Teaching Science with Wi-Fi (Thanks, Ruckus and MetaGeek!)

This is why we can't have nice things...

As a parent, especially a techie one, you never know when a teachable moment is going to appear. Last night, I mentioned that I was testing a new Ruckus access point and enthused about how fast it was. My 12-year-old asked, “why is it so fast?” This led to a wonderful discussion about radio waves, congestion and propagation, and spectrum licensing. Yeah, I’m that kind of dad.

Wireless Field Day 2 – Silicon Valley

A year ago, Gestalt IT hosted our very first Wireless Field Day, and the event was a smashing success. This year, we are pleased to have a number of new delegates and sponsors and have added an additional event, the Wi-Fi Mobility Symposium.

Wi-Fi Mobility Symposium – San Jose, CA

I’m really looking forward to the second “symposium” organized by Gestalt IT in association with Tech Field Day. On January 25, the day before Wireless Tech Field Day 2, a number of top thinkers in the field of Wi-Fi will be part of the day-long Wi-Fi Mobility Symposium.

Which Apple Devices Support 802.11n Wi-Fi?

Apple boasts that their AirPort Extreme base station is "5x faster" but which devices can connect?

It is nice to see Apple out in front with a technology like 802.11n, considering their reluctance to support Blu-Ray and USB 3.0. Although expensive, the AirPort Extreme and 2011 MacBook Pro and iMac sport top-of-the-line specs and high performance Wi-Fi. But the lack of 5 GHz support across the board means many users will stick to the crowded 2.4 GHz spectrum, limiting performance.

Hands-On Review: The Eye-Fi Connect X2 Card

"Failed to initialize the Eye-Fi card" is an all-too-common error message. Eject it and try again...

I simply cannot recommend any Eye-Fi card, even the fancy new X2 line, to average camera users. Even enthusiasts like me would be wise to curb their enthusiasm. Most features barely work in practice, and the device frequently failed to perform.

What Are The True Eye-Fi X2 802.11n Wi-Fi Capabilities?

The Eye-Fi X2 card packs a 200 MHz ARM CPU and limited Marvell 802.11b/g/n Wi-Fi chipset

Eye-Fi (the company) would rather that we focus on the capabilities of their card rather than its technical components. But any self-respecting geek is going to want to know what makes it tick! I’d rather not cut open my card to get a peek at the chips inside, but Eye-Fi released some official details about the components used in the X2 series of cards, and a quick Google search revealed all that I needed to know.

Not All 802.11n Networks Are Alike

802.11n is a package of enhancements, most of which are optional

Buyers of 802.11n wireless network equipment should not assume they will see a great benefit right out of the box. Most will have to enable by hand a high-performance configuration including wide channels and 5 GHz operation. And some client devices may never reach the levels of performance expected by consumers due to hardware limitations.

Introducing the Eye-Fi X2 Card

The Eye-Fi promises simple connectivity for digital cameras, but does it really work?

One reason the smartphones like the iPhone are gaining ground on purpose-built cameras is their instant connectivity: Take a photo and you can immediately share it on Twitter, Flickr, Facebook, or other popular sites. Wouldn’t it be great if your SLR or digital camera could do the same? This is the promise of the Eye-Fi card: It adds Wi-Fi connectivity to most popular cameras, enabling you to transfer photos directly to your laptop or the Internet. If only it worked.

Snooping on AirDrop in Apple’s Mac OS X 10.7 “Lion”

AirDrop enables direct file sharing over Wi-Fi

Apple has aggressively moved to eliminate “superfluous” peripherals and connections, wiping out the floppy and now selling a number of machines without optical drives. AirDrop continues this progression, attacking the prime use case for USB flash drives.
