Since Clearwire launched its 4G WiMAX network in Philadelphia in October, we’ve been itching to get our hands on a device that would let us utilize the high-speed wireless network.

With promises of speeds that blow away 3G connections that one might be used to on a mobile phone or USB modem, why not?

So we’ve taken the opportunity to test Sprint’s Overdrive 3G/4G Mobile Hotspot, a compact mobile WiFi router that lets up to 5 people simultaneously connect to Sprint’s WiMAX network.

It should be said that though Sprint, Clear and Comcast all utilize the same 4G WiMAX pipes, performance has been known to vary depending on the device. So while our tests here may indicate one speed, another device could produce a better or worse connection. We hope to test Clear and Comcast devices as the year goes on. [Full Disclosure: Clear is currently a Technically Philly advertising partner]

It should also be noted that the WiMAX network is being upgraded on a regular basis, so new towers are being installed in problem-areas where connection rates may have been poor during our tests produced earlier this year, officials tell us.

That said, we think our review is an interesting look at the network’s capability throughout Fairmount, Center City, Old City and Fishtown (complete with an interactive map of detailed throughput recordings). And we hope you’ll let us know how your 4G connection—whether on Sprint, Clear or Comcast—fares in your own neighborhood.

We love Sprint’s Overdrive 3G/4G Mobile Hotspot. Truly, for its tiny form-factor (not much larger than a deck of playing cards), there’s a lot packed in there.

Traditionally, mobile network carriers have offered up a USB modem that allows users to plug the device to their computer to connect. But with the increased bandwidth of 4G, Sprint opened up the floodgates. With the Overdrive, up to five users can connect to the device using WiFi. By choosing the router and typing in a short passcode digitally displayed on the device, it’s easy as hell to get connected.

The device is highly customizable through a slick Web interface that allows folks to change its password or enable more advanced features like port forwarding. We were a little disappointed by battery life, which tended to last for about 3 hours, but if you toted the USB cable along, you could charge the device right from your laptop.

Let’s talk price. The Overdrive currently costs $99.99 after a mail-in rebate and with a two-year commitment to Sprint’s $59.99 per month data plan. That’s pricey, sure, but it might be a good fit if you’re looking for a high-speed data connection in Philadelphia. We took the device for a test run in several neighborhoods in the city to see how worked in real-life conditions.


In our first test at a Fairmount apartment, we were disappointed to find that the device was only picking up a 3G signal, which mean low-bandwidth throughput. Off-the-bat, this was a bad sign for using the 4G network to replace in-home service. Further Testing in the same location elicited similar results.
Overall Performance: Poor

Later, in a coffeeshop a few blocks away, the service was strong, peaking at 2,500Kbps downloads and 900Kbps uploads. We were able to browse the Web with blazing efficiency, and we were impressed how much the experience resembled the wired cable connection we were used to.
Overall Performance: Excellent


Across from City Hall, we maintained an excellent connection to Sprint’s 4G network and we were able to reap the benefits. With two computers connected to the Overdrive, we were able to stream 720p HD video on both computers at the same time. The video played with little interruption, but a moment or two of buffering would have likely improved the experience. We were floored by the capability.
Overall Performance: Excellent

At a coffeeshop on 12th and Walnut, we had trouble simply opening our Gmail account. Able only to connect to Sprint’s 3G network there, we eventually gave up, turning to our paper notepad. Disappointment set in.
Overall Performance: Poor

But a few blocks South on Pine, we experienced notably better speeds, with downloads that peaked at 1,934Kbps but on the flip, occasionally dropped as low as 314Kbps. Inconsistency plagued the experience there.
Overall Performance: Good


On Church Street, we were able to maintain a strong connection that averaged at about 1,200Kbps, which mean browsing was brisk and we could perform normal work functions on-the-go. This is the type of experience we would hope for across the board.
Overall Performance: Good


Again, at a coffeeshop in Fishtown, we were able to maintain a strong connection without hiccup. Like our Old City tests, we were pleased to have a consistent connection. Though we missed the high-speed ridiculousness of streaming HD video on multiple computers in Center City, it was better to not have that than to not have access to our Gmail.
Overall Performance: Good


During a final, undocumented test in West Philadelphia, we stumbled upon one of the great failures of technology: consistency. While on deadline for a story, though performance had been better-than-average throughout our testing, we just couldn’t get either the 4G or 3G connection to give us enough juice to fire-off an e-mail when we needed it most. When your business may be on the line for a tight deadline, the question remains: can you trust wireless over a hardwired connection? That’ll be for you—and your wallet—to decide.

