I’m very curious to see what all the excitement is about for 4G. We just got a demo in this afternoon. Luckily I will be the first one here at Day to test it out.
3:09 PM
Put the Smartview install CD in my laptop, I didn’t have the software already installed.
3:15 PM
Installation finished, need to restart….
3:16 PM
The modem comes in a nice box. Looks like a $200 watch should be in there.
3:20 PM
Got it plugged into my USB port, there’s an accessory in the box to clip the modem to the screen so the antenna is up high.
3:21 PM
No WiMAX signal in my office….reverts to 3G. Have full bars for 3G but that’s not what I’ve been waiting for. Do a speed test just for kicks on speedtest.net.
0.76 mb/s down, 0.35 mb/s up….Seems reasonable for 3G.
3:26 PM
Make Aaron Gant (Mobility Sales Manager) take me out for some field testing in his rig. 200 feet down the road we pick up a WiMAX signal. You need to choose the connection so I choose WiMAX. I’m at 1 bar signal strength.
3:27 PM
Pull into a McDonalds parking lot. Still at 1 bar signal strength. Pull up speedtest.net for a speed test. 0.54 mb/s down, 1.2 mb/s up. Not very impressed. We decide to head towards Portland to see if we can get a better signal.
3:32 PM
Driving through some thick forest on both sides of the road drops my connection. I can see this as a big drawback for mission critical applications. 3G CDMA Rev A is available so I connect to it. Have full bars so I do a speed test on the go. Getting 1.14 mb/s down and 1.3 mb/s up.
3:38 PM
Out of the foliage WiMAX is available again, this time with 2 bars and getting stronger. We stop in a parking lot and we are up to 3 bars WiMAX. Ok speed test on speedtest.net. 6.16 mb/s down and 16.92 mb/s up. That’s more like it, but I wonder why the upload speed is so high.
3:50 PM
We decide to head back towards Clackamas to see what the coverage looks like closer to the office.
3:57 PM
Pulled over at a Church parking lot. Can see obvious cell tower site with at least 3 carriers on there. Let’s see what we find. I’ve got 3 bars for WiMAX. 9.78 mb/s down and 10.35 mb/s up. Streaming videos with ease, this is a very fast connection.
Conclusion
First off, this test makes you really appreciate the 3G CDMA Rev A network. I had full bars everywhere I went, indoors and out, and had fairly consistent speeds of roughly 700k down and 400k up. 4G WiMAX is not going to be for everybody. When you have the right coverage the speed is awesome, but if coverage is spotty you will need to reconnect, search, and eventually need to connect to the 3G network. Not to say that with future hardware the modem won’t automatically roam between 4G and 3G, but for now I would absolutely rule out critical public safety applications.
Mobile vs. Moving
I see this for business/executive use where the user who wants to be “mobile” from site to site, but does not require the connection to be held seamlessly through a “moving” environment…in a car, walking in and out of buildings, etc.
