Azimuth To Test 802.11n
Page 1 of 1
Shipping now to early access partners is the ADEPT-n MIMO test platform from Azimuth Systems of Acton, Massachusetts. The new single-box test solution is the latest from the company that provides test equipment used by the Wi-Fi Alliance for interoperability testing -- testing that will soon include checks on the 802.11n draft 2.0 specification.
What weve done is taken a rats nest of interconnections and put it all in the ADEPT-n box, says Jeff Abramowitz, Azimuths vice president of marketing. Unlike previous products like the W-Series chassis, which had separate blades for different kinds of test connections, the ADEPT-n integrates all the connectors, along with the RadioProof enclosures that a product resides in while testing.
11n has tremendous challenges for testing, says Abramowitz. Its a more complex standard than a/b/g, has a more complex physical layer and MAC, lots of options that were not in the previous specifications. Interoperability becomes that much more of a challenge with other MIMO products. MIMO stands for multiple in, multiple out, using multiple antennas for sending and receiving -- a cornerstone of 802.11n.
The older ADEPT-WFA (used by the Wi-Fi Alliance labs for testing) and the original W-Series chassis will not be phased out. Abramowitz says theyll still be needed by vendors who plan to make legacy 802.11a/b/g products -- the older standards for Wi-Fi will not be going away any time soon. Those with newer products will want to migrate to ADEPT-n, he says, but adds that Azimuth has had MIMO enclosures for almost a year, which can handle the job along with Director II.
