FreedomPop, which offers 500MB of free wireless data service a month via Clearwire’s WiMAX service on a range of devices, has a better offer for tablet owners coming in the second half of this year.

The FreedomPop Clip is designed to attach to Wi-Fi only tablets and provides wireless Internet connectivity when away from Wi-Fi. Better still, the service will be free for the first 500MB of usage each month and will support Sprint’s up-and-coming 4G LTE network for faster browsing. The add-on hardware only weighs 2.5 ounces and has its own built-in rechargeable battery estimated to last up to six hours.

Tablets enabled with support for mobile data networks have never sold particularly well because of the added cost and expensive two-year contract required to maintain the service. Instead, some customers tether their tablets or enable an add-on Mobile Hotspot feature on their smartphone, which can cost $30 extra per month. The new FreedomPop Clip does not come with a contract or a monthly fee when users keep browsing to under 500MB each month. The forthcoming device will also support up to eight extra connections, in case you want to share.

Those who want more data, and around 30 percent of FreedomPop’s customers reportedly do, they can buy it on-demand without any contract or commitment. If you bug your friends to also buy the device, you can earn additional free browsing. In fact, FreedomPop will try and encourage sharing by including a new “open Wi-Fi” Internet service on a separate SSID. Those connecting through the open feature will likely get a marketing message encouraging them to get their own FreedomPop device, and their usage won’t count against your allowance.

FreedomPop Clip supports Sprint’s up and coming LTE 4G network.

Stop the Cap! has FreedomPop’s $99 iPod Touch add-on device, which works exclusively on Clearwire’s network. We’ve used it for about five months and can report the device works well whether you actually have an iPod or not. It is simply a portable hotspot shaped to clip to the back of the 4th generation iPod Touch (it won’t fit ours). But even if it cannot clip on, it still delivers excellent signals up to 12 feet away from the MP3 player.

Its biggest weakness is Clearwire’s hit or miss network. Here in suburban Rochester, N.Y., Clearwire provides service through a nearby cell tower about a mile away. At home, the device works with fair reception indoors, but really needs to be near a window to perform reliably. Outdoors, the device works much better. We found more trouble trying to use the device in a nearby restaurant and while in downtown Rochester because Clearwire reception proved spotty. When it does work, it provides an average of 800kbps-1Mbps downstream speeds, which is superior to most 3G networks, but does not come close to what Verizon’s LTE network can deliver. But then, FreedomPop data comes free.

Just remember to keep usage at 400MB or less every month. As you approach 500MB of usage, FreedomPop will “conveniently” bill you for additional usage it anticipates you will use unless you remember to shut this auto top-up feature off on FreedomPop’s website control panel. You must also use at least 5MB a month to keep the device active, so remember to power it up at least once a month and do some browsing.

The FreedomPop LTE-capable Clip will also reportedly work with 3G service, according to Forbes. This is an important consideration because Sprint’s 4G LTE network is still in its infancy and not yet available in most major metropolitan areas. But if it relies on Sprint’s overwhelmed 3G network, expect much slower performance.

The selling price for the device itself has not yet been announced, but we expect it will be available later this year at $99 or slightly higher.

Netflix has introduced 3D and Super HD viewing — an improved version of 1080p streamed content — but if you are a Time Warner Cable broadband customer, you will not be able to watch.

Netflix is distributing its highest definition content over its Open Connect CDN network, which minimizes the geographic distance and number of connections between viewers and Netflix’s streaming servers. ISPs can join Netflix Open Connect either by free peering at common Internet exchanges, or save even more in transit costs by putting free storage appliances supplied by Netflix in or near their network.

“OpenConnect provides Netflix data at no cost to the location the ISP desires and doesn’t seek preferential treatment,” Netflix tells GigaOm. “We hope Time Warner will join the many major ISPs around the world who are participating in Open Connect to reduce costs, minimize congestion and improve data delivery to enhance the consumer experience.”

So far, Time Warner Cable has chosen not to participate and accused Netflix of discriminating against its customers.

