Very Few Citizens Know What It Is, and Officials Don’t Want to Talk About It. by Matt Fikse-Verkerk and Brendan Kiley If you're walking around downtown Seattle, look up: You'll see off-white boxes, each one about a foot tall with vertical antennae, attached to utility poles. If you're walking around downtown while looking at a smartphone, you will probably see at least one—and more likely two or three—Wi-Fi networks named after intersections: "4th&Seneca," "4th&Union," "4th&University," and so on. That is how you can see the Seattle Police Department's new wireless mesh network, bought from a California-based company called Aruba Networks, whose clients include the Department of Defense, school districts in Canada, oil-mining interests in China, and telecommunications companies in Saudi Arabia. The question is: How well can this mesh network see you? How accurately can it geo-locate and track the movements of your phone, laptop, or any other wireless device by its MAC address (its "media access control address"—nothing to do with Macintosh—which is analogous to a device's thumbprint)? Can the network send that information to a database, allowing the SPD to reconstruct who was where at any given time, on any given day, without a warrant? Can the network see you now? The SPD declined to answer more than a dozen questions from The Stranger, including whether the network is operational, who has access to its data, what it might be used for, and whether the SPD has used it (or intends to use it) to geo-locate people's devices via their MAC addresses or other identifiers. Seattle Police detective Monty Moss, one of the leaders of the mesh-network project—one part of a $2.7 million effort, paid for by the Department of Homeland Security—wrote in an e-mail that the department "is not comfortable answering policy questions when we do not yet have a policy." But, Detective Moss added, the SPD "is actively collaborating with the mayor's office, city council, law department, and the ACLU on a use policy." The ACLU, at least, begs to differ: "Actively collaborating" is not how they would put it. Jamela Debelak, technology and liberty director of the Seattle office, says the ACLU submitted policy-use suggestions months ago and has been waiting for a response. Detective Moss also added that the mesh network would not be used for "surveillance purposes... without City Council's approval and the appropriate court authorization." Note that he didn't say the mesh network couldn't be used for the surveillance functions we asked about, only that it wouldn't—at least until certain people in power say it can. That's the equivalent of a "trust us" and a handshake. His answer is inadequate for other reasons as well. First, the city council passed an ordinance earlier this year stating that any potential surveillance equipment must submit protocols to the city council for public review and approval within 30 days of its acquisition and implementation. This mesh network has been around longer than that, as confirmed by Cascade Networks, Inc., which helped install it. Still, the SPD says it doesn't have a policy for its use yet. Mayor McGinn's office says it expects to see draft protocols sometime in December—nearly nine months late, according to the new ordinance. Second, and more importantly, this mesh network is part of a whole new arsenal of surveillance technologies that are moving faster than the laws that govern them are being written. As Stephanie K. Pell (former counsel to the House Judiciary Committee) and Christopher Soghoian (senior policy analyst at the ACLU) wrote in a 2012 essay for the Berkeley Technology Law Journal: The use of location information by law enforcement agencies is common and becoming more so as technological improvements enable collection of more accurate and precise location data. The legal mystery surrounding the proper law enforcement access standard for prospective location data remains unsolved. This mystery, along with conflicting rulings over the appropriate law enforcement access standards for both prospective and historical location data, has created a messy, inconsistent legal landscape where even judges in the same district may require law enforcement to meet different standards to compel location data. In other words, law enforcement has new tools—powerful tools. We didn't ask for them, but they're here. And nobody knows the rules for how they should be used. This isn't the first time the SPD has purchased surveillance equipment (or, as they might put it, public-safety equipment that happens to have powerful surveillance capabilities) without telling the rest of the city. There was the drones controversy this past winter, when the public and elected officials discovered that the SPD had bought two unmanned aerial vehicles with the capacity to spy on citizens. There was an uproar, and a few SPD officers embarked on a mea culpa tour of community meetings where they answered questions and endured (sometimes raucous) criticism. In February, Mayor Mike McGinn announced he was grounding the drones, but a new mayor could change his mind. Those SPD drones are sitting somewhere right now on SPD property. Meanwhile, the SPD was also dealing with the port-camera surveillance scandal. That kicked off in late January, when people in West