His name was LANBERT and he came from the west
To show which cables sucks and which are best
With a push of a button it’s doing it’s stuff
Hopefully for mGig the existing wire is enough…
Oh looky there, this one passes just fine
That LANBERT just saved us money and time
–Ode to LANBERT, by Wendall Pissmont Jr
There’s a new Bert in town… forget about Reynolds*, Bacharach*, and that whiny neurotic muppet from Sesame Street. Them cats is yesterday. NetAlly has recently introduced LANBERT (at Mobility Field Day 6), and if you are in the business of network wiring then you should pay attention.
This was easily one of the more thought provoking sessions of MFD6, says I. Let’s set the stage: you have an installed cable base, and are migrating access points to Wi-Fi 6 and 6E, and at long last we hopefully will see the massive throughputs that WLAN industry marketers have been telling us we should expect for years… like to the point where the old reliable 1 Gig uplink may not cut it. Do you need to replace that cable to get mGig performance?
LANBERT to the rescue! There should be no mystery when it comes to cabling performance capabilities. Many of us grew up knowing the value of cable certification testing, and now the free LANBERT app adds a much needed evolution to the notion.
Working with NetAlly’s Etherscope nXG and and LinkRunner 10G portable analyzers, LANBERT “generates and measures the transmission of line rate Ethernet frames over your network cabling infrastructure, qualifying its ability to support 1G/10G on fiber and 100M/1G/2.5G/5G/10G on copper links.” You are proving what an installed UTP or fiber run can really do despite what a certification report might say, without needing a standalone certification tester.
Test that existing cable for mGig before the new AP goes in, and don’t assume that “old” runs can’t support the new speeds.
I’ve long beaten the drum that the physical layer is critical to good networking. I’ve always viewed each part of a structured wiring system as it’s own component, worthy of note when it comes time for labeling, troubleshooting, and yes- performance testing. I’ve seen old cable work surprisingly well, and new cable disappoint for a number of reasons. There is simply no reason to guess how UTP and fiber will perform FOR REAL, with LANBERT. It’s the shizzle, baby!
*Yes, I know these dudes are actually named Burt and not Bert. Shut up.
