Hasta La Gadget!

Today Clearwire yanked the cloth off of its rumored Clear Spot portable WiMax-to-Wi-Fi hotspot, a shiny little battery-powered device that lets you bestow real 4G bandwidth upon anyone in Wi-Fi range.

The $140 thing fits in your pocket, runs for four hours on a lithium-ion battery, connects up to 8 laptops via Wi-Fi, and works like a charm when you’re in a decent WiMax coverage area. (You still need to connect a WiMax modem, which costs $50 and requires a data plan.)

I tested it on the outskirts of Portland, at a Burgerville right off of I-5 in Vancouver, WA, essentially becoming a totally unwired, totally portable wireless hotspot for anybody with a computer or smartphone in the vicinity. Anyone can see the hotspot itself, as it has a standard Wi-Fi SSID, but once on, you have to enter a password, like you do in hotels or airports where the Wi-Fi network itself is technically public.

I can’t make enough of the experience, and how much it could change businesses, sales forces or mobile bloggin’ teams like Gizmodo. You don’t even have to be plugged in, you can just all hop on and work as usual for up to four hours, more if you can find an electric socket. And with WiMax, you’re not nearly as limited as you are with 3G—though there are some constraints, you at least have access to a network that, in certain coverage areas, bestows blistering broadband speeds similar those from today’s wired cable modems.

One big constraint, of course, is that WiMax from Sprint/Clearwire is currently limited to Baltimore and Portland, OR, but is growing this year and next to many cities.

There is also an internal limit to how much WiMax bandwidth you can harness. Since the Clear Spot uses the same Motorola WiMax USB modem that Clearwire sells for its standard WiMax service, I could test how well the bandwidth was passed through.

• What I got when connecting an HP Pavilion dv4 Windows laptop to WiMax: Around 7Mbps
• What I got when connecting the same modem to the Clear Spot, then connected MacBook Pro via Wi-Fi: 3-4Mbps

That does certainly represent a bottleneck, and there’s a reason for it: The wireless hotspot itself—which you might have seen under the brand Cradlepoint for a year or more—was designed for 3G, for whom 3Mbps downstream is a frickin’ miracle. It has a gimped USB port that throttles bandwidth over 5Mbps.

Though that’s a flaw, it’s not a big deal when you consider most Clearwire WiMax plans will be sold with a 4Mbps cap.

Beyond the hardware bottleneck, my other complaints are relatively minor:
• There’s no Ethernet port, so this can’t fundamentally replace home broadband.
• In areas of low coverage, you get an error message saying the modem was not found, which is inaccurate.
• There’s no good way to read WiMax signal strength on the device itself.

The good news for patient people is that, according to Scott Richardson, Clearwire’s chief strategy officer, the company is exploring selling an unfettered WiMax account, so you’d get an experience closer to the one I got in my uncapped testing. Also, Scott tells me there will be another portable WiMax-to-Wi-Fi hotspot device available—probably in the fall—that’s even smaller, and that wouldn’t be restricted by the USB bottleneck.

This is one of those products that’s totally niche but totally cool. Like, even if there are many people who are interested in getting WiMax, or better yet, a combo EVDO/WiMax modem from Sprint, I am not anybody would, at that point, also feel the need to share it with others. Maybe it’s good for bringing your work-supplied modem home, or maybe it’s a good way to split the cost of wireless modem service between a team of people who are always working together, on separate devices.

Regardless of all these scenarios, the fact is, it’s a truly new experience, and hopefully something we see more of in the future. I would say this is one of hell of a reason for Big Cable to be shaking in its boots—that is, if only Comcast wasn’t already part owner in Clearwire. [Clearwire Clear Spot release]

A cable modem in your pocket. Rockin’ down the highway with video on demand. Real wireless broadband. I tested an unthrottled Clearwire WiMax connection all over Portland, and that’s (mostly) what I got.

It’s hard to conceive of harnessing that much bandwidth wirelessly while sitting outside a shopping center, enjoying an unseasonably warm March day. It’s almost a joke, being able to watch Jon Stewart ream Jim Cramer—streamed via Hulu—while sitting in the backseat of a Lincoln Navigator doing 60 on the freeway. Having reviewed gadgets for almost a decade, I sometimes have to fake excitement that I may not truly feel in my loins. But this is different—real, honest-to-God wireless broadband made me freakin’ giddy, even if it didn’t deliver peak speeds at every spot where I parked.

If most of what we review is a chunk of the present, WiMax is from the future. Thankfully, it’s the near future.

The Test
Clearwire is a wireless data service now majority owned by Sprint (but with Comcast and others holding stakes). Currently it’s got the Clear WiMax service in both Portland and Baltimore. In Portland, it sells mobile and home modems that can pull down up to 4Mbps, but you know from reading Giz Explains that WiMax is already capable of a lot more: It’s the first 4G network that’s actually up and running in the US.

Clearwire gave me a chance to see what WiMax was like without any throttling: I got a USB dongle that could pull down whatever was out there. That turned out to be, in some places, nearly 13Mbps downstream—the current speed of your typical cable modem, and about 10 times what wired broadband delivered just a few years back.

