802.11n Interoperability Tests

We could easily spot available networks and see where connectivity problems were located.

802.11n Interoperability Tests – Belkin client 2

We could easily switch between Belkin’s Utility and the Windows XP supplicant.

802.11n Interoperability Tests – Belkin client 3

Belkin provides simple and advanced security configuration screens.

802.11n Interoperability Tests – Belkin AP 1

The N1 Router ships with Protected Mode enabled by default. We disabled it, however, because of our clean RF testing environment.

802.11n Interoperability Tests – Belkin AP 2

Belkin supports both the PSK and Enterprise versions of WPA and WPA2.

802.11n Interoperability Tests – Buffalo error

If a user logs in with the wrong credentials, the N-Finiti Router tells the user what the right log-in name is.

802.11n Interoperability Tests – Buffalo wireless 2

The N-Finiti router can select channel placement, or we could do it ourselves.

802.11n Interoperability Tests – Buffalo wireless 3

We could not manually set the channel to 1 or 11 if in 40MHz mode.

802.11n Interoperability Tests – Buffalo security

The N-Finiti products do not support WPA2 or the Enterprise flavor of WPA.

802.11n Interoperability Tests – Netgear advanced

Not many wireless options to configure.

802.11n Interoperability Tests – Netgear 3

The Netgear client Smart Wizard seemed a little sluggish to scan the airwaves in tests.

802.11n Interoperability Tests – Netgear 4

The Wizard quickly walked us through the steps for configuring and saving a wireless profile.

802.11n Interoperability Tests – Netgear client 2

A quick view of the channels being used and the link rate.

802.11n Interoperability Tests – Belkin 40

A clean shot of the Belkin products filling a 40 MHz channel, taken from a spectrum analyzer directly between client and AP at short distance.

802.11n Interoperability Tests – Wide channel

A different view of a 40MHz channel with spectrum analyzer located off to the side.

802.11n Interoperability Tests – Cisco

What a 20MHz channel looks like in comparison.

802.11n Interoperability Tests – Netgear close, then far

Swept spectrogram view of a 40MHz connection at 40 feet (upper) and 95 feet (lower).

802.11n Interoperability Tests – Unencrypted throughput

802.11n Interoperability Tests – AES-encrypted throughput

802.11n Interoperability Tests – Interoperability matrix

802.11n Interoperability Tests – Belkin shipping code vs. beta

802.11n Interoperability Tests – Belkin router

The Belkin routers LED indicators provide useful status info.

802.11n Interoperability Tests – Buffalo AirStation NFiniti

The Buffalo routers antennas can be rotated separately; full range of motion can be tricky.

802.11n Interoperability Tests – Netgear router

The Netgear routers antennas are embedded in the chassis.