“While they call it ‘Open Connect,’ Netflix is actually closing off access to some of its content while seeking unprecedented preferential treatment from ISPs,” Time Warner Cable said in a statement to Multichannel News. “We believe it is wrong for Netflix to withhold any content formats from our subscribers and the subscribers of many other ISPs. Time Warner Cable’s network is more than capable of delivering this content to Netflix subscribers today.”

ISP participation in the Netflix Open Connect CDN has proven limited thus far in the United States. Cablevision is the only major cable operator signed on to the content delivery platform. Frontier, Google Fiber and Clearwire also participate. Abroad, Virgin Media, British Telecom, Telmex and Telus also participate.

Netflix’s decision to limit its best streams to participants may be an attempt to force ISPs to take its content delivery network more seriously and enlist subscribers in a push to get additional ISPs on board. By bringing its most watched content directly to ISP’s, the company is attempting to blunt provider arguments for data caps and other viewing limits because the cost to distribute content within a provider’s internal network is negligible.

The necessary hardware powering the Netflix Open Connect CDN is less than you might think. The single device powering Open Connect is easily rack mountable and consists of:

Eshoo

Rep. Anna Eshoo (D-Calif.), the ranking member on the House Energy and Commerce Communications Subcommittee, will shortly reintroduce legislation that will require wireless companies to disclose more information about the anticipated speeds of their 4G wireless networks.

Eshoo announced her legislative intentions Tuesday at the Broadband Breakfast Club, telling attendees it was important for consumers to know what they are getting before signing a two-year contract.

The anticipated legislation is expected to mirror Eshoo’s 2011 bill — the Next Generation Wireless Disclosure Act (HR 2281), which never made it out of the Republican-dominated House committee.

Eshoo said consumers need clear and concise explanations of data limits, caps, or network management policies that can turn a fast 4G connection into a very slow or expensive one.

Many of the former bill’s supporters echoed carriers use “4G” as a marketing tool which can lead to consumer confusion. Networks ranging from Clearwire’s WiMAX service to T-Mobile’s HSPA+ to Verizon Wireless’ LTE network have all been dubbed “4G,” despite offering widely varying maximum speeds.

Consumers have also faced bill shock when they do not understand their monthly data limits.

Like the last bill, Eshoo’s newest effort is expected to face stiff opposition from wireless carriers and House Republicans, but may raise the temperature on data caps at the Federal Communications Commission, which has faced increasing pressure to become more involved in the issue of usage limits and consumption pricing.

Clearwire wants a divorce from customers it deems are using the wireless broadband service too much — as in around 5GB per month, despite the fact many of those customers pay for “unlimited” accounts.

Broadband Reports says several ex-customers are now complaining on Twitter about their abrupt, involuntary departure this week as paying customers, despite company promises that advance warnings would be sent if a customer was engaged in “excessive use.”

“One user excessively running heavy bandwidth applications can adversely affect the speeds and service quality for their neighbors,” Clearwire told Broadband Reports. “It is rare that we take this step and when we do it affects an extremely small percentage of our total user base. We typically contact users to notify them of this type of situation first in order to provide an opportunity to make necessary changes.”

Broadband Reports:

How much usage was considered too much? Clearwire won’t get specific, but one of the users tells Broadband Reports Clearwire informed him he’d breached 5 GB three months in a row — which frankly doesn’t sound excessive for a modern wireless network.

Clear began throttling heavy users on unlimited accounts to around 256kbps back in 2010. They’ve never really been specific about what triggers the throttled state for users, given it appears to be calculated on the fly based on local tower congestion — so what triggers throttling may be different in different markets. It’s not entirely clear why throttling these users back to 256 kbps wasn’t substantial enough of a punishment for these “fired” customers.

We’ve received FreedomPop’s “Freedom Sleeve Rocket for iPod Touch” here at Stop the Cap! HQ and are giving it a run.