I trekked around Portland, OR for a couple of days, testing the boundaries of the WiMax network, and spot testing in different locations around town to see what I got. I used the Motorola USBw25100 WiMax dongle, connected directly to a very sweet, very pimped-out HP Pavilion dv4 notebook that I borrowed for the occasion. (At the moment, there’s no Mac driver for the WiMax modem, but as you can imagine that’s in the works.)

As a helpful comparison, I used a 3G dongle from Verizon Wireless. I want to be clear that this isn’t to be read as a test of Verizon’s Portland network. However, that little USB modem held its own amazingly well, 3G beating 4G on a few occasions—at one point reaching a top speed of 3.3Mbps—so good on you, Verizon!

The tests were fairly simple, and resembled the ones we used for our Coast-to-Coast 3G Test last fall. I ran the Speakeasy Speed Test a minimum of five times in each location with each connection, then averaged those results. I loaded a very heavy page—the Wikimedia Commons Hubble Images page—at least five times, timing the pageload with the YSlow plug-in for Firefox. And I pinged local servers in three sets of 10 to determine latency. I chose locations based on their overall geographic variety, throwing in some locations that just made sense for me to visit, like my in-laws, and the family of my buddy Tom.

Here are the locations, neatly marked on the map, followed by a chart of test results:

Hot Spots and Cold Spots
As you can see, though I got the kind of awesomeness that blisters during three of my stops, I saw some mediocrity in three more, and in one location, smack in the center of town, I got nothing at all. When I checked with Clearwire, they not surprisingly told me I had accidentally chosen four locations that were slated for improved coverage, the two downtown locations set to get lit up in the coming months.

The up side of the experience was exciting enough that the downside didn’t bash my spirits. You’ll notice in the chart that even when the connection wasn’t that great, latency tended to stay low, and even when the connection was shabby, the download speeds tended to stay at or above 3G levels. I mean, before now, when was 1.2Mbps wireless considered a bad thing? Uploads were consistently just below 2Mbps—a far cry from the 10Mbps I can get with hard-wired cable, but pretty much on par with 3G.

Clearwire has to lease all of its cell towers just like any other wireless carrier, and not having a legacy network in place does keep it from automatically having a tower everywhere it’s needed. Also, the fact that WiMax runs in the 2.5GHz band points to a need for more towers. 3G is in the 1.8 to 2.1GHz, and the proposed LTE operates in the 700MHz spectrum. Though WiMax’s higher frequency may guarantee a more stronger signal closer in, it also has shorter range with the same power. WiMax doesn’t feel like Wi-Fi—it can handle smooth handoffs from tower to tower at high speeds—but the Clearwire coverage map of Portland does look a bit like a tightly packed collection of hotspots.

This can be good news: Clearwire knows every inch of the city, and can look up any customer’s home, workplace or favorite hangout to see if getting the service even makes sense. But it also means that if you’re not covered—depending on how a school board votes about what happens on their rooftops, or what the local port authority has to say about radio antennas—it may be a while before that changes.

Rockin’ Down the Highway
Like most carriers, Clearwire takes advantage the many tall cell towers that line the highway, meaning you get WiMax’s sick bandwidth pretty much unbroken as you fly down the road at 60 or 70 miles per hour. In the following video—in 90 quick seconds—you’ll see the following:
• Speakeasy speedtest showing roughly 13Mbps at 60 miles per hour
• Skype voice call (sorry we didn’t do a video conference)
• Slingbox video that’s being uploaded via WiMax at Clearwire’s office, and downloaded via WiMax in the car
• Hulu, where we load up and begin watching a full-screen episode of The Daily Show, at 70 miles per hour

In Summary:

It’s easy to reach download speeds that are four times the peak of today’s best 3G networks

Power demand does not seem to be any greater than other wireless connections

Most available Clear services now are capped at 4Mbps, though uncapped plans may be available sometime this year

Only a handful of cities will have this service in 2009, with more to come in 2010

Wide fluctuations in bandwidth feel weird: 12Mbps upside makes 3Mbps feel like a disappointing trickle

Within Portland’s city limits, there were plenty of dead zones that will hopefully be filled in soon

We can’t say a device such as this was inevitable or anything, but given how limited the adoption of WiMAX has been thus far in America, it’s definitely a win for everyone involved. According to Sidecut Reports, Clearwire will soon unveil a portable WiMAX / WiFi router built by Cradlepoint (prototype pictured), which will utilize a Motorola WiMAX USB stick to enable WiFi-capable devices to gather ’round and surf on the delightfully speedy WiMAX superhighway. In other words, non-WiMAX handsets that have WiFi modules can tap into the WiMAX network (if they’re in a lit locale, that is) via this device, which — if we may say so ourselves — is a brilliant design move. There’s no word yet on when the box will ship nor how pricey it’ll be, but this could be just the thing you’ve been looking for to replace that painfully expensive cable modem at home.
