You Are a Rogue Device

The user’s guide for one of Aruba’s recent software products states: “The wireless network has a wealth of information about unassociated and associated devices.” That software includes “a location engine that calculates associated and unassociated device location every 30 seconds by default… The last 1,000 historical locations are stored for each MAC address.”

For now, Seattle’s mesh network is concentrated in the downtown area. But the SPD has indicated in PowerPoint presentations—also acquired by The Stranger—that it hopes to eventually have “citywide deployment” of the system that, again, has potential surveillance capabilities that the SPD declined to answer questions about. That could give a whole new meaning to the phrase “real-time situational awareness.”

This is why you should always have wifi  disabled, in “airplane mode,” turned off when not in use.  Only turn on wifi for your device manually when you need to use a network.  Doing this also extends battery life because running the radio interface uses a lot of juice.  This network they built in Seattle would have great public benefit if it were open for all to use and there’s few engineering reasons why it can’t be.   Since emergencies are rare may as well utilize it and then kick people off indiscriminately when the network truly is needed.  I suspect however it’s not open for use by the rabble.  Another blurb from the article:

It’s reasonable to assume that locally gleaned information will be shared with other organizations, including federal ones. An SPD diagram of the mesh network, for example, shows its information heading to institutions large and small, including the King County Sheriff’s Office, the US Coast Guard, and our local fusion center.

Fusion centers, if you’re unfamiliar with the term, are information-sharing hubs, defined by the Department of Homeland Security as “focal points” for the “receipt, analysis, gathering, and sharing” of surveillance information.

At least if they’re going to spy  provide some value to the spied upon “user.”

High-gain patch antennas boost Wi-Fi capacity for Georgia Tech

Patch antennas focus the radio beam within a specific area. (A couple of vendors, Ruckus Wireless and Xirrus, have developed their own built-in “smart” antennas that adjust and focus Wi-Fi signals on clients.) Depending on the beamwidth, the effect can be that of a floodlight or a spotlight, says Jeff Lime, Ventev’s vice president. Ventev’s newest TerraWave High-Density products focus the radio beam within narrower ranges than some competing products, and offer higher gain (in effect putting more oomph into the signal to drive it further), he says.

At Georgia Tech, each antenna focused the Wi-Fi signal from a specific overhead access point to cover a section of seats below it. Fewer users associate with each access point. The result is a kind of virtuous circle. “It gives more capacity per user, so more bandwidth, so a better user experience,” says Lime.

Raspberry Pi as an Ad Blocking Access Point

This tutorial will show you how to use your Raspberry Pi as a WiFi access point that blocks ads by default for any devices using it. This is really neat in that it would work for your Android or iOS device, your Xbox 360, TiVo, laptop, and more without needing to customize any of those devices other than to use your Raspberry Pi as the access point for WiFi. Using an ad-blocker can be useful for conserving bandwidth, helping out low-power devices, or for keeping your sanity while browsing the web!

Aruba Networks Replaces Cisco in Starbucks

Google will eventually be completely replacing all the routers with its Aruba gear. It expects the process to take 18 months. Cisco would not confirm if it was the exclusive supplier for AT&T’s 7,000 store deployment, but it’s safe to say it will be getting the boot from several Starbucks locations, in the least

What is AP Isolation Mode and why should I disable it on my router?

In the computer networking world, AP stands for Access Point, or in this case, a wireless access point. AP Isolation effectively creates a “virtual” network among wireless clients, in which each device is an individual entity that cannot communicate with other wireless devices on the same Wi-Fi access point. This configuration can be useful for public Wi-Fi hotspots to separate potentially malicious network traffic from other.

The tomato router has this option.  Other APs do not.

Gov’t will open up radio spectrum to improve Wi-Fi

The Wi-Fi traffic jam was predictable, just as it’s predictable that there will be a mobile spectrum crunch, he said. 195 MHz of new spectrum will be opened up, all in the 5 GHz band, which has less interference but shorter ranges than the 2.4 GHz band. Opening up more spectrum has the potential to alleviate Internet-use congestion, particularly at crowded places like public Wi-Fi access points.

New WiFi protocol boosts congested wireless network throughput by 700%

To solve this problem, NC State University has devised a scheme called WiFox. In essence, WiFox is some software that runs on a WiFi access point (i.e. it’s part of the firmware) and keeps track of the congestion level. If WiFox detects a backlog of data due to congestion, it kicks in and enables high-priority mode. In this mode, the access point gains complete control of the wireless network channel, allowing it to clear its backlog of data. Then, with the backlog clear, the network returns to normal.

Ruckus Wireless Goes for an IPO

Ruckus sells its Wi-Fi access points, controllers and gateways to service providers as well as enterprise customers. The company says it has 45 carrier customers, among which are Bright House Networks , The Cloud , KDDI Corp. , Tikona Digital Networks Pvt. Ltd. , Time Warner Cable Inc. (NYSE: TWC) and Towerstream Corp. (Nasdaq: TWER). (See Ruckus Makes Over KDDI With Wi-Fi Offload.)

ZoneFlex Outdoor | Ruckus Wireless

ZoneFlex outdoor access points uniquely combine dynamic beamforming and adaptive meshing to enable a new level of outdoor performance at the lowest cost. Built to withstand the harshest of outdoor conditions, they’re designed with the flexibility to function as standalone APs or as managed devices, using the same wireless controller as their indoor Smart Wi-Fi products. If no Ethernet cabling is available, the outdoor AP meshes seamlessly with the indoor access points.

San Jose tries again with free downtown Wi-Fi

The IEEE 802.11n network from Ruckus Wireless is designed for outdoor public use, with multiple antennas and beam-forming mechanisms to get around obstacles. It will be implemented by system integrator SmartWave Technologies.

via San Jose tries again with free downtown Wi-Fi.

San Jose’s new system will replace a series of public hotspots that the city set up with partner MetroFi in 2004. Those networks were supported by advertising, but the arrangement fell apart when MetroFi went out of business in 2008. The annual $22,000 operational cost for the single new network will be about equal that of the old hotspots, Sammeta said.
