How Well Do You Know Common WLAN RF Views?

OK, so maybe all of these aren’t exactly common. But none are particularly obscure or exotic, and all are part of my reality within a given week or month. See any that you haven’t seen before? Drop me a comment and I’ll share the origin of any that stump you. Thanks for playing our game!

How’d you do? I’ll admit, now that you’ve looked at them all, there’s one zinger in the mix that has nothing to do with WLAN. You can probably spot it, but curious how many can identify it.

MetaGeek Updates Chanalyzer

There are tools that WLAN support types tend to gravitate to en masse. When it comes to design work, the discussion gets more individualized as architects have their favorites among pricey tools; but put a bunch of WLAN folks who work in different capacities in a room together and you’ll find that most (if not all) of them have tools from MetaGeek in their everyday bag of tricks.

My own appreciation for MetaGeek’s USB-based tools goes back to the original 2.4 GHz Wi-Spy I purchased to see the effects of different classroom transmitting devices on our fledgling campus WLAN. Since then, I’ve marveled at where MetaGeek has been able to go for those of us shopping for decent, affordable, easy-to-use Wi-Fi support tools. I’ve bought a number of MetaGeek tools, and have also been fortunate enough to be on the receiving end of giveaways, like when MetaGeek presented at Wireless Field Day 5.

I like that MetaGeek keeps their fairly-priced tools fresh, both in response to changes in WLAN standards or just when there is room for improvement to make good even better. Like with Chanalyzer- which just got updated. Here’s my favorite new feature- the high-contrast Outdoor View color scheme:

This is a pretty drastic change from the traditional black background, and yes- it is easier to see outside in the daylight.

I also found the latest version (5.0.124) to have a much easier-to-use report building module, which is my second favorite thing about it. You can also have both 2.4 GHz and 5 GHz waterfalls active at the same time (if you have two suitable adapters), but I found this to crowd my little netbook display (though it would be handy on bigger screen).

Here’s the summary of what’s new, in MetaGeek’s own words:

NEW FEATURES

  • Improved Report Builder (specific list below)

  • Dual-band visibility. If multiple Wi-Spy DBx or 2.4x are plugged in, both waterfalls are displayed.

  • Optional outdoor color scheme with white backgrounds for better visibility in bright light.

  • Cisco CleanAir accessory (additional license required). Provides connectivity to view spectrum data collected from Cisco CleanAir access points.

  • Automatic update of OUI file to identify access point vendor by MAC address.

REPORT BUILDER IMPROVEMENTS

  • Created Report Builder menu item

  • Report Builder has merged with the Preview Pane

  • Simplified menus

  • Ability to add all blocks to a report with one click.

OTHER CHANGES

  • Improved licensing system

  • Improved color scheme

  • Moving the Unified Timeframe will now cause the timespan to pause in place.

  • Clicking on a table row highlights the entire row for ease of use.

  • Improved Filter usability

  • Improved fit and finish

Finally, for anyone keeping score, MetaGeek is part of the line-up for the upcoming most excellent WLAN Pro Summit 2014. (I hope to see many of you there.)