Seattle began wondering aloud about the 30 cameras that had appeared unannounced on utility poles along the waterfront. The West Seattle neighborhood blog (westseattleblog.com) sent questions to city utility companies, and the utilities in turn pointed at SPD, which eventually admitted that it had purchased and installed 30 surveillance cameras with federal money for "port security." That resulted in an additional uproar and another mea culpa tour, much like they did with the drones, during which officers repeated that they should have done a better job of educating the public about what they were up to with the cameras on Alki. (Strangely, the Port of Seattle and the US Coast Guard didn't seem very involved in this "port security" project—their names only appear in a few cursory places in the budgets and contracts. The SPD is clearly the driving agency behind the project. For example, their early tests of sample Aruba products—beginning with a temporary Aruba mesh network set up in Pioneer Square for Mardi Gras in 2009—didn't have anything to do with the port whatsoever.) The cameras attracted the controversy, but they were only part of the project. In fact, the 30 pole-mounted cameras on Alki that caused the uproar cost $82,682—just 3 percent of the project's $2.7 million Homeland Security–funded budget. The project's full title was "port security video surveillance system with wireless mesh network." People raised a fuss about the cameras. But what about the mesh network? Detective Moss and Assistant Chief Paul McDonagh mentioned the downtown mesh network during those surveillance-camera community meetings, saying it would help cops and firefighters talk to each other by providing a wireless network for their exclusive use, with the potential for others to use overlaid networks handled by the same equipment. (Two-way radios already allow police officers to talk to each other, but officers still use wireless networks to access data, such as the information an officer looks for by running your license plate number when you've been pulled over.) As Brian Magnuson of Cascade Networks, Inc., which helped install the Aruba system, explained the possible use of such a system: "A normal cell-phone network is a beautiful thing right up until the time you really need it—say you've just had an earthquake or a large storm, and then what happens? Everybody picks up their phone and overloads the system." The network is most vulnerable precisely when it's most needed. A mesh network could be a powerful tool for streaming video from surveillance cameras or squad car dash-cams across the network, allowing officers "real-time situational awareness" even when other communication systems have been overloaded, as Detective Moss explained in those community meetings. But the Aruba mesh network is not just for talking, it's also for tracking. After reviewing Aruba's technical literature, as well as talking to IT directors and systems administrators around the country who work with Aruba products, it's clear that their networks are adept at seeing all the devices that move through their coverage area and visually mapping the locations of those devices in real time for the system administrators' convenience. In fact, one of Aruba's major selling points is its ability to locate "rogue" or "unassociated" devices—that is, any device that hasn't been authorized by (and maybe hasn't even asked to be part of) the network. Which is to say, your device. The cell phone in your pocket, for instance. 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." So how does Aruba's mesh network actually function? Each of those off-white boxes you see downtown is a wireless access point (AP) with four radios inside it that work to shove giant amounts of data to, through, and around the network, easily handling bandwidth-hog uses such as sending live, high-resolution video to or from moving vehicles. Because this grid of APs forms a latticelike mesh, it works like the internet itself, routing traffic around bottlenecks and "self-healing" by sending traffic around components that fail. As Brian Magnuson at Cascade Networks explains: "When you have 10 people talking to an AP, no problem. If you have 50, that's a problem." Aruba's mesh solution is innovative—instead of building a few high-powered, herculean APs designed to withstand an immense amount of traffic, Aruba sprinkles a broad area with lots of lower-powered APs and lets them figure out the best way to route all the data by talking to each other. Aruba's technology is considered cutting-edge because its systems are easy to roll out, administer, and integrate with other systems, and its operating system visualizes what's happening on the network in a simple, user-friendly digital map. The company is one of many firms in the networking business, but, according to the tech-ranking firm Gartner, Aruba ranks second (just behind Cisco) in "completeness of vision" and third in "ability to execute" for its clever ways of getting around technical hurdles. Take Candlestick Park, the San Francisco 49ers football stadium, which, Magnuson says, is just finishing up an Aruba mesh network installation. The stadium has high-intensity cellular service needs—70,000 people can converge there for a single event in one of the most high-tech cities