Comment: Meraki and dense deployments (Score 1) 178

by batobin (#31455770) Attached to: Best WAP For Dense Crowds?

Hey everyone. I'm a software engineer at Meraki (mentioned earlier in the thread by dotwaffle) and wanted to chime in and offer what I can. Our gear is commonly used at conferences, including the most recent LeWeb, a conference in Paris with about 2,000 attendees and VERY heavy WiFi use (social media types that are tweeting, blogging, posting photos and accessing WiFi from their cell phones and laptops). We covered a 12,000 square foot room and other areas without any downtime or customer complaints. This was a huge improvement over the 2008 conference, when poor WiFi topped the list of attendee complaints.

Dotwaffle posted a link to our blog post about LeWeb which is worth re-linking. That photo was taken when the speaker asked everyone to hold up their iPhone.

We used MR14 access points with channel spreading and band steering enabled. This allowed us to use the entire wireless spectrum and avoid congestion on a single frequency (both of these are 1-click options when configuring your network). I'm happy to answer any technical questions you might have, or you can visit our website to learn more.

Mercury Contamination Vs. Energy-Efficient Lightbulbs 801

phyrebyrd writes "How much money does it take to screw in a compact fluorescent lightbulb? About US$4.28 for the bulb and labor — unless you break the bulb. Then you, like Brandy Bridges of Ellsworth, Maine, could be looking at a cost of about US$2,004.28, which doesn't include the costs of frayed nerves and risks to health."

New Solar Panel Design Traps More Light 334

GoSun wrote in with an article about new solar panels that opens, "Sunlight has never really caught fire as a power source, mostly because generating electricity with solar cells is more expensive and less efficient than some conventional sources. But a new solar panel unveiled this month by the Georgia Tech Research Institute hopes to brighten the future of the energy source." The new panels are able to produce sixty times the current of traditional models.

US University Dumps Windows to go All Mac 368

MacKeyser passed us a link to a MacWorld article about a University doing things a little differently. Instead of sticking with their inefficient mix of Apple and PC systems, the college is doing a 'total technology refresh', and adopting an all-Mac policy on the campus. Previously, a class at Wilkes University would be outfitted with something like 20 Macs and 20 PCs, to allow for individual preferences in software and OS use. With Boot Camp students at the Pennsylvania liberal arts college will be able to switch between Windows and OSX, choosing which applications and OS to use at any given time. "[Scott Byers, vice president for finance and the head of campus IT said] 'We think it will save $150,000 directly, in buying fewer units - even though the Macs cost more per unit than PCs.' The school, which enrolls about 4,000 undergraduate and graduate students, will reduce its inventory from nearly 1,700 computers to around 1,450 after the change over. Other costs savings, however, will be harder to measure. 'By standardizing, the IT department should be more productive,' Byers said."

The goal of Computer Science is to build something that will last at least until we've finished building it.
