FCC: Marriott used Wi-Fi jammers to block customers’ personal hotspots

One of the easiest ways to avoid sometimes exorbitant hotel fees for Wi-Fi connections is to simply bring your own network, either through your smartphone’s hotspot capabilities or through a standalone device. But if you haven’t been able to get a good signal at a hotel ballroom, it might not be your device’s fault: According to the Federal Communications Commission, Marriott has used Wi-Fi jammers to block personal hotspots at a hotel in Tennessee.

The FCC announced the results of its yearlong investigation on Friday, concluding that Marriott “intentionally interfered with and disabled Wi-Fi” networks at the Gaylord Opryland Hotel in Nashville, Tennessee. As a result of the investigation, Marriott will pay a $600,000 penalty to settle the complaint.

The investigation was spurred by an official complaint filed in March 2013. The user noticed that his mobile hotspot wasn’t working in the ballroom convention space and had faced similar issues at another Gaylord-branded hotel, which is Marriott’s line of convention-oriented hotels. Marriott did confirm that it used a Wi-Fi monitoring service that has “containment features,” which had been used to “prevent consumers from connecting to the internet via their own personal Wi-Fi networks.”

The investigation found that Marriott’s Wi-Fi monitoring system sent de-authentication packets to Wi-Fi hotspots. This use of radio frequencies to disrupt personal hotspots violated FCC spectrum use regulations.

Gaylord hotels apparently use Allot NetEnforcer products and services to provide and monitor Wi-Fi connectivity to its customers. One stated benefit of the hardware is that it “increase[s] revenue with tiered WiFi packages and upselling.” Allot brags that its products have helped Gaylord hotels create 40 different service plans for a single conference with broadband speeds as low as 256kbps. Allot does not appear to list Wi-Fi jamming as a feature on its website, but does offer some features that can target “rogue” access points.

Besides cost, there are several reasons why someone staying at a hotel or working at a convention center would want a personal Wi-Fi network. Often, hotels block certain sites you may need for your work or pleasure. Streaming and peer-to-peer media is usually throttled. And if you wanted to use a Chromecast or Apple TV to, say, show a presentation, it usually works better on a personal Wi-Fi network.

According to Yelp reviews, Wi-Fi is included at the Gaylord Opryland as part of a $18-per-night resort fee, although users can upgrade to “enhanced high speed” internet for $6.99 per day. Marriott also offers services like custom private networks for its business customers, which can cost anywhere from $250 to $1000 per wireless access point.

Like a lot of businesses, a rogue is anyone who isn’t giving you money.

so let me get this straight $600k in penalties, but they’ve collected multiple millions in fees…..I bet Marriott has jammers at almost every location….

All communications in the US are subject to rules that prevent interference to other licensed and unlicensed services. That little FCC tag on your FM radio certifies it won’t emit enough radiation (it DOES emit a very small amount) that your neighbors will be inconvenienced. This has at least been true since the 60’s, when I was a radio engineer — had to certify that our high power station wasn’t emitting enough accidental signal to affect well-designed TVs etc.

Hotel properties are part of the United States and subject to the same laws regarding citizens’ rights to use the airwaves. The actual MO of the interference is irrelevant.

If I were Gaylord, I’d send an invoice to the idiots that built and sold them the device. They are illegal on their face. Allot “implied suitability” by promoting the interference as a feature, which they should have known was illegal. I predict bankruptcy, as other countries also have similar laws; no place in the world for that crap.

Finally, One of the many reason I hated every time I had to go to a show at the Gaylord Opryland. I need WiFi access to process credit cards and I have the system on my phone. Almost 80% of the time I could not get a card to go through because I would have a connection and then it would be interrupted before the transaction could finish. I would have great service in my room but as soon as I went out into an Atrium or down into the Convention Center, I would get spotty service or nothing.

They aren’t the only ones who do this. This is industry wide.

Interesting case. I though that only RF jammers (layer 1) are illegal, but FCC say “prevent your Wi-Fi enabled device from connecting to the Internet; ”

I think all WiFi vendors (cisco, airtight, Aruba,hp, etc) use de-authentication frame (layer 2) in their WiFi (WIPS) systems for DOS attack protection. For trotting rouge clients is technique with manipulation with NAV, that could be also jamming.

Are they going consider as jamming systems ?