Originally slated for release in the late summer, the $99 sleeve finally arrived yesterday afternoon. FreedomPop’s attraction is 500MB a month of free Clearwire WiMAX usage indefinitely. After the upfront cost of the sleeve ($99), customers can snap the case-like sleeve on the back of their 4th Generation iPod and be on their way streaming content, making Skype calls, checking web pages/email, or sharing the connection with up to eight devices (or friends).

It could be a fine alternative for usage-capped wireless customers who want an extra 500MB edge every month, and if you’ve ever lost a cell phone while exercising (I have), this is a little less risky (and you will definitely notice because the iPod you are listening to will go missing with it).

Still, FreedomPop is a start-up and “free” wireless data sounds a little too good to be true (or at least long-lasting should the business model go awry).

Customers can earn additional usage allotments “connecting” with “Freedom Friends” or signing up for third party offers. If you like the service and want more, FreedomPop’s real business model kicks in — selling you additional data allowances that range from $7.25-$20/GB above and beyond your initial 500MB each month.

Clearwire’s hit or miss coverage in upstate New York.

So how does the device work? We’re testing it out this week and will report our results in greater detail sometime next week. But up front, some interesting observations:

1. The device seems durable enough. It can recharge from a USB port or from the included power adapter. Charging time initially took several hours, but we’re unsure how long it will run just yet;
2. A web-based control panel offers easy customization of the device, which appears as a Wi-Fi hotspot when the 4G service is enabled. You can reset your password and even manage the power level. The “low” setting proved more than adequate for anyone within 10 feet to connect, and since this was designed to attach to the back of your iPod, signal strength of its Wi-Fi service is no problem;
3. You better have a 4th generation iPod or else it simply won’t fit. I actually discovered I had a third generation unit, which means no luck snapping the iPod to the back of the sleeve. Apple’s newest iPod Touch won’t fit either. But then I discovered it really didn’t matter. I can slip the sleeve all by itself in a pocket and it will still work fine with my iPod, attached or not. FreedomPop also sells a small portable hotspot device that could work equally well if you don’t need a “snap-on” solution;
4. Clearwire, which has a dreadful reputation for reception and speed issues here in western New York, actually worked impressively well in early tests. Indoors we managed a medium strength signal from a cell tower located about two miles away. Clearwire’s very high frequency means outdoor reception free of obstacles like walls and doors will perform even better, and it did. We managed at least 1-3Mbps service at all times, which is better than a lot of cell carrier 3G networks locally;
5. Making and receiving VoIP calls using an earlier generation iPod Touch is a nuisance. We noticed audio dropouts and call dropping, and you need to supply a headset with a microphone to be able to speak to a caller. But who calls anyone anymore? Text messages and Google Talk’s instant message system worked much easier;
6. You can eat usage just browsing web pages. I was astonished to discover I consumed more than 42MB after less than 30 minutes of reading e-mail and web browsing a half-dozen news site web pages. At that rate, I’d be close to my limit after just 10 days. This surprised me because my Verizon Wireless data plan shows my spouse and I manage around 700MB of combined usage every month, and that includes streaming radio every morning on the ride to work. FreedomPop’s usage meter will need some closer inspection because there are indications it counts 1MB of usage for each hour the device is powered on, regardless of whether you are actively using it or not;
7. The second thing we did after unboxing was visit FreedomPop’s website and turn off “automatic top up” under Billing Settings. Otherwise after you reach 400MB (not a typo) of usage, FreedomPop will “conveniently” automatically add 1GB of additional usage for $20, billed to your credit card. Set in the off position, your account will simply stop working for the rest of the month once you hit 500MB.

I had low expectations from FreedomPop’s alliance with Clearwire, the WiMAX network Sprint customers love to hate (and then turn off on their phones to conserve battery life). But so far I am cautiously optimistic.

Readers should be careful before jumping in and check FreedomPop’s coverage map first because Clearwire’s network is notoriously limited. For example, here in upstate New York Rochester, Syracuse, Geneva, and Cortland are covered. Buffalo, Albany, and Binghamton are not. In the Big Apple, New York City has coverage, Long Island east of Valley Stream is out of luck.

We’ll post a more detailed review next week.