in America, full of high-powered, newfangled devices. "Aruba's solution was ingenious," Magnuson says. It put 640 low-power APs under the stadium's seats to diffuse the data load. "If you're at the stadium and trying to talk to an AP," Magnuson says, "you're probably sitting on it!" Another one of Aruba's selling points is its ability to detect rogue devices—strangers to the system. Its promotional "case studies" trumpet this capability, including one report about Cabela's hunting and sporting goods chain, which is an Aruba client: "Because Cabela's stores are in central shopping areas, the company captures huge quantities of rogue data—as many as 20,000 events per day, mostly from neighboring businesses." Aruba's network is identifying and distinguishing which devices are allowed on the Cabela's network and which are within the coverage area but are just passing through. The case study also describes how Cabela's Aruba network was able to locate a lost price-scanner gun in a large warehouse by mapping its location, as well as track employees by the devices they were carrying. It's one thing for a privately owned company to register devices it already owns with a network. It's another for a local police department to scale up that technology to blanket an entire downtown—or an entire city. Aruba also sells a software product called "Analytics and Location Engine 1.0." According to a document Aruba has created about the product, ALE "calculates the location of associated and unassociated wifi devices... even though a device has not associated to the network, information about it is available. This includes the MAC address, location, and RSSI information." ALE's default setting is anonymous, which "allows for unique user tracking without knowing who the individual user is." But, Aruba adds in the next sentence, "optionally the anonymization can be disabled for richer analytics and user behavior tracking." The network has the ability to see who you are—how deeply it looks is up to whoever's using it. (The Aruba technology, as far as we know, does not automatically associate a given MAC address with the name on the device's account. But figuring out who owns the account—by asking a cell-phone company, for example—would not be difficult for a law-enforcement agency.) Geo-location seems to be an area of intense interest for Aruba. Last week, the Oregonian announced that Aruba had purchased a Portland mapping startup called Meridian, which, according to the article, has developed software that "pinpoints a smartphone's location inside a venue, relying either on GPS technology or with localized wireless networks." The technology, the article says, "helps people find their way within large buildings, such as malls, stadiums, or airports and enables marketing directed at a phone's precise location." How does that geo-location work? Devices in the network's coverage area are "heard" by more than one radio in those APs (the off-white boxes). Once the network hears a device from multiple APs, it can compare the strength and timing of the signal to locate where the device is. This is classic triangulation, and users of Aruba's AirWave software—as in the Cabela's example—report that their systems are able to locate devices to within a few feet. In the case of large, outdoor installations where APs are more spread out, the ability to know what devices are passing through is useful—especially, perhaps, to policing agencies, which could log that data for long-term storage. As networking products and their uses continue to evolve, they will only compound the "legal mystery" around how this technology could and should be used that Pell and Soghoian described in their Berkeley Technology Law Journal piece. Aruba's mesh network is state-of-the-art, but something significantly smarter and more sensitive will surely be on the market this time next year. And who knows how much better the software will get. An official spokesperson for Aruba wrote in an e-mail that the company could not answer The Stranger's questions because they pertained "to a new product announcement" that would not happen until Thanksgiving. "Aruba's technology," the spokesperson added, "is designed for indoor (not outdoor) usage and is for consumer apps where they opt in." This is in direct contradiction to Aruba's own user's manuals, as well as the fact that the Seattle Police Department installed an outdoor Aruba mesh network earlier this year. One engineer familiar with Aruba products and similar systems—who requested anonymity—confirmed that the mesh network and its software are powerful tools. "But like anything," the engineer said, it "can be used inappropriately... You can easily see how a user might abuse this ability (network admin has a crush on user X, monitors user X's location specifically)." As was widely reported earlier this year, such alleged abuses within the NSA have included a man who spied on nine women over a five-year period, a woman who spied on prospective boyfriends, a man who spied on his girlfriend, a husband who spied on his wife, and even a man who spied on his ex-girlfriend "on his first day of access to the NSA's surveillance system," according to the Washington Post. The practice was so common within the NSA, it got its own classification: "LOVEINT." Other Aruba