Product Description

USB Adapter

The wireless USB adapter comes with a removable antenna and is fully compatible with 802.11b/g Wi-Fi standards. We ran throughput tests on this adapter running on the 1073 - PhidgetSBC3 using the Iperf network testing tool. At a range of approximately 10 meters through walls in our office, an average of 4.17 Mbps was recorded. Throughput depends on many variables including the performance of the computer running it and the operating system being used. You can read more of our test results here.
