Disclaimer: *PCE-AC88 is a 4x4 MU-MIMO adapter. For full MU-MIMO operation it requires a MU-MIMO router with more than four spatial streams. Such routers are not currently available, but are expected to appear at a future date. Unless otherwise stated, all performance claims are based on theoretical performance. Actual figures may vary in real-world situations.