clients—such as a university IT director, a university vice president, and systems administrators—around the country confirmed it wouldn't be difficult to use the mesh network to track the movement of devices by their MAC addresses, and that building a historical database of their movements would be relatively trivial from a data-storage perspective. As Bruce Burton, an information technology manager at the University of Cincinnati (which uses an Aruba network), put it in an e-mail: "This mesh network will have the capability to track devices (MAC addresses) throughout the city." Not that the SPD would do that—but we don't know. "We definitely feel like the public doesn't have a handle on what the capabilities are," says Debelak of the ACLU. "We're not even sure the police department does." It all depends on what the SPD says when it releases its mesh-network protocols. "They're long overdue," says Lee Colleton, a systems administrator at Google who is also a member of the Seattle Privacy Coalition, a grassroots group that formed in response to SPD's drone and surveillance-camera controversies. "If we don't deal with this kind of thing now, and establish norms and policies, we'll find ourselves in an unpleasant situation down the road that will be harder to change." The city is already full of surveillance equipment. The Seattle Department of Transportation, for example, uses license-plate scanners, sensors embedded in the pavement, and other mechanisms to monitor individual vehicles and help estimate traffic volume and wait time. "But as soon as that data is extrapolated," says Adiam Emery of SDOT, "it's gone." They couldn't turn it over to a judge if they tried. Not that license-plate scanners have always been so reliable. Doug Honig of the ACLU remembers a story he heard from a former staffer a couple of years ago about automatic license-plate readers on police cars in Spokane. Automatic license-plate readers "will read a chain-link fence as XXXXX," Honig says, "which at the time also matched the license plate of a stolen car in Mississippi, resulting in a number of false alerts to pull over the fence." Seattle's mesh network is only one instance in a trend of Homeland Security funding domestic surveillance equipment. Earlier this month, the New York Times ran a story about a $7 million Homeland Security grant earmarked for "port security"—just like the SPD's mesh-network funding—in Oakland. "But instead," the Times reports, "the money is going to a police initiative that will collect and analyze reams of surveillance data from around town—from gunshot- detection sensors in the barrios of East Oakland to license plate readers mounted on police cars patrolling the city's upscale hills." The Oakland "port security" project, which the Times reports was formerly known as the "Domain Awareness Center," will "electronically gather data around the clock from a variety of sensors and databases, analyze that data, and display some of the information on a bank of giant monitors." The Times doesn't detail what kind of "sensors and databases" the federally funded "port security" project will pay for, but perhaps it's something like Seattle's mesh network with its ability to ping, log, and visually map the movement of devices in and out of its coverage area. Which brings up some corollary issues, ones with implications much larger than the SPD's ability to call up a given time on a given day and see whether you were at work, at home, at someone's else home, at a bar, or at a political demonstration: What does it mean when money from a federal agency like the Department of Homeland Security is being funneled to local police departments like SPD to purchase and use high-powered surveillance gear? For federal surveillance projects, the NSA and other federal spying organizations have at least some oversight—as flawed as it may be—from the Foreign Intelligence Surveillance Court (also known as the FISA court) and the US Congress. But local law enforcement doesn't have that kind of oversight and, in Seattle at least, has been buying and installing DHS-funded surveillance equipment without explaining what it's up to. The city council's surveillance ordinance earlier this year was an attempt to provide local oversight on that kind of policing, but it has proven toothless. 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. If federally funded, locally built surveillance systems with little to no oversight can dump their information in a fusion center—think of it as a gun show for surveillance, where agencies freely swap information with little restriction or oversight—that could allow federal agencies such as the FBI and the NSA to do an end-run around any limitations set by Congress or the FISA court. If that's their strategy in Seattle, Oakland, and elsewhere, it's an ingenious one—instead of maintaining a few high-powered, herculean surveillance agencies designed to digest an immense amount of traffic and political scrutiny, the federal government could sprinkle an entire nation with lots of low-powered surveillance nodes and let them figure out the best way to route the data by talking to each other. By diffusing the way the information flows, they can make it flow more efficiently. It's an innovative solution—much like the Aruba mesh network itself.