We will, however, remind readers that this network has only been launched for less than six months, and we expect improvements to be made. Though there has not been official announcements, we understand that towers will be installed to cover more of the region comprehensively. And that, we look forward to, for sure.

Overall Performance: Good

    I too have this service in the Fox Chase area and it is superb. The only time I had an issue was the day Sprint rolled out coverage to the central PA lines. I figured it was just a strain on the network because I was only able to get a 3G connection. I never move my Overdrive while at home, so this non-4G connection came as a bit of surprise, but at least the device can always roll back to 3G, where even then Sprint’s network defeated Cricket, the broadband modem I had before the Overdrive.

  • We went with Clear home and mobile back in November. Home service is decent. Better than DSL but not better than cable. I will accept this considering I will do everything in my power to avoid dealing with Verizon or Comcast. Download/upload speeds are consistent (3-5 down, 1 up). The connection will occasionally drop but always less than a minute.

    Mobile is a nice add-on I use this quite a bit. I have used it out in the suburbs and all over the city. Speeds vary like this tester experienced based on where you are. I have found a tower in the heart of Germantown where it hits 10+ MB down (uploads are capped at 1 MB).

    Like the Clear commercials & billboards I also tried streaming audio while driving. YouTube streams of ‘Keeping Up with the Kardashians’ flowed (almost) flawlessly. It did buffer once for a few seconds. This was while driving the hills between Germantown and East Falls.

    A second time streaming ‘Community’ on Hulu fared worse on our drive down Kelly Drive. Video buffered more than it played. We had similar issues trying to watch the same video in interior rooms in our house.

    Overall, a cool product for those on the move. I am hoping service continues to get stronger as they advertise. Clear just announced they are going to 18 more cities so your service now goes more places.

    This SUCKS!!! In my area I was told I had excellent coverage, but when I turned it on I only got 3 bars max! On top of the 3 bars I would get kicked out the internet every 45 minutes or so and I would have to restart the overdrive at least 8 times a day! I called Sprint the tech support said they were aware of this situation and that I was getting kicked off due to the fact that there are so many useres on at one time!!!! Wat the heck? Are they serious? They are promoting that up to 5 users can use this product at a time and when I only have 2 users using this product I get kicked out of my own internet. I’m returning this back and just going to go with cable or At&t.

    I’ve got the Samsung NC10 netbook with built-in Clear WiMAX. At my home in NoLibs I get a connect that claims to be excellent, but it will often drop every few minutes, which is very inconvenient, especially when I’m connected with my VPN. I haven’t yet contacted their support services yet; I wanted to check on line to see other people’s experiences and this article gives me some indication that I’m not necessarily having a unique experience.

    I got a 6-month free trial period that ends soon and I need to sort this out before I start paying for it.

  • Dizzledorf

    Tried the 4G Overdrive in a few locations including PHL airport, Clearwater, FL and the NW Philly Burbs. Poor performance everywhere, 2-3 bars max in areas listed with 4G coverage. Worse yet, when switching from 4G to 3G, the connection dropped altogether and needed to be re-established. A real productivity killer when trying to work via Remote Desktop, e.g. Returned the unit after 2 weeks.

  • Maxim

    Hey, I just moved to Powelton avenue and will be schooling at Drexel University. Is there any 4G coverage in these areas??? Is it worth buying an HTC Evo 4G that runs on Sprint???

    • Brian James Kirk

      Hey, if you look at the map on this post, we tested the 4G device in West Philly. That might be helpful.

    I own a Samsung Epic 4g and live in the Hopkinson House on Washington Square. I get no 4g at my floor (high) and none on the rooftop pool area. Furthermore, the 3g is weak and on the roof, I often don’t even have a cell phone signal. Sprint service is lousy in the Hop House. I would think that the higher you are, the better your signal but not with Sprint.

  • Anna

    Slow as molasses. I have had the Overdrive for a few months in West Philly (west of Penn’s campus). I cannot ever get 4G at better than 20 or 40%. I can get 3G at 80 or 100%, but that is still quite slow – I certainly cannot stream videos, and it takes forever to download large files. I have taken my device in to the Sprint repair place, and they are sending me another one, so we’ll see, but right now I not at all happy since I use this as my primary home connection. Overall, I would not recommend it to anyone.

    I hope Sprint is monitoring this site and does something about the spotty 4g coverage. I’m paying an extra $10/mo for the 4g and now I feel like a chump. I chalk it up to paying extra for the privilege of owning the Epic (which is a fine smart phone).
