT features a built-in turn table. The turntable enables software controllable DUT rotation while you measure throughput, RX sensitivity and other parameters.