Hi ya'll, I was up perusing the site and wiki and noticed there's not a clear/intuitive way to join the mesh. I understand this undertaking may be more difficult than just completing an online webform. However, we could add a page to PeoplesOpen which gives detailed instructions on how to start the process of adding a new node to the Mesh. Thoughts? -Luis

Changing the MAC address

by Jeremy Entwistle

*He wants to follow her around the city or simply learn where she lives. Using the node map, which includes node IP addresses (or because he simply drove around the city and mapped them out himself) he knows the IP/MAC to physical location mapping of all nodes.* I think this is a concern. I don't think anybody wants to go from the government having this ability to anybody having this ability. I'm not sure the best idea of implementing this, but what it sounds like it comes down to is the … [View More]identifier. We need something on the mesh which will allow 1) nodes communicate to nodes on the mesh and 2) nodes communicate to nodes through the internet (via a tunnelling program). Currently batman does this with MAC addresses, however, as we mentioned in a previous meeting, you can have duplicate MAC addresses because of the manufacturer (most likely problem) or randomly generated. I think it's possible to do the following: Client <-- MAC addresses --> Node Node <-- unique keys --> Node Exit Node < -- IP addresses --> Internet (or Tor Network) In the same way that the exit node serves as a barrier for the mesh to the internet, I think a node can do the same for MAC addresses of phones and it's locally connected devices. This should eliminate the need for disabling the traceroute function, which from what understand needs to be there in order for batman to determine a reliable and quick connection between nodes. The only complication I can think of being able to create your own unique key is to verify on the network that it's unique. It probably can be figured out with working with the DAT files. http://www.open-mesh.org/projects/batman-adv/wiki/DistributedArpTable *I see the localization possibilities as a feature which can empower local communities, where users can get services and content based on where in the mesh network they are. I see mesh networks as connections between people.* Agreed! I don't think by being the protocol to be anonymous makes it so that you have to remain anonymous. It just allows you to be anonymous by default. In my mind, I think it would be amazing to implement into the protocol something comparable to the networks on social media sites. Such that, I have a unique key as my address on the mesh, I run a server from my node and I want people to have access to it. However, maybe I have very good reason to want to change my key every couple of days, but I want to a specific group of nodes to know my address change. Then I think it would be important to allow that node update this group of nodes with your key change, once verified with the network as being unique. Or as mentioned, only sharing your key to a group of nodes (or a certain number of hops) then the packets being carried out by another identifier beyond that point. All that being said... I'm still learning and this may not work at all.

Re: [Mesh] mesh Digest, Vol 10, Issue 20

by Jeremy Entwistle

Okay, that's very true. Then what about interfacing nodes with clients on MAC addresses, but then node to node with a different address? Wouldn't that provide similar security as to what we're trying to do with exit nodes? The MAC address for the phones only being known to the node, but then not using it for delivery throughout the mesh.

Changing your MAC address

WNDW (Wireless Networking in the Developing World) in MarkDown

by Matthew Senate

Hey all, I got an .ODT source copy of the WNDW book, converted it to HTML with LibreOffice, then to MarkDown with Pandoc: https://github.com/wrought/wireless-networking-in-the-developing-world/ The HTML version is pretty nice. Here's the markdown version, which needs a bit of cleaning around the math: https://github.com/wrought/wireless-networking-in-the-developing-world/blob… I really wanted to send in some edits, figured this would help others as well. // Matt

Lessig's talk tomorrow at UC Berkeley

by Mitar

Hi! (Sorry for slightly off-topic posting.) Expanding on the debate that rages today about protecting all Americans' right to vote, Mr. Lessig will discuss the consequences of money's presence in politics and how those consequences may be remedied. Professor of Law and Director of the Edmond J. Safra Center for Ethics at Harvard University, Lawrence Lessig helped found the non-profit Creative Commons and has authored numerous books. We hope you will join us in this stimulating discussion as … [View More]
