The Wi-Fi landscape has shifted significantly since SNB's Wi-Fi test process was last changed only a year ago. Distributed Wi-Fi (DW) / mesh systems have come on strong, challenging the single point routers that have formed the bedrock of the consumer Wi-Fi market to date. And MU-MIMO has moved down-market into less expensive products that lack connectorized antennas, making our direct-connect test method less practical.
The past year has also shown that having multiple test setups increased test time and was more prone to errors. The return to walking a laptop around to test DW products also increased test time. So some streamlining was in order.
The Revision 10 Testbed
We once again worked with our test partner octoScope to design the testbed for the Revision 10 process. The new testbed got moved up all the way to Revision 10 to line up with the name of the process it is used with. It can handle both single point routers and DW products of up to three modules. The top box is unchanged; it's still octoScope's Box-38 anechoic RF test chamber equipped with turntable and four octoScope high-gain antennas. Below that, however, everything is new.
The UNH-IOL Wireless consortium offers access to octoScope's octoBox and MPE testing equipment. This platform provides channel emulation and attenuation in an isolated testing environment for wireless devices up to four spatial streams, and provides the necessary conditions to attain consistent and repeatable testing results. In conjunction with IxChariot, it is used to perform Range vs. Throughput testing. visit the website
